Networks Layer Functions And Layer Application Protocols

Computer networks and protocols are essential components of modern computing and communication systems. A computer network is a group of interconnected devices (such as computers, servers, printers, and routers) that are linked together to enable communication and resource sharing. Network protocols are sets of rules and standards that govern how data is transmitted and received over a network. Protocols provide a common language and framework for devices to communicate with each other, ensuring that data is transmitted reliably and efficiently.
