Desktop computers - also called 'desktops' or simply 'computers' - are machines which are intended to be used at a single location (unlike laptops which are designed to be portable). Before the widespread adoption of consumer computers, a computer used to be incredibly large hence the invention of a computer which could fit on top of a desk was seen as a remarkable achievement. Desktops used to cost thousands of dollars to purchase, although due to technological improvements you can now purchase a desktop computer for as little as a few hundred dollars. They tend to be made up of four main components which are as follows:
Case: the case is mainly metal and plastic and it houses all the hardware (electrical components which make a computer function) inside of it. The below components and other peripherals - plug into the case. Monitor: the monitor displays an interface which allows the user to easily interact with the computer. Keyboard: the keyboard enables the user to type in characters (letters, numbers and special characters such as @# into the computer. These four components are shown in the following diagram: A computer with a case, monitor, keyboard and mouse. These are the four main components and peripherals that a desktop might have. Other peripherals include speakers (which output audio), a printer (which allows the user to print out documents and photos), a scanner (used to scan documents and photos into the computer), a webcam (used to record images of the user or their environment directly to the computer) and more.
