Categories of Network

LAN (Local Area Network)

What is Local Area Network: The Local Area Network (LAN) is network that is usually contained within a room, floor, or building.

A Local Area Network is typically privately owned and links the devices during a single office, building or campus of up to a couple of kilo meters in size.

LAN (LOCAL AREA NETWORK)

counting on the requirements of a corporation and therefore the sort of technology used, a LAN (Area of Local Network) are often as simple as two PCs and printer in someone’s whole office or it can extend throughout a corporation and include voice, sound, and video peripherals.

A Local Area Network (LAN) may be a network that's confined to a comparatively small area. it's generally limited to a geographical area like an article lab, school, or building. Rarely are LAN (Local Area Network) computers quite a mile apart.

Characteristics of LAN (Local Area Network)

The defining Characteristics of Area of Local Network, in contrast to Wide Area Networks (WANs), include their much higher data transfer rates, smaller geographic range, and lack of a requirement for leased telecommunication lines.

Initially, LANs were limited to a rage of 185 meters or 600 feet and could not include more than 30 computers. Today, a LAN (Local Area Network) could connect a max of 1024 computers at a max distance of 900 meters or 2700 feet.

LANs are designed to permit resources to be shared between personal computers or workstations. The resource to be shared can include hardware, software, or data.

A common example of LAN (Network of Local Area), found in many business environments, links a piece group of task-related computers, for instance, engineering workstations or accounting PCs.

One of the computers could also be given an outsized capacity disc drive and become a server to the opposite clients. Software can be stored on this central server and used as required by the entire group. during this example, the dimensions of the LAN could also be determined by licensing restriction on the amount of users per copy of software, or by restrictions on the amount of users licensed to access the OS.

In addition to size, LANs are distinguished form other sorts of networks by their transmission media and topology. In general, given LAN (Area of Local Network) will use only one type of transmission medium. The most common LAN topologies are bus topology, ring topology, and star topology. Traditionally, LANs have data rates within the 4 to 16 MBPS range. Today speeds are increasing, can reach 100 MBPS to 1 GBPS.

In a typical LAN (Area of Local Network) configuration, one computer is designated because the digital computer. It stores all of the software that controls the network, also because the software which will be shared by the computers attached to the network. 

Computers connected to the digital computer are called workstations. The workstations can be less powerful that the file server, and they may have additional software on their hard drivers.

On most LANs, cable are used to connect the network interface cards in each computer.

Ethernet over unshielded twisted pair cabling, and wi-fi are the 2 commonest technologies currently, but ARCNET, Token Ring and lots of other are utilized in the past.

MAN (Metropolitan Area Network)

What is MAN: A MAN (Metropolitan Area Network) may be a Metropolitan Area Network, which is an intermediate step between LAN (Network of Local Area) and wan. 

Typically, a WAN (Wide Area Network) is kept to at least one geographical area. A campus network that connects multiple buildings in a given area is an example of a MAN (Network of Metropolitan Area).

MAN (Metropolitan Area Network)

A metropolitan area network is meant to increase over a whole city. it's going to be one network like a cable television network, or it's going to be a way of connecting variety of LANs into a bigger network in order that resources could also be shared LAN-to-LAN also as device-to-device.

Area Metropolitan Network (MANs) are large computer networks usually spanning a city. They typically use wireless infrastructure or glass fiber connections to link their sites.

A Metropolitan Area Network (MANs) covers larger geographic areas, such as cities or school districts. By interconnecting smaller networks within an outsized geographic area, information is certainly disseminated throughout the network, Local libraries and government agencies often use an individual to connect to citizens and personal industries.

A MAN (Metropolitan Area Network) could also be wholly owned and operated by a personal company, or it's going to be a service provided by a public company, like an area telephone service. 

Many telephone companies provide a well-liked MAN (Metropolitan of Network Area) service called Switched Multi-Megabit Data Services (SMDS).

A MAN is optimized for a bigger geographic area than may be a LAN, starting from several blocks of buildings to entire cities.

MANs also can depend upon communications channels of moderate-to-high data rates.

A MAN (Metropolitan Area Network) could be owned and operated by single organization, but it always are going to be employed by many individuals and organizations.

MANs may additionally be owned and operated as public utilities. They will often provide means for interworking of Local networks.

