Computer communication
Computer communication refers to the exchange of information between two or more computers. It can be achieved using various technologies and protocols, such as:
- Local Area Network (LAN): A LAN is a network of computers that are connected to each other within a limited geographic area, such as a building or campus.
- Wide Area Network (WAN): A WAN is a network of computers that are connected to each other over a large geographic area, such as a city, country, or the entire world. The internet is an example of a WAN.
- Wireless Networks: Wireless networks use radio waves to transmit data between computers. Examples include Wi-F i, Bluetooth, and cellular networks.
- Ethernet: Ethernet is a wired networking technology that is used to connect computers in a LAN.
- TC P/IP: Transmission Control Protocol/Internet Protocol (TCP/IP) is a set of communication protocols that are used to transmit data over the internet and other networks.
- Routing: Routing is the process of sending data from one computer to another over a network. It involves selecting the best path for data transmission based on the network topology and traffic.
- Bandwidth: Bandwidth is the amount of data that can be transmitted over a network in a given time period. It is measured in bits per second (bps), kilo bits per second (Kbps), or megabits per second (Mbps).
Computer communication has revolutionized the way people work and communicate, enabling them to share information and collaborate with others regardless of their physical location. It has also opened up new possibilities for e-commerce, e-learning, and tele medicine, among other fields.
