Study Notes
Smart Card Reader
- A device used to access the microprocessor of a smart card
- Two types of smart cards: Memory cards (non-volatile memory storage components and specific security logic) and Microprocessor cards (volatile memory and microprocessor components)
Optical Mark Reader (OMR)
- Interpret marks into a data record and send it to the computer for storage, analysis, and reporting
- Widely used in reading answers of objective type tests, voting applications, and evaluation studies
- Uses a beam of light to detect marks on a paper and capture presence and absence of data
Optical Character Recognition (OCR)
- Technique for scanning a printed page, translating it, and using OCR software to recognize the image as ASCII text
- Widely used in acquiring textual data from images in applications like telephone bills, electricity bills, and insurance premium
Biometric Sensor
- Device that recognizes physical traits of an individual
- Used for marking attendance of employees/students in organizations/institutions
Joystick
- Device that moves in all directions and controls the movement of the cursor
- Used in flight simulators, Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) system, etc
- Similar to a mouse, but the movement of the cursor on screen stops as soon as the user stops
Barcode Reader
- Machine-readable representation of information in the form of stripes of dark and light ink
- Used in applications like supermarkets to read the price of a product with a barcode
Computer Hardware
- Fifth generation: Super Large Scale Integrated (SLSI) chips, optical discs, and parallel processing
- Features: artificial intelligence, knowledge processing, and microprocessor implementation enable mega chips
