we will try to answer one very simple and at the same time a very difficult question: how to choose a CPU?
Whether you are upgrading your computer or planning to build a new PC, the choice of processor will be one of the most important.
For example, higher clock speeds, the number of cores can seriously affect overall performance, a faster system, more comfortable gameplay, as well as processor-dependent applications related to video editing and rendering.
CPU Cache is important. Without it, from the high processor clock speed, there would be no use. The cache allows you to use any, even the “slowest” RAM on your computer, without noticeable damage to its performance.
Computer processors have made a significant breakthrough in development over the past few years. The size of transistors decreases every year, and productivity is growing. At the same time, Moore’s law is already becoming irrelevant. As for the performance of processors, it should be taken into account, not only the number of transistors and frequency, but also the cache volume.
You may have already heard about the memory cache when you were looking for processor information. But, usually, we do not pay much attention to these numbers, they do not even stand out much in advertising processors. Let’s look at what the processor cache effects, what types of cache are and how it all works.
Solving any task, the computer processor receives from the RAM the necessary blocks of information. Having processed them, it writes the results of calculations into memory and receives the following blocks for processing. This continues until the task is completed.
All mentioned operations are performed at a very high speed. However, even the fastest RAM is slower than any “leisurely” processor. Each reading of information from it and writing it back is time consuming. On average, the speed of RAM is 16 – 17 times lower than the processor speed.
The motherboard (MP) is a complex multilayer printed circuit board, which is the basis of the computer (PC). All other components are connected to the motherboard, and, in fact, it is a kind of connecting link for all other devices in the PC. choosing the right motherboard should be approached as seriously and responsibly as possible because the performance, stability, and durability of the entire system will depend on this choice. In addition, it is not recommended to install powerful high-performance components in a budget motherboard, since the MP may simply not overpower them in terms of power, and the opposite situation is not recommended – buy an expensive high-performance motherboard and install budget components in it. In this case, the expensive MP simply does not justify its purchase.
It is useless to buy a powerful processor and crazy gigabytes of RAM if you have a weak motherboard. Instead of supporting the work of all the components of the PC, it will simply clamp them in the tight framework of its inconsistency. And this means that you will have to select a new board that will allow the computer to fully reveal its capabilities.
Most computer users are unlikely to be able to use the capabilities of their computer without a device such as a computer mouse, because it is much easier to do work and play computer games with it. Of course, the question of what a computer mouse is is not of concern to many, because everything is clear, but not everyone knows about the types of computer mice and their differences.
Today we’ll talk about what is keyboard, what keys it consists of, what they are called, computer keyboard keys and their functions into which groups are divided and where they are located and types of computer keyboard
You will learn what hotkeys exist in windows 7 and windows 10. Learn how to assign keys yourself using the operating system and a special program. I will answer the most frequently asked questions from beginners.
