Hey everyone! 
We all use computer networks daily—WiFi, mobile data, streaming, gaming—but have you ever wondered how data actually moves across networks?
At its core, a computer network is a system of interconnected devices (computers, servers, routers, etc.) that communicate with each other using rules called protocols. The internet, for example, is the largest computer network in the world!
The Basics of How Data Travels
Whenever you send a message, load a website, or stream a video, your data is broken into small packets and sent across the network. Here’s what happens:
Your device breaks down the data into packets.
These packets travel through the network via routers and switches, finding the best path to their destination.
At the other end, the packets reassemble to form the complete data.
Think of it like mailing pieces of a puzzle separately and putting them back together when they arrive!
Types of Networks
Networks come in different forms, including:
-
LAN (Local Area Network): Small-scale, like home or office WiFi.
-
WAN (Wide Area Network): Large-scale, like the internet.
-
Wireless Networks: Like WiFi, allowing devices to connect without cables.
-
Peer-to-Peer Networks: Used in torrenting or blockchain, where devices communicate directlywithout a central server.
