- 1Client-Server NetworkA client-server network has a powerful computer known as a server which provides all of the services required on a network. These can include roles such as:
> File storage
> Backup
> Application sharing
> Printer management - 2Client-Server NetworksThe client computers are all connected to the server via a network communication device, e.g. switch. In order to access resources such as files, users are required to log on at client computers using a username and password. Once connected to the server, a user will have access to:
> A dedicated amount of private storage space
> Printers
> Files, if permission has been granted
> Software used within the organisation - 3Peer-to-peer NetworkA peer-to-peer network has no central server. Each computer performs its own functions and may share some resources with other computers on the network. A peer-to-peer network is often used in smaller organisations, where as a client-server network is often found in larger organisations.
- 4peer-to-peer NetworksThis type of network is much easier to set up and that it why it is often found in homes & small business. However, each computer has to be maintained individually which can lead to unreliability within the network.
- 5Client-Server Characteristics> Backups, security and anti-virus solutions are managed centrally
> All networking processing is done centrally, providing the users with more processing power
> Data and applications are available from any user
> Software is installed on the server and then can be used by every user
> Large hard disks & lots of memory are required as servers require a lot of processing power
> If the server fails then users have no access to any network resources
> A network manager is usually required to maintain the network and server
> The network can be slowed down if many users are access applications that are run directly from the server. - 6Peer-to-Peer Characteristics> Each user is responsible for:
- Backing up their own data
- Installing & keeping anti-virus software up-to-date on their computer
- Installing software programs on their PC
> All processing is done by each individual computer
> The user has to use the same computer each time in order to access their files and software
> Some users may not be able to access some peripherals due to security settings
> There's no reliance on a single server - if one computer fails, only shared files are lost
> Network traffic is minimal
