CHAPTER TWO
OVER ALL EXPERIENCE GAINeD FROM THE INTERNSHIP
2. REASON WHY WE SELECT THE COMPANY
We have chosen the organization because it is one of the leading ICT and information technology
companies in the region and in the country, as well as a leading institution that provides practical
training to students from various universities in the country by providing necessary equipment
And because the institution has rooms that are directly related to the subject we are taking and
also it is located a short distance from our home city.
OUR INTERNSHIP WORKING SECTION
During our stay in the organization, we have chosen networking from the various sectors offered
to us as an alternative, and the reason is Because of our eagerness to put into practice the
network technology we have seen at the theory level because it is one of the sections of the
organization that provides adequate functional training in the organization.
THE WORK FLOW OF NETWORKING DEPARTMENT
The networking unit of the organization divides the work into several stages. These operations
are arranged in stages as follows they receive internet service from a service provider and
manage using different switches. Deploy the managed network to the various offices of the office
as needed. These include monitoring the network and repairing it in the event of a malfunction,
as well as setting up a data center and providing and receiving information to the recipient in a
timely manner.
2.4 OUR TASK DURING THE INTERNSHIP
Once we were in the company and selected the networking unit, the task we were given was to
take the floor plan of one of the buildings of the company and set up an internet connection for
each office and create local area network with different VLANs

MATERIALS AND METHODOLOGY USED
Methodology
For the achievement of our internship we used different approach as the hardness of the project.
Accordingly, the following procedure was used to overcome our difficulty and lastly, we
achieved our project in a good and best manner. Some methods are as listed as follow:
➢ Observation of the site
➢ Free hand sketch of the design
➢ Measurement
➢ Counting no of nodes and users
➢ Drawing the design on Visio software
a) Observation
This is the first thing to start our project by surveying the overall design of the agency which we
aimed to do project or to upgrade current existing LAN design in to new design which solves the
problems listed in the statement of problem of the project. And we physically vested around the
agencies site or bureaus and collect some information to do our next task.
Freehand sketch
The next step before going to design on Visio software in this step we draw the design of agency
on the paper.
b) Measurement
In this step we measured each and every room lengths in addition to cable length from server
room to each access switch. Then from access switch to nodes or end users.
c) Counting
Counting is method which we used to count number of nodes in each room which are functional
and non-functional and number of users how many user is there to solve problem of network
availability of the personals. Then finally we put theProposed Network materials and in the

DESCRIPTIONOF NETWORKING DEVICES WE HAVE USED
SWITCH: is a networking device that records the IP and MAC addresses in a table of all the devices
connected to it. Thus, when a packet is put onto the wire by one device, the switch reads the
destination address information to determine if the destination device is connected to it. If it is,
the switch forwards the packet only to the destination device, sparing the other devices
connected to it from having to read and deal with the traffic. If the switch does not recognize the
destination device, then the switch sends the packet to everything connected to it, thereby
requiring the devices to decide for themselves whether or not packet is for them.
Properties of switch
Figure 2.2 switch
A switch has multiple ports when compared to bridge. It can perform error checking before
forwarding data. Switches are very efficient by forwarding good/error free packets selectively to
correct devices only. Switches can support both layer 2 (based on MAC Address) and layer 3
(Based on IP address) depending on the type of switch.
Router: Is a networking device, commonly specialized hardware that forwards data packets between
computer networks .This creates an overlay internetwork, as a router is connected to two or more
data lines from different networks. When a data packet comes in one of the lines, the router reads
7|Page
the address information in the packet to determine its ultimate destination. Then, using
information in its routing table or routing policy, it directs the packet to the next network on its
journey. Routers perform the traffic directing functions on the Internet. A data packet is typically
forwarded from one router to another through the networks that constitute the internetwork until
it reaches its destination node.
Figure 2.3 Router
Properties of router
A router, like a switch forwards packets based on address. It uses the IP address to forward
packets. This allows the network to go across different protocols.
Routers forward packets based on software while a switch (Layer 3 for example) forwards using
hardware called ASIC (Application Specific Integrated Circuits)
Routers support different WAN technologies but switches do not. The most common home use
for routers is to share a broadband internet connection. The router has a public IP address and
that address is shared with the network. When data comes through the router it is forwarded to
the correct computer.
Registered jack-45 (RJ45)
In wired networks, the most common form of cable connector is the RJ45. Every computer with
networking capabilities has an RJ45 port. This is sometimes called a "network port" or an
"Ethernet port." connects the Unshielded Twisted Pair (UTP)or the Shielded Twisted Pair(STP)
cable. Registered jack-45 (RJ45) refers to a cable termination specification that specifies
physical male and female connectors and the pin assignments of wires-in telephone cables and
other networks that use RJ45 connections.RJ45 (telecommunications) a connector used for
modem connection

