What is Networking?

Definition

Networking is:

  • The connection of multiple devices to share data and resources

  • A system that enables communication between computers

Purpose of Networking

  • Share files and data

  • Access the internet

  • Enable communication between users

  • Share devices such as printers

👉 Networks are essential in modern IT environments.

Types of Networks

1. Local Area Network (LAN)

  • Covers a small area (e.g., office or home)

  • High-speed connections

2. Wide Area Network (WAN)

  • Covers large geographical areas

  • Connects multiple LANs

👉 The internet is an example of a WAN.

Wired Connections

Wired networks use physical cables to connect devices.

Examples

  • Ethernet cables

  • Network switches

Advantages

  • Stable connection

  • Faster speeds

Wireless Connections

Wireless networks use signals instead of cables.

Examples

  • Wi-Fi

  • Bluetooth

Advantages

  • Mobility

  • Convenience

Basic Wireless Setup

  • Enable Wi-Fi on device

  • Select network

  • Enter password

  • Connect

Common Network Issues

  • No internet connection

  • Weak signal

  • Incorrect settings

  • Hardware issues

Basic Troubleshooting

  • Check cables or Wi-Fi connection

  • Restart router

  • Verify settings

  • Move closer to router

👉 These steps help restore connectivity.

Importance of Networking

Networking is important because it:

  • Enables communication

  • Supports business operations

  • Allows resource sharing

  • Provides internet access

Key Notes

  • Networking connects devices for communication

  • LAN and WAN are common network types

  • Wired networks use cables

  • Wireless networks use signals

  • Troubleshooting helps resolve connection issues
