●● Software
Answer: essential to a computer because it controls everything the
computer does
●● Main memory
Answer: where the computer stores a program while the program is
running, as well as the data that the program is working with
●● RAM
Answer: short term memory
●● Secondary storage
Answer: a type of memory that can hold data for long periods of time,
even when there is no power to the computer
●● How do traditional disk drives store data?
Answer: Magnetically encoded onto a spinning circular disk
●● Solid-state drivers
,Answer: Store data in solid state memory. Has no moving parts and
operates faster than a traditional disk drive.
●● Monitors, printers, status lights are all examples of _________
devices.
Answer: output

●● When a program runs on a computer, the part of the computer that
carries out the instructions is called the ________.
Answer: CPU
●● When a program runs on a computer, it is stored in ________.
Answer: main memory
●● RAM is called that because
a. it is optimized for random number processing
b. accesses are randomized to prevent clogging the control lines
c. you can pick any two random locations and it will take the same time
to access the data
d. when power is turned off, its contents are lost and replaced by random
bits
e. none of the above
Answer: c. you can pick any two random locations and it will take the
same time to access the data
