Kinds of Network

HNC COMPUTING - Network Concepts

1

Aims

Understand the terms Client and Server

Discuss Peer to Peer Networks (Workgroup based)

Discuss Client-Server Networks (Domain based)

Gain knowledge into the difference between Workgroup based and Domain based

2

Understand the terms Client

Client

This is a computer that uses resources on the network.

A printer client for instance, is a computer that uses a network printer.

3

4

Understand the terms Server

Server

This is a computer or device with a computer hidden inside, that has resources used by other devices on the network

For example a file server is a computer that stores files used by other computers

5

Understand the terms Client and Server

The server makes resources available to the network, and a client uses the resources.

6

Peer to Peer Networks

In a peer to peer network all computers are equal.

All computers function as both the client and the server.

Peer to peer networks can be set up so that some computers only share their resources and some computers only use resources.

Each computer is administered individually

P2P –identify the benefits?

8

Client-Server Networks

Typically more expensive and difficult to set compared with peer to peer networks.

Provide more sophisticated administration and security.

All resources are managed centrally on dedicated servers.

Require a network operating system like Windows NT / Unix

Makes use of a domain to administer user groups

Client- Server – identify the benefits?

10

The difference between Workgroup based and Domain based

Peer to Peer Client-Server

Ideal size of

network is?

Good for small networks –

15 Workstations are under

Good for medium to large

network

Hardware

requirements?

No dedicated file server is

needed

At least one server is

needed

What kind of

OS is

Required?

XP HOME, Professional on

all machines

NOS is required on the

server – at OS on other

machines is limited

How much

Training is

required?

Little training is needed

users administer their own

machine

Systems administrator must

be trained

Who controls

Resources?

Each computer’s user has

control over resources

System administrator has

control over sharing

Conclusion

Gained an understanding into the terms Client and Server

Discussed Peer to Peer Networks (Workgroup based)

Discussed Client-Server Networks (Domain based)

Gained knowledge into the difference between Workgroup based and Domain based
