Meaning of WAN?

WAN is a collection of computers, which are inter connected via Network over a geographic area. WAN is often connected through the Internet or it can also be connected by contracts with Internet service providers. There are three types of network LAN, MAN and WAN. WAN differs from a MAN because WAN networks covers a distance compared to MAN. One network of WAN can cover minimum of up to 1500 miles away or even more.

All Types of Network definitions

• LAN – local Area Network
• WLAN – Wireless Local Area Network
• SAN - This can be called in several terms such as System Area Network, Server Area Network, Small Area Network or Storage Area Network
• CAN – There are many Abbreviations for CAN such as Controller Area Network, Cluster Area Network and Campus Area Network.
• WAN – Wide Area Network
• MAN – Metropolitan Area Network
• PAN – Personal Area Network
• DAN – Desktop Area Network

If you take Networking History and evolution actual networks are only LAN AND WAN. These other networks have emerged slowly when the technology develops in networks.

High Level Networking Design Types

There are two classification of High level networking they are called as Client-server and Peer to Peer Networking.

About Client Server Network Many types of client server Network are there but the basic definition of “Client server" it's a network architecture which divide a client( a request from an application using graphic user interface) from a server. Each time a client software sends request to server and the server process it and send back the desired request of a client. Important types of Client Server Networks are web servers, file servers, application servers etc. Some of the client server applications are FTP, Email clients and web browsers.

About Peer to Peer Networking

A computer network depends heavily on the power of Internet, bandwidth this network is relatively consist of low number of servers. P2p network are normally deployed on the connection of Nodes largely called as ad hoc connection.

Advantage of Peer-to-Peer Network.

If you talk about advantages P2p has many including that the distributive nature of P2P helps increase the flexibility in case of failures by redoing data over multiple peers in correct and perfect p2p systems we can enable peers to search for the data without relaying on the server. In latter case obviously there is no failure in this system.
