Local area network
Actually internet is one of the part of computer networks.There are three types of computer networks LAN(Local Area Network)where you can communicate only within some desired distance,MAN(Metropolitan Area Network)where you can communicate within a city,&WAN(Wide Area Network)where you can communicate within the entire world.Internet belongs to the third type.We can also say that Internet is one of the applications of computer networks.
Lan
A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).
A wide area network (WAN) is a telecommunication network that covers a broad area (i.e., any network that links across metropolitan, regional, or national boundaries).
City networks are commonly known as WAN's, or Wide Area Network's.
A network that (a) is composed of different interconnected computer networks and (b) covers an unlimited geographical area. Note: Loosely synonymous with an internet (as opposed to the Internet (with an uppercase "I"), which designates one specific network).
A computer network that spans a long distance and uses specialized computers to connect smaller networks.
The term "geographical area" is somewhat ambiguous. Generally speaking, there are 4 types of networks PAN (Personal Area Network), covers a short range, perhaps 20 foot diameter. This is what a bluetooth network usually is. LAN (Local Area Network), covers a building, and perhaps nearby buildings. A common stand alone office network is one of these. MAN (Metropolitan Area Network), covers a wider area then a LAN, but less then a WAN. This is not a very common term, but is usually something along the lines of a business that has two buildings in the same city, but not very close to each other. WAN (Wide Area Network), any large network span. The internet itself is a form of WAN.
Neither, those terms refer to smaller networks, a LAN being "Local Area Network" used in residential or commercial facilities and a WAN is a Wide Area Network, for instance one that covers an entire town/City, these almost always connect to the greater, Internet
Computer networks can be classified based on their size and scope as follows: Local Area Network (LAN): Covers a small geographic area like a single building or campus. Wide Area Network (WAN): Spans over a large geographical area, often connecting multiple LANs. Metropolitan Area Network (MAN): Intermediate in size between LANs and WANs, covering a city or metropolitan area.
Wide area network (WAN) that is usually a larger network that covers a large geographic area.
Metropolitan Area Network (MAN) covers a larger geographical area than a LAN but smaller than a WAN. It typically connects multiple buildings within a city or town. MANs provide high-speed connectivity and support a larger number of users compared to LANs.
Communication network can be generally viewed as Switched & Broadcast.In switched network comes Circuit & Packet Switched network.Circuit Switched Network are used by Telphone,GSM.Packet Switched network are further sub divided into Datagram & Virtual Circuit.Datagram circuit followed by Internet,IP network whereas Virtual circuit example is ATM .
The 802.11 wireless networks provide wireless access on a local network that generally covers a small area. Cellular WANS, meanwhile, are designed to cover city-wide and even global areas.
A group of two or more computer systems linked together in the same building is called a local area network (LAN). LANs allow the connected devices to share resources like printers, files, and internet connectivity.
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.
