8. 4 ADVANTAGES AND DISADVANTAGES OF LAN Advantages: Computers can share devices such as printers. Which is cheaper than buying a printer for every computer Computers do not need their own hard disk drives which make them cheaper to buy than stand-alone PCs People can save their work on the computer’s file server. This means that they can retrieve their work from any computer in the network People can communicate with each other and transfer data between computer’s easily Link: http://answers.yahoo.com/question/index?qid=20 080914004237AAlPZXT http://answers.yahoo.com/question/index?qid=20 080914004237AAlPZXT
