Question 1

An example of an assembly language instruction is:
A)Divide
B)DIV X
C)Divx
D)All of the above
E)None of the above

Accepted Answer

"DIV X" is an example of an assembly language instruction, where "DIV" is the operation code and "X" is the operand. Choice A is not a valid assembly language instruction as it lacks an operand. Choice C is not a valid instruction due to incorrect syntax.

Question 2

The accumulator is used to:
A)Store input data
B)Temporarily store intermediate results
C)Permanently store instructions
D)None of the above
E)a,b,and c

Accepted Answer

D

Question 3

Assembly language and machine language are the same.

Accepted Answer

Assembly language is a low-level programming language that uses human-readable instructions which are translated into machine language (binary code) by an assembler. Machine language, on the other hand, is the lowest level of programming language consisting of binary code understood directly by the computer's hardware.

Question 4

Assembly language is a direct translation from machine language.

Accepted Answer

Assembly language is a low-level programming language that is a symbolic representation of machine code, which directly corresponds to the binary instructions used by a computer's CPU.

Question 5

Assembly language uses three letters to indicate an instruction.

Accepted Answer

Assembly language uses short codes made up of three letters to indicate an instruction. For example, the instruction "mov" is used to move data from one location to another.

Question 6

A programmer using assembly language has more control of the program than when using a high level language.

Accepted Answer

Assembly language is a low-level programming language that provides direct access to computer hardware resources, giving the programmer more control over the program's behavior and efficiency. In contrast, high-level programming languages abstract the underlying hardware and provide more convenient and portable abstractions, but at the cost of reduced control and performance.

Question 7

Assembly language uses the accumulator for calculations.

Accepted Answer

In assembly language, the accumulator is a register that is commonly used for arithmetic and logic operations. It holds the data temporarily during calculations.

Question 8

Registers are used for temporary storage.

Accepted Answer

Registers are used for temporary storage of data during the execution of instructions in a CPU. They are usually faster to access than other forms of memory, making them ideal for frequently used or time-critical data.

Question 9

Compilers are faster than assembly language.

Accepted Answer

Compilers translate high-level programming languages into machine code, which can introduce overhead and optimization challenges. Assembly language, being closer to machine code, allows for more direct and potentially faster execution when well-written.

Question 10

Assembly language is used to speed up games.

Accepted Answer

Assembly language is a low-level programming language that is closer to machine language and can optimize the performance of games by directly controlling hardware components. Many game developers use assembly language for critical parts of the game engine to achieve faster processing speeds.

Question 11

Assembly language is one step up from machine language.

Accepted Answer

Assembly language uses mnemonics that represent machine language instructions, making it easier for humans to read and program compared to raw machine language.

Question 12

Registers are used to:
A)Store input data
B)Temporarily store intermediate results
C)Permanently store instructions
D)None of the above
E)a,b,and c

Accepted Answer

Registers are small, high-speed storage locations used to temporarily hold instructions and data that the CPU is currently processing. They are used to store intermediate results during calculations and computations. Registers do not permanently store instructions or data, and they only store input data temporarily until it is processed.

Question 13

All assembly languages are the same.

Accepted Answer

Assembly languages vary depending on the processor architecture they are designed for. Different processors have different instruction sets, so assembly languages must be tailored to each specific architecture. Therefore, assembly languages are not the same.
