Main hardware elements They are the monitor, mouse, hard drive, motherboard, case, and keyboard. Some of these components, such as the mouse or monitor, are quickly visible.
Others require the computer case to be opened, because they are delicate components that are enclosed to protect them from environmental hazards..
Although these items are considered essential, there are some that are used only out of habit and others that can be replaced in some ways..
The monitor is the means that the computer uses to communicate with the user. For example, when words are written in a text program, they appear on the monitor screen, so that it is known that the computer has registered them correctly..
This item can also be used as a TV or even as a movie screen.
After its introduction in 1964, the mouse has slowly risen to the status of an essential component of a computer installation..
It is used to move an arrow on the screen that controls graphic elements of the programs.
Despite this, it is not an absolutely necessary element. Many computers of the past and specialized computers, such as servers, were operated and continue to be operated only with the keyboard.
Since the beginning of the commercialization of computers, the keyboard is the most important component for a user to communicate with the machine.
Although the mouse is being replaced in certain types of computers by touch screen technologies, the keyboard is still essential and is included even if it is digital.
The case protects the internal elements of the computer from hazards in the environment.
The most common case is a black box made of aluminum with fans, but there are countless variations of case designs.
The motherboard is an internal element of the hardware that corresponds to the center of the computer. It is the central place where all the internal elements are connected.
Mounted on the motherboard is random access memory (RAM), which the computer uses to quickly store and retrieve information..
There is also the processing unit, which does all the necessary calculations; and the video card, which is required to send graphic information to the monitor.
The motherboard and most of the components that make it up are those required for the computer to function..
The most direct information for the user is stored on the hard drive. This disk allows long-term storage of data.
The hard drive looks like a metal case. In the past, most hard drives had memory saucers inside of them..
Currently, SSD disks are becoming popular, which use microchips to store information.
Known briefly as GPU, it is the integrated circuit with the function of processing the data sent by the processor and transforming it into information visible to the human eye through the monitor. Graphics cards can be of two types: integrated and dedicated.
It is responsible for converting alternating current into direct current. Depending on the consumption of the computer, the power supply must be more or less powerful so that it can provide adequate support.
Computers typically overheat, rendering them useless. With these components, the temperature of the computer is regulated and maintains its proper functioning. Heatsinks can be liquid, passive or air cooled.
