Computer Networking: Connecting Devices and Sharing Information

Computer networking is the practice of connecting computers and other devices to share resources and information. The fundamental components of a network include routers, switches, and hubs, which help direct data between devices. A local area network (LAN) connects devices within a small area, such as a home or office, while a wide area network (WAN) connects devices over larger distances, like across cities or countries.

Networks can be wired or wireless, with Wi-Fi being a common method for connecting devices without physical cables. Networking protocols like TCP/IP ensure that devices can communicate with each other in a standardized way, enabling seamless data transfer across the internet.

Did You Know?

• Wi-Fi is a wireless networking technology that allows devices to connect to the internet without cables.
• The first computer network, ARPANET, was developed in the 1960s and is the precursor to the internet.
• Routers direct data traffic between devices on a network, ensuring it reaches the correct destination.
• Networks can be private (like a home network) or public (like the internet) depending on their accessibility.
