The cooler is equipped with four legs, which we will install in the holes located near the corners of the motherboard socket. The cooler must be installed so that all four legs are installed in the holes of the motherboard. Now you need to fix the cooler on the motherboard, to do this, alternately press each switch down with your finger. When you press a leg with your finger, when you hear a click, then this leg will be fixed to the motherboard, and so you will need to do this with all four legs. After you have done everything, make sure that the cooler is firmly seated in the motherboard socket. For the cooler to be securely fixed to the motherboard socket, the switch on the cooler must be in the closed position. If the switch is in the open position, then the leg can easily come out of the motherboard. Now we just need to connect the power from the cooler to the CPU_FAN connector on the motherboard.

Slide 2

What does the term "computer configuration" mean?

A COMPUTER CONFIGURATION is its composition or a set of hardware and software. HARDWARE CONFIGURATION are devices that are part of a computer. SOFTWARE CONFIGURATION, as you probably guessed, these are the programs that you have installed on your computer. Different people need different hardware and software configurations.

Slide 3

External and internal devices

Computer devices that are located outside are called EXTERNAL. And those devices that are inside the computer are called INTERNAL. EXTERNAL DEVICES are used to receive and issue information. Information storage and processing devices are trying to be made INTERNAL, they are "hidden" inside the case so that it is more difficult to get there. Now we will get acquainted only with EXTERNAL DEVICES. They are on the table and we can touch them with our hands. Different computers may have different external devices, but there are four that each computer has. These are the system unit, monitor, keyboard and mouse.

Slide 4

System unit

This is the most important unit of the computer. It contains devices for storing and processing information. On the rear wall of this unit there are several connectors for connecting external devices, and on the front there are buttons for turning on and switching the system unit. It also contains disk drives. Disk drives are devices that you can insert floppy disks and laser disks into. Signals are recorded on discs.

Slide 5

Monitor

A monitor is a lot like a TV, only it has much better picture quality. Do not watch TV close, as this can hurt your eyes. You can look at the monitor at arm's length. Monitors can be color and monochrome (they are called monochrome). You guessed it that the monitor is used to display information. It can usually display texts, numbers, pictures and videos on the screen.

Slide 6

Keyboard

Use the computer keyboard to enter letters, numbers, and punctuation marks. It has over 100 keys, each with its own purpose. Keys can be divided into blocks: alphanumeric, functional, additional and cursor. The great-grandmother of the computer keyboard was a typewriter.

Slide 7

Mouse

A mouse is also a device for entering information into a computer. It has two or three buttons, so it is inconvenient to enter letters and numbers with it. But with its help signals are easily entered. The mouse can be rolled on a table or on a special rug. When we roll it to the left, the computer receives a signal to move the mouse pointer to the left on the screen as well.

Slide 9

What is a scanner and why is it needed?

A SCANNER is an external device that is designed to enter text or pictures into a computer. The data entered into the computer using the scanner is recorded in a graphic format. In addition, today there are special programs that can recognize the scanned text, i.e. write it down in text format. An artist definitely needs a computer and a SCANNER. With the help of a scanner, he can enter into a computer an old yellowed photograph, Then, using a graphic editor, restore it and print it on a printer.

Slide 11

What is a printer and what is it for?

A PRINTER is an external device that can be used to print text or pictures created on a computer onto paper. Modern printers can print photographic quality pictures, but this requires special paper. A writer definitely needs a computer and a PRINTER. With the help of a computer, he can write down the invented chapters of a new story, and with the help of a printer, print them and give them to be read to a friend who does not have a computer.

Slide 12

Sound card and headphones

In order for the computer to be able to work with music, sound and speech, it needs a special sound card, which is called a SOUND CARD.

Slide 13

What is a modem and what is it for?

If you have a phone and a computer at home, then thanks to MODEM you can connect to the worldwide computer network and receive information from millions of computers from all over the world. MODEM converts data stored in a computer into telephone signals, and vice versa, telephone signals into data. MODEM computers communicate with other computers, no matter how far away they are, even on another continent. With the help of MODEM, you get access to a variety of information (news, books in the library, private announcements), you can buy the product you like in the online store or order a service at home. A writer, artist and composer must have access to the INTERNET. Then they will be able to exchange sound, text and graphic files without leaving home.

Slide 14

What is a multimedia computer?

If a computer can work with five types of information (numerical, text, graphic, sound, video), then it is called MULTIMEDIA. And a disc that contains such types of information is called a MULTIMEDIA DISC.

The work can be used to conduct lessons and reports on the subject "Informatics"

The section "Presentations in Informatics" has collected ready-made presentations on almost all topics that are held in schools and universities in informatics lessons. In this section of the site you can download ready-made presentations on computer science. A presentation on the topic of computer science can be used both in the classroom and in the classroom on information technology.

So, what does our ordinary personal computer (PC), which we use at home or at work, consist of? Consider its hardware ("hardware"): Consider its hardware ("hardware"):

System unit The system unit in the computer is the "master" unit. If you carefully unscrew the screws from its back wall, remove the side panel and look inside, then only in appearance its structure will seem complicated. Now I will briefly describe its structure, and then I will characterize the main elements in the most understandable language. The system unit in the computer is the "master" one. If you carefully unscrew the screws from its back wall, remove the side panel and look inside, then only in appearance its structure will seem complicated.

Peripherals 1. The computer keyboard consists of 6 key groups: 1. Alphanumeric; 2. Controllers (Enter, Backspace, Ctrl, Alt, Shift, Tab, Esc, Caps Lock, Num Lock, Scroll Lock, Pause, Print Screen); 3. Functional (F1-F12); 4. Numeric keypad; 5. Cursor control (->, ,">

Mouse Mouse Mouse (mechanical, optical). Most programs use two of the three mouse keys. The left key is the main one, it is controlled by the computer. It plays the role of the Enter key. The function of the right button depends on the program. In the middle there is a scroll wheel, which you quickly get used to. Mouse (mechanical, optical).

The scanner automatically reads from paper carriers and enters into the PC any printed texts and images. The microphone is used to input sound into the computer. The scanner automatically reads from paper carriers and enters into the PC any printed texts and images. The microphone is used to input sound into the computer. The monitor (display) is designed to display information on the screen. Most often in modern PCs, SVGA monitors are used with a resolution (the number of dots located horizontally and vertically on the monitor screen) 800 * 600, 1024 * 768, 1280 * 1024, 1600 * 1200 with up to 16.8 million colors.

The printer is designed to print text and graphics. There are dot matrix, inkjet and laser printers. In dot matrix printers, the image is formed from dots in an impact manner. Inkjet printers in the print head instead of needles have thin nozzle tubes through which the smallest droplets of ink are ejected onto the paper. Inkjet printers also perform color printing by mixing base colors. The advantage is high print quality, the disadvantage is the danger of ink drying, the high cost of consumables.
