Networking systems refer to the interconnected group of computers and devices that communicate with each other to share resources and information. These systems can be local, like a home network, or extensive, like the Internet. They use various protocols to ensure data is transmitted accurately and efficiently. In a networking system, devices such as routers, switches, and servers play crucial roles. Routers direct data traffic between networks, while switches connect devices within a local network. Servers provide resources, such as files or applications, to other devices, enabling collaboration and information sharing among users.
