Computer Glossary Set – 3

1. Copy right

It means the material and information are the personal property of the owner or producer.

2. Cache

A cache stores recently-used information in a place where it can be accessed extremely fast.

Common type of cache is a disk cache. This stores information you have recently read from your hard disk in the computer’s RAM, or memory.

Another type of cache is a processor cache which stores small amounts of information right next to the processor.

3. CAD – Computer-Aided Design

CAD software is used for nearly all three-dimensional designing.

4. Card Reader

Card reader  is the generic term for an input device that reads flash memory  cards.

It can be a standalone device that connects to a computer via USB or it may be integrated into a computer, printer, or multifunction device.

5. CCD – Charged Coupled Device

CCDs are sensors used in digital cameras and video cameras to record still and moving images.

The quality of an image captured by a CCD depends on the resolution  of the sensor. In digital cameras, the resolution is measured in Megapixels.

6. CDMA – Code Division Multiple Access

CDMA is a wireless transmission technology.

CDMA is a digital technology, analog audio signals must be digitized  before being transmitted on the network.

CDMA is used by 2G and 3G wireless communications and typically operates in the frequency range of 800 MHz to 1.9 GHz.

7. Checksum

A checksum is a calculated sum used to check the integrity of a file.

It can be generated from one of many algorithms, such as cyclic redundancy check (CRC) or a cryptographic hash function.

8. CGI – Common Gateway Interface

It is a standard set of rules that define how scripts and Programs can be run on a Web Server.

9. Clock Cycle

A clock cycle, or clock tick, is one increment of the CPU clock, during which the smallest unit of Processor activity can be performed.

The Clock Speed of a processor is measured in clock cycles per second, or “hertz.”

10. CISC – Complex Instruction Set Computing

CISC architecture contains a large set of computer instructions that range from very simple to very complex and specialized.
