(12)What are the important benefits of computer network?

(1)Distribution of Information: 

•  Due to geographical spread, information may be required at different location.
• Example: In case of bank, information of various customers is required to be with each branch and also to make Consolidated Balance Sheet, information would be required from all branches at centralized location.

(2)Resource Sharing:

• Networking helps in sharing of resources.
• Data could be stored at a central location and can be shared across different systems.
• Example: In the case of a CBS, bank data is stored at a Central Data Centre and could be accessed by all branches as well as ATMs.

(3)Improved Computational Power: 

• Through computer networks, processing is distributed among various computer systems.
• This increases computational power of most of the applications.
• For example: processing in an ATM machine in a bank is distributed between ATM machine and the central Computer System in a Bank, thus reducing load on both.

(4)Reliability:

• Computer network improves reliability of the critical applications.
• Example: In a city, there could be multiple ATM machines so that if one ATM fails, one could withdraw money from another ATM.

(5)User communication:

• Computer Networks allow users to communicate using e-mail, video conferencing etc.
