Computer software is no longer a major barrier to wide use of wireless information systems

A computer is a device that accepts information in the form of digitalized data and manipulates it for some result based on a program or sequence of instructionson how the data is to be processed . Modern computers inherently follow the ideas of the stored program laid out by John Von Neumann in 1945 . Essentially , the program is read by the computer one instruction at a time , an operation is performed and the computer then reads in the next instruction . Nowadays , computers are devised in order to allow multiple programs to work on the same problem at the same time. WLANs are here to stays as they provide flexibility and mobility which makes effective extensions and attractive alternatives to wired Networks.

They are also cost effective by reducing the direct costs of cabling and labor associated, and also helps in reducing the indirect costs of user downtime and admin overheads. Wireless networks are the wave of the Internet future. Wireless networks utilize the information capacity of the Internet along with other capabilities such as sharing wireless resources like printers. Wireless networks utilize the air all around us to send information to and from users without having to connect cables. Wireless Local Area Network technologies allow us to finally connect multiple users to share Internet connections without messy and expensive cable installation procedures Computers in the workplace became a national level project in 1988 . The increasing use of computers helps to facilitate complex works but skilled or well- trained human workers are required . Due to modern technology such as nano technology , a quantum computer could solve problems in a few days that would take men millions of years . In ...
