Everything You Need to Know about Computer Communication Networks

Connecting computers to a network is simple, once the hardware components are in place. This guide identifies the hardware that connects computers together in local networks, and local networks to the Internet. Several combinations of hardware that link computers are possible. Connecting systems allows users to share media, files, participate in gaming, and other activities. Computer networking hardware also facilitates access to the Internet, and the wide resources it offers.

An Introduction to the OSI Networking Model

Computer networking is a complicated subject, with many interconnected layers and interactions. To help developers and engineers understand how the various networking components work together, several conceptual models have been developed. The Open Systems Interconnection (OSI) Model is a popular model that divides the networking stack into seven layers. This guide explains the OSI Model and describes each layer. It also lists the tools available for each layer and contrasts the OSI Model with the competing Internet Protocol suite.

Configure Linux as a Router (IP Forwarding)

A computer network is a collection of computer systems that can communicate with each other. In order to communicate with a computer that’s on a different network, a system needs a way to connect to that other network. A router is a system that acts as an intermediary between multiple different networks. It receives traffic from one network that is ultimately destined for another. It identifies where a particular packet should be delivered, then forwards that packet over the appropriate network interface.

What is the Difference Between TCP and UDP?

Many users might not understand the network protocols they are using, but networking is a critical topic for application programmers and architects. In particular, the choice between the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) can drastically alter how an application behaves. This guide introduces both transport protocols and explains the difference between TCP and UDP. It also discusses the advantages of both protocols and when they should be used.
