Network Administrator Career Guide

Every day, the staff of a company needs to communicate with each other, customers, and management. They need a place to access, change, and store information. This all needs to happen reasonably quickly and safely. In order for a company to continue its operations, they need to have safe and reliable networks with which to operate.

Network administrators ensure the integrity of the networks they maintain and help to make sure the information on said network stays away from any prying eyes. These experts oversee the installation of hardware and software, resolve network issues, and fix physical hardware associated with the network.

In order to succeed in this position, you’ll want to have a thorough understanding of networking services and operations. Having excellent proficiency with computer systems and hardware is a big plus. Strong written and verbal communication will benefit those in this position as well.

It’s crucial for a network administrator to stay up on the latest trends. According to the tech company Cisco, the move to 5G technology is one trend that network administrators must be aware of in the coming years. 5G is the fifth generation of cellular technology, designed to increase the speed and flexibility of wireless services.

The increasing size of the Internet of Things (IoT) is another trend network administrators should follow. More and more objects are becoming “smart” and connecting to computer networks to communicate with other objects and people. Some industry analysts think IoT could be a transformative, permanent paradigm shift.

Also, more network administrators will be called upon to develop their soft skills in the coming years. Network administrators have to interact with people at all levels of an organization, which means communicating complicated ideas to people who may not have a great deal of technical expertise.
