A network is a group of two or more computers or other electronic devices that are interconnected for the purpose of exchanging data and sharing resources. Networks allow computers to communicate with each other and share resources such as printers, files, and internet connections. Networks can be connected through cables, telephone lines, radio waves, satellites, or infrared light beams. There are different types of networks, including:
-
Local Area Network (LAN): A network that is confined to a relatively small area, such as a home, school, or building. Wired LANs are most commonly based on Ethernet technology.
-
Wide Area Network (WAN): A network that covers a larger geographic area, such as a city, country, or even the world. The internet is an example of a WAN.
-
Wireless LAN (WLAN): A LAN that uses wireless technology to connect devices, such as Wi-Fi.
-
Wireless WAN (WWAN): A WAN that uses wireless technology to connect devices, such as cellular networks.
Networks can be used for various purposes, including information storing and sharing, entertainment, and distributed computing. Networks must be physically and logically designed in such a way that makes it possible for the underlying network elements to communicate with each other. This layout of a computer network is known as the computer network architecture. Networking is also important for career development, as it involves exchanging ideas and information between individuals who are connected by a common career.
