Wide Area Netwrok / WAN
This network covers a large area of communication such as
connecting computers in different countries.
The computers in a WAN are connected by telephone lines or
satellite communication.
The computers in WAN network are accessed by terminals.
The PC needs to be connected to a larger computer also
called as a Host computer.
File transfer data is used to transfer the information
between the personal computer or PC and the larger computer or Host computer.
Transfer of data from PC to host computer is called
uploading while transfer of data from host computer to PC is called downloading.
WAN can cover greater distances than LAN and can connect
computers anywhere in the world.
Data transfer speed is slower than LAN in WAN and WAN also
has greater possibility of data transmission error
