LOCAL LITERATURE
In the old days, business was done
using papers and flat registers. The organization of these registers was
difficult and the storage of huge amounts of data was a real problem. Also, the
process of preparing a report takes a lot of time. But when computers were
introduced into the business field, everything had changed. Databases were used
to store huge amounts of data and organize them. Instead of spending many hours
(or maybe days) preparing a report, a query consisting of a number of
statements can perform the job in some seconds.
Although databases were very useful,
another problem has appeared. Companies and corporations spread over wide
distances. A single company can have branches in all the governorates of a
country and maybe with some branches outside that country. Data communicating
and sharing was a problem. This problem was solved using computer networks
which are the best way for data communicating. Nowadays, computer networks are
essential for any business. Computer networks are used for file transfer, voice
and video conferencing. For this reason, we have chosen our final project to
discuss networks from different sides.[1]
