NETWORKING
A.Introduction
After more than 25 years of establishment and continuous development, the Internet has
outstanding features that no one can deny, from the ability to connect strongly to abundant
information sources as well as a matter of time. and information processing speed. But in
parallel with those advantages, the Internet has contained in it immeasurable dangers.
Therefore, as a person in the network training industry, consulting and designing network
systems for partners. We want to build a completely new, effective and secure network
based on partner requests.
We believe that, with this project, we can help your company manage, use and secure
information well so that the company makes good use of technology and is suitable for the
financial resources of a medium company. and small is on the rise.
