                  phone  with facility provided  by  a general

                  operating system software providing a

                  organization.  Cost, Size  and performance of
                  such computers are very high. These Computers  XúmVm ng©Zc H$åß`yQ>a go A{YH$ hmoVr h¢Ÿ& BZH$mo EH$
                  cannot be  handled or  purchased by  a single  ì`{º$ Z Vmo IarX gH$Vm h¡ Am¡a Z hr Mcm gH$Vm h¡Ÿ& ¶o
                  person. They  have  a big  role to play  in the  Am°J}ZmBOoeZ ‘| EH$ ~‹S>r ^y{‘H$m {Z^mVo h¢& BÝ\$m°_}eZ
                  organisation. In todays  age of Information

                  highly dependent on the performance of such  Eogo H$åß`yQ>am| na {Z^©a H$aVr h¡Ÿ& Hw$N> g§ñWmJV H$åß`yQ>a
                  Computer System. Some important  organi-    Bg àH$ma h¢:

                      Network Servers are specialized computers   `o H$åß`yQ>a EH$ H$åß`yQ>a ZoQ>dH©$ H$m à~§YZ H$aZo Ho$

                  computers run a network management software
