Editor's Notes
- #34 Advantages Of WAN-Messages can be sent very quickly to anyone else on the network. These messages can have pictures, sounds, or data included with them (called attachments). -Expensive things (such as printers or phone lines to the internet) can be shared by all the computers on the network without having to buy a different peripheral for each computer. -Everyone on the network can use the same data. This avoids problems where some users may have older information than others. -Share information/files over a larger area Disadvantages Of WAN-Setting up a network can be an expensive and complicated experience. The bigger the network the more expensive it is. -Security is a real issue when many different people have the ability to use information from other computers. Protection against hackers and viruses adds more complexity and expense. -Once set up, maintaining a network is a full-time job which requires network supervisors and technicians to be employed. -Information may not meet local needs or interests -Vulnerable to hackers or other outside threats
