Computer Network Technician Nature of Work

Computer network technicians create and maintain computer networks used by commercial, educational, governmental, and healthcare institutions. In networks that connect desktop computers, users can send email and share data, computer applications, and Internet connections. The more institutions set up computer networks, the greater the demand for qualified computer network technicians.

Computer network technicians, also known as computer network engineers or network specialists, should be familiar with the current standards and terminology used for larger local area networks (LAN) and wide area networks (WAN). They often help plan their employers' computer networks and then implement the planned networks. In most cases, network engineers manage existing computer networks and troubleshoot problems.

Planning a computer network involves analyzing the costs and requirements of a company and choosing the appropriate media (e.g. twisted pair copper cable, coaxial cable, fiber optic cable, wireless) for a specific situation. Computer network technicians can also recommend suitable network addressing systems, suitable designs for different network configurations and suitable connection devices.

Implementing a computer network involves designing and monitoring business plans to meet certain requirements, such as account management and security. Much of the work involved in implementing a network involves installing, configuring, and resolving conflicts between various hardware components used in the network, e.g. B. Network adapter.

Managing and fixing problems with a network involves identifying and fixing problems with network performance. Technicians identify problems that are common among computer network technicians. They plan, design, implement and solve computer network problems for companies and other institutions. (Photo by Kelly A. Quin. Thomson Gale. Reprinted with permission.) Network components such as cards, cables, and other related hardware. They also create disaster recovery plans for various situations in the event of a network failure.

Computer network technicians not only need to know the relevant computer and network terminology, protocols and hardware, but also have to know the required software, including various operating systems such as Novell NetWare, Unix and Windows. You also need to understand basic models of network architecture such as peer-to-peer and client-server.

Computer network technicians need self-discipline and the ability to reconcile a variety of tasks. A technician must be able to spend long hours debugging a program on a keyboard, and must be skillful and patient in the structure of a complex cable network.

Because network technicians often provide technical support to network users, they must be able to help non-technical people understand and use complex devices and software. In addition to technical expertise, employers often require network technicians to excel in verbal and written communication and to have good interpersonal skills.

What is the Windows Subsystem for Linux

We can think of WSL as a compatibility layer that runs between your Windows operating system and a Linux kernel. It is installed as an optional component on your Windows computer or server (in our example Windows Server 2019). Once this level is installed, you can run Linux commands from a Linux command line as if you were sitting in front of a native Linux computer.

This opens up many options for administrators, developers, and software testers who need to quickly test scripts, programs, or commands without replacing computers or turning on a Linux virtual machine.

Why Use WSL?

The first and most obvious reason to use WSL is that the installation causes less headaches than virtualizing a Linux box. This is especially true if you want to run a script on another computer near you. If you run WSL from your server, you can access the network as usual, but on Linux. This leads to a better test experience because if configured correctly when running bash scripts on the network with WSL, little or no configuration is required.

The second reason is applications. Many applications Since the 1990s, some Linux variants have corresponded to application memory that can be accessed from the command line. This pioneering software delivery system has found its way into modern Linux distributions and thus into the WSL.

In Ubuntu WSL, for example, your system can update all file dependencies on your system with a simple command before installing the requested application from an Internet repository.

Progress is largely automated, except for the occasional user request to press the "Y" and "RETURN" keys to accept the installation. Better still, it's completely transparent so you can see every step of the installation on the command line. The WSL works the same way, so the extensive catalog of packages and applications is immediately available.

A third reason to use WSL is to impress your friends and colleagues with your new Linux skills. Starting a bash session from a Windows command line is also a surreal experience at first.

Finally, there is the security problem. Before Microsoft had a reliable patch cycle, Linux systems were seen as the safest option for hosting critical services in companies and organizations. Updating the entire operating system from the command line is a simple task that takes all dependencies into account automatically. WSL is the same. This makes it a safe option as long as you keep your systems up to date.
