In computer science, a computer network is a group of computers connected to each other that can share resources and communicate with one another. Networks can be wired or wireless, and they enable data exchange and collaboration between devices. One key component of computer networks is the concept of IP addresses. Every device connected to a network is assigned a unique IP address, which is used to identify and communicate with that device. IP addresses are typically in the form of four numbers separated by periods, such as 192.168.1.1. Another essential element of computer networks is the use of protocols. Protocols are a set of rules and procedures that govern communication between devices on a network. The most common protocol used on the internet is TCP/IP (Transmission Control Protocol/Internet Protocol), which ensures that data packets are transmitted accurately and efficiently across the network. Understanding computer networks is vital in today's interconnected world, as they form the backbone of communication and data exchange between devices. By familiarizing yourself with the basics of computer networks, you can better navigate the digital landscape and utilize network resources effectively.
