Understanding the parts of the computer

To fully understand how to assemble a computer or notebook, it is essential to know the parts that make up a computer system. Each component has a specific function that contributes to the overall performance of the system. Here are the main parts of a computer.

1. Motherboard

The motherboard is the main circuit board in a computer. It is the foundation on which all other components are connected and communicate. The motherboard is also responsible for distributing power to system components and contains expansion slots for adding or upgrading components such as RAM or graphics card.

2. Processor (CPU)

The processor, or CPU (Central Processing Unit), is the brain of the computer. It performs all the instructions and calculations necessary for the computer to function. Processor speed, measured in gigahertz (GHz), determines how fast it can process data. A faster processor can execute more instructions in less time, resulting in faster computer performance.

3. RAM Memory

Random access memory, or RAM, is the computer's short-term memory. It temporarily stores data that the processor needs to access quickly. The more RAM a computer has, the more data it can process simultaneously, which can significantly improve performance in tasks like multitasking and gaming.

4. Hard Disk/SSD

The hard disk or SSD (Solid State Drive) is the computer's long-term memory. It stores all the data and information including the operating system, programs and files. SSDs are faster than traditional hard drives as they have no moving parts and access data electronically rather than physically.

5. Video card

The video card, also known as GPU (Graphics Processing Unit), is responsible for rendering images and videos on the computer screen. For graphics-intensive games and applications, a powerful graphics card is essential. Some CPUs have integrated graphics, which may be sufficient for basic tasks, but for superior graphics performance, a dedicated graphics card is required.

6. Power Supply

The power supply supplies power to all computer components. It converts power from the outlet into a form the computer can use. Required power varies depending on system components. Insufficient power supply may lead to unstable performance or damage components.

7. Cabinet

The computer case houses all of the system components. It provides protection against dust and physical damage, and helps with ventilation to keep components cool. The case also contains bays for installing hard drives, SSDs, and optical drives such as a DVD drive.

Understanding these parts of the computer is the first step in building your own system. With this knowledge, you can select components that meet your needs and budget, and you will have the confidence to build the system yourself. Remember, practice makes perfect, so don't give up if things seem difficult at first. In time, you will become an expert at computer assembly.
