A Network administrator is responsible for the day-to-day operation of large computer networks.
They organize, install, and support an organization’s computer systems, including local area networks (LANs), wide area networks (WANs), network segments, intranets, and other data communication systems.
What Do Network Administrators Do?
Network administrators may have the following duties:
- Determine an organization’s system needs and install network hardware and software
- Make needed upgrades and repairs to networks and ensure that systems are operating correctly
- Maintain network and computer system security
- Evaluate and optimize network or system performance
- Add users to a network, and assign and update security permissions on the network
- Train users in the proper use of hardware and software
- Interpret and solve problems when a user or an automated monitoring system alerts them that a problem exists
Administrators manage an organization’s servers and desktop and mobile equipment. They ensure that email and data storage networks work properly. They also make sure that employees’ workstations are working efficiently and stay connected to the central computer network. Some administrators manage telecommunication networks.
Administrators may help network architects design and analyze network models.
They also participate in decisions about buying future hardware or software to upgrade their organization’s network. Some administrators provide technical support to computer users, and they also may supervise computer support specialists who help solve users’ problems.
Network and computer systems administrators held about 383,900 jobs in 2018. The largest employers of network and computer systems administrators were as follows:
|Computer systems design and related services||18%|
|Educational services; state, local, and private||10|
|Finance and insurance||10|
|Management of companies and enterprises||7|
Although many network and computer systems administrators are employed by firms in the computer systems design and related services industry, they work in a variety of settings.
Some might administer systems and networks for financial firms, and others work in hospitals or local government offices.
Network and computer systems administrators work with many types of workers, including other IT workers, such as computer support specialists, database administrators, computer network architects, and computer and information systems managers.
Most network and computer systems administrators work full time.
Organizations depend on their computer networks, so administrators may need to work overtime to ensure that the networks are operating properly around the clock.
Most employers require network and computer systems administrators to have a bachelor’s degree in a field related to computer or information science.
Others may require only a postsecondary certificate or an associate’s degree.
Although some employers require only a postsecondary certificate or an associate’s degree, most require a bachelor’s degree in a field related to computer or information science.
There are degree programs that focus on computer network and system administration. However, because administrators work with computer hardware and equipment, a degree in computer engineering or electrical engineering usually is acceptable as well.
Programs in these fields frequently include classes in computer programming, networking, or systems design.
Because network technology is constantly changing, administrators need to keep up with the latest developments.
Many continue to take courses throughout their careers and attend information technology (IT) conferences to keep up with the latest technology. Some businesses require that administrators have a master’s degree.
What Certifications Do I Need to be a Network Administrator?
Companies generally require their network and computer systems administrators to be certified in the products they use.
Certification programs usually are offered directly from vendors or from vendor-neutral certification providers. Certification validates the knowledge and the use of best practices that are required of network and computer systems administrators.
Microsoft and Cisco offer some of the most common certifications.
Network administrators can advance to become computer network architects.
They can also advance to managerial jobs in information technology (IT) departments, such as computer and information systems managers.
Analytical skills. Administrators need to evaluate networks and systems to make sure that they perform reliably and to anticipate new requirements as customers’ needs change.
Communication skills. Administrators must describe problems and their solutions to non-IT workers.
Multitasking skills. Administrators may have to work on many problems and tasks at the same time.
Problem-solving skills. Administrators must quickly resolve problems that arise with computer networks.
The median annual wage for network and computer systems administrators was $82,050 in May 2018.
The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $50,990, and the highest 10 percent earned more than $130,720.
In May 2018, the median annual wages for network and computer systems administrators in the top industries in which they worked were as follows:
|Finance and insurance||87,950|
|Management of companies and enterprises||86,230|
|Computer systems design and related services||85,880|
|Educational services; state, local, and private||71,990|
Most network and computer systems administrators work full time. Organizations depend on their computer networks, so administrators may need to work overtime to ensure that the networks are operating properly around the clock.
Employment of network and computer systems administrators is projected to grow 5 percent from 2018 to 2028, about as fast as the average for all occupations.
Demand for information technology (IT) workers is high and should continue to grow as firms invest in newer, faster technology and mobile networks. Growth also is expected as the use of IT in healthcare increases.
However, an increase in cloud computing could raise the productivity of network administrators, slowing their growth across many industries.
Employment of network administrators in the computer systems design and related services industry is projected to grow 24 percent from 2018 to 2028.
The increasing adoption of cloud services by small and medium-sized businesses that do not have their own dedicated IT departments could increase the demand for network and computer systems administrators within this industry.
