If you want to learn about computer networking, there are a lot of resources available. This guide will help you get started by explaining what computer networking is, and how it works. We’ll also go into detail on the OSI model, Ethernet protocols, data link layer protocols, IPv4 vs IPv6, and more.
What is Computer Networking?
Computer networking is the process of connecting computers together. These connections can either be wired or wireless, depending on the type of network you’re setting up. Computer networks allow users to share information, access resources remotely and communicate with each other across great distances–they’re essential components in everything from businesses to homes.
The most common type of computer network is called local area networks (LANs). A LAN connects multiple computers within close geographic proximity–typically within an office building or campus–to share data over a single connection point (like Ethernet cables). Another popular option is wide area networks (WANs), which connect multiple LANs over long distances using telephone lines or fiber optic cables; this allows people who work at different physical locations from one another to collaborate virtually as if they were all sitting in one room together!
Introduction to the OSI Model and TCP/IP
In this section, we’ll introduce the OSI model and TCP/IP. The OSI Model (Open Systems Interconnection) is a standard that divides computer networking into seven different layers. It’s also known as the DoD Model or ISO/OSI reference model. The TCP/IP protocol stack consists of four layers: application, transport, internet and link layer.
A typical TCP/IP header contains 20 bytes of data; however, only 14 bytes are used for actual data transmission purposes while the remaining 6 bytes are reserved for future use by other protocols such as IPv6 (Internet Protocol version 6). A typical packet size may vary from 64 …
