What does a system administrator do?

This profession is a technical specialty, as it includes responsibilities such as installing software on users' personal computers, setting up various equipment, and upgrading the network. Also, the duties of the system administrator include monitoring employees, providing access for certain categories of users, providing access to the local network, and much more.

However, there are certain network administration problems. In his work, the system administrator may encounter tasks such as determining the reason for the failure or error, the quality distribution of resources, improving the efficiency of users, improving processes for making various decisions. It also happens that a specialist is faced with a situation where the user is not able to explain the problem. That is why the system administrator must have the appropriate qualifications.

A fairly important component is the characteristics of the system administrator. You need to understand that the system administrator, throughout his work, is faced with many problems that need to be fixed and resolved clearly, professionally and efficiently. That is why the main personal characteristics include the ability to concentrate, the ability to perform several tasks at the same time, have leadership qualities, and be able to change the direction of the prepared plan radically in the process of work. Given all of the above, it is not surprising that the salary of the system administrator is quite high. Moreover, depending on the region, the level of salary differs slightly.

The main functions of network administration are a kind of management, but it concerns not people, but computers. And in order for the fulfillment of the tasks set to be carried out efficiently, software developers have come up with various utilities and programs that have special tools for performing the above functions.

It is important to understand who the network administrator is. A network administrator jobs is a person who works in a company that has local area networks, as well as a computer park. Such a specialist should have higher education in the appropriate direction, as well as regularly take advanced training courses. Otherwise, even the most experienced specialist will not be able to solve the tasks that a new employer will set for him or will face technical difficulties in resolving certain issues. On the network you can find a sample resume of the system administrator, which is quite easy to fill out. But at the same time, it is necessary to remember that each person has individual qualities, knowledge and experience, therefore it is better to prepare well before interviewing for a new job and move away from standard resumes, Having clearly described your own advantages as a specialist. Each company may have its own requirements for a system administrator. Therefore, you must first negotiate with the employer a list of duties and functions assigned to the specialist. Otherwise, the new employee will not cope with the tasks or will work too slowly.

Network administration is a work that in a sense is creative and versatile, but the technical side of the issue is the basis of network administration. Therefore, it is very important to understand how computer networks work. No matter what type of computer network they are, they have a number of specific components that remain unchanged. First of all, these are network equipment, communication tools, software, cable systems, network services, as well as various network protocols. Despite the fact that all devices have a very complex system, they closely interact with each other, so the system administrator must be able to understand each of them.

What tasks is network administration responsible for? This includes network planning, network equipment setup, network service setup, troubleshooting and troubleshooting, installation, network protocol setup, traffic monitoring, various network nodes, sensitive data is also protected, and backups are made. Additionally, a number of other tasks can be performed, which are also pre-negotiated with the employer.

There is a certain classification of computer networks. All of them are divided into categories of networks: local, global and city. Local allows multiple users to work simultaneously. Global networks provide an opportunity to work for users who are at a considerable distance from each other. City networks are not so large, but at the same time they are able to transmit information over short distances at a fairly high speed.

Computer Network Development Criteria

There are certain criteria for designing a computer network. First of all, this is the purpose of the network, type of system, number of computers, software, security policy. Next, a procedure is developed so that the network is built competently and works effectively for the next years.

Security tools are administered in several ways. This is the dissemination of information that is necessary for the subsequent operation of security equipment, as well as the collection and analysis of information on the operation of security equipment. Generation, distribution of keys is carried out, access to information is configured, encryption is managed, etc.

In addition, there are certain utilities for remote network maintenance. Thanks to such utilities, you can perform remote network administration. Among them, the most popular are Windows Remote Desktop, Apple Remote Desktop, as well as UltraVNC and Remote Office Manager. Such programs for remote administration allow you to perform many tasks that are assigned by the company's management to the system administrator. The evolution of administration concepts shows that in recent years the emphasis has not been shifted to individual resources, but to the complete satisfaction of various user requests. Moreover, the development of the concept concerns not only architecture in systems. Now integration is aimed at network and system management, which has increased the importance of system administration.
