• Processor Spped

• Encoded Text

A group of eight bits joined together.

• Processor Speed

• Throughput

A physical signal, such as text, numbers, graphics, or sound, interpreted by converting it into binary numbers.

• Digital Data

• Bit

• Throughput

• ASCII

The representation of integers using a group of bytes. Normally, one bit in one of the byes represents the sign, 1 for negative and 0 for positive. The remaining 31 bits are used to encode the number itself using binary digits.

• Encoded Integers

• Encoded Text

• Throughput

The representation of text by assigning a unique binary code to each character.

• Hexadecimal System

• Bit

• Encoded Text

• Byte

The speed at which a computer processes information, as measured by the number of cycles per second (Hertz) that the computer's CPU operates at. Processor speed is measured in kilohertz, megahertz, and gigahertz.
