All of the basic parts of a desktop computer are considered hardware. The computer case, monitor, keyboard, mouse, and power cord are considered the basic parts. These items are the things you notice right away when you look at a desktop computer.
Beyond these parts are the hardware items that are located inside the computer case and the peripherals, which are optional pieces of hardware that make the computer system more useful, or enable you to accomplish additional tasks. Let's take a look at the basic hardware components, or the things required in order to let you and the computer interact.
The computer case is the metal and plastic box that contains the main components of the computer. It houses the motherboard, central processing unit (CPU), the power supply, and more.
The monitor works with a video card, located inside the computer case, to display images and text on the screen. The two main types are cathode ray tube (CRT) and liquid crystal display (LCD) monitors.
The CRT monitor is big, like a tube television, and takes up a lot of desk space; however, it is the least expensive monitor option. The LCD monitor is thin and saves energy, but costs more. Over the years you can expect to see fewer CRT monitors as LCD monitors become the standard.
Your monitor has an on/off button and control buttons that allow you to change your
monitor's display. Control buttons are either visible or located behind a small panel.
additionally, some monitors have built-in speakers.
The power cord is the link between the power outlet and the power supply unit in the computer casing. If the power cord is not plugged in, the computer will not power on. It is a good idea to keep the power cord plugged into an Uninterpretable Power Supply (UPS), which serves as a surge protector with its own temporary power source.

The keyboard is a piece of hardware that resembles a typewriter keyboard. It is one of the primary ways we communicate with the computer and enter data. There are many different types of computer keyboards such as wired, wireless, ergonomic, multimedia, and more. Although there may be differences in the location of some keys or features, keyboards are very similar and allow you to accomplish basically the same tasks. The images below show you three different types of keyboards.
The mouse is a peripheral that is known as a pointing device. It lets you point to objects on the screen, click on them, and move them. Previously, it was considered an optional device, but now all desktop computers will come with a mouse.
There are two main types of mouse -- optical and mechanical. The optical mouse uses an electronic eye to detect movement and is easier to clean. The mechanical mouse uses a rolling ball to detect movement and is more difficult to clean; however, it is less expensive,so many computers come with a mechanical mouse.
