Key Concepts in Computer Networks

Network Fundamentals

What is a Network?

A network is a collection of interconnected devices that can communicate with each other.

These devices can include computers, printers, servers, and other electronic devices.

Types of Networks

LAN (Local Area Network): Connects devices within a limited geographical area, such as a home or office.

WAN (Wide Area Network): Connects devices over a large geographical area, such as the internet.

MAN (Metropolitan Area Network): Connects devices within a city or metropolitan area.

Network Components

Nodes: Any device connected to a network (e.g., computers, printers, servers).

Network Interface Card (NIC): Allows a device to connect to a network.

Hub: A simple device that connects multiple devices on a network.

Switch: A more intelligent device than a hub, directing traffic between specific devices.

Router: Directs network traffic between different networks.

Network Topologies

Bus: All devices are connected to a single cable.

Star: All devices are connected to a central hub or switch.

Ring: Devices are connected in a closed loop.

Mesh: Every device is connected to every other device.

Network Protocols

TCP/IP (Transmission Control Protocol/Internet Protocol): The foundation of the internet.

HTTP (HyperText Transfer Protocol): Used for transferring data on the World Wide Web.

FTP (File Transfer Protocol): Used for transferring files between computers.

DNS (Domain Name System): Translates domain names (e.g., example.com) into IP addresses.

Network Security

Firewalls: Prevent unauthorized access to a network.

Encryption: Scrambles data to make it unreadable to unauthorized users.

Antivirus software: Protects against malware.

Wireless Networks

Wi-Fi: A popular wireless networking technology.

Bluetooth: A short-range wireless technology for connecting devices.

Network Troubleshooting

Ping: A command-line utility used to test network connectivity.

Traceroute: A command-line utility that shows the path data takes to reach a destination.

The Internet

World Wide Web: A collection of interconnected web pages accessible through the internet.

Web browsers: Software used to access and view web pages (e.g., Chrome, Firefox, Safari).

Search engines: Tools used to find information on the internet (e.g., Google, Bing).
