Question 14

Plain, unformatted text is sometimes called ASCII text.​

Accepted Answer

ASCII (American Standard Code for Information Interchange) text is a standard for encoding characters and symbols in plain text format. It uses 7-bit binary code to represent characters, and is a widely accepted standard in computing.

Question 15

Transmission speeds are expressed in _______, whereas storage space is expressed in _______.​
A)​bits, bytes
B)​bytes, bits
C)​binary, numeric
D)​none of the above

Accepted Answer

Transmission speeds are measured in bits per second (bps), whereas storage space is measured in bytes (usually KB, MB, GB, or TB).

Question 16

Character data is composed of letters, symbols, and numerals that are used in calculations.​
