Which of the following are the main benefits of networking computers and devices rather than using a number of stand-alone computers?
1.Devices, such as printers, can be shared, thus reducing costs
2.Licences to run software on networks are often cheaper than buying licences for an equivalent number of stand-alone computers
3.Users cannot share files and data
4.Access to reliable data that comes from a central source, such as a file server
A1 & 3 only
B2, 3 & 4 only
C1, 2, 3 & 4
D1, 2 & 4 only ✓ Correct
Correct answer: (D) 1, 2 & 4 only
Explanation
Statements 1, 2 and 4 are correct: networking lets devices like printers be shared, licences be cheaper, and reliable data be accessed from a central source.
Statement 3 is wrong because networking actually lets users share files and data, not prevent it.
Sharing one printer across many computers cuts hardware costs.
Network or site licences are often cheaper than buying separate licences for each stand-alone machine.
A central file server gives users consistent and reliable access to shared data.
Networking also simplifies central backup and security management.
