what is a network administrator?

Virtually every organization needs an online network to process sales, host websites, interact with customers, record data and utilize business software. If the network goes down, they could suffer from a data breach or lose tens of thousands of dollars in sales. Network administrators create and maintain systems that keep businesses running 24/7.

If a new company reaches out, you'll set up a new system with firewalls, anti-virus software and other protective measures. Existing businesses hire you to upgrade their technology, patch security holes and analyze their system's performance. You'll think ahead so that operations protect their data from the beginning instead of scrambling after a breach.

Network administrators install and maintain local area networks (LANs), wide area networks (WANs) and other equipment. Your hardware and software expertise enables you to maintain the entire system. You'll also train new employees so that they can maintain the system when you're not around. However, you're still the first person that your company calls when they need your expertise.

While you'll focus on network administration, you'll supplement your knowledge with skills in programming, web development and cloud technology, making you even more valuable in the workplace.

network administrator skills and education

Most network administrators seek higher education. Some employers accept an associate degree, but many prefer a bachelor's degree in a technology field such as computer science. You can pursue a traditional four-year degree or take an accelerated program that gets you on the job market in less than two years.

College teaches you technical skills, including:

  • system administration
  • technical support
  • Microsoft Active Directory
  • Windows Server
  • Cisco
  • Domain Name System (DNS)

Employers require certifications when they need specific skills. Two common certifications include the Cisco Certified Network Associate (CCNA) and CompTIA Network+ certification. Passing these exams proves that you've mastered the basics, such as problem-solving, IP addressing and working with infrastructure.

Additional certifications include:

  • CompTIA IT Operations Specialist
  • LPI Linux Essentials
  • Amazon AWS Cloud Practitioner
  • CompTIA Secure Infrastructure Specialist
  • CompTIA Project+
  • Amazon AWS SysOps Administration-Associate

Certifications open more job opportunities, but you don't need every single one to secure a position. Additionally, you don't need to earn them all at once. You'll gain more certifications as you advance throughout your career. Likewise, you'll periodically refresh your knowledge by tracking industry updates.

skills and competencies

On a basic level, you'll need troubleshooting, problem-solving and communication skills. In fact, many network administrators start as IT workers. You'll learn how to use basic software, such as Microsoft Office, and help others with their technology problems. As a network administrator, you'll perform similar tasks on a larger scale.

Likewise, critical thinking helps you find solutions for your client. If hackers keep threatening your company, should you strengthen the security system, install new firewalls or overhaul the network altogether? When new technology rolls out, should you upgrade the network or stick with the system that works? You'll make the best decisions for your team.

Network administrators also write and understand programming languages, including:

  • HTML
  • Ruby
  • Python
  • Java
  • PHP
  • C++

Sometimes, your employer might ask you to complete tasks outside your main responsibilities. They want an expert in nearly everything:

  • programming
  • installing hardware and software
  • troubleshooting devices
  • analyzing data
  • operating telecommunication networks

Finally, network administrators are time management experts. You complete projects on time, and if an issue outside your control forces delays, you'll notify your supervisors and get the project back on track. When you work overtime, your employer notices and appreciates your dedication to your job.
