How mechanical mouse works?
Mouse allows quick and easy access to many icons and operations on the computer, such as selecting from a list of possible actions (menu), work with Windows and moving files. when you move the mouse, the rubber ball turns and runs two rollers, both associated with wheel with slots. light-emitting diode (LED) sends light through the slits and transducers convert light into an electrical signal. Pressing the button will send additional information to the computer.
1. Roller - Roller turns by turning the rubber ball back and forth
2. Rubber Ball - The ball is turning when you run the mouse over the surface
3. Moving Roller
4. Slotted wheel - This wheel with the slots associated with vertical rollers.
5. Light emitting diode
6. Converter
7. Cable coupling
8. Plastic housing
9. Cable - cable connects the mouse to the computer through input on your computer
10. Chip - The chip processes data from the transducer movement and buttons before it transmitt them to computer
11. Right button - The button pressing their work to encourage the chip and the chip sends signals to the computer
12. Roller - This is moved by rotation of Roller balls
1. Wheel with slots - when the wheel rotates, the movement of the slot next to the diode produces light flashes
2. Light-emitting diode (LED) - LED sends light through the slits on the outer edge of the wheel
3. Converter - Converter code flashes of light into electrical signals.
4. Roller Lever - Lever roller transfers spins on the wheel with slits.

How hard disc works?
The area of data storage is a set of flat plates coated with magnetized lining.Data is stored as a series of coordinated magnetized area inside lining, called "domains". To read the data or write, a device called an executive device moves heads to read or write to position, vertical compared to the disk, while the plates spinning at high speed. Then, the signals are sent to the head, or the head receives signal, which records or reads data.
1.FAT - in one part of the disc, in space to store files, information about the location of all files on the disk are stored.
2.Head "write-read" - Head reads and writes data hovering 0.002 mm above the plate surface
3.Lever of executive devices - Each head is "read-write" device placed on the light handle that rotates around the pin at one end and runs heads harmonized
4.Data cable - Trough this cable data flow between the hard disk, and devices that we call the "Master Disc". This device manages plates spins and data flow between the heads, "read-write" and the opposite of it and the executive devices.
5.Block devices executive - executive device receives a continuous flow of instructions to run the "read-write" heads.It can start running heads up to 50 times per second.
6.Magnet
7.Movable coil - coil turns inside of the permanent magnet in the center of the executive device. When an electrical impulse reaches the coil, causes her turn, and this in return causes shift of the lever of executive device.
8.Sector - on each track there are several sectors
9.Step motor - This motor is turning plates with speed of several thousand spins per minute
10.Track - Before first use, magnetized coating on each panel shares on the concentric tracks using special signal from the computer, a process called formatting.
11.A set of plates - information is stored on both of their sides.
Read-write Head - Once the head is correctly positioned, the magnet on top of her sends electrical pulses to ensure that the data will be written into proper sector.Binar data (0 and 1), encoded by electric current direction change, turnin into harmonized patterns in the "domains". The data from the disc is read the reversing the procedure, ie the passage of "domain" below the electromagnet, which induces a current in the wire.
1.Electromagnet - When data is written to disk, electrical impulses arriving there, produce magnetic fields that align "domains" on the track below.
2.Wire - this wire transfer written or read data registered between "read-write" head and the supervisory mechanism of the disk.
3."Domains" with data - Each domain is arranged in one of two possible directions. Changing direction in relation to the previous position of "domains" means 1, and when there is no change means zero.
4.Freely ordered "domains" - Where on the disc were never even written data, "domains" are freely ordered.

How touch-sensitive devices work?
Technologies of touch-sensitive devices to control a computer are developed in two directions. First, the monitor can act as a measuring sensor and respond to the tip of your finger or other object and turn the touch into an electrical signal. monitor systems that respond to touch, are widely used in the management of automated counters and other movements that require gentle control. Another solution is to use plastic pads as measurement sensors. First, they were widely used with graphic panels, and today have become an integral part of many laptop computers. Movement of finger
rectangular pad stimulates identical run the cursor on the monitor. In most of these measuring senses moving fingers changes the distribution of electric voltage in switches of pad causing large differences in electrical signals. With the use of pads that respond to touch,moving cursor can reach the speed of up to 100 cm per second.
The system of touch-sensitive monitors - Electricity, released through the coating on the base layer of glass, produces a static electric field. Touching the monitors interfere with the field, and these changes the processor graphicaly displays.
2.Image Processor - The processor constantly scans an image of the electrostatic field. when changes occur in the image, processor makes calculation of coordinates.
3.The appearance of the electric field - a layer of conducting electricity with register changes in electrical voltage caused by touch.
4.The front layer of glass - the glass is electrically low voltage field that is changeable at the touch of a finger.
