3.9.2.2 Types Of Networking Between Hosts.

Question 1

Define a host.

Answer 1

Device on a network that provides a service. This is often a server, which can
provide services such as file storage, printer sharing and internet access but can also be the clients on a network themselves.

Question 2

Define a client-server network.

Answer 2

In a client-server network, one or more central servers provide services to the clients on the network.

Question 3

Are clients or servers more powerful?

Answer 3

Servers are connected to the network in the same way as clients, but are
often more powerful machines than the clients.

Question 4

Outline the process of a client-server request.

Answer 4

Client requests a service. Server responds with the requested service, this could include file storage, management of emails, user accounts and print queues.

Question 5

What do most organisations allow for in client-server networking? Why is this both beneficial and disadvantageous?

Answer 5

Most schools, colleges and businesses use client-server networks to allow for central
management of clients on the network. This can improve security but requires a fair
degree of expertise to set up and manage.

Question 6

Define a peer-to-peer network.

Answer 6

Do away with the shared server, instead services are provided by the clients themselves.

Question 7

How is status/power amongst the clients in a P2P network determined?

Answer 7

All clients have equal power.

Question 8

Provide an example of a

P2P network.

Answer 8

One computer on the

network might manage print queues, another manage storage and a third manage emails.

Question 9

Outline the primary disadvantage of P2P networking.

Answer 9

All of the clients which provide services must be running in order for the network to be fully operational. If the computer
responsible for managing storage is turned off or faulty, none of the clients on the network can access their files.

Question 10

Outline the advantages or P2P.

Answer 10

More cost effective than client-server - no need for a powerful server to provide services.

Easier to set up and maintain.

Question 11

What type of networking do large file sharing networks use?

Answer 11

P2P, to provide high performance services without the requirement of a server.

Question 12

What must a machine have in order to connect to a network?

Answer 12

A NIC.

Enables a device to connect to a network, whether that’s through a cable or wirelessly.
