Exam 6: Low-Level Programming Languages and Pseudocode

In the Pep/9 machine, the contents of the A register can be compared to the contents of a place in memory.

Each machine language instruction performs a single complex task, such as sorting a list of numbers.

A(n) _______________ is an instruction for the translating program.

Assembly language instructions are executed directly by the hardware of a particular computer.

A(n) _______________ is a program that puts a machine-language program into memory so that it can be executed.

Which of the following is not an operation that can be performed by a Pep/9 machine instruction?

Which language is actually executed by the central processing unit of a computer?

Machine language is the set of binary-coded instructions that are executed directly by a computer.

Assembly language is an abstraction, hiding some of the details that occur at the machine language level.

In _______________ testing, tests are designed based on the logic of the code.

Machine language programs are loaded into the Pep/9 simulator by specifying the instructions in hexadecimal.

The _______________ is a register used to hold the address of the next instruction to be executed.

In which of the following are tests designed based only on possible input data (rather than code)?

Given that the word length in the Pep/9 virtual computer is 2 bytes, how long is the information that flows into and out of the arithmetic/logic unit (ALU) of the PEP/9's CPU?

___________________ is an approach to computer program testing that designs tests cases to ensure that each statement in the program is executed properly.

The data-coverage testing approach tests the limits of the program's data.

Character input and output in Pep/9 uses a principle called memory-mapped I/O.

In Pep/9 assembly language, decisions can be made using instructions that check the status of the accumulator.

____________________ is an approach to computer program testing that involves designing tests to ensure that the limits of the permissible data are covered.

Which register contains the address of the next instruction to be executed?
