Computer networks are an integral part of our modern world, enabling communication and data exchange between different devices. Types of computer networks differ in terms of their scope, size, and applications. In this brief article, we'll familiarize ourselves with the basic types of networks to understand how they are utilized.

List of main computer networks

LAN

A LAN (Local Area Network) is a relatively small network that covers a limited area, such as an office, home, or school.

WLAN

A WLAN (Wireless Local Area Network) is an extension of a LAN that operates wirelessly using Wi-Fi technology. It allows devices like TVs, smartphones, and laptops to connect without the need for cables. Popular in homes, cafes, airports, and other public places.

WAN

A WAN (Wide Area Network) covers large geographic areas, such as countries or continents. It's used to connect local networks, enabling communication over long distances. The Internet is an example of a global WAN.

MAN

A MAN (Metropolitan Area Network) is an intermediary network type, larger than LAN but smaller than WAN. It covers a city or region and is often used by businesses and institutions in large cities.

VPN

A VPN (Virtual Private Network) is used to protect data privacy and allows access to a company's network from any location worldwide.

Summary

Computer networks differ in scope and application, facilitating effective communication and resource sharing. LANs operate locally in small areas, while WANs and MANs cover larger regions. WLANs enable wireless connections, and VPNs ensure secure access to remote resources. Understanding these basic network types aids in everyday use of computer technology.
