Although computers are already widespread, most people are white for basic computer hardware. The lack of knowledge of computer hardware has led many people to turn around when choosing computers. If you don't know where to start, this text gives you all the basic computer knowledge that you may not need, but you must know。
A book that gives you all the basics of computers
The first thing we understand is that computers are made up of two parts of software and hardware, one of which is impossible. In short, software consists mainly of winxp, win7, win8, win10 and win11 software systems. The xp is the oldest software system, and there are some old computers in use. We use software systems win7, win8, win10, win11。
The second is the hardware composition of computers. That is, the hardware configuration that the computer focuses on, and if the basic knowledge of the hardware configuration is not familiar, the white part of the computer is the only part that gets trapped when choosing the computer。
The hardware system consists mainly of the main board, cpu, graphic cards, etc
In short, the hardware system consists mainly of the main plate, cpu, graphic cards, hard disks, five large contents of the memory, as well as boxes, power, pv, acoustic cards, webcards, monitors, keyboards, mouse, etc., which are essential external attachments。
Usually, we can see that the boxes are equipped with cpus, main plates, cpu fans, memory, graphic cards, hard drives, power, etc., which are the most basic parts of our case. Inside the case, a large board was installed with a wide variety of electrical circuits. It's the main board of our entire computer's nervous system。
One of the main nervous panels of the entire computer
Important hardware, such as cpu, memory, graphic cards, sound cards, etc., are clearly visible on the main board and are installed directly on the main board. And hard drives, power, dvds, etc., need to be connected to the main panel by connecting lines, and we usually put them in a box that we call the computer host, which is the main component of the computer。
The cpu, as a central processor, is the most important hardware configuration for computer selection, the most important hardware of all hardware, and the preferred hardware configuration option. Usually, as we can see, it's directly under the cpu fan on the main panel. Cpu is equivalent to the entire computer's brain, which supports all the calculations in the computer。
Cpu is equivalent to a brain in a computer
Again, memory, i. E., memory strips on the main panel, refers to internal memory that cpu can read directly, mainly in the form of chips. In short, memory bars are computer hard drives to the cpu transit station, which is equivalent to a bridge. It is also the cache of temporary data received from computer systems, and data exchanged with external repositories such as hard drives, which are normally used in programs such as games, typing software, which can be used only if transferred to memory。
The graphic cards are important originals for connecting monitors and computer hosts, mainly integrated and independent cards. Independent graphic cards are placed on a slot on the main panel, and integrated graphic cards are generally integrated in cpu or on the main panel, or are commonly referred to as built-in nuclear core graphic cards。
Independent graphic cards perform better than core graphic cards
Under normal circumstances, independent graphic cards perform better than core graphic cards, but are expensive at prices. The core of the built-in core graphic card is the gpu, which is now known to be integrated above the cpu. If it's a collection in the main board, it's basically the old board。
Again, the hard drives are divided into mechanical hard drives and solid hard drives, which are one of the external storage units of computers. At present, in the computer hardware market, solid hard drives are the dominant choice for computer machines. Solid-state hard drives run faster than mechanical hard drives and solid hard drives perform better than mechanical hard drives. But the greatest advantage of a mechanical hard drive is that it has a good data storage capacity and is cheap。
Solid-state hard drives are the main choice for a computer
Power is the most important external component of the computer. The function of a computer power source is to convert 220 volts of domestic electricity into one of the voltages required for various components of the computer, such as cpu's working voltage, which is usually only a few. For safety reasons, we usually load all the parts of the computer in the mainframe。
Under normal circumstances, there are two lights on the computer case, one of which is a power light, which is lit when it is turned on. Another signlight, which sometimes blinks, is our hard drive light. And when the light flashes, it represents our hard drive, and it's also a sign to determine whether the computer is functioning properly。
Basic computer composition
In general, these are the basic components of computers. Just to sum up the basic knowledge of these hardware, there is no need to be manipulated when choosing computers。
