COMPUTER SCIENCE AN OVERVIEW
CHAPTERS 1 TO 8 PRACTICE EXAM 2026
PREMIUM QUESTIONS AND ACCURATE
ANSWERS ONE HUNDRED PERCENT CORRECT
◉ 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
-A program or instructions that give directions to the computer.
-Any programs that are stored in memory so that they can be
executed later
◉ Freeware.
Answer: software that is free to use. Unlike commercial software, it
does not require any payment or licensing fee. It is similar to
shareware, but will not eventually ask you for payment to continue
using the software. You can legally download and use freeware for as
long as you want without having to pay for it.
◉ Shareware.
Answer: software that you can use on a trial basis before paying for
it. Unlike freeware, shareware often has limited functionality or may
only be used for a limited time before requiring payment and
registration. Once you pay for a shareware program, the program is
fully functional and the time limit is removed.
, ◉ Memory.
Answer: The ordered sequence of storage cells that can be accessed
by address. Instructions and variables of an executing program are
temporarily held here.
-Computer memory is set up to represent and store information in
electronic form
-The information stored in memory can represent any type of data,
such as numbers, text, images, or sound, or the instructions of a
program
◉ CPU.
Answer: A major hardware component that consists of the
arithmetic/logic unit and the control unit. Also sometimes called a
processor.
-Central Processing Unit; the brain of the computer.
-Executes an algorithm by fetching its binary instructions from
memory, decoding them, and executing them
-Main chip in a computer
-Controls the activities of other chips as well as the devices
connected to the computer such as the monitor and the printer
-Large number of terminals