Servers:
Servers manage the shared resources on the LAN. The server combines hardware and software to
offer (or serve) network resources. The server hardware may be an ordinary PC or a highperformance unit designed specifically to be a server. The software running on the server will
vary with the type of server. (It is possible for a LAN to have many different types of servers,
each providing for different types of services.) LAN servers often resemble host machines
(mainframes or minicomputers) conceptually and diagrammatically. There is one fundamental
difference between the two: In a host based system, all processing takes places in the central host
machine. Processing is centralized—terminals are totally dependent on the host device for all
processing functions.
A LAN server resembles a host machine in that it also provides shared functions. In the LAN
environment, processing is distributed among all of the intelligent devices—servers, stations and
peripherals. All LANs typically have at least one type of server — print server File Server. The
role of the fileserver is to provide and manage a shared storage area on the network. Although
each computer on the LAN could create and control its own files and then make those files
available to others, it is preferable to provide a centralized storage and management facility.
Using a file server ensures shared files will be available to users when needed. File management
allows multiple users access to files. The file server controls simultaneous access to files,
enforces access rights and restrictions, and provides a directory structure that recognizes file
names and supports the grouping of files. While the primary function of a file server is to
manage the shared storage device(s), it also perform
SOFTWARE APPLICATIONS
We also used some software during our internship period
➢ Microsoft office Visio 2003
➢ Cisco packet tracer
9|Page
VISIO SOFTWARE
This software helps us to develop design of LAN network on computer like we have done it on
paper.it safe software to do network installation because there is on lack of materials for
installation like physical installation.
Cisco packet tracer
It is networking simulation tool to check connectivity of different networking materials like
switch ,router ,computers and we have also able to do configuration of network devices on this
software.
CHALLENGE WE HAVE FACED
Some of the challenges we have faced while performing our work tasks are:➢ lack of transportation system in the morning,
➢ Weak responsibility of the employees to the internship student,
➢ Lack of networking materials
➢ Since the internship is during covid-19 pandemic our activities are limited and we cannot able
In order to follow the covid-19 protocols
B.MEASURE WE HAVE TAKEN TO OVERCOME THE CHALLENGES
To make our internship time suitable and smart we have tried to find a solution for the above
mentioned challenges. As one of the goals of internship program is to make students solution
maker about problems that exist around different company we have taken the following
measures
➢ Getting ready early to get transport

CHAPTER THREE
DETAIL DESIGN AND DESCRIPTION OF PROJECTS WE HAVE DONE
PROJECT TITLE: IMPROVING EXISTING NETWORK OF THE
COMPANY
Summery:
This project is aimed improve and upgrade the existing network infrastructure of the company in
order to provide fast and efficient service for the company workers, customers and government
officials by replacing and adding some equipment Typically, a LAN encompasses computers and
peripherals connected to a server within a small geographic area such as an office building,
home, school that is restricted to smaller physical areas
Network design and installation is concerned on how can interconnect the computers in
organization, how to enable the communication between the device and how to share the
resource between them.
Problem statement and justification
Main issue in the existing network is security problem both physically and logically.
Physically: - Some cables are being damaged.
➢ Uncover places were exist (buildings)
➢ Resources are not wisely used, e.g. access switch, core switch, servers,Rj45
➢ No UPS device for access switches
➢ No power outlets for independent network devices
Logically: - No firewall so that the network is opens for any threats.
➢ Poor path selection, No resource sharing, so needs Security improvement
➢ Connection fluctuation due to path length limitation
➢ A network that is too complex or difficult to maintain cannot function effectively and efficiently.
➢ By considering the problem listed above and using all technical knowledge’s of networking to
solve all the existing problems

