A local area network is a network that spans a relatively space and provides services to a small number of people
Local Area Network
Wide area network (WAN) that is usually a larger network that covers a large geographic area.
WAN Wide area network
WAN (Wide Area Network)
City networks are commonly known as WAN's, or Wide Area Network's.
A LAN (Local Area Network) unless it is over a large geographical area then it would be a WAN (Wide Area Network).
A network that covers a large campus or city is typically referred to as a Metropolitan Area Network (MAN). This type of network spans a geographical area larger than a local area network (LAN) but smaller than a wide area network (WAN), typically connecting multiple buildings or sites within a city. MANs are often used by institutions like universities, businesses, or municipalities to facilitate high-speed communication and data sharing across various locations.
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network,It is also used to mean the interconnection of several local area networks by bridging them with backbone lines.
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.
Lan is a local network such as inside a house or building, or a wireless covering an area locally. Wan is a wide area network such as the Internet. This network covers a large area (can include the world). Wan's consist of many local area networks linked together.
LAN stands for "Local Area Network" while it can cover a large area they usually don't. For example an office building generally uses a LAN. And if in a skyscraper that LAN can be quite large. On the same token, if you have a router at your house, and all the computers on that router are connected via ethernet cables. That is also a LAN, but is much smaller.
Network categories can be broadly classified into three main types: LAN (Local Area Network), which connects devices within a limited area like a home or office; WAN (Wide Area Network), which spans large geographical areas, often connecting multiple LANs; and MAN (Metropolitan Area Network), which covers a city or a large campus. Additionally, there are other specialized categories such as VPN (Virtual Private Network) for secure remote access and PAN (Personal Area Network) for personal devices like smartphones and tablets. Each category serves different connectivity needs based on scale, distance, and purpose.
