General Guidelines
1. A Cover page or title page – You should always attach a title page to your assignment. Use
previous page as your cover sheet and make sure all the details are accurately filled.
2. Attach this brief as the first section of your assignment.
3. All the assignments should be prepared using a word processing software.
4. All the assignments should be printed on A4 sized papers. Use single side printing.
5. Allow 1” for top, bottom , right margins and 1.25” for the left margin of each page.
Word Processing Rules
1.
2.
3.
4.
The font size should be 12 point, and should be in the style of Time New Roman.
Use 1.5 line spacing. Left justify all paragraphs.
Ensure that all the headings are consistent in terms of the font size and font style.
Use footer function in the word processor to insert Your Name, Subject, Assignment No, and
Page Number on each page. This is useful if individual sheets become detached for any
reason.
5. Use word processing application spell check and grammar check function to help editing your
assignment.
Important Points:
1. It is strictly prohibited to use textboxes to add texts in the assignments, except for the
compulsory information. eg: Figures, tables of comparison etc. Adding text boxes in the body
except for the before mentioned compulsory information will result in rejection of your work.
2. Avoid using page borders in your assignment body.
3. Carefully check the hand in date and the instructions given in the assignment. Late
submissions will not be accepted.
4. Ensure that you give yourself enough time to complete the assignment by the due date.
5. Excuses of any nature will not be accepted for failure to hand in the work on time.
6. You must take responsibility for managing your own time effectively.
7. If you are unable to hand in your assignment on time and have valid reasons such as illness,
you may apply (in writing) for an extension.
8. Failure to achieve at least PASS criteria will result in a REFERRAL grade .
9. Non-submission of work without valid reasons will lead to an automatic RE FERRAL. You will
then be asked to complete an alternative assignment.
10. If you use other people’s work or ideas in your assignment, reference them properly using
HARVARD referencing system to avoid plagiarism. You have to provide both in-text citation
and a reference list.
11. If you are proven to be guilty of plagiarism or any academic misconduct, your grade could be
reduced to A REFERRAL or at worst you could be expelled from the course

What is the Network?
A computer network is defined as the connection with at least two or more computers
with wired connection or wireless. It may be a computer server, printer or fingerprint
scanner
Types of computer network
The computer network can be mainly divided into several parts. They are,
1.
2.
3.
4.
5.
6.
Personal Area Network (PAN)
Metropolitan Area Network (MAN)
Wide Area Network (WAN)
Local Area Network (LAN)
Wireless Local Area Network (WLAN)
Campus Area Network (CAN)
Among them, Local Area Network (LAN) and WAN (Wide Area Network) are mostly used.
Local Area Network (LAN)
LAN is the most commonly used network. A LAN is a computer network that connects
computers within a limited area, i.e. locally, through a common communication channel. A
LAN covers two or more computers connected through a server. The two important
technologies involved in this network are Ethernet and Wi-Fi.

Advantages and Disadvantages of Local Area Network (LAN)
Advantages of Local Area Network (LAN)
Internet Sharing:
This is the technique of distributing the internet between computers where all the computers
in an office, school share one internet connection and the main internet cable is connected to
one server by a network switch. (Pooyesh, 1970 )
Resource Sharing:
All resources are connected to one network, and if a computer needs a resource, it can be
shared with another computer. These resources include printers, scanners, modems, and
hardware drivers. Therefore, there is no need to purchase separate resources for each
computer and this cost can be saved. (Pooyesh, 1970 )
Data Security:
The data storage on the server in the network is very secure and if you want to change or
delete the data, you can do it easily from a server computer and other computers can access
the updated data. On the other hand, you can allow specific users to access data on the
network. (Pooyesh, 1970 )
Sharing applications and software:
Applications and software can be easily shared over a LAN. You may use the licensed
software so that any user can use it on the network. Buying a license for each user can cost
the organization a lot of money, so subscription to the software program is easy and at the
lowest price. (Pooyesh, 1970 )
Simple and relatively inexpensive:
The primary benefit of a local area network is that this is quick and easy to set up and
reasonably priced when contrasted to other alternatives; consequently, if an organization
intends to build a network at a minimal price and with flexibility, a local area network is the
ultimate answer. (Prasanna, 2022)
Fast communication:
LAN-connected systems or devices communicate directly at very high rates of speed, based
on the LAN model and Ethernet cabling installed. The most prevalent enabled speeds are 10
Mbps, 100 Mbps, and 1000 Mbps. (Prasanna, 2022)

