  1. 2. Byte.
  2. 3. The representation and measurement of the performance or behavior of a system by continuously variable physical entities such as currents, voltages, and so on. See "digital data".
  3. 5. A part of the computer that performs arithmetic operations, logic operations, and related operations.
  4. 7. The output of "and" is True if all statements are True, False if any statement is False.
  5. 8. An ordered set of well-defined instructions for the solution of a problem in a finite number of steps.
  6. 10. Data that represents a record of data held and processed at a specific time, which is held off-line for future research or for legal reasons.
  7. 11. A program that runs in the context of a browser.
  8. 13. Pathway from memory to processing unit that carries the address in memory to and from which data is transferred. See "bus", "data bus".

  1. 1. An arrangement of data in one or more dimensions; In programming languages, an aggregate that consists of data objects, with identical attributes, each of which may be uniquely referenced by indexing.
  2. 2. A second copy of a file, to be used in the event of the original file being corrupted.
  3. 4. A pattern of vertical lines distinguished from each other by width. It can be read by a bar code reader to provide data to a computer.
  4. 5. A program that runs when translated by a Java compiler.
  5. 6. Analog-digital converter. A device for converting analog signals into digital ones for subsequent computer processing; sometimes called a "digitizer". A digital to analog (D-A) converter operates in the reverse direction.
  6. 9. American Standard Code for Information Interchange; The primary encoding character set used in computers for textual data transfer between applications. The set uses eight bits for each character code, one of these bits being a check bit to verify the seven bits needed to represent one character. ASCII represents most European alphabets. Unicode supports most known alphabets and is increasingly used in data transfer. See "Unicode".
  7. 12. See "arithmetic and logic unit".