PROPOSED PHYSICAL DESIGN AND NETWORK DESCRIPTION OF
THE INCUBATION BUILDING
Proposed Physical Design
Including the network cables, it is an important part of any network design project. Learn best
practices for making sure the physical network is properly configured and the WANs and LANs
are able to support the business needs of your client.we didn’t make any modification on the
13 | P a g e
physical infrastructure on the existing network because we believe that the existing physical
structure is set in the correct manner. Show the blow figure Ground incubation of architecture
Figure 3.1 Incubation ground physical design architecture
Proposed network description
Logical topology is the arrangement of devices on a computer network and how they
communicate with one another. It represents the physical layout of the devices on the network.
There are ways I can propose the existing infrastructure of the network: Using fiber cable as a
backbone or, implements server room on the building. Implementing Fiber optic cable is a better
option than implement server room due to the comparison of cost.
And I add additional two core switch placed in the incubation server room to make each access
switch independent, finally I install a wireless access point.
The proposed network is differing from the existing one by so many aspects listed below:
➢ The first and the main thing is each access switch is independent
➢ Access point (WI-FI) is available
14 | P a g e
➢ Video conference is available
➢ Each expensive network devices will be protected by UPS
➢ Security issue is solved (Firewall)
➢ It will be present patch panel for each access switch
➢ The network is installing hierarchical
➢ present of UPS for access switch
➢ There are no any nodes stop working
LOGICAL DESIGN OF PROPOSED NETWORK
A logical design is virtual design involves arranging data into a series of logical relationships.
Hierarchal network involves three division of layer. These are access layer,
Distribution layer and layer. Fig below explains the existing and proposed logical design

A. Network Scalability
The network we propose is surely Scalable or capable of a system, network, or process to handle
a growing amount of work, or its potential to be enlarged to accommodate that growth on the
incubation center.
B. Network security
Network security is any activity designed to protect the usability and integrity of your network
and data. It includes both hardware and software technologies. Effective network security
manages access to the network. It targets a variety of threats and stops them from entering or
spreading on your network. The network on the incubation center is total dependent on the server
room which is on the agency building. There is no firewall a device in network security system
that monitors and controls incoming and outgoing network traffic based on predetermined
security rules. For this reason network is not secure. In addition to this the company needs to
implement some additional network securities like:
➢ Network access control
➢ Strong anti- malware software
➢ Data loss prevention
➢ Application security
➢ Website security

