lan, man aur wan ki visheshtaye
Answers
Local Area Network (LAN) की विशेषताएं
- छोटे geographical Area में इसकी दुरी सिमित है।
- एक घर, Office और college में इस्तेमाल होता है।
- इसकी ownwrship private होती है।
- आसानी से इस Network को बनाया जा सकता है।
- इस Network की data transmission speed high है।
Metropolitan Area Network(MAN) की विशेषताएं
- बड़े geographical Area में इसकी दुरी सिमित है जैसे town, city।
- इसकी ownership public और private होती है।
- इस नेटवर्क install करने में जादा खर्चा आता है LAN से भी जादा।
- Data transmission speed Moderate है।
Wide Area Network(WAN) की विशेषताएं
- बड़े geographical Area जैसे दो देशों को अपसा में इस नेटवर्क से connect कर सकते हैं।
- इसकी ownership public और private होती है।
- इस नेटवर्क को install और maintenance करना difficult होता है।
- Data transmission speed Slow है।

Explanation:
Features of LAN are following:-
- Every computer has the potential to communicate with any other computers of the network.
- High degree of interconnection between computers.
- Easy physical connection of computers in a network.
- Inexpensive medium of data transmission.
- High data transmission rate.
WAN
WAN stands for wide area network. Wide area implies a long distance, usually from town to town. One-time installation and setup costs, recurring costs, reliability, speed (bits/second), latency, jitter, medium type (fiber, UTP, coaxial cable) and protocols being encapsulated (Ethernet, IP, SDH, SONET, DWDM/dark fiber, etc.) will be considered in your WAN design. Maximum packet or frame size might also be specified in the order. The number and type of quality-of-service (QoS) queues available will vary with each type of connection. Value-add variations, like routing protocol support (i.e. BGP), managed hardware, internet service, voice and video services, usage monitoring, outage penalties, or service level agreements can also be negotiated with your WAN vendor. Extension of the demarcation point to your suite or telephone room or to your router or switch equipment can also be included in the service, if provided by the vendor, otherwise you will be responsible for cabling from your network equipment to the demarc point. The other consideration is redundancy, because if business continuity is important, consider having redundant connections over redundant paths (separate providers, separate infrastructure). Backup links can be made using VPN connections over less expensive internet connections, as well.
MAN
A Metropolitan Area Network (MAN) is one of a number of types of networks .
- .The network size falls intermediate between LANs and WANs. A MAN typically covers an area of between 5 and 50 km diameter. Many MANs cover an area the size of a city, although in some cases MANs may be as small as a group of buildings or as large as the North of Scotland.
- A MAN (like a WAN) is not generally owned by a single organisation. The MAN, its communications links and equipment are generally owned by either a consortium of users or by a single network provider who sells the service to the users. This level of service provided to each user must therefore be negotiated with the MAN operator, and some performance guarantees are normally specified.
- A MAN often acts as a high speed network to allow sharing of regional resources (similar to a large LAN). It is also frequently used to provide a shared connection to other networks using a link to a WAN.
