The Computer Systems Administrator is responsible for overseeing the operation of an organization’s entire computer system, including installation, updates and maintenance. This means they essentially organize, install, and support the systems, which include local area networks (LANs), wide area networks (WANs), intranets, and network segments. Networks are essential in the workplace in today’s world. Without properly working networks there would be no internal email, data storage, and even telecommunication through desktops and mobile phones.
Computer Systems Administrators or Network Administrators start by meeting with the business or client to determine what they need in a network and computer system before it is set up. Some may already have something set up and simply need someone to maintain it or upgrade it, but determining what they need first is always important. After deciding on what they need, they can then start the installation of all network hardware and software. After installation they can make any needed upgrades and repairs as they come along. It is important that connectivity of the LAN/WAN infrastructure is on par with technical considerations and all of the software function properly together, so regular maintenance of the networks and system security ensures system efficiency. After a successful system install, constant data gathering on performance helps to evaluate the network or system performance and will help make the system work better and faster.
Once the networks are up and running properly, it’s time for the Computer Systems Administrator to evaluate the users’ needs and then add users to the network and assign and update their security permissions to use the network. Once they have been added, they must train the users on the proper use and handing of the hardware and software as well as any security issues and information. After the user has been added and trained, the administrator will also continually help solve any problems the user may encounter. The administrator will help the user with servers, desktop computers, printers, routers, switches, firewalls, phones, personal digital assistants, smartphones, software deployment, security updates and patches.
If applying for a Computer Systems Administrator, your resume should include your ability to organize, install, and support systems including LANs, WANs, intranets, and network segments. You should also be able to describe an install process for each position you have already had as well as how you maintained the networks and worked with the end user on solving problems that may arise. Different companies have you involved with different setups so be sure to add what systems you administered such as smartphones, desktops, router, switches, security etc. Lastly, include any system upgrades or repairs that may have occurred. Knowing what the newest systems and upgrades are, are important to a hiring managers since they like to see proactive systems administrators that are constantly trying to improve the company’s performance.