INTERNSHIP REPORT
C. Video conferencing
A video conference is a live, visual connection between two or more people residing in separate
locations for the purpose of communication. At its simplest, video conferencing provides
transmission of static images and text between two locations.
We proposed Video conferencing because of the following advantages: Higher productivity and
efficiency by eliminating time and space barriers, video conference can be conducted to
communicate with colleagues, customers and partners anytime, anywhere.
D. Network security
There is no UPS (Uninterruptible Power Supply) on the existing network a device that provides
battery backup when the electrical power fails or drops to an unacceptable voltage level. We
recommend ups for each for switches which are now on the incubation center
General Description of the three layers
a) The Core Layer
The core layer is literally the core of the network. At the top of the hierarchy, the core layer is
responsible for transporting large amounts of traffic both reliably and quickly. The only purpose
of the network’s core layer is to switch traffic as fast as possible. The traffic transported across
the core is common to a majority of users. However, remember that user data is processed at the
distribution layer, which forwards the requests to the core if needed. If there is a failure in the
core, every single user can be affected. Therefore, fault tolerance at this layer is an issue. The
core is likely to see large volumes of traffic, so speed and latency are driving concerns here. Let’s
start with some things we don’t want to do:
➢ Don’t do anything to slow down traffic. This includes using access lists, routing between Virtual
local area networks (VLANs) and implementing packet filtering.
➢ Don’t support workgroup access here.
➢ Avoid expanding the core (i.e., adding routers) when the internetwork grows.
➢ Becomes an issue in the core, give preference to upgrades over expansion. Now, there are a few
things that I want to do as I design the core:
17 | P a g e
Downloaded by Addis Abebaw (addisabebaw78@gmail.com)
lOMoAR cPSD| 8746338
BULE HORA UNIVERSIRY
➢ Design with speed in mind. The core should have very little latency.
INTERNSHIP REPORT
➢ Select routing protocols with lower convergence times.
➢ Fast and redundant data-link connectivity is no help if your routing tables are shot!
b) The Distribution Layer
The distribution layer is sometimes referred to as the workgroup layer and is the communication
point between the access layer and the core. The primary functions of the distribution layer are to
provide routing, filtering, and WAN access and to determine how packets can access the core, if
needed. The distribution layer must determine the fastest way that network service requests are
handled for example, how a file request is forwarded to a server. After the distribution layer
determines the best path, it forwards the request to the core layer if necessary. The core layer
then quickly transports the request to the correct service. The distribution layer is the place to
implement policies for the network. Here you can exercise considerable flexibility in defining
network operation. There are several actions that generally should be done at the distribution
layer:
➢ Routing
➢ Implementing tools (such as access lists), packet filtering, and queuing
➢ Implementing security and network policies, including address translation and firewalls
➢ Redistributing between routing protocols, including static routing
➢ Routing between VLANs and other workgroup support functions
➢ Defining broadcast and multicast domains
c) The Access Layer
The access layer controls user and workgroup access to internetwork resources. The access layer
is sometimes referred to as the desktop layer. The network resources most users need The
following are some of the functions to be included at the access layer: will be available locally.
The distribution layer handles any traffic for remote services.
➢ Continued (from distribution layer) use of access control and policies
➢ Creation of separate collision domains (segmentation)

Cisco Packet Tracer is multi-tasking network simulation software that can be used to perform
and analyze various network activities such as implementation of different topologies, selection
of optimum path based on various routing algorithms, creation of appropriate servers, sub
netting, and analysis of various network configuration and troubleshooting commands. In order
to start communication between end user devices and to design a network, we need to select
appropriate networking devices like routers, switches, and hubs and make physical connection by
connecting cables to serial and fast Ethernet ports from the component list of packet tracer.
Networking devices are costly so it is better to perform first on packet tracer to understand the
concept and behavior of the network.
Hardware Requirement
➢ Access Switch
➢ UTP CAT6A
➢ Computer
➢ DHCP server

Network Design
INTERNSHIP REPORT
For interconnectivity of components, network topology describe the physical and logical
appearance and interconnection between arrangement of computers, cables and
other
components in a data communication network and how it can be used for taking a packet from
one device and sending it through the network to another device on a different network. A
network topology is the physical layout of computers, cables, and other components on a
network. There are a number of different network topologies, and a network may be built using
multiple topologies.
The Star Topology is a network topology in which all the clients or machines on the network are
connected through a central device known as switch. Each workstation has a cable that goes from
the network card to the hub or switch device. One of the major benefits of the star topology is
that a break in the cable causes only the workstation that is connected to the cable to go down,
not the entire network as it is with the bus topology The reason why this topology is preferred;➢ Much better performance compared to the bus topology
➢ Easy to connect new nodes without affecting rest of network.
➢ Centralized management or monitoring
➢ Easy to troubleshoot or detect failure
Data analysis and result
design and map the network addresses for each department:
Vlan 10 ------------------192.168.1.0/24
Vlan 20-------------------192.168.2.0/24
Vlan 30--------------------192.168.3.0/24
Create Vlan for Each Department
A VLAN is a logical grouping of network users and resources connected to administratively
defined ports on a switch. When you create VLANs, we are given the ability to create smaller
broadcast domains within a layer 2 switched internetworks by assigning different ports on the
switch to service different sub networks. A VLAN is treated like its own subnet or broadcast

