Let’s get started!

Network Administrators: What on Earth are they?

A network administrator forms the backbone of an organization. They are the people responsible for keeping the network systems and computers running smoothly with security.

The jobs of a network administrator may vary based on the size of a company. But the basic thing always remains the same, which is to set up the network, monitor them, and fix any issues related to networking.

What does a network administrator do?

The days of a network administrator are unique and challenging. It demands you to be versatile and capable of adapting to change. In addition to technical knowledge, you need to multitask while staying focused on your job.

In a small company, they can supervise all the aspects of a computer system, ranging from setting up a network to hardware installation. Sometimes their work may also coincide with a system administrator. A network administrator often works together with the firewall team.

They can collaborate with hardware and software engineers to find actual network requirements and oversee system security.

In a large firm, network administrators may focus on a particular area like system performance. Their work can be flexible where they are involved in researching new software in the office or installing them. They may also be found checking network systems and installing hardware for weeks.

Some duties of a network administrator are:

  • Installing software and hardware when new software releases and systems are updated
  • Repairing software and hardware in case software gets infected, encounter compatibility issues, or device breakdowns.
  • Training new joiners on using software or hardware
  • Checking properly functioning of security systems
  • Monitoring system performance speed and implementing changes when required
  • Adding or removing users and updating permissions
  • Solving issues on the computer system of an employee within the network

As an administrator, you should be also familiar with these network monitoring software.

Why does every big organization need them?

With the growing economic challenges and security threats, organizations hire network administrators for optimizing their existing networks. They need them to increase business productivity and secure their network from vulnerabilities, especially online threats.

Hiring network administrators also help them reduce the cost invested in new systems and damages incurred due to security-related attacks. Not to mention, they also help them secure their business reputation as well by keeping systems updated, so there occur no grounds for loopholes.

As a result, there has been an increased demand for network administrators for the past few years. In fact, many gave dub this career as a “recession-proof” career. And it’s smart to take up a growing field where there’s plenty of chances for handsome income and exciting work.

And that’s what you can expect when you become a network administrator!

Furthermore, organizations are also embracing cloud computing widely, which also increases the need for network administrators. Even healthcare systems are not untouched with the waves of network administrators; they also hire them to handle connectivity between users to the doctors to the systems.

No wonder why the network administrator career is one of the hottest currently. According to a report by the US Bureau of Labor Statistics (BLS), the employment of computer systems and network administrators is estimated to grow 5% from 2018-2028.

What’s the Salary?

Yeah, now comes the exciting part!

Networking is one of the highest-paying career paths in IT. In a similar fashion, network administrators have potential career growth and impressive paychecks as well.
