CNIT 315 EXAM 1 PREP QUESTIONS & ANSWERS
1. bit- Answers - smallest most basic data item in a computer. 0 or 1, open or closed switch
2. byte- Answers - a group of 8 bits
3. character codes (ASCII, Unicode)- Answers - collection of 0 and 1 that represent single letters, single
digits and other single characters
4. word- Answers - combinations of 1 or more bytes
5. RAM- Answers - Main memory unit of a computer. Volatile so data is lost when power is lost. Measured in Mega or Giga
bytes
6. Control unit- Answers - 1/2 of the CPU. Monitors overall operation of the computer. Know when the next
instruction resides, issues signals to read wrtie data, executes all instructions
7. Arithmetic Logic Unit (ALU)- Answers - 1/2 of the CPU. Performs all computations like addition,
subtraction, comparisons
8. Microprocessor- Answers - The central processing unit that is generally made from a single integrated circuit.
9. Computer program- Answers - data and instructions used to operate a computer and produce a
results. Set of programs is called software
10. programming- Answers - written instructions in a language that computers and other programs can
understand
11. programming language- Answers - set of instructions that can be used to construct a program
12. executable program- Answers - a program that can operate on a computer. They are made of binary
13. machine language- Answers - computers internal language made up of 1 and 0. Execitanle programs
are made of binary
14. opcode- Answers - tells the computer the operation to be performed
15. assembly language- Answers - substitution of word like symbols for the opcodes and decimal numbers
and labels for memory addresses
1/8
, 16. low level languages- Answers - machine and assembly language. both use instructions that are directly
tied to one type of computer
17. source program/code- Answers - a program written in a high-level language
18. Interpreted Language- Answers - Code that is translated one line/instruction at a time.
19. interpreter- Answers - a program used to translate each statement in a high level source program and execute it
after translation
20. compiled language- Answers - Translates the entire program, creating an executable program which can
be run at a later time
21. Compiler- Answers - A computer program created to read an entire program and convert it into a lower-level
language and ultimately to assembly language used by the processor.
