What is Networking?
Networking refers to the practice of connecting computers and other devices to share resources and information. It enables communication between devices, allowing them to work together efficiently. Networking plays a crucial role in various sectors, including education, business, and entertainment.

Different Types of Networking

1. Local Area Network (LAN)
    • A LAN covers a small geographic area, such as a home, school, or office.
    • It typically uses Ethernet or Wi-Fi to connect devices.
    • High-speed data transfer is a key feature.

2. Wide Area Network (WAN)
    • A WAN spans large geographic areas, often connecting multiple LANs.
    • The Internet is the largest example of a WAN.
    • It may use leased telecommunication lines for connectivity.

3. Metropolitan Area Network (MAN)
    • A MAN covers a larger area than a LAN but is smaller than a WAN, typically a city.
    • It connects multiple LANs within a specific geographic area.
    • Used by organizations to connect their various branches.

4. Personal Area Network (PAN)
    • A PAN is a small network, usually within a range of a few meters.
    • Commonly used to connect personal devices like smartphones, tablets, and laptops.
    • Bluetooth technology is often employed in PANs.

5. Virtual Private Network (VPN)
    • A VPN creates a secure connection over the Internet.
    • It allows users to access a private network remotely.
    • It encrypts data for enhanced security.
Understanding these types of networking helps in choosing the right method for various applications, ensuring efficient and effective communication.
