The computers are made up of many parts that work logically and guarantee the automation of numerous tasks. To do this, they must have with software and hardware support; that is to say, it has to exhibit a perfect functioning of the “soft” and “hard” part, respectively.
In this sense, the hardware make reference to the “hard” part of a computer system and basically, it consists of the tangible physical segments. Which are made up of electrical, electronic, electromechanical and mechanical components.
If you want to know more closely what are the parts and peripherals that make up the physical structure of a computer to operate properly, we recommend you continue reading. Here we will detail the main parts of a computer and their functions.
Most important hardware of a computer and its functions
The hard part of a computer system is based on a set of components that they need the white part to be able to function. In such a way, each of the physical parts of the computer are responsible for a set of specific functions that provide the machine with the ability to perform multiple tasks. Hence the importance of knowing what are each and every one of these most relevant hardware parts of a computerdetailing what they are for.
All this, you can know below:
Keyboard
Also know as keyboardthe keyboard is an input device that has its own processor and various digital circuits capable of enter the information at the same time it is displayed on the screen. This consists of several keys that act as electronic switches with printed characters corresponding to written symbols.
Thus, the main function of a keyboard on the computer is provide a more comfortable, practical and faster way to enter data into it, through a keystroke. Taking into account that, it uses a stitch system that is responsible for sending the information to the team. Currently, there are which are summarized in: Mechanical, membrane, ergonomic, RGB, wireless, gaming, virtual, tablet, handheld, vertical, roll-up, etc.
Mouse
It is defined as an input device or pointing device that deals with translate the movement of the user’s hand into signals that the computer detects, recognizes and interprets to locate itself in a specific position on the screen. Therefore, it serves to interact with the operating system interface.
Regarding its operation, this piece of hardware is designed to slide on a flat surface and thus, it is captured by means of a sensor that acts as a receiver of movement information and transforms it into data to send it to the team. For it, it has two buttons: The right one that is used as a shortcut to menus and the left one that is used to execute actions of activating, accessing, moving, etc.
In general terms, two are handled : mechanics (they have a rubber ball that rolled in all directions and is the most obsolete) and opticians (they have a laser to detect movement and guarantee high performance).
CPU or processor
This is an electronic circuit that has the function of run all calculations on a computer. In other words, it is responsible for producing the set of instructions for computer programs. Therefore, once you access a software, the information will be sent to to consume useful information. That is why it is identified as the brain of the computer and its operation is divided into 4 fundamental processes to guarantee optimal data processing.
These processes are: Go, Decode, Execute and Rewrite. In the stage of Go, the CPU retrieves the instructions from the program and stores them in memory. After, during the Decode stage, proceeds to interpret each instruction. Subsequently, in the Execute stage, carry out the operation following all the instructions. Finally, at the time of rewritingwrites the execution results back to RAM.
Motherboard
The “” is the main card of the computer and is characterized by containing the sockets in which the processor is installed. So this is a piece composed of a set of chips and integrated circuits where the other parts of the equipment connect. Consequently, the motherboard of a computer it is one of the most important hardware parts of all.
Well, in it the storage units, the processor, the RAM memory and other elements that allow the computer to start up and the recognition of any peripheral. In addition to connecting all the parts of a computer to simplify communication with each other, this part that works as the backbone of the computer is responsible for gathering all the data sent by the other segments of the computer.
RAM
The “Random access memory” it is a silicon chip that temporarily stores data on the computer. Thus, it is a component that retains the information with which the user is working at a given moment. Therefore, it stores the data and results whose use will be temporary. Therefore, it serves so that the team can execute the actions more quickly. Since, if you only use the hard disk for it, could not perform tasks immediately.
Noting that this type of memory stores the instructions of the CPU or the data that the programs constantly require. In general, two are known: DDR and SDR. In the case of the first, it is the one capable of execute two operations in each clock cycle. Whereas, SDRs only execute a read or write operation.
graphics cards
It is a component that also is distinguished as “video card” and it is a part that is integrated into the motherboard of the computer or is installed additionally to expand its capabilities. So it works like an expansion card. Thus, computer graphics cards are an element dedicated to data processing related to the video and images played there.
Therefore, thanks to them, the computer can receive and process a greater amount of digital data on the screen. To reveal optimal functioning, it is a part that It has its own RAM memory and a separate processing unit.. This, with the aim of not affecting the general performance of other components. In that way, simplifies graphic design, video editing and gaming taskswithout the computer does not slow down.
Power supply
Basically, it is a device that is placed in the computer cabinet to be able to transform the alternating current of the commercial electronic line into direct current. With which, it manages to feed certain electronic and electrical elements necessary for the correct operation of the equipment.
It is because of that, one is made up of many wires that are connected to the most important parts of the computer (including hard drive and motherboard). Through this, it sends the exact voltage that each component requires to function uninterruptedly and without failures.
In general, this part of the equipment is classified into: Linear sources and switching sources. The first ones are designed in a simple way, but their tension function is not the most suitable. On the other hand, switching sources are smaller than linear sources, but reveal high efficiency.
Display
The, screen or display unit is defined as an output device that has the function of represent the interface of an operating system, visually. This exhibits the appearance of a conventional television and presents the processed information in the form of pixels. Thus, the monitor facilitates the interaction between the user and the machine. Added to this, it allows the management of different tasks that are carried out through the computer.
Thus obtaining an immediate response in the form of text and images. Among the main particularities that differentiate the monitors from each otherwe highlight: Screen size, panel type, resolution, brightness, aspect ratio, response time, input connectors, refresh rate, curvature, viewing angles and sync technology.
reading units
Consists in a data entry and reading element which is connected to the motherboard of computers. In other words, the reading units are those that analyze a storage device, either magnetically, optically or virtually. Apart from this, such units also They allow you to store the files that are located on the hard drive, through external storage device. This being the secondary function of said hard part of the computer.
Regarding its classification in terms of storage, we have: By magnetic means which are ideal for storing a large amount of data in a small volume; by optical means that are used to store information permanently and, by virtual means which is the most modern technology with greater efficiency and is carried out with SD memory cards, SSD drives and USB flash drives.
HDD
It is a part of the computer that is also identified as “” and it has the function of storing all kinds of files or digital data in various formats. That is to say, it saves the information that the user must handle on his computer and provides quick access to large amounts of data and programs. For this reason, the hard drive is used to house any type of information (text, multimedia, software, etc.) on the computer. for an indefinite time.
So, unlike RAM, they don’t matter if the computer is turned off, because Likewise, the data will remain saved in this component. For its part, this electromagnetically charged surface resembles a record player arm that has the ability to read and write data on the disk surface. Usually allows you to store from 120, 250 and 500 GB up to 4 TB of information on desktop computers.
