Discuss any three computer networks.

1. Local Area Network (LAN): A LAN is a network that covers a small geographic area, such as a single building or a campus. It typically connects computers and devices within a limited area, allowing them to share resources such as files, printers, and internet access. LANs are commonly used in homes, schools, and businesses to facilitate communication and collaboration among users.

2. Wide Area Network (WAN): A WAN is a network that covers a large geographic area, such as a city, country, or even multiple countries. It connects multiple LANs and other networks together, allowing users in different locations to communicate and share resources. WANs are often used by organizations with multiple offices or branches to facilitate communication and data transfer between locations.

3. Wireless Network: A wireless network uses radio waves or infrared signals to transmit data between devices without the need for physical cables. Wireless networks are commonly used in homes, offices, and public spaces to provide internet access to users without the constraints of wired connections. They can be implemented as LANs or WANs, depending on the size and scope of the network. Wireless networks offer flexibility and mobility, allowing users to connect to the network from anywhere within range of the signal.
