Hardware of the personal computer

Beginners who are not yet familiar with the computer are interested in learning more about what PC hardware is, what is meant by it.

First of all, let's start by enumerating the main elements of the computer. This is a system unit, keyboard, monitor and mouse. The most important is the system unit. Let's consider it in more detail. Inside it is the motherboard, which connects all the details of the computer. The processor is the brain of the computer. In the system unit, the fan closes it. Also there is a RAM - it affects the speed of the computer, but it is short-lived. The video card is responsible for displaying the image on the monitor. In addition, the hardware includes a sound card that is responsible for the sound; The hard drive on which the operating system is installed, and it stores information. The system unit also houses a DVD drive that plays audio and video discs, computer games.

All the details of the system unit are attached to the motherboard using wires. When installing a DVD-drive or hard disk, you can be mistaken, because they are both attached to the same SATA-connectors. One hard drive is connected to the motherboard in a socket with a SATA 0 signature.

The hardware of the computer includes, as mentioned above, except the system unit monitor, which is the main output device. Modern monitors are produced on liquid crystals, from where the popular reduction of LCD appeared. They use active matrix, which is a transparent screen made up of thin-film transistors. Each separate cell of the monitor (pixel) is controlled by its transistor and creates a point on the screen, which sets the color and brightness.

Choosing the hardware for the computer, it is important to know what characteristics of the monitor are worth paying attention to, since it affects the brightness of color and comfort for the eyes. First of all, it is necessary to determine for what purpose the monitor is intended. So, if you work with graphic editors, you will need a device with high-quality color rendering, a large diagonal and wide settings. For computer games, too, the screen size, fast response and high contrast matter. If you do not pursue specific goals and you need an everyday home monitor, then it's better to choose a large screen and a beautiful case.

An urgent need for all computer owners is access to the Internet, which also requires special devices. The hardware of computer networks includes the following. Computer-server, which, having high performance, provides constant access to its information resources, being connected to uninterrupted power supply and connected to the network. A home computer that is connected to the Internet is the terminal through which we access the resources of the network.

To access the Internet, you need a modem - a device that converts information from a discrete digital to an analog form. It allows you to translate the physical form of information from the standard used in computers to the telephone, and vice versa. Earlier, dial-up modems provided a sufficiently low speed with which data was transmitted. With the advent of DSL modems, the speed of information transfer over a dedicated Internet channel has become dependent only on the tariff plan and the provider. In addition to the modem, an additional network card is needed to access the Internet, which is a peripheral device that allows the computer to interact with other devices connected to the network.

The proposed material, I hope, helped you to study the hardware of the computer, and not be lost with the choice of accessories in electronics stores.
