A network controller called a computer network administrator is in charge of configuring servers, client computers, and data protection protocols. System managers are another name for them. Additionally, they guarantee that these parts will operate correctly. The manager is responsible for routinely maintaining the company's confidential IT system. Administrators keep an eye out for any infractions of company policy and legal requirements in order to boost output.

Almost every business that uses a variety of hardware or software tools needs a system administrator to keep track of all the complex systems. Employing administrators to manage all of a company's servers, networking, and IT equipment is standard practise. Businesses view these people as being essential parts of the telco or IT organisation. Installation is necessary for firewalls, email servers, client operating systems, and the internet; each of these can be improved or customised.

Due to the rapid expansion of the IT and telco industries, administrators frequently adhere to the standards stated in an organization's policies. The administrator is an essential part of the IT staff and guarantees business continuity.

For instance, if there is an issue while a network or the internet is being used by many users simultaneously, it needs to be fixed right away. Employers are in great need of administrators who can do this. Delays have a significant effect on common corporate processes because of the possibility of financial loss.
