What Is Networks? by Lihuo

 Networks is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.

A network consists of multiple devices that communicate with one another. It can be as small as two computers or as large as billions of

devices. While a traditional network is comprised of desktop computers, modern networks may include laptops, tablets, Smartphones, televisions, gaming consoles, smart appliances, and other electronics. 

Many types of networks exist, but they fall under two primary categories: LANs and WANs.