domain, meaning that frames broadcast onto the network are only switched between the ports
logically grouped within the same VLAN. VLANs simplify network management:➢ Network adds, moves, and changes are achieved with ease by just configuring a port into the
appropriate VLAN.
➢ A group of users that need an unusually high level of security can be put into its own VLAN so
that users outside of that VLAN can’t communicate with the group’s users.
➢ As a logical grouping of users by function, VLANs can be considered independent from their
physical or geographic locations.
➢ VLANs greatly enhance network security if implemented correctly

Configuration
a) Configuring IP address DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol used to provide quick, automatic,
and central management for the distribution of IP addresses within a network.
DHCP is also used to configure the proper subnet mask, default gateway, and DNS server
information on the device.

b) Configuring trunk ports
Trucking has been made on the distribution switch as well as the access switches because it is
mandatory to pass VLAN information between the switches. We used the encapsulation dot1q
command in sub interface range configuration mode to apply VLAN id to the sub interfaces.
The 2960 switch only runs the IEEE 802.1q encapsulation method. To configure trunking on
FastEthernet port, use the interface command switchport mode trunk.
The following switch output shows the trunk configuration on interfaces Fa0/4 as set to trunk:
SW4(config)#interface fastEthernet 0/4
SW4(config-if)#switchport mode trunk
C) Routing Configuration
By default, only hosts that are members of the same VLAN can communicate. To change this
and allow inter-VLAN communication, you need a router or a layer 3 switch. I’m going to start
with the router approach.

CHAPTER FOUR
OVERALL BENEFITS GAINED FROM INTERNSHIP
\
Significance of the internship
Internships provide we an opportunity to link theory with practice to see the capacity how I can
make a solution for real world problem to develop both our practical and theoretical knowledge.
The Internship Program allows me an opportunity to understand the Unique environmental
conditions associated with a particular level of government such as regional local administration
and the nonprofit sector. It provides me the career with demonstrated academic competence and
a hands-on experience in the public sector. It gives me an opportunity to do business in group.
Generally the benefits we gained from internship is as follows:
A. PRACTICAL SKILLS
During our practice work, from day to day we tried to learn something new from which we
possess new knowledge/skills.
24 | P a g e

Some of those practical lessons are: -
INTERNSHIP REPORT
➢ In developing our project, we have practiced a lot of theories that previously we had been
learning in the class for three consecutive years.
➢ From our practical works, in terms of local area networking design, we have learned from
where the company’s’ network project start, where it ends, how and when, to do it.
➢ From our internship project work wehave learned each and every devices that are used to
install Local Area Network
➢ Above all, from our internship practice we have upgraded our network configuration skills.
B. UPGRADING THEORETICAL KNOWLEDGE
For doing any practical work, theoretical knowledge is the stepping stone for it. As a result:Wehave upgraded our theoretical knowledge by reading courses that we have learned in the
previous class, so many times over and over.
In addition to academic theoretical knowledge, we have gained different theories in relation to
different business related environment not only that, we have also upgraded our theoretical
knowledge on the important steps needed for installing local area network (LAN).
C. IMPROVING INDUSTRIAL PROBLEM-SOLVING CAPABILITY
This internship has changed our professional level which will be helpful in our activities inside
the company and outside our working station. The knowledge we gained from the course and
from internship period will enhance our personal skill. We have tried to coordinating the theory
(which we have learned from the course) and practice (during internship). As a result we feel that
our quality of work improved and contributing more in the organization for the development of
the existing networkstructure. Some of these areas where we have developed ourselves are
mentioned below:
D. TIME MANAGEMENT
We are now very much competent to proper time management and effective implementation of
activities which will help us from the course of sustainable project management. Moreover, our
supervisor oriented us to time management and encourages to attendee timely in office and
completed all activities within time frame.

