A Wide Area Network is the one that covers large areas. And when we talk about large areas we mean beyond the metropolitan, regional and the even the national boundaries. If we talk in simple language WAN basically connects two or more LAN by the use of devices which are either routers or act like routers. The users at the different at the location of Wide Area Network are connected by a common server. It is called as a server as it will indeed serve the different people, institutions or business groups all together.
With the use of the central database system all the computers that are connected to this WAN can save the data in real time and thereafter send input results to the central server in order to receive the output results at the same time.
Implementation of WAN
The Wide Area Network can be implemented by use of a couple of switches and routers that are inter-related in order to structure the Wide Area Network. The switches can be attached in vast areas or diverse locations like complete areas or partial networks. A wide area network can be confidently possessed or hired from a service provider. The fact about WAN that is undeniable is that it is capable of covering multiple locations.
The leased line out of all these is the most classic type of WAN connection option where there is point to point connection between two computers. This is largely used by small colleges or schools. The Circuit switching is another type of WAN. In this type of WAN, a circuit is created between the end points. One phenomenal example of this is Dial up connection. Another feature of broad network is the packet switching connection where multiple sets of data is sent and received simultaneously.
The Wide Area Network has made the communication procedure diagonally easier. The distance between the people has been reduced marginally. This has been possible by the introduction of Virtual Private network where the employees can take their work home and even store and share this work online.
Precautions while implementing Wide Area Network
When you’re implementing Wide Area Network and you begin with its usage in the company, group or business organization then there are certain precautions that you must be careful about. However, these problems or challenges too might be overcome by the use of latest technology. On WAN the key problem is of security. When you get connected on the internet by use of Live IPs, anyone can intrude into your server and hack your privacy. To manage this firewalls and router securities can be used. However, implementation of this is a costly affair. The latency period of WAN is high, but this can also be catered by taking high speed internet connections.
WAN is an extremely essential tool and must be implemented in the workstations of all the companies or business organizations. But be careful about the precautions that have been mentioned above.
