A System Administrator, also known as a System Administrator (SA), is a specialized person who is primarily responsible for the smooth functioning, maintenance, configuration and safe operation of large multi-user networks, including the servers themselves. System administrators are also responsible for managing and troubleshooting the entire network and are usually responsible for managing the users of the server. In the most basic definition, a system administrator can be defined as someone who manages a complex piece of software that includes all of its functions. A system administrator also has a responsibility to maintain and update all versions of the software, as well as its user interface and security features. System administrators must be proficient with both programming languages, such as Windows or Linux, as well as command lines, which can be utilized by their staff, in order to perform their administrative tasks.
The most important function of a system administrator is to provide the proper support for various systems of the network. This support may include maintaining hardware resources, as well as supporting and repairing software. System administrators, also known as network support staff (NSS), can either be in-house (for larger organizations) or hired out. Hired out systems are usually contracted by organizations that do not have the budget or manpower to maintain their own system. However, it should be noted that if an organization or corporation does hire a system administrator they are usually paid more than in-house systems, due to the extra level of skill, knowledge and responsibility required to run a highly complex network.
In addition to being a specialist in the technical aspects of the network, System Administrators must also have good communication skills and knowledge about the many applications and scripts that run on a server. They must also possess experience with several different systems that are used in the server, such as email and file sharing services. In addition, System Administrators must have a thorough understanding of Microsoft Windows as well as the Microsoft Exchange server. System Administrators are highly skilled individuals that can make a huge difference in the productivity and effectiveness of a company or business, when managing its computer network.
