Instructions: Attempt question one and any other two

Question One

A client wishes you to design a networking device that will interoperate with other devices is portable and the system in which it should work with should be transparent. Explain how the layering approach adopted in the open system interconnection reference model will assist you in this function. (5mks)

List the application of fiber optic cables.

(5mks)

Describe five major protocols used in management of networks. (5mks)

By use of a diagram illustrate the basic communicating model on which computer networks are based and give an example of how it is similar to human communication.

(5mks)

Describe any three common parameters of performance of any transmission media.

(4mks)

Explain three key responsibilities of a network administrator. (6mks)

Question Two

Using the open system interconnection reference model explain how data moves from a computer to the hub the bridge router and finally the internet.

(10mks)

Explain five factors to consider when selecting the type of physical media to display in a LAN.

(5mks)

Question Three

Describe what role a network adapter can play as a connectivity device in networked communications.

(5mks)

Signal picks up unwanted random energy. Explain three such transmission impartment.

(3mks)

A computer network is created when two or more computers are wired together to show information and resources. Briefly explain five other motivations for computer networks.

(5mks)

Differentiate between peer to peer and client-server functional architectures.

(2mks)

Question Four

(i) Differentiate between bounded and unbounded media.

(3mks)

ii) Describe two examples of each of the media discussed in (i) above. (2mks)

A magazine published based in Nairobi has a branch in Kisumu, and one in Mombasa. The company has kept in touch by telephone and courier services. Each office is networked. The networks were implemented five years ago and each has a 10 base 5 Ethernet network. Lately the company has been developing projects that involve teams consisting of members form more than one office. Each office has resources that others do not. The current projects require all of these resources. The networks have frequent cable problem, and each time they have one the entire network goes down until the problem is resolved. The management team would like a networking solution which would offer easier troubleshooting, less down time and WAN communication between sites. They would like the WAN connection to support 256 kbps of data and several telephone conversation. The combination of long distance calls and courier service should be eliminated by the WAN. Management would like the WAN to be able to continue operation even if one of the WAN links fails
Identify at least two items at every site that needs upgrading. (2mks)

What type of WAN connection (link) might you use to connect the three sites to each other.

(2mks)

How many WAN connections will it take to connect the three sites? Show the links in a diagram.

(2mks)

What types of device could be used to connect the multiple signals for both voice and data and put them on the same WAN link? (2mks)

What type of connectivity device should be used to connect the LAN to the multiple paths in the WAN created.

(2mks)
