Network Computers

THE    INTERNET  LINKS  MILLIONS  of  computers  world  wide , and anybody  with  a  personal  computer (pc)  and  basics  communication  tools can  become  part   of  it .The  ever-expanding  Net  is  becoming  a  vital   resource for  business  ,education  ,and  entertainment .The   huge  multimedia  database  of  the  world  wide web , which  is  one  aspect  of  the  Net ,is  so  sophisticated  that  user  can  "meet" in  virtual  worlds".As   the  net evolves  , so  new  ways  of  computing are  made possible .Network  computing is  one  possible  development  which  promises    greater  compatibility  and  efficiency  than  personal  computing,At  present the  Net   consist mainly  of  PCs  with  large  amount    of  processing  power  and disk  space (called 'fat  client computers") connected   to  servers (other computers  that distribute  data  ) The idea  behind   network  computing   is  to  replace  the  PC. or  fat  client ,with  a  network  computer.(NC).or thin  client.A thin  client  computer  has  a  processor  , like  PC, but less  memory. and  no  disk  storage, and so  is  much  cheaper .Instead  of  storing  application ,programs ,and  data  on  a  hard  disk (as  a pc  does).,an  NC   simply   downloads programs  and  data  from  a  server into  its  RAM. as needed.Network  computing  promises  economies  of  scale and centralization  ,since  all  the  data is   stored   on  a  few  server ,and  any   software, developments that need to  be  made  apply  to  these   servers  only .To  be   continued .
