The computer world seems as if it speaks a language of its own. There are terms such as hardware, software, CPU units and devices, which all have a unique meaning in the technological world. If you are just starting out in the technological world, these terms can be very confusing. However, by taking a closer look at some of the words, you will be able to understand exactly what these terms mean. Here is a look at what the term “computer hardware” means and some examples of what exactly computer hardware is.
Computer hardware is the term that is applied to any physical aspect of the computer. These are items of substance—they can be held, moved around and touched. There are over a hundred different types of computer hardware available.
Here is a look at some examples of computer hardware and the functions that each item performs.
Central Processing Unit (CPU)
The central processing unit is the core of any computer. It consists of the small machines that allow the computer to interpret numerical sequences and process it so people can use the computer.
Computer Fans
Computers use energy which can often generate heat. In order to not overheat or prevent a system overload, computers contain a fan that will cool down the various elements within the computer. The computer fan is an example of computer hardware.
Discs
Discs are generally used to store information or present information to the computer user. Discs can come in a variety of ways, from Blu-ray discs to compact discs. These discs can also come in the form of a blank disc so that information can be stored on it or with pre-loaded information.
