What’s a Network
The dictionary defines the word network as “a group or system of interconnected people or things.” Similarly, in the computer world, the term network means two or more connected computers that can share resources such as data and applications, office machines, an Internet connection
Above image shows a really basic network made up of only two host computers connected, they share resources such as files and even a printer hooked up to one of the hosts. This two hosts “talk” to each other using a computer language called binary code, which consists of lots of 1s and 0s in a specific order that describes exactly what they want to “say.”
Next, I’m going to tell you about local area networks, how they work, and even how we can connect LANs together.
