Network administrators are in charge of a wide range of computer and Internet-related tasks, but the majority of their responsibilities fall into three categories: system design, maintenance, and troubleshooting. The actual coordination of a computer network, from setting up the central server to linking and testing all users’ connections, is referred to as construction. Routine testing of the network’s fidelity, as well as the installation of updates and security patches as needed, are all part of keeping the network up to date and safe from outside threats. A network administrator’s troubleshooting responsibilities typically include listening to client problems, diagnosing bad connections, and finding solutions, whether in person or remotely.
Many businesses, organizations, and even households rely on computer networks. A homeowner setting up a wireless network for his family and a corporation with an established server connecting desktops, laptops, and mobile devices may not appear to be all that similar at first glance, but both rely on network administration personnel to some extent. The administrator of a home or small business server might only be reachable by phone. At any given time, most corporations have entire administrative staffs on call. The specific responsibilities of a network administrator vary depending on location and work situation, but most professionals share a core set of skills and perform similar work, albeit on a smaller scale.
One of the first responsibilities of a network administrator, especially in large organizations, is to set up a computer network. With a little time and study, users can often set up their own networks in their homes and smaller-scale settings. The complexity of the task at hand determines a lot. A basic wireless network is usually simple to set up, but synchronized e-mail routers, linked folders visible to a large number of users at once, and coordinated server storage space are typically tasks for someone with specialized network engineering training.
Once a network has been established, it is usually necessary to maintain it in order for it to continue to function. Creating new accounts for new employees and removing the privileges of those who leave can be as simple as that. The task frequently entails much more proactive monitoring, such as vulnerability testing, keeping an eye out for needed updates, and installing security programs. Filters for e-mail and network management software are also included.
In many organizations, a network administrator’s maintenance responsibilities also include employee training. In these situations, administrators must hold regular seminars or mandatory meetings on topics such as how the network works, how to properly download and share files, and basic Internet safety precautions, to name a few. The goal isn’t to turn users into administrators on their own; rather, it’s to arm them with the knowledge they need to make good decisions and help prevent network disasters.
Because nothing in technology is foolproof, network administrators must be capable of troubleshooting and problem-solving. Some of this is dealt with on a case-by-case basis. Users who are unable to connect to the internet or access specific files usually contact a network analyst first. Most companies rotate their administrators through shifts at the help desk, where they answer calls and resolve issues.
Troubleshooting can also take place at the level of a larger computer network. When parts of a network go down, or when multiple computers lose access at the same time, a network administrator with network engineer skills will usually be called in to diagnose, assess, and resolve the issue. When dealing with complex network failures, administrators must frequently collaborate and work together. This may entail rerouting certain connections or recoding specific network segments, but it may also necessitate more complex fixes such as network equipment replacement or system upgrades and overhauls.
