Networks - LANs & WANs

Connecting computers and electronic devices to a network offers which of the following advantages?

• Enables sharing of resources and information

• Prevents communication between devices

• Increases hardware costs without benefits

• Limits access to the internet

A Local Area Network (LAN) is different from a Wide Area Network (WAN) because:

• A LAN covers a small geographic area, while a WAN covers a large geographic area.

• A LAN is always wireless, while a WAN is always wired.

• A LAN connects devices over the internet, while a WAN connects devices within a single building.

• A LAN is slower than a WAN.

Routers and switches are needed to connect stand-alone computers into a Local Area Network (LAN) because:

• They enable communication and data sharing between computers within the network.

• They provide internet access to each computer directly without any network.

• They store all the data for the computers in the network.

• They act as firewalls to protect each computer from viruses.
