Some organizations might use system administrator and network administrator interchangeably, and there are many overlapping responsibilities. But there’s technically a difference. System administration focuses on servers and computer systems, while network administrators work more specifically with network-related tasks and equipment, like setting up routing, IP addresses, and maintaining Local Area Networks (LAN).
If you’re in a smaller organization, these responsibilities might be folded into one role, while larger organizations may tend to differentiate them. Since systems and networks are often intertwined, it’s not rare to see job descriptions that require knowledge of both.
Becoming a system administrator will entail learning some specialized skills. Earning a certification can bring you needed experience and enhance your resume.
As a sysadmin, you’ll need to develop a core set of skills that will allow you to make sure the computer systems in your organization are running smoothly. Here are the top skills that you’ll want on your resume:
In-depth knowledge of operating systems: Whether it’s Windows, Linux, or Mac, hiring managers generally look for competency in administering the operating system used in their company. Windows and Linux operating systems have been widely embraced and are good systems to start with, though it’s a good idea to check if your industry favors one over others.
Familiarity with hardware: Working physical devices—such as servers or printers—will be an important part of a system administrator's job.
Cloud computing skills: Familiarity with cloud applications like Office365, Google Cloud Platform, and AWS can give you a boost in the hiring process.
Knowledge of networks: Being able to set up and maintain Local Area Networks (LAN) and Wide Area Networks (WAN), in addition to setting up network security features like firewalls, are often expected of system administrators. This might often be the case at smaller companies, where IT professionals are expected to wear many hats.
Communication and interpersonal skills: In addition to working on a team, sysadmins will often be expected to help other employees that don’t have the same technical knowledge, through help desk support or other means. Being able to communicate well will be a key part of a system administrator’s successful day-to-day tasks.

There are several certifications you can take in order to gain experience as a systems administrator.
Having knowledge of Windows servers is likely to be a significant asset as a system administrator. The Windows Server Administration Fundamentals certification will qualify your expertise in Windows servers, networking, Active Directory, account management, and system recovery tools.
The Google IT Support Professional Certificate equips you with the skills to tackle common sysadmin tasks such as customer support and troubleshooting. It also introduces you to commonly used systems like Linux and Domain Name Systems, and prepares you for the CompTIA A+ exam. Though not a certification, the course will earn you an industry-recognized professional certificate at the end. It requires no previous experience.
Getting the Red Hat System Administrator Certification will give you the needed experience with Linux operating systems to land an entry-level job in systems administration.
CompTIA offers several certifications that are designed to prepare you for entry-level positions. The Server+ or A+ certifications in particular will leave you with the necessary skills and experience under your belt to start applying for entry-level IT jobs. While you’ll gain specialized knowledge around servers with the Server+ certification, the A+ certification covers a broader set of skills applicable to other aspects of IT.
Preparing for any interview means anticipating some questions ahead of time and knowing how to answer them. Here are some basic questions you might encounter when you interview for a system administrator role.
Describe your experience with hardware.
How would you deal with a virus?
How would you know when to upgrade a server?
Tell us about a time when you weren’t able to solve an issue. What did you do?
What qualities do you have that make you a good system administrator?
Since IT jobs are highly technical, interviewers are likely to ask you several technical questions in addition to more personal behavioral questions. Be prepared for both. Refresh your IT skills by mentally walking through several tasks you know how to perform, and practice explaining them aloud.
It’s a good idea to think about some stories of when something went well for you, and when things didn’t go so well—and what you did in that situation to make it better. Having concrete examples at the ready can help you feel mentally prepared and appear more confident to employers.
Explore the skills and tools used by IT professionals by enrolling in the Google IT Support Professional Certificate. You'll learn to perform day-to-day IT support tasks like computer assembly, wireless networking, and customer service to get job-ready for an entry-level IT job in just six months.
System administration roles can be divided into four general categories:
While sysadmins might not be expected to write as much code as a software engineer, the role does require some small script writing. You don't have to be an expert, but understanding the concepts behind languages like PowerShell, Bash, JavaScript, and SQL could make you a more competitive candidate.
The most common entry-level credential for sysadmins in the US is a bachelor's degree, though some employers will hire qualified candidates with a certification or associate's degree.
According to Zippia, 60 percent of sysadmins have a bachelor's degree and 24 percent have a associate. While it's possible to get a job as a system administrator without a degree, earning one in a topic like computer science, networking, or IT could open up more opportunities [2].
