Who is a network administrator?

No self-respecting company has long been complete without computers and its own local network. The professionals who provide her work hold a lot in the life of the company. One such professional is a network administrator. This is a person who is responsible for ensuring that the computer network of the enterprise functions in a normal mode.

Tasks and Professional Responsibilities

Configuring equipment and a computer network, ensuring its continued operability and operational safety, eliminating emerging problems, setting up access to network resources for each user - this is what this work consists of. The system administrator performs the following duties:

- installation of network equipment, its configuration and maintenance of its working condition;

- installation on servers and computers of operating systems and necessary programs;

- monitoring the operation of the network and equipment, warning and troubleshooting;

- issuing network addresses to network devices and computers included in it;

- selection of network protocols and their configuration;

- user registration and access control to network resources;

- technical and software user support, consulting, drawing up instructions;

- creating backup copies of data;

- ensuring information security and virus protection.

In some cases, these tasks are supplemented by care about network services, installation and support of file servers, VPN gateways, and so on, as well as maintenance and repair of computers and office equipment.

Creating and maintaining a local network of the company is the main task that the system administrator solves. Work with hardware and software, server maintenance and thinking through information security policies are also part of his daily routine.

Education and work experience

A future network administrator must necessarily have a higher technical (profile) education, preferably in the field of information technology, computer systems or applied informatics. As elsewhere, a great plus for the applicant for this vacancy is experience in the specialty.

Necessary character traits

In the course of its activities, the network administrator finds and fixes a variety of problems. Therefore, he must be not only educated and competent in his field, but also calm and patient. He also needs to be able to quickly move from one task to another, instantly concentrate and find creative solutions to emerging problems. However, he, like any employee in general, has to cope with a large amount of rather monotonous daily duties, for which ordinary perseverance is required.

A network administrator can work not only in a company specializing directly in high technology, but in any company that has a local network. He reports to the head of the department.
