ANSWERS WITH COMPLETE SOLUTIONS
100% CORRECT | UPDATED 2025
hardware - ANSWER consists of the physical devices associated with
a computer system
software - ANSWER the set of instructions the hardware executes to
carry out specific tasks
computer - ANSWER an electronic device operating under the
control of instructions stored in its own memory that can accept,
manipulate, and store data
computer system's 6 hardware components - ANSWER 1. central
processing unit (CPU)
2. primary storage
3. secondary storage
4. input devices
5. output devices
6. communication devices
, central processing unit (CPU)/ microprocessor - ANSWER the actual
hardware that interprets and executes the program (software)
instructions and coordinates how all the other hardware devices work
together; has two primary parts: control unit and ALU
control unit - ANSWER interprets software instructions and literally
tells the other hardware devices what to do, based on the software
instructions
arithmetic-logic unit (ALU) - ANSWER performs all arithmetic
operations (ex:addition/subtraction) and all logic operations
(ex:sorting/comparing numbers)
Megahertz (MHz) - ANSWER the number of millions of CPU cycles
per minute
Gigahertz (GHz) - ANSWER the number of billions of CPU cycles per
minute
complex instruction set computer (CISC) chips - ANSWER type of
CPU that can recognize as many as 100 or more instructions, enough to
carry out most computations directly
