What are the 4 types of telecommunication networks?

Telecommunication networks are categorized based on their geographical coverage and the technology they use to transmit data. There are four primary types of telecommunication networks:

1. Local Area Network (LAN): LANs are typically confined to a small geographic area such as an office building, school, or home. They are used to connect devices like computers, printers, servers, and other peripherals within a limited space. LANs usually offer high-speed data transfer rates and are commonly set up using Ethernet cables or wireless technologies like Wi-Fi.

2. Wide Area Network (WAN): WANs cover a larger geographical area and connect multiple LANs across cities, countries, or even continents. They utilize various telecommunication technologies such as leased lines, satellite links, fiber optics, and the internet to transmit data over long distances. WANs enable communication between geographically dispersed locations and facilitate access to centralized resources.

3. Metropolitan Area Network (MAN): MANs fall between LANs and WANs in terms of geographic coverage. They span across a metropolitan area or a city, providing high-speed connectivity to entities like businesses, schools, and government organizations within that specific region. MANs can offer higher data transfer rates compared to WANs and are commonly used for interconnecting LANs in different parts of a city.

4. Personal Area Network (PAN): PANs are the smallest and most personal type of network, connecting devices within an individual's workspace or immediate vicinity. They typically involve the interconnection of personal devices like smartphones, tablets, laptops, and wearable technology (e.g., Bluetooth-enabled devices) to facilitate data sharing and communication on a small scale.

These network types vary in their scope, size, and purpose, catering to different communication needs ranging from local connections within a confined space to global connectivity across vast distances. Each type of network plays a vital role in enabling communication and data exchange in various settings, from homes and offices to broader geographical regions and the global internet infrastructure.
