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.
