SCIENCE COMPREHENSIVE EXAMINATION
TEST 2026 COMPLETE QUESTIONS AND
CORRECT ANSWERS
◉ American Standard Code for Information Interchange (ASCII).
Answer: a standard encoding system for text characters that uses
numeric values to represent letters, numbers, and symbols
◉ bandwidth. Answer: the maximum rate of data transfer across a
network or communication channel, usually measured in bits per second
◉ binary. Answer: a numerical system that uses only two digits, zero
and one, to represent data in computing
◉ Boolean expression. Answer: a logical statement that can only be true
or false and uses operators like AND, OR, and NOT
◉ character. Answer: a single letter, digit, or symbol used in writing text
◉ character set. Answer: a collection of characters that a computer can
recognize and process, like ASCII or Unicode
, ◉ compression ratio. Answer: the ratio of the original data size to the
compressed data size, indicating how much the data has been reduced
◉ control structure. Answer: constructs in programming that control the
flow of execution, such as loops and conditional statements
◉ data. Answer: raw facts and figures that can be processed to produce
meaningful information
◉ data compression. Answer: the process of reducing the size of data to
save space or transmission time
◉ data types. Answer: categories of data that define what kind of value
can be stored, like integers, floats, and strings, and how it can be used
◉ declaration. Answer: a statement in programming that specifies the
name and type of a variable or function without assigning a value
◉ digital data. Answer: data represented using discrete binary values
(zeroes and ones)
◉ floating point. Answer: a way to represent real numbers that can have
fractional parts using a format that includes a base and an exponent
