Creating a network, by connecting computer equipment together, allows the equipment to communicate and share information and resources. In particular, you can:

• Share expensive peripherals, such as printers
• All of the computers can access the same printer.
• Pass data between users without the use of floppy disks 

Files can be copied and accessed across the network, eliminating the time wasted and inconvenience caused by using floppy disks to transfer files. There is also less restriction on the size of file that can be transferred over the network.

Centralize key computer programs, such as finance and accounting programs

It is often important that all users have access to the same program (and not copies of it) so that they can work on it simultaneously (for example, a ticket booking application where one program must be used to ensure that the same tickets are not sold twice). Networking allows offices to have such a central program that all users can access.

Automate backup of critical files.

It is always essential to keep backups of any important files. You can automate this procedure by having a computer program that backs up the files for you. Without a network, you would have to manually copy files, which is time consuming.
