Introduction to Computer Networks|Course hero helper

A computer network is a group of interconnected devices that can communicate with each other to exchange information and share resources. The devices in a computer network can include computers, servers, printers, and other peripherals, as well as mobile devices such as smartphones and tablets.

Computer networks can be classified into different types based on their size, geographic scope, and communication technologies used. Some of the most common types of computer networks include local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), and personal area networks (PANs).

The communication between devices in a computer network is made possible by using standardized protocols, which define the rules for transmitting data between devices. Some of the most widely used network protocols include the Transmission Control Protocol/Internet Protocol (TCP/IP), the User Datagram Protocol (UDP), and the File Transfer Protocol (FTP).

Computer networks have revolutionized the way we communicate and share information. They have enabled the growth of the internet, which has in turn created new opportunities for communication, commerce, and education. Additionally, computer networks are essential for modern business operations, as they allow organizations to share information, resources, and applications, and to collaborate with partners, customers, and employees.
