Chapter Six - Low-Level Programming & Pseudocode

Question 1

machine language?

Answer 1

• language used DIRECTLY by the computer (made up up BINARY CODED instructions);

Question 2

virtual computer (machine)?

Answer 2

• HYPOTHETICAL machine designed to ILLUSTRATE IMPORTANT FEATURES of real machine (–> PEP/8 = virtual computer; 39 machine language instructions; we make a hypothetical machine because because real life machine code typ. differs from machine to machine)

Question 3

loader?

Answer 3

• SOFTWARE that takes a MACHINE LANGUAGE PROGRAM and places it into MEMORY (working with Pep/8) –> when you write the code for the program in Pep8 and press the “PLAY” aka loader

Question 4

assembly language?

Answer 4

• LOW LEVEL programming language in which MNEMONIC represents EACH of the machine-language INSTRUCTIONS for a particular computer.

Question 5

assembler?

Answer 5

• program that translates ASSEMBLY MACHINE LANGUAGE into MACHINE CODE

Question 6

assembler directive?

Answer 6

• instructions that go to the assembler

Question 7

comment?

Answer 7

• // -> explanatory text for the human reader

Question 8

algorithm?

Answer 8

• PLAN/OUTLINE for a SOLUTION; logical SEQUENCE of steps that solve a problem

Question 9

pseudocode?

Answer 9

• LANGUAGE designed to express ALGORITHMS

Question 10

boolean expression?

Answer 10

• EXPRESSION that WHEN EVALUATED is either true or false

Question 11

test plan?

Answer 11

• document that specifies HOW a PROGRAM is to be TESTED(how many times and which data program is going to run)

Question 12

code coverage (clear-box) testing?

Answer 12

• approach that designs test cases to ensure that EACH STATEMENT in the program is EXECUTED

Question 13

data coverage (black-box) testing?

Answer 13

• designing test cases that ensures that the limits of the allowable data are covered.

Question 14

test plan implementation?

Answer 14

• running the data coverage and code coverage testing…
