Step-by-step explanation:
A computer network is the entire system comprised of devices and paths that allow communication and data exchange between different computers or devices. It includes both the physical components, such as computers, routers, and cables, as well as the software and protocols that enable data transmission and networking functions.
Devices in a computer network can range from personal computers, servers, printers, to mobile devices like smartphones and tablets. Paths refer to the physical connections, such as wired Ethernet cables or wireless connections like Wi-Fi.
Furthermore, software plays a vital role in computer networks with applications like network operating systems, firewalls, and communication protocols like TCP/IP that facilitate efficient data transfer and network management.
