This is how your computer works
No. The box you have on the floor is not called the hard drive. It is a computer chassis containing several different computer parts. The hard drive is one of those computer parts.
Laptop or desktop computer
Whether your computer is portable or desktop, it contains computer parts that work according to the same principle. For reasons of space, the parts of a laptop are adapted to be as compact as possible. Instead of a desktop computer, you can take advantage of the space and take advantage of opportunities for better cooling of the parts. They can then also perform a little better.
The computer processor can be likened to the computer’s brain. It is the processor that does all the calculations, ie the thinking in the computer. The processor is sometimes also called CPU, which is an abbreviation of the Central Processing Unit.
The memory of the computer is also sometimes called working memory, or RAM. RAM is the abbreviation that stands for Random Access Memory. The information is completely cleared when the computer becomes powerless.
The motherboard can be likened to the computer’s nervous system. It is the motherboard that ensures that all parts of the computer can collaborate and communicate with each other. The motherboard is also often the limit if you want to upgrade your computer later. Maybe it does not support new technology that came later.
The hard drive is a type of fixed memory in the computer. Information stored here should be left after you shut down your computer. The hard drive can also be used by, for example, Windows to store information to be processed by the processor later.
Hard drives are available with different technologies. The most common are still mechanical hard drives that have magnetic discs that rotate at an incredible speed. However, solid-state drive SSDs, Solid State Drive, are starting to become more common as prices fall. SSD has no moving parts which make them more resistant to impact. The information can also be handled faster than on a mechanical hard drive.
There must be a graphics circuit in the computer. However, there is not always a loose graphics card. The graphics circuits may be integrated on the motherboard or processor instead. For computer gaming or other graphics-heavy tasks, however, it is a prerequisite with a dedicated graphics card.
The graphics card has its own processor and memory. The graphics card processor is sometimes called the GPU, which is an abbreviation of the Graphics Processing Unit. The graphics card helps to relieve the computer processor by taking care of all graphical calculations.
The parts of the computer must be powered to work. The parts of the computer normally want 5v or 12v. 7v may also occur in some contexts. The power supply converts the electricity from the electrical outlet in your home to the right current and voltage.
The power supplies have in their specification how many watts they can deliver. Most often, the graphics card consumes the most power. It is important then that you have a power supply that is adapted to the parts you have on your computer.
The chassis is the box in which all the parts are mounted. All computer parts have different standards in a format so that they will fit in a chassis that meets these. A computer chassis can look different and is available in several different models. Desktop, which is supposed to be on a desk, or Tower – which is supposed to be placed at any place, are the most common models.
A chassis is more than just a box and can be unique in several ways. There are those that have extra equipment, LEDs, visual design and so on. There are also those that are specially adapted for more efficient cooling of the computer parts and / or to attenuate as much fan noise as possible.
How a computer works
How does a computer work? Yes, that question, unfortunately, has a long answer. Here I have reproduced the short answer. Each part of your computer has unique tasks and cooperates with the other parts depending on the task.
In the past, they often talked about clock frequency on the computer processor as a measure of performance. This is no longer a comparable measure. The clock frequency tells you how many clock cycles a processor can make per second.
A processor with 2.0 GHz clock frequency means it can do 2 billion clock cycles per second. What is important today is how much can be handled in each clock cycle.
To be able to compare reasonably, manufacturers have started with different market names on their processors. Higher numbers are generally better. Another specification worth looking at is L2 or L3 cache size. As the graphics attempt to describe above, the L2 / L3 cache is critical to the performance of the computer.
The L2 / L3 cache is the place where the processor very temporarily stores what is to be handled in the coming cycles. The more it can store there, the more rarely it needs to go out and ask the tough RAM for information. However, cache in the processor is very expensive and affects the price of the processor. Therefore, it is more common to stick to a normal size and increase the amount of RAM instead. There are also RAMs with different speeds.
How does a computer work?
I hope you can answer that after reading this. All computers work on the same principle as mentioned here.
