How to set up the Networks?
Setting Up a LAN:
For a Local Area Network (LAN), use Ethernet as the foundation, connecting computers and servers, either with cables or wirelessly through WiFi. WiFi Access Points (WAPs) help with wireless connections, allowing devices to link up. Servers are usually connected using cables, ensuring a stable connection.
Setting Up a MAN:
A Metropolitan Area Network (MAN) brings together multiple LANs using fibre optics. It works like an internet service provider for a city. MANs can also use wireless connections like microwave or infrared lasers. These networks are often owned by a big organization, mainly serving cities to provide high-speed connections.
Setting Up a WAN:
A Wide Area Network (WAN) connects computers and users in different areas. It combines two or more LANs or MANs. Computers in a WAN are linked using public networks like phone lines, satellites, or leased lines (which can be costly). Routers are used at each end of a leased line to extend the network across locations.
How do these Networks function?
LAN (Local Area Network)
A local area network (LAN) is like a group of computers and other devices that talk to each other using cables or Wi-Fi in a small area. Usually, there is a main computer (server) that stores shared information and programs for all the other computers in that area.
MAN (Metropolitan Area Network)
Imagine several LANs connected using special cables and Wi-Fi in a bigger area, like a city. This is called a metropolitan area network (MAN). It connects to important points in the city’s network and the internet, helping different LANs share information quickly.
WAN (Wide Area Network)
For even larger connections, there is a wide area network (WAN). It’s like connecting one point to another using things like traditional phone lines or modems. Companies that provide this service can be local phone companies or long-distance operators.
