The internal parts of a computer They are the different hardware components that are inside a computer system so that it can work. These elements are found in almost all computers.
Although the design of the internals is different between desktop PCs and laptops mainly due to their differences in size, the same main components will be found in both types of computer.
While a computer is only good for work when hardware and software are used together, the speed of the system as a whole will have a lot to do with the internals employed..
When building a new computer or replacing parts of a new computer, you may need to know the specific internals of a computer..
It is the main board that contains all the circuits to connect the devices and components. It is designed according to the type of CPU. It contains all the major components of the computer, including hard drive, processor, memory, graphics card, etc..
Most motherboards are expandable as components can be replaced as long as they are compatible. For example, you can replace a hard drive with another that has a larger storage capacity..
It transfers all the data between the internals, allowing them to communicate with each other. The bus width refers to the number of bits that you can simultaneously send to the CPU.
It is also known as the Central Processing Unit or CPU. It is the brain of the computer, controlling its basic functions. It is responsible for reading and executing the instructions of computer programs that are stored in the computer's memory..
It also collects and saves the data that will later generate the information to be displayed after having executed the instructions..
The speed of a processor is measured in MHz. This measurement indicates how fast a processor can read electrical pulses. For example, a 100 MHz processor can read 100 million pulses in one second.
It has two main components, which are the control unit, whose function is to direct the system to execute the instructions. The other component is the logical-arithmetic unit, whose function is to execute all the logical and arithmetic instructions.
It means "basic entry and exit system." It is a chip that contains the instructions and settings on how the system should boot. Ensures that everything is stored on the hardware and that everything works properly.
In addition, it ensures that there is no problem with the operating system and allows the user to configure their settings, such as time and password. The boot loader is a program that loads the operating system after performing all the self-tests on the computer..
It is a fan that expels the existing hot air inside the computer case, preventing overheating of key components by preventing heat from staying in one place, transferring it away from the source that generates it. It is an essential part of a computer's cooling system.
Thanks to the heat sink, computers run fast. Without this, the computer runs the risk of overheating, which would totally break it.
It stands for "Serial Advanced Technology Attachment". Its function is that the cable can be used to connect storage devices, such as DVD-ROMs and hard drives. It has been designed to reduce transmission noise and improve airflow in the system.
It is a type of temporary or volatile storage of computer data. It takes care of temporary data requests, such as keeping windows open on a desktop or simply viewing a file. When the computer shuts down, the RAM loses all the data it contains.
The function of RAM is that when a program is opened, it is stored in RAM from the hard disk. Data obtained from RAM is much faster.
It is a type of memory that cannot be modified. Unlike RAM, which is erased when the power is cut, ROM remains as is, unchanged. These chips cannot be exchanged as the code was loaded when they were manufactured.
Therefore, it stores data and startup instructions permanently. This information cannot be destroyed, unless all its content is deleted forever.
Its function is to send / receive data at a high speed to / from the processor, before they go to RAM or ROM, since these memories work with less speed. This speeds up the overall operation, by making the data immediately available to the processor.
Programs and files are permanently stored on this unit. More traditional drives are called hard disk drives (HDD) and are made up of a series of magnetized disks that spin rapidly to store data..
The newest ones are called solid state drives (SSDs) and they use electrical circuits to store data. These are much faster than traditional hard drives.
It is a unit to read compact discs and also DVD. They use lasers to read the data on the disk. They connect to the motherboard usually via SATA cables.
It is used for multiple computers to communicate with each other over a network, also providing a way for a computer to connect to the Internet.
Its function is to create the graphics and images to be able to display them on a monitor. Without this card the data could not be displayed and therefore the computers would be useless. It also produces better quality and faster online games and videos. This means that the resolution is much better, and the video can be seen better..
Some graphics cards have their own graphics processing unit to quickly process 3D graphics..
It can be integrated, connecting directly to the motherboard as part of the processor, or expansion, which is a separate card that connects to a part of the motherboard called an expansion port..
It converts alternating current from external electrical sources into low-voltage direct current so that all internal parts of a computer can operate without interruption. It also regulates the heat of the device, preventing overheating.
