The definition of hardware describes a physical component of a computer and the way that it functions. In order to understand more about our computers and the way they work, we have to understand more about their elements. Furthermore, knowing more about the role of each part of your computer can help you recognize when something doesn’t run as it should, and it can allow you to fix any type of problem without having to lose too much time or spend too much money.
Before focusing on the definition of hardware, we must be aware of the fact that there are two types of hardware devices. The internal hardware operates without having to be controlled by the user, while the external one integrates components that are visible, and that need to be handled by the owner in order to perform.
An internal hardware integrates the following items:
- The motherboard, which is the principal circuit board of a computer can be identified very fast as it is the largest piece of silicon that you can see when you open your computer. Attached to it you will find the ROM, the memory RAM increase slots, the CPU, the PCI slots, and the USB ports. It also represents the element that controls the keyboard, the DVD drive, the mouse and the hard drive. So, it makes everything in your computer function together.
- The hard drive is the component that stores all the data and information that exists in a computer. It locates all the user’s folders and files, and it can hold over 100 GB of data. Its solid encasement futures a stack of disks that are used to store all the existing data. They are located inside the driver, and they spin very fast because only that way the data can be accessed immediately. However, the most impressive thing is that the data is captured on the hard drive magnetically, so it remains stored even after you turn off the power supply.
- RAM is the abbreviation of “Random Access Memory”, and it incorporates small memory chips which form a memory module. Furthermore, these modules are integrated in the RAM slots, so every time a program is opened it gets loaded from the RAM, because the process of reading data is much faster this way.
In order to complete the definition of hardware, we must present the elements that an external hardware includes: the monitor, the keyboard, the mouse and, depending on the computer’s improvements, a printer and a scanner.
