System Administrator is a specialist in servicing computers and local computer networks. The profession is suitable for those who are interested in computer science (see choosing a profession based on interest in school subjects).

Description of the profession

IN large companies, for which the uninterrupted functioning of information systems is vital (telecommunications companies, publishing houses, etc.), there are special IT departments (or departments information technologies), in which system administrators work for permanent basis. Smaller organizations, as a rule, prefer to invite these specialists only in case of any problems with computers or local network, i.e. work with freelancers. Nowadays, many office buildings have computer services that report to the property owners. Employees of tenant companies contact these services to troubleshoot problems with computers or the local network.

First of all, the system administrator's responsibilities include setting up the software. It installs and configures operating system(Windows, Novell or Unix), programs necessary for the operation of the company (office, graphics, accounting, etc.), monitors software updates. If necessary, the system administrator explains to employees how to use the programs and troubleshoots problems caused by their unqualified use.

The system administrator is also responsible for the equipment. Firstly, he is directly involved in the preparation of the purchase order computer components. Secondly, it assembles computers, monitors their operation, and, if necessary, repairs or replaces them.

An important part of a system administrator's job is establishing communication systems. It connects computers into a network by laying cables, optimizes the operation of servers, and configures the Internet and email. In addition, the system administrator organizes the work of databases and maintains office PBXs.

To preserve trade secrets, the system administrator processes computer information in a certain way. To prevent the loss of data valuable to the company, it stores backup copies.

Another task of this specialist is to combat spam arriving via e-mail. (Special programs are used for such protection.)

A system administrator can also engage in other tasks, in particular, writing and editing web pages. Many system administrators are self-taught. However, for a good job it is desirable to have a higher technical education with a specialization in management information systems. In large companies, employers may require special certificates indicating the qualifications of a system administrator. The most famous certification system is considered Microsoft system Certified System Engineer.

A professional system administrator must have a thorough understanding of computer hardware, network equipment and software issues. He constantly monitors the development of computer technology and applies new technologies in practice.

Hello friends! Today we’ll talk about such a profession as a system administrator. Since our century is a century technical progress. The Machine Age. It is impossible to imagine even the most seedy company without a computer! The director of the enterprise, in the accounting department, in the offices of department heads, and even ordinary employees - everyone has computers at their workplaces.

Corporate mail, news, market, bank - all these benefits of the modern workforce undoubtedly help to survive in the cruel world of business. But how do you make it all work together? How to make sure that employees are not “in contact” and “classmates” sitting in work time, but were you busy? How to protect secret information from your work computer from hackers? This is why such a profession as sysadmin exists.

If you ask Google who he is, he will answer something like this:

System administrator is an employee whose job responsibilities involve ensuring the normal operation of the fleet of computer equipment, networks and software, as well as ensuring information security in the organization.

Popularly, such a specialist is simply called “administrator” or “sysadmin”.

So let's figure it out...

What is he doing

The responsibilities of the system administrator include ensuring the stable operation of computer equipment.

This stage includes:

1. installation and configuration (and sometimes even purchase) of computers,
2. components and peripheral devices(printers, scanners, etc.)

When doing this, the main thing is to lay out computer communications so that even the most sophisticated worker does not pull out the plug with his foot and spill the coffee. system unit.

The most difficult part of the job is to explain to the boss’s beautiful blonde secretary that there is no need to pin the mouse wire with the buttons to the table, even if it gets in the way)))

• Setting up programs and ensuring their stable, reliable operation will be, perhaps, the most labor-intensive part of the job. The software can be completely different, depending on the specifics of the enterprise. For example, from the usual Microsoft word & excel, to the ORACLE DBMS and accounting programs.

The main problem in the operation of software is, unfortunately, the human factor, since usually employees’ complaints to the system administrator begin with the words: “I pressed the wrong button and everything suddenly disappeared somewhere.” Synchronizing the work of programs and setting up the correct protection “from fools” is, consider, half the work of a system administrator.

• The system administrator must also know and be able to correctly configure access parameters so that each employee can turn on only his computer, his profile, and launch only those programs to which he has access according to his status in the campaign. If the employees’ work is connected to the Internet, then the system administrator will have to configure access parameters in world wide web so that neither “in contact” nor “oddnoklassniki”, so beloved by office workers, are accessible from work computers.

A system administrator is a very significant figure in a company, like a knight on a chessboard. It seems like he’s not the most important person, but it’s absolutely impossible to live without him. Sometimes it is enough to complete admin courses to become the master of office computers. But computers tend to break down, both for an ordinary employee and for the general director.

You can learn more about what a sysadmin does by watching the video.

Pros of the profession

The incomparable advantages of the work include almost complete independence, because finding a person at the company who will understand computers at the level of a system administrator and will check your work is almost impossible. It is the system administrator who is the “virtual director” in the campaign, therefore, having correctly configured the equipment and given valuable instructions to the “office plankton”, you can safely spend the drab work days, indulging in social networks or the online games that absorb modern youth. In addition, solving problems with technology of superiors and senior management (top manager, chief accountant, personnel officers, etc.) will provide good connections and help in career advancement.

Representatives of this profession, again, have an order of magnitude less paperwork than other workers. As practice shows, while at the end of the month or year, department heads and subordinates are intensively writing reports, settling accounts and summing up results, system administrators are spinning twisted-pair soldiers in their offices.

The obvious advantages include the salary of system administrators. According to the website “job.ru”, companies are willing to pay an average of $1,200 to $3,000 for services of this kind.

The disadvantages (cons) of the profession include:

1. Uneven and sometimes high workload. Through the efforts of careless users, computers glitch and break down with enviable regularity in almost any enterprise.
2. Lack of understanding and sometimes absolute unwillingness to understand at all how the system works. The mouse is buggy - the system administrator is to blame. The site does not work - the system administrator is to blame. The power supply has burned out - the system administrator is to blame. And go and prove that the voltage in the electrical network does not depend on you!
3. Limited opportunities for career advancement. If the company’s activities are not related to the provision of services in the field of information technology, then there is nothing more to count on except for an increase in salary.

Characteristic

What qualities do a good system administrator need?

• Firstly, he must have a good technical education. Knowing what is a system unit, what is a monitor, and how to reinstall the operating system will clearly not be enough.
• Secondly, a good sysadmin must know English language at a level clearly superior to the basic one.

Most programs and especially technical description they are supplied in English and gaps in language knowledge can be expensive, and in a reputable company there is nothing to do without knowledge of a foreign language.

• And, finally, thirdly, communication skills and the ability to find an approach to work colleagues will provide the system administrator with not only additional cookies for coffee, but sometimes also a good bonus.

If you are used to working independently, speak good English and know how to approach people, this job is for you. Yes and wage will allow you to provide not only for yourself, but also to please your family, and in our information society a person with this kind of profession will never be left without work.
