STUDY GUIDE 2026 FULL QUESTIONS AND
SOLUTIONS
◉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. Answer: a symbol or letter, such as "x" or "y," that
represents a value
◉Hardware. Answer: The computing machine and its support
devices
-Consists of the physical devices required to execute algorithms
-Consists of the physical components connected together to function
as a computer
◉Processors. Answer: Can locate data in a computer's primary
memory very quickly
◉Software. Answer: Programs that make the machine (the
hardware) do something, such as word processing, database
management, or games
