System Administrator
A system administrator is a professional who is held accountable for network setup, annual server maintenance such as mail servers and file servers, and much more. Based upon an organization’s requirements and other IT-related infrastructure, a system administrator is tasked with providing a reliable work environment, particularly whereby multi-user computers are associated with the LAN network.

System Administrator requirements include an in-depth understanding of computer software, hardware, and networks. The IT System Administrator has to design, organize, modify and support the organization’s computer systems. These professionals have to upgrade and manage the software and hardware. The IT System Administrator should handle any issues related to Local Area Networks (LAN), Wide Area Networks, and Network segments. It is the System Administrator who maintains operating systems, business applications, security tools, web-servers, email, laptop, and desktop PCs.

In an organization, every task that is performed by the system administrator requires an uninterrupted internet connection, which is maintained by the system administrator. For example, the successful sending and receiving of work emails happen only when mail servers are working fine. Similarly, the file server is a hub for saving and managing the data and, it supports the data usage by other computers that are using the same network.
