24.
A group of eight bits joined together.
25.
A physical signal, such as text, numbers, graphics, or sound, interpreted by converting it into binary numbers.
26.
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.
27.
The representation of text by assigning a unique binary code to each character.
28.
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.
29.
The measurement in bytes of the volume that a storage device can contain. Storage space is measured in kilobytes (1024 bytes), megabytes (1024 kilobytes), gigabytes (1024 megabytes), and terabytes (1024 gigabytes).
30.
The measurement in bits per second that information is transferred through a network from one computer to another. Throughput is measured in Kbps (kilobits per second), Mbps (megabits per second), and Gbps (gigabits per second).
31.
Pronounced ask-ee and short for American Standard Code for Information Interchange, the most common format for text files in computers on the internet where each character is represented by a unique 7-bit binary code. Extended ASCII uses an 8-bit binary c
32.
An international 16-bit encoding standard that accommodates character sets from multiple languages, with each letter, digit, or symbol being assigned a unique numeric value.
33.
Information that a user physically enters into a computer by pressing a key on a keyboard, clicking a mouse, tapping a touch screen, pushing a button on a game controller, speaking into a microphone, etc.
34.
The operations performed by a computer to retrieve, transform, or classify information.
35.
Information that a computer returns to a user such as images on a screen, sounds from speakers, and printed pages.
36.
The saving of information on memory chips, discs, or other storage media by a computer for later use.
37.
An early computing machine that used punched cards and metal pins. It was used to compile the 1890 US census.
38.
A smaller, faster, cheaper, and more durable electronic device that replaced mechanical relays, which were slow and tended to wear down over time.
