What is Network? A network is a group of two or more computer systemslinked together Networks are systems that are formed by links. A network can be as simple as two computers connectedby a single cable or as complex as hundreds of computersconnected to devices that control the flow of information. A computer network is a group of computers connectedto each other electronically by which they can talk toeach other and exchange data.
Types of NetworkThere are many types of computer networking which are used worldwide these days.There are some types of network that are usingWorldwide: LAN - Local Area Network WAN - Wide Area Network WLAN - Wireless Local Area Network PAN - Personal Area Network SAN - Storage Area Network GAN - Global Area Network MAN - Metropolitan Area Network CAN - Controller Area Network DAN - Desk Area Network VPN - Virtual Private Network
LAN - Local Area NetworkLAN connects networking devices with in shortspam of area, i.e. small offices, home, internetcafes etc. LAN uses TCP/IP network protocol forcommunication between computers. It is often butnot always implemented as a single IP subnet. SinceLAN is operated in short area so It can be controland administrate by single person or organization.
WAN - Wide Area NetworksAs “word” Wide implies, WAN, wide area networkcover large distance for communication betweencomputers. The Internet it self is the biggestexample of Wide area network, WAN, which iscovering the entire earth. WAN is distributedcollection of geographically LANs. A networkconnecting device router connects LANs to WANs.WAN used network protocols like ATM, X.25, andFrame Relay for long distance connectivity.
WLAN - Wireless Local Area NetworkA LAN, local area networks based on wirelessnetwork technology mostly referred as Wi-Fi. UnlikeLAN, in WLAN no wires are used, but radio signalsare the medium for communication. Wirelessnetwork cards are required to be installed in thesystems for accessing any wireless network around.Mostly wireless cards connect to wireless routers forcommunication among computers or accessing WAN,internet.
PAN - Personal Area Network Personal area networks can be constructed with cables orbe wireless. USB and FireWire technologies often linktogether a wired PAN, while wireless PANs typically useBluetooth or sometimes infrared connections. BluetoothPANs are also sometimes called piconets. Personal area networks generally cover a range of lessthan 10 meters (about 30 feet). PANs can be viewed as aspecial type (or subset) of local area network (LAN) thatsupports one person instead of a group.
SAN - Storage Area Network SAN, system area networks are also known as cluster areanetwork and it connects high performance computers withhigh speed connections in cluster configuration The term SAN can sometimes refer to system areanetworks instead of a storage area network. System areanetworks are clusters of high performance computers usedfor distributed processing applications requiring fast localnetwork performance. Storage area networks, on theother, are designed specifically for data management.
GAN - Global Area Network Global area network (GAN)refers to any network thatis composed of different interconnected computernetworks (WANs) and also covers an unlimitedgeographical area. The most sought-after GAN type is a broadband GAN.The broadband GAN is a global satellite Internetnetwork that uses portable terminals for telephony.The terminals connect laptop computers located inremote areas to broadband Internet.
MAN - Metropolitan Area Networ A metropolitan area network (MAN) is similar to a localarea network (LAN) but spans an entire city or campus.MANs are formed by connecting multiple LANs. Thus, MANsare larger than LANs but smaller than wide area networks(WAN MANs are extremely efficient and provide fastcommunication via high-speed carriers, such as fiber opticcables Distributed Queue Dual Bus (DQDB) is the MAN standardspecified by the Institute Of Electrical And ElectronicsEngineers (IEEE) as IEEE 802.6. Using this standard, a MANextends up to 30-40 km, or 20-25 miles.
CAN - Controller Area NetworkCAN – Campus Area Network Abbreviated CAN, a serial bus network of microcontrollers thatconnects devices, sensors and actuators in a system or sub-system forreal-time control applications. There is no addressing scheme used incontroller area networks, as in the sense of conventional addressing innetworks (such as Ethernet). Rather, messages are broadcast to all thenodes in the network using an identifier unique to the network. A campus area network known as (CAN) is used to inter-connectnetworks in limited geographical locality like university campus,military bases, or organizational campuses etc. It can be taken as themetropolitan network that has the specific settings at the small areajust like a computer lab in the university.
DAN - Desk Area Network DAN is an interconnection of computer devices around the ATM(Asynchronous Transfer Mode). This exchange of information betweenvarious peripherals and CPU is based on the transfer of ATM cellsmainly. DAN enables the network to share resources over the network.It also provides the access to foreign devices. This system enables toform A/V connection. DAN consists of A/V softwares. This softwarehas four main layers. This software is intelligent enough to guide andsupport the A/V devices. It works on a simple process, when we on aVCR. And put a cassette into it, it is automatically connected to themonitor. VCR and other related devices are often connected to thenetwork in order to built DAN.
VPN - Virtual Private Network A VPN is a private network that uses a public network to connect remotesites or users together. The VPN uses "virtual" connections routed through theInternet from the businesss private network to the remote site or employee.By using a VPN, businesses ensure security -- anyone intercepting theencrypted data cant read . A virtual private network (VPN) is a network that uses a publictelecommunication infrastructure, such as the Internet, to provide remoteoffices or individual users with secure access to their organizations network.A virtual private network can be contrasted with an expensive system ofowned or leased lines that can only be used by one organization. The goal of aVPN is to provide the organization with the same capabilities, but at a muchlower cost.
Conclusion In the new era of computer and networking system it can’t beignored that Without network system life becomes so difficult. Again it plays an vital role in the field of modern IT. So we should use it a proper and safe way.
