Grade 100%.
hardware - The physical components of a computer.
software - executable instructions that run on the hardware
program - a set of instructions designed to perform some task
application program - a application (app) designed to perform a task for a user
system program - program that runs (often long-term or indefinitely) and manage other programs
or are used to build other programs
operating system - a system program used to run a computer and manage application programs
on the computer. Examples: Windows, MacOS, Linux, iOS, Android.
Central Processing Unit (CPU) - executes commands from a computer's hardware and software;
the principal computer chip that contains several processing components, which determines the
computer's operating speed; the "brain" of a computer
Random Access Memory (RAM) - Computer location where instructions and data are stored on a
temporary basis. This memory is volatile.
binary digit (bit) - A digit that corresponds to the on and off states of a computer's switches. A

byte - a group of 8 bits; can represent the numbers 0 to 255
word - either four bytes (32-bit processor) or eight bytes (64-bit processor) representing one
machine instruction. A machine instruction is an instruction that can be executed by a CPU to
compare or manipulate data. A set of machine instructions comprise a program.
