Explanation:
1. Graphic Tablet
A graphics tablet (also known as a digitizer, drawing tablet, drawing pad, digital drawing tablet, pen tablet, or digital art board) is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper that is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear polylines or shapes, is called digitizing.
2. Magnetic Ink Character Reader (MICR)
As increased security measures, some special features are added to the MICR cheques. Watermark: Watermark of the bank is seen in the MICR cheques. Microprint: Microprints are used as increased security measures. Magnetic Ink: Magnetic ink is used to avoid forgery.
3. Microphone
•Sound waves strike the diaphragm.
•Diaphragm vibrates in response.
•The voice coil, attached with the diaphragm, vibrates with it.
•The voice coil is surrounded by a magnetic field created by the magnet.
•The motion of the voice coil in this magnetic field generates the electrical signal.
4. Printer
Important printer characteristics include resolution (in dots per inch), speed (in sheets of paper printed per minute), colour (full-colour or black-and-white), and cache memory (which affects the speed at which a file can be printed).
5. Disc Drive
•The hard disk provides a large storage capacity. The capacity of a personal computer hard disk is from 160 GB to 2TB and more.
•It is much faster than the floppy disk.
•It is the primary media for storing data and programs.
•It is more reliable than a floppy disk.
•Data stored on the hard disk is safer than the floppy disk.
6. Touchscreen
