COMPUTER SCIENCE EXAM STUDY GUIDE
1. PCs ANS A relatively small computer designed to be used by one person at a
time. Most home computers are PCs.
2. Workstation ANS A larger and more powerful PC. "Industrial Strength."
3. Mainframes ANS An even larger computer that typically requires some support
staff and generally is shared by more than one user.
4. Network ANS A number of computers connected so that they may share
resources such as printers and may share information. A network might contain a
number of workstations and one or more mainframes as well as shared devices such
as printers.
5. Input Devices ANS Any device that allows a user to communicate info to the
computer such as a keyboard and a mouse.
6. Output Devices ANS Is anything that allows the computer to communicate
information to the user such as a display screen (monitor) or printer.
7. Main Memory ANS Consists of a long list of numbered locations called memory
locations.

8. Bit ANS A digit that can assume only the values of 0 and 1 also called binary digit.
The memory locations in most computers contain 8 bits.
9. Byte ANS An 8 bit portion of memory.
10. Address ANS The number that identifies a byte. The address of the byte is
then used to find the data item when needed.
11. Memory Location ANS Entire chunk of memory that holds a large data item
such as a large number.
12. Secondary Memory (storage) ANS Is the memory that is used for keeping a
permanent record of
information after (and after) the computer is used (auxiliary memory, auxiliary storage,
external memory, and external storage).
13. Files ANS Information in secondary storage is kept in units called files.
14. CDs, DVDs, disks, and diskettes (floppy disks) ANS Secondary Storage devices
15. RAM ANS Random Access Memory, Main Memory, Can be immediately
accessed by the computer in any memory location

16. Processor ANS Known as the central processing unit or CPU. It is the brain of
the computer.
17. Chip ANS The processor. Follows an instruction in a program and performs the
calculations specified by the program. 18. Operating System ANS How
communication between a computer is conducted. Allocates the computer's resources
to the different tasks that the computer must accomplish. Delivers your requests to
other servant programs.
19. Program ANS A set of instructions for a computer to follow.
20. Data ANS What we conceptualize as the input to the program. The input to
the program, both data and program are input to the computer.
21 Running a Program ANS Whenever we give a computer both a program to follow
and data we are said to be running the program on the data.
22. Executing a Program ANS When the computer performs the program
23. High Level Language ANS Resemble human languages. Designed to be easy for
humans to write programs in.
