Network administrators are responsible for the upkeep of computer hardware and software systems. They usually focus on the network components within their company. In some cases it is the responsibility of network administrators to design and implement new networks. Although some of the responsibilities for network administrators may vary depending on the size and locations of the company they work for, there are still some common responsibilities that all administrators will share. They are generally in charge of network address assignments, management and implementation of protocols. They also handle the maintenance of networks and file servers. When working for smaller companies, network administrators are also usually in charge of conducting maintenance on computers, printer, routers, smartphones, etc. Their duties include network monitoring, testing for weaknesses, handling updates, installing and implementing security programs, and evaluating network management software. Network administrators are also responsible for ensuring that the network used by the organization is working effectively and is properly maintained. Administrators who work for smaller companies also have the responsibility of making sure that licenses are paid for and up to date, checking for security breaches, and maintaining proper installations and applications. In order to become a network administrator it is important to have extensive technical knowledge. It is also important to have a bachelor’s degree in computer science, information systems, mathematics, or another related field. Working as a network administrator can be stimulating and exciting for those with an interest in technology and computer networks.

Systems administrators are essential to the operation of most businesses. The system administrator is tasked with creating computer systems as well as maintaining them, troubleshooting them for co-workers, and documenting their systems. Becoming a systems administrator is a challenging profession. There is no degree that one can earn to become a systems administrator. Having a bachelor's degree in computer science or computer engineering will help, but systems administrators will primarily need to be self-taught.
 
A systems administrator is behind the scenes for all technological setups at the workplace. Their designs and implementations are necessary to maintain workflow and, for many, to perform their most basic duties. There is no end to a systems administrator's education. Due to the ever-changing and expanding nature of technology, a systems administrator must constantly learn about the new software and hardware that becomes available. It is the task of systems administrators to determine what available technologies can be applied to their business. Systems administrators will run into one persistent issue: what they need does not always exist yet. For this reason, a systems administrator will need to be able to create, configure, and maintain software and hardware that is specialized for their business. Not every task will be from the ground up, though, and many tasks will be just to upgrade existing software and hardware; this means upgrading current infrastructure and deploying new applications as necessary.
 
Thanks to their never-ending education in all things related to computers, systems administrators will be an invaluable source of knowledge for their company. They will end up making recommendations for most software and hardware upgrades. They will also need to interact with co-workers to find out what is wrong so that they can provide support and maintenance to the system and its operations. This often involves troubleshooting individual computer issues as they arise.
