Computer parts are among the most important things that are needed to optimize and use a computer. These components include a set of electronic components that are used to perform various activities in the computer.
In addition to hardware components, peripherals are also essential for optimal use of a computer. For example, keyboard and mouse are used as input devices to the computer. Also, headphones, speakers and webcams are also used as audio and video accessories in the computer. قطعات و لوازم جانبی رایانه
Computer parts and accessories play an important role in improving the performance and usability of the computer. With the use of suitable and efficient parts, the performance of the computer can be improved and the user experience can be improved, so it is necessary to access them and the right place to buy them should be identified in order to use it as a purchasing reference.
In this article, we will review all types of computer parts and accessories so that you can act more appropriately if you buy or sell these products.
All kinds of computer parts1. Processor
The computer processor, as the intelligent heart of the system, is one of the vital and key components in the operation and performance of the computer. This basic part is responsible for performing calculation and control operations in the system. Therefore, choosing and using the right processor is very important for better and optimal computer performance.
Multi-core processors have the highest performance. With more cores, more parallel processing is done and system performance improves.
Processor speed is used as a measure to measure its processing power. Processing speed is expressed in units of megahertz (MHz) or gigahertz (GHz).
Processors have a cache that is used to store and quickly access data and instructions. Advanced processors can support new technologies such as multi-core chip technology, artificial intelligence, virtual reality, etc. These features can improve the performance and efficiency of the computer.
2. RAM memory:
RAM memory (Random Access Memory) is one of the most important and vital components in the computer system. RAM is used to store data and programs running on the device.
RAM memory acts as a semiconductor memory that provides fast and parallel access to data. In technical terms, RAM memory is known as primary memory or main memory of the system.
The main function of RAM memory is to store data and programs that are being used and running in the system. When a program is executed in the system, its required parts are transferred to the RAM memory to be accessed by the processor. Also, the data that is being used while the program is running is also stored in the RAM memory.
RAM memory has different capacities, which are different based on the type of system used and the needs of users. RAM memory capacity is often specified in gigabytes (GB), such as 4GB, 8GB, 16GB, etc.
The RAM memory is usually upgradeable and expandable. By increasing the capacity of RAM memory, the ability to run programs and the efficiency of the system is improved. But it should be noted that the operating system and running programs should also be able to use more RAM memory.
3. Hard disk:
Computer hard disk (Hard Disk Drive) is one of the main components of the computer system that is used to store and access data. Hard disks are often used as the primary storage device for computer systems.

Hard drives have a large storage capacity that can store up to several terabytes (TB) of data. This capacity is determined based on the number of disks and their magnetic layers.
Hard disks have a relatively lower reading and writing speed than RAM memory, but due to their high capacity and relatively low cost, they are used as permanent and main memory for data storage.
Hard drives are commonly referred to as the C drive in the operating system, and files, programs, operating system, and other data are stored there. Also, hard disks are available in different types, including internal hard disk, external hard disk, and external hard disk, which are used depending on the needs of users. In recent times, with the advent of solid state drives (SSD), which have high speed and better performance than hard disks, the use of hard disks has decreased.
4. Graphics card:
Graphics card is one of the important components of the computer system, which is used to process images and display graphics on the screen. The graphics card acts as a graphics processing unit (GPU) which is responsible for converting numerical data into displayable images.
The graphics card consists of advanced graphics chips that have their own processing units and memory. These cards receive graphic data from the main processor of the system, usually the CPU, and process them quickly and optimally, then send the final images to the screen for visual viewing.
Graphics cards are used for a variety of tasks, including computer games, graphic design and editing, simulation and virtual reality, and scientific processing.
Graphics cards usually come in as separate components and plug into a specific port on the motherboard. Also, some systems have multi-part graphics cards that are located as a part or chip inside the motherboard.
5. Power supply:
The Power Supply Unit or PSU is one of the main components of the computer system, which is used to supply the required power to all the internal parts of the system.
The power supply is responsible for converting alternating current (AC) from the household power grid to direct current (DC) required for the operation of internal components. The power supply has different connectors and outputs that can send power to different parts of the system. These parts include CPU, Graphics Card, RAM, Hard Disk, Optical Drives and other internal parts of the system.
Choosing the right power supply for the system is important because if the power of the power supply is less than the system needs, it may cause problems such as interruptions in the system’s operation.
Computer accessories1. Screen:
A computer screen (Monitor) is a device that visually displays images and graphic content. Screens consist of different types such as LCD, LED, OLED and CRT and are used to display images, text and videos.
Screens have pixel units that make up images. Each pixel can display one color and by combining these pixels, the final image is made. The resolution of the screen depends on the number of pixels per inch (PPI or Pixel Per Inch) and usually expresses the quality and clarity of the image.
The screens have different sizes that can be selected based on the needs of users. Screen size is measured in inches and usually ranges from 17 to 35 inches. A larger screen usually provides a better visual experience and is suitable for graphics work, computer games and entertainment purposes.
2. Keyboard and mouse:
The keyboard is one of the main components of the computer system, which is used to enter information and control the operation of the computer. The keyboard has a set of keys that include letters, numbers, punctuation marks, and special keys. By pressing keys, the user can enter text, commands, and special commands into the system.
The mouse has a ball or optical sensor that controls the movement of the pointer by moving the user’s hand on a flat surface.
A mouse usually has two or three buttons, each with specific functions. The main mouse button, located at the top, is used for selecting and clicking. The second mouse button (usually on the right) is called right-click and is used to access context menus (menus invoked by right-clicking). Some mice also have a middle button (usually located between the two main buttons) that is used for certain functions such as scrolling the screen.
3. Loudspeaker or headphones:
To hear quality sound, use quality speakers or headphones.
4. Game category:
If you plan to play computer games with a gamepad, choose a gamepad with good quality and compatibility.
5. Cables and accessories: Use the required cables and accessories to connect parts and accessories.
