Planning and Managing IT Infrastructure
Notes Computer networks allow the user to access remote programs and remote databases either of
the same organisation or from other enterprises or public sources. Computer networks provide
communication possibilities faster than other facilities. Because of these optimal information
and communication possibilities, computer networks may increase the organisational learning
rate, which many authors declare as the only fundamental advantage in competition.
Besides this major reason why any organisation should not fail to have a computer network,
there are other reasons as well:
cost reduction by sharing hard- and software resources
high reliability by having multiple sources of supply
cost reduction by downsizing to microcomputer-based networks instead of using
mainframes
greater flexibility because of possibility to connect devices from various vendors.
Because of the importance of this technology, decisions of purchase, structure, and operation of
computer networks cannot be left to technical staff. Management as well has a critical need for
understanding the technology of computer networks.
Network IT includes information systems that improve communications and support
collaboration among a members of a workgroup.
Example: Wikipedia, Web Conferencing, Electronic corporate directories.
In case of the Network IT all the services are provided with the help of web only.
Example: In this case, one can directly contact other by using web services like video
conferencing and many more.
!
Caution Only with the help of computer networks can a borderless communication and
information environment be built.