Metropolitan Networks (MANs) can span up to 50km, devices used are modem and wire/cable.

Metropolitan Network links between LANs are built without cables using either microwave, radio, or infra-red laser links.

DODB, Distributed Queue Dual Bus, is the Metropolitan Area Network standard for data communication. It is specified in the IEEE 802.6 standard. Using DQDB, networks can be up to 30 miles long and operate at speeds f 34 to 155 M bit/s.

WAN (Wide Area Network)

What Wide Area Network: A Wide Area Network (WAN) connects different LANs (Local Network) over great distances. The connection between LANs is usually a dial-up connection or a leased line from a national telephone carrier.

A Wide Area Network provides long-distance transmission of knowledge, voice, image, and video information over an outsized geographic area which will comprises a rustic , a continent or maybe the entire world.

WAN (WIDE AREA NETWORK)

Wide Area Network (WAN) may be a network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries).Or, less formally, a network that uses routers and public communications links.

In contrast to Local Area Network (Which depends on their own hardware for transmission), WANs (Wide Network of Area) may utilize public, leased, or private communication devices, usually in communication and may therefore span an enormous number of miles.

A WAN that's wholly owned and employed by one company is usually mentioned as an enterprise network. The largest and most well-known example of a WAN is that the Internet.
WANs are accustomed connect LANs and different kinds of networks together, so as that users and computers in one location can communicate with users and computers in other locations.

Many WANs (Wide Area Network) are built for one particular organization and are private. Others, built by Internet Service Providers, provide connections from an organization’s LAN to the web.

WANs (Wide Network of Area) are often built using leased lines. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the opposite. Leased lines are often very expensive.  Instead of using leased lines, WANs also can be built using less expensive circuit switching or packet switching methods.

Network protocols including TCP/IP deliver transport and addressing functions. Protocols including Packet over SONET/SDH, MPLS, ATM and FRAME relay are often employed by service providers to deliver the links that are utilized in WANs, X.25 was a crucial early WAN (Wide Area Network) protocol, and is often considered to be the “grandfather” of Frame Relay as many of the underlying protocols and functions of X.25 are still in use today (With upgrades) by Frame Relay.

Performance improvements are sometimes delivered via WAFS or WAN (Wide Area Network) Optimization.

There are two types of Wide Area Network (WANs)

• Switched WAN that connects the end systems, which usually comprise a router that connects to the LAN or WAN.
• Point to Point WAN (Network of Wide Area) is normally a line leased from telephone or cable TV provider that connects a home computer or a small Local Area Network to the internet service provider. 
• This type of WAN is usually wont to provide internet access.

Characteristics of WAN (Wide Area Network)

• Covers a long distance (More than 1 Kilometer)
• Usually spans several locations (even world wide)
• Usually features a larger number of users (100’s or maybe 1000’s)
• Implemented as a client-server model

Inter-Network

What is Inter-Network: A collection of interconnected networks is called an inter-network or internet. These terms are going to be utilized in a generic sense, in contrast to the worldwide Internet, which we'll always capitalize.

When two or more networks  are connected, then it become Internetwork or internet. Individual networks are joined into Internetworks by the utilization of internetworking devices (such as routers, gateways etc.)

The term internet (lowercase I) shouldn't be confused with the web (uppercase I). The primary could also be a generic term used to mean an interconnection of networks. The second is that the name of a selected worldwide network.

Many networks exist within the world, often with different hardware and software. People connected to at least one network often want to speak with people attached to a special one. 

The fulfillment of this desire connected, sometimes by, means of machines called gateways to create the connection and provide the desired translation, both in terms of hardware and software.
A common sort of internet may be a collection of LANs connected by a WAN (Wide Area Network).

An internetwork is made when distinct networks are interconnected an internetwork, but there's little agreement within the industry over terminology during this area.

One rule of thumb is that if different organizations paid to construct different parts of the network and every maintains its part, we've internetwork instead of one network. Also, if the underlying technology is different in several parts (e.g., broadcast versus point-to-point), we probably have two networks.

My view about this post (conclusion)

This post shows the types of networks. The Characteristics of those network types are also in this post. It also shows the type within the types. The four types of network are well-known to the user. If you want to read the network topology is also on this site. The history of what a network is also shown in detail on this site. If you want to know this then go to search box and type network topology and what is network, history it will come up.
