COMPUTER CONCEPTS MODULE 1
MODULE 14 FINAL PAPER QUESTIONS
AND SOLUTIONS
◉ Byte
Answer: tiny storage locations that a computer's memory is
divided into. Enough to store a letter of the alphabet or a small
number.
◉ Bit
Answer: binary digit; 1/8 of a byte. Tiny switches that can be
turned on or off.
◉ Binary numbering system
Answer: The numbering system that represents all numbers using
just two symbols (0 and 1).
◉ ASCII
Answer: American Standard Code for Information Interchange
◉ two's complement
Answer: A method of representing negative numbers in the binary
system.
,◉ Floating Point notation
Answer: A real number represented by a sign, some significant
digits (the mantissa) and a power of 2 (the exponent).
◉ What amount of memory is enough to store a letter of the
alphabet or a small number.
Answer: a byte
◉ What do you call a tiny switch that can be set to either on or
off?
Answer: bit
◉ In what numbering system are all numeric values written as
sequences of 0s and 1s?
Answer: Binary
◉ What is the purpose of ASCII?
Answer: It is an encoding scheme that uses a set of 128 numeric
codes to represent the English letters, various punctuation marks,
and other characters. These numeric codes are used to store
characters in a computer's memory. (ASCII stands for the
American Standard Code for Information Interchange.)
◉ What encoding scheme is extensive to represent all the
characters of all languages of the world?
Answer: Unicode
, ◉ What do the terms digital data and digital device mean?
Answer: Digital Data-data stored in binary
Digital Device-any device that works with binary
◉ Machine language
Answer: Binary code made up of 0s and 1s; usually this is data
converted from a high-level language by a compiler. Often used as
a synonym for low-level programming language.
◉ CPU's instruction set
Answer: The entire set of instructions that a CPU can execute
◉ Fetch-Decode-Execute Cycle
Answer: The process that the CPU uses to retrieve and execute
instructions
◉ Fetch
Answer: reading the next instruction from memory into the cpu
◉ Decode
Answer: CPU decodes the instruction fetched from memory to
determine which action to perform.
