Network Types

Depending on your company's needs, your organization can span networks of different sizes and types. For example, a single local area network (LAN) that connects a few computers for sharing files and printers might use Ethernet, but a WAN that connects computers in a worldwide organization might use a backbone over T1 lines.

You need to consider reliability when choosing which type of network to use. For example, satellite connections have very high bandwidth but may not be reliable; an Ethernet network with a lower bandwidth may be more reliable.
