- LAN
- Local Area Networks
- Seen in most offices and schools
- Needs the following hardware to work:
- 1) A network file server- a computer that runs the software needed by the network and stores files
- 2) individual workstations- givs users access to the network and can use the network's software
- 3) a print server is needed if the network of computers wish to sare one computer
- 4) for the network to work, data needs to be sent toand from all parts of the network. this can be done using wires, fiber optics or radio signals
- WAN
- Wide Area Networks
- Used when computers that need to be connectd are in different places
- Need servers tooperate the network, but users connect to it from a distance, often using telephone lines
- they are used by companies who have employees working away from the main sites.
- Network= two or more computers connected together.
- Advantages:
- Software can be shared
- communication is cheap and fast
- Peripherals such as printers can be shared amongst may users
- Disadvantages:
- Cabilling can be expensive to install and replace
- A fault wit the server can prevent the whole network working
- viruses could disable the entire network
- LAN