S.A Hasantha Indrajith Dissanayaka
Networking
Assignment No-01
Disadvantages of Local Area Network (LAN)
Implementation Cost:
Even though LAN saves lots of money in terms of resource sharing, the initial cost involved
in setting up the network is quite high. This is mainly due to the requirement of a special
software that is needed to make a server. In addition to that purchasing of hardware
equipments such as routers, hubs, switches and cables are required for the first time setup.
(Roomi, 2020)
Maintenance:
LAN often faces hardware problems and system failure. Hence, it requires a special
administrator to look after these issues. The administrator needs to be well knowledgeable in
the field of networking and needed at its full time job. (Roomi, 2020)
Area Coverage:
LAN is usually made to cover up a limited distance (up to 10km). Most probably it is operated
in small areas such as in offices, banks and schools. This is because its cabling system cannot
be extended more than a certain range. (Roomi, 2020)
Security:
Since it is rather easy to gain access to programs and other types of data, security concerns
are a big issue in LAN. The sole responsibility to stop unauthorized access is in the hands of
LAN administrators. The LAN administrator has to make sure that the centralized data is
properly secured by implementing correct set of rules and privacy policies on the server.
(Roomi, 2020)

Wireless Local Area Network (WLAN)
WLAN stands for wireless local area network. It is a wireless connection that connects two or
more devices in LAN. WLAN uses access points and routers to make a connection between
devices. Wi-Fi is an example of WLAN where devices are connected wirelessly within a
limited range. WLAN is made within home, office building, computer laboratory, school
building or any college campus. For using Wi-Fi, users need to enter a password for making a
connection to the internet. Wi-Fi connection is made either by using mobile hotspots or by
using a wireless modem or wireless router. (Rehman, n.d.)
Figure 2 Wlan Network
Advantages and Disadvantages of Wide Area Network (WLAN)
Advantages of Wide Area Network (WLAN)
 Wireless LAN helps us to operate many types of network devices.
24
S.A Hasantha Indrajith Dissanayaka
Networking
Assignment No-01
 Setting up this network is very easy and it can also be setup via cable.
 It is easier to use wireless network than wire network.
 Now the use of wireless LAN has increased everywhere, because it is mostly
everywhere such as home, office and mall etc.
Disadvantages of Wide Area Network (WLAN)
 This network is more vulnerable to hackers because it is easy to hack the LAN, so it
becomes necessary for us to put a difficult password in it.
 Wireless interference can impair its speed and stability.
 We need another network device like (repeater) to enlarge its network area.
 Many devices are found more costly.

Wide Area Network (WAN)
WAN (Wide Area Network) is another important computer network that which is spread
across a large geographical area. It is a collection of Local Area Network systems. WAN
(Wide Area Network) is created by interconnecting a large number of Local Area Network
systems. WAN includes the technologies to transmit data, image, audio and video information
over long distances and among different LANs and MANs.
Figure 3Wide Area Network(WAN)
Advantages and Disadvantages of Wide Area Network (WAN)
Advantages of Wide Area Network (WAN)
Covering a large geographical area:
WAN covers a large geographical area of 1000 km or more If your office is in different cities
or countries, you can connect your office branches through WAN. An ISP (Internet Service
Provider) can provide you with leased lines that can connect different branch offices together.
(Rehman, 2021)
Software and Resource Sharing:
Like LAN we can share software applications and other resources like hard disk, RAM with
other users on the internet. In web hosting, we share computer resources between many
websites. (Rehman, 2021)
Global Business:

