Novice users who are not yet familiar with the computer are interested in learning more about what PC hardware is and what is meant by it.
First of all, let's start by listing the basic elements of a computer. This is a system unit, keyboard, monitor and mouse. The most basic is the system unit. Let's consider it in more detail. Inside it is a motherboard that interconnects all the details of a computer. The processor is the "brain" of the computer. In the system unit it is closed by a fan. There is also RAM - the speed of the computer depends on it , 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. A DVD drive is also located in the system unit, which plays audio and video discs and computer games.
All parts of the system unit are attached to the motherboard using wires. When you install a DVD-drive or hard drive, you can make a mistake, because both of them are attached to the same SATA-connectors. One hard drive connects to the motherboard in a SATA 0 signed port.
The computer hardware includes, as mentioned above, in addition to the system unit, a monitor, which is the main device for outputting information. Modern monitors are available on liquid crystals, from which came the popular abbreviation LCD. They use active matrices, which are a transparent screen consisting of thin-film transistors. Each individual cell of the monitor (pixel) is controlled by its transistor and creates a point on the screen, which sets the color and brightness.
When choosing hardware for a computer, it is important to know what characteristics of the monitor you should pay attention to, since the color rendering brightness and eye comfort depend on it. First of all, it is worth deciding what purpose the monitor is intended for. So, if you work with graphic editors, you will need a device with high-quality color reproduction, a large diagonal and wide settings. For computer games, screen size, fast response and high contrast also matter. If you do not pursue specific goals and you need an everyday home monitor, then it is better to choose a large screen and a beautiful case.
An urgent need for all owners of computers is access to the Internet, which also requires special devices. The hardware of computer networks includes the following. A 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 network resources.
To access the Internet you need a modem - a device that converts information from discrete digital to analog form. It allows you to translate the physical form of information from the standard used in computers, into the telephone, and vice versa. Earlier, dial-up modems provided a fairly low speed with which data was transmitted. With the advent of DSL modems, the speed of information transfer over a dedicated Internet channel began to depend only on the tariff plan and provider. In addition to the modem, to access the Internet, you also need a network card, 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 study the computer hardware, and not get lost with the choice of components in electronics stores.
