Benefits of a Wireless Network

A softmodem soft ware modem is a modem with minimal hardware that uses software running on the host computer, and the computer's resources especially the central processing unit , random access memory , and sometimes audio processing , in place of the hardware in a conventional modem. Consumer-grade "softmodems" are mostly called winmodems because they have been known to originate working only on IBM PC compatible computers with drivers only available for one or more Microsoft Windows operating systems. The exact same concept was known to exist with other classes of hardware in the s, such as "win- sound cards " and "win- network cards ". Softmodems cost less to manufacture than conventional modems because they had less hardware. However, they shared the computer's limited resources with other tasks , which reduced the resources available to, and sometimes the performance of, the computer's primary tasks. This was very apparent in the typical case of connections suddenly dropping when the Microsoft Windows screen saver activated.
