Network Administration Jobs

Any organization with an online presence wants to ensure that this presence is seamless, and that users and customers can constantly access their website for information, or to purchase goods and services. A network administrator ensures that this technical support is solid, and works to quickly resolve any potential issues within the network, to make sure that all systems are a go when it comes to the organization.


This often includes testing the network for weaknesses, which could lead to resolving more deep-seeded technical issues that could have been lethal to the company’s growth. It also includes utilizing specific e-mail and internet filters to protect the organization from outside threats of all kinds, and ensuring that the company’s network is updated in every sense possible.

 

A network administrator’s role can be very different, depending on the organization, but almost always requires a diligent eye and a pro-active attitude when it comes to protecting the security and productivity of a company or organization. The position requires a tremendous amount of technical knowledge, and without network administrators, organizations would be susceptible to more attacks, and have much less network resilience, which is essential in terms of overall productivity.

    Hello, Source code of the project will be our property. We want you to design and develop a software for us. Which can create our one machine as master machine. And remaining other machines will be user machines. Whatever command we will be giving on master machine, same command should be followed by user machines at same time. Suppose, there is any sale to be started at a particular time on any marketplace for few seconds, we want that same process to be executed on master machine and followed by user machines at the same time. There should be different static IP on all the machines during execution and different ip should go to admin. Otherwise Admin may detect it and block it. There should be different VPNs on all the machines.