Everyone who has computer skills can do business online and expand their business globally.
There are many businesses like selling goods and buying stocks through internet. Nowadays
this has become a very popular and easy business. For example Daraz, Ali Express, EBay etc.
(Roomi, 2020)
Many apps for messaging:
With IOT and new LAN technologies, messages are transmitted faster. There are many web
applications like Facebook Messenger, WhatsApp, Skype, etc., through which you can
communicate with friends through text, voice and video chat. (Rehman, 2021)
Disadvantages of Wide Area Network (WAN)
High cost of Installation:
Setting up a WAN for the first time in the office costs more. That may include purchasing
routers, switches, and additional security software. (Rehman, 2021)
Troubleshooting Issues:
WAN covers a very large area and troubleshooting it is a very difficult task. Many WAN
wires go under the sea and sometimes the wires break. It takes a lot of effort to reset those
broken wires. (Rehman, 2021)
Server down and disconnection issue:
ISP faces problems due to electricity supply .Customers often face connectivity issues or slow
Internet speed issues. The solution to this is to purchase a dedicated line from ISP. (Rehman,
2021)

IEEE Standards for Local Area Network (LAN)
A local area network (LAN) is a computer network that connects only a small local area
network, such as a school, home, office, or small network. Currently, most LANs are based on
IEEE 802.3 Ethernet technology, using devices such as hubs and switching devices, with data
transfer rates of 10, 100, or 1000 Megabits per second (Mbps). (Khalaf, 2015)
IEEE Standards for Wide Area Network (WAN)
The plug-and-play characteristics of Ethernet provide a unique opportunity for service
providers to-offer a variety of innovative and affordable application-centric services, resulting
in a much broader networking culture. Before that can really happen, Ethernet has to
overcome some challenging obstacles and prove efficient support of SLAs, at least similar to
that offered by traditional layer 2 WAN technologies. In this article we describe some of the
most commonly used WAN transport technologies. We compare Ethernet WAN transport to
these traditional WAN technologies. We discuss QoS, CAM, security, and resilience issues.
Pros and cons of Ethernet WAN transport are also enumerated. (Meddeb, 2015)
Summary
Also, Star Topology can be named as the best topology that can be used for this. The main
reason for this In a star network, every host is connected to a central hub. In its simplest
form, one central hub acts as a conduit to transmit messages

Network Topology
What is the Network Topology
A Network Topology is the arrangement with which computer systems or network devices
are connected to each other. Topologies may define both physical and logical aspect of the
network. Both logical and physical topologies could be same or different in a same network.
(network_topologies, 2022)
Types of Network Topologies
Bus Topology
Figure 4Bus Topology
A bus topology is a network where computers and network devices are connected by a single
cable. When it has extractly two end points, then it is called Bus Topology. Bus Topology
transmit data only in one direction. Easy to connect a computer or peripheral to a bus topology
but entire network shutdown if there is a break down in the main cable.

Star Topology
Figure 5Star Topology
In this type of topology all the computers are connected to a single hub or switch through a
cable. This switch is central node and all others nodes are connected to the central node. Every
node has it own dedicated connection to hub. Easy to install a new node but requires more
cable length than bus topology .therefore more expensive than bus topology

Ring Topology
Figure 6Ring Topology
A ring network is similar to a bus network, but it has a circular structure — every node is
connected to the other node on each side, and the first node is connected to the last. A ring
network operates in a half-duplex mode, which means that data in your network travels
sequentially in one direction. A ring network also uses coaxial cables similar to bus network
topology but it is faster than the bus network. Modern days high speed LANs made this
topology is less popular.

