QUESTIONS AND CORRECT ANSWERS
⩥ Algorithm.
Answer: A finite sequence of instructions that, when applied to a
problem, will solve it.
-The sequence of steps that describes each of these computational
processes
-Describes a process that ends with a solution to a problem
⩥ Infinite number of instructions (?).
Answer: Describing something without any bound, as many instructions
as needed
⩥ Computing Agent.
Answer: The entity that executes instructions in an algorithm
-an object capable of understanding and executing our instructions
⩥ Data.
,Answer: The symbols that are used to represent information in a form
suitable for storage, processing, and communication
-Information
-Computing agent manipulates information (input to output)
⩥ Variable.
Answer: A memory location, referenced with a key and is located by a
key in a collection
⩥ Input.
Answer: Data obtained by a program during its execution
-Given information
-The purpose of most of the input devices is to convert information that
human beings deal with, such as text, images, and sounds, into
information for computational processing
⩥ Output.
Answer: Information that is produced by a program
-New information
-The purpose of most output devices is to convert the results of this
processing back to human-usable form
⩥ Processor.
, Answer: a small chip that resides in computers and other electronic
devices. Its basic job is to receive input and provide the appropriate
output.
⩥ Program.
Answer: A set of instructions that tells the machine (the hardware) what
to do
⩥ Bits.
Answer: binary digits
⩥ Records.
Answer: a database entry that may contain one or more values. Groups
of records are stored in a table, which defines what types of data each
record may contain. Databases may contain multiple tables which may
each contain multiple records.
⩥ Input.
Answer: Keyboard, a mouse, and a microphone
⩥ Output.
Answer: Monitor and speakers
⩥ Variables.
