Who is the network administrator?

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

Tasks and professional duties

Setting up equipment and a computer network, ensuring its permanent operability and security of operation, eliminating emerging problems, configuring 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 operational status;

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

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

- delivery of network addresses to network devices and computers included in it;

- selection of network protocols and their configuration;

- registration of users and control of access to network resources;

- technical and software support of users, consulting, drafting instructions;

- creation of backup copies of data;

- providing information security and protection against viruses.

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

Creation and support of the company's LAN is the main task that the system administrator decides. Working with hardware and software, maintaining the server and thinking through the information security policy are also part of its daily business.

Education and work experience

The future network administrator must necessarily have a higher technical (profile) education, preferably in the field of information technology, computer systems or applied informatics. As well as everywhere, the big plus for the applicant for this vacancy is work experience in the specialty.
Necessary properties of character

In the process of its activity, the network administrator finds and eliminates 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 worker in general, has to cope with a large volume of rather monotonous daily duties, for which you need ordinary perseverance.

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