In this modern era, generally speaking, two things that are important in building technology, beside the humans or users; they are hardware and software. Both are tied in system needed to achieve a certain goal. In this article we will focus on the hardware and computer hardware technicians.
But first we have to know the definitions of hardware. Hardware is one of component in computer system that can be seen and touched by humans directly or made real, which is used to support computerized processes. Hardware can be used based on predetermined orders, or also called the instruction set term. With the command that can be done by hardware, it can perform various activities that have been determined by the user.
The main part of computer is the Central Processing Unit (CPU), which acts as the brain of the computer. To be able to work, the CPU requires an input tool to enter information without a command. The results will be seen through the output device. Information or data can also be retrieved and stored form and to media storage.
Physically, the computer consists of several components which are a system. Systems are components that work together to form a unity. If one component is not executed, the computer will not function properly. Based on the function of hardware, computer hardware is divided into:
- Input unit
- Processing unit
- Output unit
- Storage unit
- Additional units
We found some job vacancies about computer hardware engineering for entry level in Linkedin jobs. There are so many vacancies including hardware engineer, electronic hardware design engineer, entry level hardware engineer (government and non-govt), entry level manufacturing engineer, entry level digital hardware electrical engineer, entry-level RF engineer, entry level embedded systems engineer, entry level reliability engineer, entry level hardware and mechanisms design engineer, power electronics engineer entry-level. Turns out there are so much different specialities from hardware engineering. If you are into this field, you can choose and consider it for these jobs.