Mesh Topology
Figure 7Mesh Topology
In a mesh network topology, every node is connected to the other node . There are partial mesh
and full mesh networks. A partial mesh has at least two nodes connected to other nodes in the
network. In a full mesh, every station is connected to all other nodes. Mesh networks ensure a
continuous data transfer. If one node fails, other nodes can still transfer your data. Setting up a
mesh network can be expensive. You would need to create multiple connections and purchase
a lot of cable. (Nakivo, 2021)

Tree Topology
Figure 8Tree Topology
A tree topology is a more complex version of a star network. It allows you to bring together
multiple star networks by connecting their switches. Every switch has a port, and you can
connect several stations to those ports. Then you can connect those switches directly to the
main switch (Nakivo, 2021)

What is the Network Protocol?
Types of Network Protocol
Transmission Control Protocol (TCP)
Figure 9Transmission Control Protocol (TCP)
TCP receives messages from an application/server, splits them into packets and forwards them
to network devices - switches, routers, security gateways - where TCP numbers each packet
and reassembles them before delivering them to the application/server recipient. Because it is
connection-oriented, it ensures that a connection is established and maintained between the
sending and receiving application/servers until the exchange is complete.

Internet Protocol (IP)
Figure 10 Internet Protocol (IP)
Internet Protocol is a connectionless and unreliable protocol. It does not guarantee the
successful transmission of data. To make it reliable, it must be paired with a reliable protocol
like TCP at the transport layer. Important points here,
1. The length of the datagram is variable.
2. Datagram is divided into two parts, header and data.
3. The length of the header is 20 to 60 bytes.
4. The header contains information for routing and delivery of the packet. (Protocols,
2022)

User Datagram Protocol (UDP)
Figure 11User Datagram Protocol (UDP)
Like IP, UDP is connectionless and unreliable protocol. It doesn’t require making a
connection with the host to exchange data. Since UDP is unreliable protocol, there is no
mechanism for ensuring that data sent is received. UDP transmits the data in form of a
datagram.

What is the Network Device
Hardware devices that are used to connect computers, printers, fax machines and other
electronic devices to a network are called network devices. These devices transfer data in a
fast, secure and correct way over same or different networks. Some devices are installed on the
device, like NIC card or RJ45 connector, whereas some are part of the network, like router,
switch, etc. Let us find some of these devices in more details.
Types of Network Devices
Router
Figure 14Router
A router is a network layer hardware device that transmits data from one LAN to another if
both networks support the same set of protocols. So a router is typically connected to at least
two LANs and the internet service provider (ISP). It receives its data in the form of packets,
which are data frames with their destination address added. Router also strengthens the signals
before transmitting them. Therefore that it is also introducing as repeater.

Switch is a network device that connects other devices to Ethernet networks through twisted
pair cables. It uses packet switching technique to receive, store and forward data packets on
the network. The switch maintains a list of network addresses of all the devices connected to
it. (Anon, 2022)

Gateway
Figure 16Gateway
Gateway is a network device used to connect two or more dissimilar networks. In networking
parlance, networks that use different protocols are dissimilar networks. A gateway usually is a
computer with multiple NICs connected to different networks. A gateway can also be
configured completely using software. As networks connect to a different network through
gateways, these gateways are usually hosts or end points of the network. (Anon, 2022)

Figure 17Ethernet Card
Ethernet card, also known as network interface card (NIC), is a hardware component used by
computers to connect to Ethernet LAN and communicate with other devices on the LAN. The
earliest Ethernet cards were external to the system and needed to be installed manually. In
modern computer systems, it is an internal hardware component. The NIC has RJ45 socket
where network cable is physically plugged in. (Anon, 2022)

RJ45 Connectors
Figure 18RJ45 Connectors
RJ45 is the acronym for Registered Jack 45. RJ45 connector is an 8-pin jack used by devices
to physically connect to Ethernet based local area networks (LANs). Ethernet is a technology
that defines protocols for establishing a LAN. The cable used for Ethernet LANs are twisted
pair ones and have RJ45 connector pins at both ends. These pins go into the corresponding
socket on devices and connect the device to the network.
What is the Server
A server is a computer, a device or a program that is dedicated to managing network resources.
They are called that because they “server” another computer, device, or program called “client”
to which they provide functionality. There are a number of categories of servers, including
print servers, file servers, network servers and database servers. In theory, whenever computers
share resources with client machines they are considered servers. However, servers are often
referred to as dedicated because they carry out hardly any other tasks apart from their server

