This keypad is used to enter the numerical data. When num lock button is ON then only the numeric entries can done otherwise it act as the cursor control keypad also simple arithmetic operator and enter key. The function of the enter key and enter in the character key is the same
1 Mouse :
This is a pointer device which contains a roller in its base. When the mouse is moved on any surface, the pointer on the screen is also moved. It contains a potentiometer coupled with the roller. This potentiometer senses the motion of mouse and concerts it into digital value. A mouse may contain two or three buttons.
In computing, a mouse is a pointing device that function by detecting two-dimensional motion relative to its supporting surface. Physically ,a mouse consists of an object held under one of the user's hands, with one or buttons.
2 Scanner :
The scanner is an input device like the photocopier machine which makes the electronic copy of the picture or document which can be further edited.
A scanner is used to input paper documents or photos into the computer. They are typically "scanned" as images ( like pictures) and stored in TIFF, GIF, or JPG formed. and can also be scanned into the portable Documents Format (PDF) , or converted to text using Optical Character Recognition (OCR).
A scanner is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display. Scanners come in and flatbed types and for scanning black-and-white only, or colour. Very high resolution scanners are used for scanning for computer display. Scanners usually come with software, such as Adobe's Photoshop product, that let's you resize and otherwise modify a captured image.
4. Microphone :
The MIC is the lowest concentration of antimicrobial agent which inhibits the growth of the microorganism. A current definition of the minimum lnhibitory Concentration, MIC, is "the lowest concentration which resulted in maintenance or reduction of inoculum viability ".
Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic. Antibiotics resistance developes through mutation or plasmid exchange between bacteria of the same species. If a bacterium carries several resistance genes, it is called multiresistant or, informally, a superbug,
A microphone can be attached to a computer to record (usually through a sound card input or circuitry built into the motherboard). The sound is digitized -turned into numders that represents the original analog sound waves -and stored in the computer to later processing and playback.
Digitizer :- A Digitizer or a graphics table is input device for generating graphic. It is used to generate graphs, table's fig. etc. On the vidio screen of the computer . It's generally 2 feet square flat pad, a systems also known as a sensor is moved over the surface of the table and as it is moved, a line is drawn on the screen. To produce a map one can put the map on table and trace the outline of the map with the style. The map would be produced on the vidio screen. With the help of graphics printer, printout can be taken..
