IP address, also called the IPv4Address in the command prompt in Windows 7,
is 192.168.1.4
6. Identify MAC address of a computer of your choice. Support your answer with an
appropriate screenshot. (3)
MAC address, also called the Physical Address in the command prompt, is 84:3A:4B:79:26:c4
2. Communication & Networking
a. List technical steps required for setting up a wireless network in a home-setting
(4)
1. Equipment Needed: Internet Connection (in this example internet is provide
via Satellite connection) with SAT Cable, Modem with power supply,
Wireless router (in this example the router is a N300 Wireless Router) with
power supply, Ethernet Cable. Each set up may vary slightly dependent on
equipment being used.
2. Start with all equipment off.
3. Connect one end of the Ethernet cable to the modem and the other end to the
internet port on the router. It is now common that most modems and
routers have these ports labeled.
4. Plug in and turn on the modem. If your modem has a battery backup, first
remove and reinsert the battery before connecting the modem to the power.

It is recommended to wait approximately 2 minutes until the modem is fully
turned on.
Connect the power adapter to the router, then plug it into the power outlet.
Make sure the Power On/Off button is in the ON position (pushed in). Wait
until the wireless LED turns solid green.
Connect the router to a computer. It is common that the computer will
identify the new network connection and ask if a connection is desired.
Follow the prompts selecting the Network Name (for this example it is
NETGEAR) and the Network Password. The Network Name is also the
Service Set Identifier or SSID. If not prompted then a manual setup is
possible. Connect wirelessly by going to a utility software that manages
wireless connections on the computer. Look for the preset NETGEAR
wireless network name and select it.
Enter the password.
Click Connect.
Open a browser.
b. List the key differences between
1. Ring and Star topologies (4)
i Configuration of networks – RING topology – connects all
devices to each other. STAR topology - has a central connection
point. All devices hang off one device.
ii Amount of cabling (dependent) – Initially RING topologies
required less cabling then STAR topologies. Now with wireless
connectivity option the amount of cabling used in a STAR
topologies can be greatly reduced.
iii Effects of device dropping off the network – RING topology – if
one device falls off the network then the entire network goes
down. STAR topology – if one device falls off the network then
only that device is affected.
2. PAN and WAN (4)
i Geographical scope – PAN is a Personal Area Network and
typically has a reach of about 30 feet or 10 meters. A WAN is a
Wide Area Network and typically covers a large geographical
area. For example the internet is the world’s largest wide area
network.
ii Size – PAN is typically one network. WAN typically consists of
several smaller networks, which may use different computer
platforms and network technologies.
3. Client-server and Peer-to-peer networks (4)
i Network Configuration – In a CLIENT-SERVER network a
server is present. In a PEER-TO-PEER network there is no
server.
4.
Coaxial cable and Fiber optic cable (4)
i
Method of Transfer – COAXIAL CABLE – Digital information
is transferred via an electromagnetic wave. In FIBER OPTIC
CABLE – Digital information is transferred via light and glass.
ii Speed – FIBER OPTIC CABLE has a greater bandwidth than
COAXIAL CABLE.
iii Cable Sensitivity – COAXIAL CABLE bend better. FIBER
OPTIC CABLE can cut out or distort if bend is great or cable
gets twisted or kinked.
.
3. Website Design
a. Design and develop a Website of your own based on a specific theme, using the
space provided by the University of Tennessee. (10)
a This website uses the Urban color scheme and the Tabs website
template. They cover aspects of information currently not covered on
the SCPLS website. These pages cover the Geek the Library Campaign,
Affordable Care Act, SCPLS Wishlist, Partner Spotlight. Two of these
pages are creating awareness of the role of the library system within the
community. One page provides information on a national scheme for
healthcare insurance and the other lets the community know of another
way it can contribute to the success of programming. The System
Director has agreed that these pages will be added to the Sevier County
Public Library System once converted into wordpress.
b. Using Unix account provided by the UT, upload content / material /
information that you think is relevant to the theme of your Website. (10) Submit
the link of your Website as part of your answer.
ABrueland Unix Website
4. Database Basics
a. List the key differences between spreadsheet and databases (4) (Joan 2010)
i. Difference in Use – Spreadsheets are typically applications for tabulating
data, generating reports or charts; while databases are for the large
storage of data that will be retrieved by users.
ii. Amount of Data – Spreadsheets in comparison to databases handle a
smaller amount of data.
iii. Difference in way data is edited & accessed – Spreadsheets are
applications, while databases are collections of related data that require
an application to access and manipulate the data.
iv. Entry of data – In spreadsheets the data is typically entered in by people.
In databases the data is typically entered or modified via an application.
b. Explain the application of databases for Dashboards (4)
i. Dashboards are user interfaces that present information such as key
performance indicators. They are the interfaces that is part of OLAP
(online analytical processing), which is a system consisting of computer
hardware, database software, and analytical tools that are optimized for
analyzing and manipulating data.
c. Explain the key features of the following types of databases:
i. Hierarchical (2) – Allows for one-to-one and one-to-many relationships
linked in a hierarchical or tree structure. Parent to child or Parent to
many children. (Database Models n.d.)
ii. Networked (2) – Allows for one-to-one and one-to-many as well as
many-to-many relationships. Parent to child, Parent to many children,
more than one Parent per child (Database Models n.d.)
iii. Relational (2) – Relationships are specified by joining common data
stored in the fields of records in different tables. The way a relational
database establishes relationships allows the tale to be essentially
independent, but the tables can be joined for a particular task.
Relationships can be added, changed, deleted on demand making this
database model very flexible. (book)
d. Illustrate the following relationships
i. One-to-One relationship (2) –
Parent
Child
ii.
One-to-Many relationship (2) –
Parent
Child
Child
Child
iii. Many-to-Many relationship (2) –
Parent
Parent
Child
Child
Child
Child
5. Entity-relationship Diagram
a. Identify and list entities in the following E-R diagram (4)
ENTITIES – Some identifiable object relevant to the system being built.
1. Customer
2. Order
b. Identify and list attributes in the following E-R diagram (4)
ATTRIBUTES – A characteristic of an Entity.
1. Customer ID
2. Name
3. Address
4. City_State_Zip
5. Discount
6. Order Number
7. Order Date
8. Promised Date
c. Identify and list relationship and cardinality of relationship in the following E-R
diagram (4)
CARDINALITY OF ONE-TO-ONE
1. Customer to Customer ID
2. Customer to Name
3. Customer to Address
4. Customer to City_State_Zip
5. Customer to Discount
6. Order to Order Number
7. Order to Order Date
8. Order to Promised Date
CARDINALITY OF ONE-TO-MANY
1. Customer to Order
d. Identify primary keys in the following E-R diagram (4)
PRIMARY KEYS
1. Customer ID
2. Order Number
e. Tabularize the following E-R diagram (4) - I have been unsuccessful in getting
the one-to-many to display. Access says it is there but the infinite sign does not
display. It needs to show that one customer can place many orders.