INTERNSHIP REPORT
We are able to implement 95% of the activities without delay. Monthly and Weekly work plan,
displayed board furnished with time line of activities in font of desk, day to day activities follow
up helped all of the team member to successfully completion of activities within time
E. TEAM PLAYING SKILLS
Under this topic we try to present the importance of executing personal task in a team. This
means that each member of the team must be responsible for the whole team success and failure.
So, we learned to be more responsible as individual and as a team. Team playing skills we gained
from the internship program includes:Sharing of information between team members. From our internship program we gained the way
of sharing information, knowledge, and experience to take the initiative to keep other team
members informed. That means a team players must share all relevant information to its
members.
We have learned that one team member must care about what the team members are doing and
their contribution to its success. We understood that the knowledge of team is stronger than the
individual persons’ knowledge and it is more effective. We understood even in the future the
knowledge of team is important if we share information and work together
F. LEADERSHIP SKILLS
The internship is an important occasion to practice the assets of leadership. We have increased a
lot about leadership and we saw how important it is for a successful project.
In doing our project, we were able to improve our self-confidence as we have the willingness and
inspiration to face any difficulty in the project. The project helped to grow emotionally and learn
from failure and success. This, in turn, gave us a chance to learn project management, the
technical approach and methodology of a project.
In conclusion, the internship helped us to grasp leadership skills such as self-confidence,
accountability and fair assignation of tasks.
G. UNDERSTANDING ABOUT WORK ETHICS, INDUSTRIAL
PSYCHOLOGY, AND RELATED ISSUES
Work ethics are defined by what you are willing to do when no one is watching you. We have
26 | P a g e
Downloaded by Addis Abebaw (addisabebaw78@gmail.com)
lOMoAR cPSD| 8746338
BULE HORA UNIVERSIRY
INTERNSHIP REPORT
Understood that to work in companies respecting the work ethics is the main criteria of workers.
Each
Worker respects the rules and ethics of the company.
Some of good work ethics are:
➢ The path to what we want to take action.
➢ A positive problem solving or goal attainment
➢ Punctuality
➢ Loyalty
➢ Integrity
➢ Taking responsibility
Respecting collogues etc.
When we first joined the ICT agency, our supervisor gave us orientation on how we should act in
SNNPR ICT agency. And every day we took time to have decent character in our team. Because,
we understood the fact that the more we get close to others in ethical way the more we get
benefit
H. IN TERM OF GAINING ENTREPRENEURSHIP SKILL
What is entrepreneurship and what makes a successful entrepreneur? Entrepreneurship can be
Defined as “how does one person successfully take advantage of a work opportunity, while
Another, equally knowledgeable person does not.” Or “it is the capacity and willingness to
Develop, organize, and manage a business venture along with any of its risks in order to achieve
Profit.” An entrepreneur to be a great entrepreneur must have the following personal skills:
➢ Optimistic thinker
➢ Willingness to take risk
➢ Must have a vision
➢ Motivated to lead
➢ Overcoming fear of failure
➢ The ability to identify consumer’s “pain points”
➢ Endurance

