SETTING THE PURPOSE OF THE LESSON FOR THE STUDENTS

Blitz survey on the main set of the computer:

a printer printing device. Carries out the output from the computer of encoded information in the form of hard copies of text or graphics.

There are thousands of printer names. But there are three main types of printers: dot matrix, laser and inkjet.

Dot matrix printers use combinations of small pins that hit the ink ribbon so that the character is imprinted on the paper. Each character printed on the printer is formed from a set of 9, 18 or 24 needles, formed in a vertical column. The disadvantages of these inexpensive printers are their noisy operation and poor print quality.

Laser printers work in much the same way as photocopiers. The computer forms in its memory a “image” of a page of text and transfers it to the printer. Page information is projected using a laser beam onto a rotating drum with a light-sensitive coating that changes its electrical properties depending on the illumination.

After exposure to the drum, which is under electrical voltage, a coloring powder is applied. toner with particles adhering to the highlights on the drum surface. The printer uses a special hot roller to pull the paper under the drum; toner is transferred to the paper and “fused” into it, leaving a long-lasting, high-quality image. Color laser printers are still very expensive.

Inkjet printers generate characters as a series of ink dots. The print head of the printer has tiny nozzles through which quick-drying ink is sprayed onto the page. These printers are demanding on paper quality. Color inkjet printers create colors by combining inks in the four primary colors. vivid cyan, magenta, yellow, and black.

The printer is connected to the computer through a printer cable, one end of which is inserted with its connector into the socket of the printer, and the other. into the printer port of the computer. Port. this is a connector through which you can connect a computer processor with an external device.

Each printer must have its own driver. a program that is capable of translating (translating) standard computer print commands into special commands required for each printer.

Scanner. a device for inputting graphic images into a computer. Creates a digitized image of a document and places it in computer memory.

If printers output information from a computer, then scanners, on the contrary, transfer information from paper documents to computer memory. There are hand-held scanners that roll over the surface of the document by hand, and flatbed scanners that look like copiers.

If text is entered using a scanner, the computer interprets it as a picture, not as a sequence of characters. To convert such graphic text into a conventional character format, optical image recognition programs are used.

Modem a device for transmitting computer data over long distances via telephone lines. The digital signals generated by the computer cannot be directly transmitted over the telephone network because it is designed to carry human speech.

The modem converts digital signals from the computer into alternating current of the audio frequency range. this process is called modulation, and also the inverse transformation, which is called demodulation. Hence the name of the device: modem. modulator / demodulator.

Joystick. usually it is a rod-handle, the deviation of which from the vertical position leads to the movement of the cursor in the corresponding direction on the monitor screen. It is often used in computer games. Some models have a pressure sensor mounted in the joystick. In this case, the harder the user presses on the handle, the faster the cursor moves across the display screen.

Trackball. a small box with a ball embedded in the top of the case. The user rotates the ball by hand and moves the cursor accordingly. Unlike a mouse, the trackball does not require free space around the computer, it can be built into the car body.

Digitizer a device for converting finished images (drawings, maps) into digital form. It is a flat panel. a tablet placed on a table and a special tool. pen that indicates the position on the tablet. When you move the pen across the tablet, its coordinates are fixed at closely spaced points, which are then converted in the computer into the required units of measurement.

Plotter (plotter). a device that draws graphs, pictures, or diagrams under computer control.

Plotters are used to obtain complex design drawings, architectural plans, geographical and meteorological maps, and business diagrams. Plotters draw images with a pen.

Roller plotters move the paper under the pen, and flatbed plotters move the pen across the entire surface of the horizontal paper.

A plotter, just like a printer, definitely needs a special program.driver, allowing application programs to transmit instructions to it: raise and lower the pen, draw a line of a given thickness, etc.

Floppy disk (eng, floppy disk), or floppy disk,

information, which is a flexible plastic disk in a protective shell, is used to transfer data from one computer to another and to distribute software.

The diskette consists of a round polymeric substrate coated on both sides with magnetic oxide and placed in a plastic bag, on the inner surface of which a cleaning coating is applied. The package has radial slots on both sides through which the read / write heads of the drive access the disk.

Hard disk drive (English HDD. Hard Disk Drive) or ctj hard drive. it is the most widespread mass storage device of large capacity, in which information carriers are round aluminum plates. platters, both surfaces of which are coated with a layer of magnetic material. Used for permanent storage of information. programs and data.

Like a floppy disk, the working surfaces of the platters are divided into circular concentric tracks, and the tracks are. into sectors. The read / write heads, together with their carrier structure and disks, are enclosed in a hermetically sealed enclosure called a data module. When a data module is inserted into the drive, it automatically connects to the system that supplies cleaned, cooled air. The surface of the platter is magnetically coated with a thickness of only 1.1 microns, as well as a layer of lubricant to protect the head from damage when lowering and lifting on the go. When the platter rotates, an air layer forms above it, which provides an air cushion for the head to hang at a height of 0.5 microns above the disk surface.

Winchester drives have a very large capacity: from 10 to 100 GB. In modern models, the spindle (rotating shaft) rotation speed is usually 7200 rpm, the average data retrieval time is 9 ms, the average data transfer rate is up to 60 MB / s. Unlike a floppy disk, a hard disk spins continuously. All modern drives are equipped with a built-in cache (usually 2 MB), which significantly improves their performance. The Winchester drive is connected to the processor through the hard disk controller.

To work with a CD-ROM, you must connect a CD-ROM drive to your computer, which converts the sequence of grooves and ridges on the surface of the CD-ROM into a sequence of binary signals. For this, a reading head with a microlaser and an LED is used. The depth of the depressions on the surface of the disk is equal to a quarter of the wavelength of the laser light. If, in two successive cycles of information reading, the light beam of the laser head passes from the protrusion to the bottom of the cavity or vice versa, the difference in the lengths of the light paths in these cycles changes by half a wave, which causes an increase or decrease in the direct and reflected light from the disk that are incident on the LED.

Almost all personal computers today have a CD-ROM drive. But many interactive multimedia programs are too large to fit on a single CD. CD-ROM technology is rapidly being replaced by digital video DVD technology. These discs are the same size as regular CDs, but can hold up to 17GB of data, i.e. replaces 20 standard CD-ROMs in volume. On such discs, multimedia games and interactive videos of excellent quality are released, allowing the viewer to view episodes from different camera angles, choose different options for the end of the picture, get acquainted with the biographies of the actors who have starred, and enjoy excellent sound quality.

Recorder CDR (Compact Disk Recordable) is able, along with reading ordinary CDs, to record information on special optical disks with a capacity of 650 MB.

Storage device WARM (Write And Read Many times), allows multiple writing and reading.

Tape Drives (Streamers) and Removable Disk Drives

Streamer (eng, tape streamer). a device for backing up large amounts of information. As a medium, cassettes with magnetic tape with a capacity of 1-2 GB and more are used here.

Streamers allow a huge amount of information to be recorded onto a small cassette tape. The hardware compression tools built into the streamer allow you to automatically compress information before writing it and restore it after reading it, which increases the amount of stored information.

The disadvantage of streamers is their relatively low speed of writing, searching and reading information.

Recently, removable disk drives are increasingly used, which allow not only increasing the amount of stored information, but also transferring information between computers. The volume of removable disks. from hundreds of MB to several Gigabytes.
