ADVANTAGES OF NETWORKS
v
Flexible Access: Network allows users to access
their files from different computer within the network and also users can work cooperatively through the network.
v
Data/File sharing: A network gives more
flexibility in file sharing than using external storage devices (e.g. diskette).
It provides a very rapid method for sharing and transferring of files.
v
Security: A network usually ensures data
security within the network. Files and programs on a network can be designated
as inhibit copy so that there would be no worry about illegal copying of program.
Password can also be established for specific directories to restrict access to
unauthorized users.
v
Resources Sharing: it is easy to setup the entire
computer in network to share a hardware resource such as a printer. Resources
sharing are another area in which a network is better than standalone computer because
user will not need to be bouncing from one system to another before printing or
scanning.
v
Collaboration/Communication: A network allows employees to
shares files, view other people's work and exchange of ideas more efficiently. E-mail
and instant messaging tools can be used to communicate quickly and to store
message for future references especially in a larger organization.
v
Error Reduction and Improve Consistency: one can reduce errors and
improve consistency by having all staff work from a single source of
information, so that standard versions of manuals and directories can be made available,
and data can be backed up from a single point on a scheduled basis, ensuring
consistency.
v
Increased Productivity: Networks increase productivity
as several people can enter data at the same time, but they can also evaluate
and process the shared data. So, one person can handle accounts receivable, and
someone else processes the profit and loss statement.
DISADVANTAGES OF COMPUTER
NETWORK
v
Network Management Problem: If a network developed problem,
it requires the knowledge of an expertise. A careful attention in attempting to
solve the problem may lead to tome wastage and also cost of maintenance is
high.
v
Servers Fault: Since the server is the heart
of the network, once it develops a fault, the available application will also
be stopped such as loss of access to necessary programs and files. When a
computer on the network is affected by a virus, the other will also be
affected.
v
Expensive to Install: The initial costs of
installation may be high because cables, NIC and software are expensive and the
installation may be required the service of a technician.
v
Privacy: Due to the access of programs
and files on the network, different users will have access to other without
their permission.
