cop 1000 Introduction to Computers and
Programming chapter 1
Program(software) - correct answer ✔A set of instructions that a computer
follows to perfrom a task.
Hardware - correct answer ✔refers to all of the physical devices, or
components, that a computer is made of.
Major components of a computer - correct answer ✔The central processing
unit (CPU), main memory, secondary storage devices, input devices, output
devices
central processing unit - correct answer ✔part of a computer that actually
runs programs
Main memory - correct answer ✔Where the computer stores a program while
the program is running, as well as data as the data that the program is
working with. also known as random access memory, or RAM. It is called this
because the CPU is able to quickly access data stored at any random location
in RAM.
Secondary storage device - correct answer ✔Type of memory that can hold
data for long periods of time, even when there is no power to the computer
Input device - correct answer ✔Input is any data the computer collects from
people and from other devices The component that collects the data and
sends it to the computer is called an input device
, output device - correct answer ✔output is any data the computer produces
for people or for other devices. The is sent to an output device, which formats
and presents it.
bytes - correct answer ✔A computer's memory is divided into tiny storage
locations
bit (binary digit) - correct answer ✔Tiny electrical components that can hold
either positive or a negative charge
ASCII - correct answer ✔set of 128 numeric codes that represent the English
letters, various punctuation
marks, and other characters.
Computers are able to store negative numbers and real numbers in memory,
but to do
so they use encoding schemes along with the binary numbering system.
Negative numbers
are encoded using a technique known as two's complement, and real
numbers are
encoded in floating-point notation. - correct answer ✔
Digital data - correct answer ✔stored in binary
digital device - correct answer ✔any device that works with binary data
instruction set - correct answer ✔The entire set of
instructions that a CPU can execute