INTERNSHIP REPORT
During in our internship time we have an opportunity to meet with different people and from
Those people we take different ideas on how to be an entrepreneur alone with in our money or
Even when we are working in a company. It helps to us to be optimist in our future task and to
Thinkpositively and also OSTICA working environment had been a good starting place to
enhance our Entrepreneur capabilities. Indeed, we learned a lot on improving critical thinking
and problem solving Skills. The change from school to workplace itself was another learning
opportunity,conditioning us to adapt to change and to be able to take responsibility.
I. INTERPERSONAL COMMUNICATION SKILLS
From our internship program, we have improved our personal communication skills as one of the
most important thing. When we were in the campus, most of the communications that we used
are between level hood/colleagues and it’s via informal way. Besides that, informal
ourcommunication is mostly limited to close friends or our level hood. As a result, there is no
more respect between us. On the top of that we didn’t make good team communication while we
were in the campus. In this internship period, we have improved our ways of communication,
and developed new formal communication skill. With the help of our associates, we have found
many options to develop these skills.
M.WORK ETHICS AND RELATED ISSUES
When we first joined the ICT agency, our supervisor gave us orientation on how we should act in
ICT agency. And every day we took time to have decent character in our team. Because, we
understood the fact that the more we get close to others in ethical way the more we get benefit
from them. When we reach working place the SNNPRS enroll their workers under this two
forms of ethics
➢ Personal ethics: These types of ethics include how someone should act towards other people. It is
highly influenced by our cultural, social, religion and personal thoughts. Some of such ethics
includes: Concern for the wellbeing of others, Honesty, Fairness, Tolerance, Open mindedness,
and Positive thinking.
➢ Professional ethics: include an ethics that a certain task does require. It is an important character
that governs every employee. Disobeying such ethics has consequences. Some of these ethics
are; Punctuality, Office disciplines, Reliability, Honesty, Cooperation, Impartiality, Transparency

and openness, Integrity, Tolerance, Avoiding potential or apparent conflict of interests,
Accountability
N.ENTERPRENURSHIP SKILL
The SNNPRS-CITA working environment had been a good starting place to enhance our
entrepreneur capabilities. Indeed, we learned a lot on improving critical thinking and problemsolving skills. The change from school to workplace itself was another learning opportunity,
conditioning us to adapt to change and to be able to take responsibility.
➢ All in all, we can say that from this internship period in addition to formal academic knowledge
wewere able to gain general purpose life experiences in other aspects. These experiences are
unforgettable and we believe that it shaped our personality and behavior like:➢ It helps us to be optimist in our future task and to think positively
CHAPTER FIVE
CONCLUSION AND RECOMMENDATION
CONCLUSION
Internship Program helps us to know several things. The program upgrades our practical skills in
electrical and computer engineering. This internship program helps us to know and understand
every aspect of the outside environment. In fact what really interesting was we learn how to
create LAN from the scratch by working on everything step by step, so this enable us to come up
with many important experience and skills. So using this practical knowledge and skills thatwe
got during internship have helpedus
to create a soft environment to engage into our own
business in future.
In this internship program we tried to create a good relationship with employees and ask several
questions what is not clear. The other thing we got from this internship program is how to
manage work through this also we have increased our self-confidence, work ethics and how to
work cooperatively with others in the offices, from this we have learnt good values and
principles like politeness , respecting others ,giving decision, punctuality ,fulfilling
responsibilities, giving a good attention to others and like. So we concluded that the internship is

INTERNSHIP REPORT
good opportunity to the student to have enough knowledge that help student in the future, and its
good opportunity to know work environment and to prepares themselves for the future goal and
to have a good Aim before graduation.
RECOMMENDATION
SNNPR-CITA is a successful Company in all direction. It is well organized company. The
company has related to several other companies. The company has a lot of employees and gives
a good opportunity to employees to change their living standard and a company gives job
opportunity for new graduated student special for technology student.
In our internship program we have tried to observe different things but we tried to give some
recommendation about the program. As we know this Internship program are essential to all
electrical and computer students not only electrical students but also essential to all university
student to know the practical world and to adopt the outside environment. But the company has a
poor attention to this program.
The company willingness of this program is good because it can create awareness for young
computer graduate student by supporting them in aspect and create smooth business environment
for those have creative knowledge and skills. But it is not good because all employees are not
interested to show everything and every work in detail because of less knowledge about that
internship peoples need. In our thinking we want to recommend them they must be upgrade their
knowledge about internship program for the student, the company and to our country.
we want to say something about company adviser Mr Ashenafi Yohannes. He is very gentle man
to guide and advice to internship students.
