Answer 5_4_4

Question 4

Explain why computer networking has developed rapidly over the last fifteen years.  Your answer should discuss three factors that have stimulated this development and three implications for society.

Reasons for networking:

• Stand-alone machines may contain data that others want to access.  Sending data on floppy disks is not reliable and is slow.  So it made more sense to connect computers to share the data.
• There was also a desire to share data between offices
• There was a desire to share data across the globe.

Implications for society:

• World wide web is excellent library of resources to educate and entertain.
• People can buy goods using their computer (the order takes a fraction of a second to place and have your money out of your account, but for ever and a day to produce the goods).
• Quick access to correct data enables companies to be more productive.
