НУЖЕН ПЕРЕВОД ТЕКСТА. СРОЧНОInput devices are the pieces of hardware which allow us to enter information into the computer. The most common are the keyboard and the mouse. We can also interact with a computer by using one of these: a lightpen, a scanner, a trackball, a graphics tablet, a joystick or a voice recognition device.The computer keyboard is an electronic device with keys arranged like earlier typewriter keyboards but with extra keys. They perform different functions. The computer mouse is a hand-operated device that lets you control more easily the location of the pointer on your screen. You can make selections and choices with the mouse button. A lightpen is a highly sensitive photo-electric device which uses the CRT (Cathode Ray Tube) screen as the positioning reference. The user can pass the pen over the surface of the screen to detect, draw or modify images displayed on the screen. A scanner is an input device that scans (reads) the image as a series of dots and introduces the information into the computer memory. A trackball is a stationary device that works like a mouse turned upside down. The ball spins freely to control the movement of the cursor on the screen. A graphics tablet is an input device which allows the user to specify a position on the screen by using a stylus. Tablets are more accurate than other devices. A joystick is an input device with a vertical level used in computer games to move the cursor around the screen. Voice recognition devices allow computers to listen to your voice and change what you say into a written message or into orders.The monitor The characters and pictures that we see on the screen are made up of dots, also called picture elements (pixels). The total number of pixels in which the display is divided both horizontally and verticailv is known as the resolution. If the number of pixels is very large, we obtain a high resolution display and therefore a sharp image. If the number of pixels is small, a low resolution is produced. Typical resolutions are 640 x 480 or 1,024 x 768 pixels. Pixel density affects the image: a larger number of pixels gives a much clearer image.The cathode ray tube of the monitor is very similar to that of a TV set. Inside the tube there is an electron beam which scans the screen and turns on or off the pixels that make up the image. The beam begins in the top left corner, and scans the screen from left to right in a continuous sequence, similar to the movement of our eyes when we read, but much faster. This sequence is repeated 50, 70 or 85 times per second, depending on the system. If the rate of this repetition is low, we can perceive a flickering, unsteady screen, which can cause eye fatigue. However, a fast-moving 75 Hz 'refresh rate' eliminates this annoying flicker.What we see on the screen is created and stored in an area of RAM, so that there is a so memory cell allocated to each pixel. This type of display is called bit-mapped. On monochrome monitors, bits 0 are visualized as white dots, and bits 1 as black dots.
