Computer networking is the practice of connecting two or more computing devices together for the purpose of sharing resources, data, and information. At a basic level, computer networking works by transmitting data packets between the connected devices.
A network consists of various components, including:
Nodes or endpoints: These are the devices that are connected to the network, such as computers, printers, servers, routers, and switches.
Transmission medium: This is the physical medium that carries the data packets between the nodes. It can be wired, such as Ethernet cables or fiber optic cables, or wireless, such as Wi-Fi or Bluetooth.
Network protocols: These are the rules and standards that govern how data is transmitted and received over the network. Some examples of network protocols include TCP/IP, HTTP, FTP, and SMTP.
Network topologies: This refers to the physical or logical layout of the network. Examples of network topologies include star, bus, ring, and mesh.
When a device sends data over the network, it breaks the data into small packets and adds addressing information to each packet. The packets are then transmitted over the network, with each node along the way forwarding the packets to the next node until they reach their destination. The destination node reassembles the packets into the original data.
Networks can be designed for various purposes, such as sharing files and resources, communicating via email or instant messaging, accessing the internet, or connecting to cloud services. The design of a network will depend on its intended purpose and the specific needs of its users.
