For generations who didn’t grow up with computers, they can often seem overwhelming to tackle. But don’t be too intimidated. Even the generations that grew up with computers don’t always have a lot of knowledge about how these machines work or what their various parts do. Here’s a quick guide to help demystify the basic components and functions of a personal computer.
While there are different types of computers designed for business and other purposes, what you probably think of as a “computer” is a personal computer, or PC, designed for consumer use, such as a desktop or desktop computer. laptop.
All computers have hardware and software. Hardware is any component of a computer that has a physical structure, such as internal parts or a keyboard. Software is a program with instructions that tell the hardware what to do to perform certain functions, such as editing a text document, sending an email, or uploading a photo. .
Most computers come with the same basic hardware. The computer case (sometimes called a computer tower) contains all of the major components.
Computers have a central printed circuit board called motherboard. In a way, the motherboard is like the circulatory system of the computer. It serves as a place to transfer power and connect computer components. Without the motherboard, nothing else would work.
A computer central processing unit, or CPU, acts like the brain. It processes the language of instructions received from programs, called code. You’ve probably seen an Intel sticker on your computer. Intel is one of the many manufacturers of central processing units. The central processing unit may relate to what is colloquially called a “computer chip”. Each motherboard has a designated socket in which the central processing unit fits perfectly.
The graphics processing units, GPU, is what makes it easy to create images on a computer screen. This makes it an important component for PC users who edit videos, create graphics, or play video games. Graphics processing units come with or are “built-in” into most computer central processing units. Consumers can also purchase a separate graphics card or video card, which acts as an extension of the computer’s ability to process images. It comes with a more powerful graphics processing unit and almost looks like a smaller second motherboard.
RAM, or RAM, comes in the form of thin sticks that plug into the motherboard and is a big factor in your PC’s overall performance. It provides running applications with a location to store and access data, functioning as short-term memory.
Larger amounts of RAM allow computers to multitask, such as keeping multiple Internet browser tabs open while you open a document and stream music. The more RAM there is, the more your computer can do at once.
Storage room comes in various forms, usually as Hard disk or hard drive, or Hard disk or SSD. These are usually simply called Hard disk. Like long-term memory, it stores permanent data, such as text documents, photos, programs, files, and the operating system. It is common to also have external hard drives that plug into a computer for additional storage.
Computers Power supply, or PSU, is what transfers power from an outlet to the motherboard and other internal components. The various components of a power supply are housed in a metal frame with a fan attached to keep it cool during operation.
Of course, you can’t use a computer without external parts such as the monitor or screen, keyboard and mouse, or trackpad on a laptop.
While computers may seem like technological magic that is difficult to understand (and to some extent they are), at the end of the day, they are just machines made of various parts. Knowing these parts makes it much easier to understand how a computer works.