What is the Network Software
Network software is a term that represents any software for networking that helps a network
administrators perform a specific operation with ease. The term 'network software' can include
a wide range of software solutions, each of which offering a specific function that together
helps network admins gain complete control over their IT infrastructure. Network software
offers capabilities to monitor network health, measure performance, anticipate potential
outages, take proactive decisions, and to manage and resolve network faults. Network software
also enables you to visualize the network to understand its architecture, and secure your IT
infrastructure from attacks.
Traditional networks were hardware based with software embedded. With the advent of
Software – Defined Networking (SDN), software is separated from the hardware thus making
it more adaptable to the ever-changing nature of the computer network. (software, 2022)

Active directory
Active Directory (AD) is a database and set of services that connect users with the network
resources they need to get their work done.The database (or directory) contains critical
information about your environment, including what users and computers there are and who’s
allowed to do what. For example, the database might list 100 user accounts with details like
each person’s job title, phone number and password. It will also record their permissions. The
services control much of the activity that goes on in your IT environment. In particular, they

What is the Network Plane?
A plane, in a networking context, is one of three integral components of a telecommunications
architecture. These three elements -- the data plane, the control plane and the management
plane – can be thought of as different areas of operations. Each plane carries a different type of
traffic and is conceptually (and often in reality) an overlay network (a telecommunications
network that runs independently on top of another one, although supported by its
infrastructure).The data plane (sometimes known as the user plane, forwarding plane, carrier
plane or bearer plane) carries the network user traffic. The control plane carries signaling
traffic. Control packets originate from or are destined for a router. The management plane,
which carries administrative traffic, is considered a subset of the control plane. In conventional
networking, all three planes are implemented in the firmware of routers and switches. Softwaredefined networking (SDN) decouples the data and control planes, removes the control plane
from network hardware and implements it in software instead, which enables programmatic
access and, as a result, makes network administration much more flexible. (Contributor, 2022)

How to improve network performance
 Determine that your network is at fault
Is your network actually slow, or do you just have slow computers? Make sure that the sluggish
response time is more than just a localized issue before springing for an infrastructure upgrade.
 Update software and firmware
Advancements in technology and the software that runs on it don’t always keep pace with each
other. You may have new programs running on old machines, or old programs running on new
ones either way, it’s unlikely they’ll work well together.If you’re tied to an old software system
simply because that’s the way it’s always been done, it may be high time you set it aside in
favor of something more compatible with current technology. Otherwise, your fondness for the
software of yore could strand your business in the Stone Age.
 Monitor for bottlenecks
Network monitoring is critical for diagnosing any range of potential bottlenecks or traffic jams
in your network. For instance, system backups typically absorb a large quantity of resources.
Because of this, most networks run their backups at night, when employees are out of the office.
 Check for viruses or system defects
Speaking of viruses, malware is known for slowing down networks and inhibiting workflows.
If you suspect your network slowdown might be the result of malicious network activity, you
should have an emergency IT specialist run a check on the situation right away. Slowdowns
can also be the result of different network components growing old and defective. It’s often
relatively painless to replace these broken components, rather than upgrade the entire network.
 Use VLANs to segment low-priority traffic
VLANs (Virtual Local Area Networks) are an excellent way to partition your network
resources such that the most critical traffic receives the highest priority. Essentially, a VLAN
offers the benefits of a completely separate network, without having to rewire the entire office.
You can group VLANs based on computer use and function, even if they’re in separate parts
of the office.
VLANs can also improve security by segmenting your systems from each other. That way,
even if one part of your network becomes compromised, the VLAN can act as a barrier, keeping
other parts of the network safe
