CONNECTIONS

  Connections: A connection in networking refers to a communication channel between two devices or networks. This channel allows the devices to exchange data and communicate with each other. There are several types of connections in networking, including wired connections and wireless connections.

 
1. Wired connections include Ethernet cables, coaxial cables, and optical fiber cables. Ethernet cables are the most common type of wired connection and are used to connect computers, printers, and other devices to local area networks (LANs) and the internet. Coaxial cables are used to connect cable modems and other devices to cable television networks. Optical fiber cables are high-speed, high-bandwidth cables that are used in high-performance networks and data centers.

2. Wireless connections include Wi-Fi, Bluetooth, and cellular networks. Wi-Fi is a popular wireless technology that uses radio waves to connect devices to a network. It is commonly used to connect computers, smartphones, and other devices to the internet in homes and businesses. Bluetooth is a wireless technology that is used to connect devices over short distances, such as in personal area networks. Cellular networks are wireless networks that use cellular towers to connect mobile devices to the internet.

Connections in networking can be either permanent or temporary. Permanent connections, also known as dedicated connections, are always active and provide a constant, reliable communication channel. Temporary connections, also known as dial-up connections, are established only when needed and are often used for remote access or for internet access when a permanent connection is not available.
