Main parts of the computer.

The main parts of a computer include the central processing unit (CPU), memory (RAM), storage (hard drive or SSD), motherboard, power supply, and input/output devices (such as a keyboard, mouse, and monitor). Some computers may also include additional components such as a graphics card, optical drive, or additional storage devices.

I have also divided it into three main parts so that you can easily understand the components of a computer. Their names are given here, and separate articles have been made for them. so that you can know more about them.

  • Internal parts of the computer system
  • External parts of the computer system
  • Physical parts of the computer system

How does the computer works?

A computer is a machine that is capable of performing a wide range of tasks by processing and manipulating data. The heart of a computer is the central processing unit (CPU), which acts as the “brain” of the computer. The CPU retrieves instructions from memory, performs calculations, and manages the overall flow of data in the computer.

The memory (RAM) is used to store data and instructions that the CPU uses in the short term. It is much faster to access data stored in RAM than it is to access data stored on a hard drive or SSD. The hard drive or SSD is where the computer stores data and programs in the long term. This is where the operating system, software programs, and user data are saved.

The motherboard is the main circuit board in the computer, and it connects all of the different components together. It includes the CPU, RAM, storage, and other components such as the keyboard, mouse, and monitor.

The power supply unit (PSU) converts the AC power from the wall outlet into DC power that the computer components can use.
Input/output devices are used to interact with the computer. Examples include the keyboard and mouse for input and the monitor for output.

When you give a command to the computer, the command is passed through the input device (such as a keyboard), then to the CPU, which retrieves the instruction from memory and performs the necessary calculations. The results of these calculations are then passed back to the memory and ultimately displayed on the output device (such as a monitor).

Additionally, computers have many other internal and external components like Graphic cards, sound cards, Network cards, USB ports, CD/DVD drives, etc that help to enhance the performance of the computer and also to connect it with other external devices.

The computer also uses a system bus to connect the various components and allow them to communicate with each other. The system bus is a set of communication pathways that connect the CPU, memory, and other components.

In addition to the basic components mentioned earlier, there are also many other peripheral devices that can be connected to a computer. These include printers, scanners, cameras, and external hard drives. These devices can be connected through USB ports, FireWire ports, or other types of connectors.

The computer also uses a cooling system to keep the internal components from overheating. The cooling system may include fans, heat sinks, and other components that help to dissipate heat.

Finally, the computer also includes firmware, which is a type of low-level software that helps to control the basic functions of the hardware. This includes the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) which is responsible for starting the computer and providing basic input/output functions before the operating system is loaded.

In summary, computers are complex machines that use a combination of hardware and software to perform a wide range of tasks. The different components work together to retrieve and process data and display the results on the output device. The operating system and software applications provide the interface between the user and the computer’s hardware, allowing users to perform tasks such as word processing, web browsing, and gaming.

The market value of computers.

The market value of a computer can vary greatly depending on a number of factors, including the brand, model, age, and condition of the computer.
