Q71.
What is the purpose of an assembler program?

a.

To read object code and generate the textual mapping of each instruction in it.

b.

To perform the reverse operation of disassembler.

c.

To translate the textual assembly language code into binary code.

d.

To generate high-level programming language code.

Discuss
Answer: (c).To translate the textual assembly language code into binary code. Explanation:When developers write code in assembly language, they use an assembler program to translate the textual assembly language code into binary code, which can be decoded by a CPU.
Q72.
What is the purpose of a disassembler?

a.

To read binary code and generate the textual mapping of each instruction in it.

b.

To perform the reverse operation of an assembler.

c.

To generate high-level programming language code.

d.

To translate textual assembly language code into binary code.

Discuss
Answer: (a).To read binary code and generate the textual mapping of each instruction in it. Explanation:A disassembler reads object code and generates the textual mapping of each instruction in it. This is a key tool for reversers.
Q73.
How does a compiler translate a high-level language program into machine code?

a.

By writing a machine-generated assembly language program

b.

By decoding the high-level language program directly

c.

By generating a corresponding bytecode file

d.

By generating a corresponding machine code file

Discuss
Answer: (d).By generating a corresponding machine code file Explanation:A compiler is a program that takes a source file and generates a corresponding machine code file.
Q74.
What is the biggest hurdle in deciphering compiler-generated code?

a.

The use of platform-independent bytecode

b.

The optimizations applied by most modern compilers

c.

The high-level language used in the source file

d.

The lack of a disassembler program

Discuss
Answer: (b).The optimizations applied by most modern compilers Explanation:The biggest hurdle in deciphering compiler-generated code is the optimizations applied by most modern compilers.
Q75.
What is the purpose of a disassembler program?

a.

To translate machine code into bytecode

b.

To generate a corresponding machine code file

c.

To translate object code into assembly language

d.

To generate a corresponding assembly language program

Discuss
Answer: (c).To translate object code into assembly language Explanation:A disassembler does the exact opposite. It reads object code and generates the textual mapping of each instruction in it.
Q76.
What is a bytecode?

a.

A standard platform-specific object code.

b.

A machine-readable object code.

c.

A platform-independent format that is decoded directly by the CPU.

d.

A platform-independent format that is decoded by a virtual machine.

Discuss
Answer: (d).A platform-independent format that is decoded by a virtual machine. Explanation:Bytecodes are encoded in a special platform-independent format called bytecode, which is decoded by a virtual machine.
Q77.
What is a virtual machine?

a.

A program that generates machine code.

b.

A program that decodes a source code file.

c.

A program that decodes a bytecode file.

d.

A program that generates a source code file.

Discuss
Answer: (c).A program that decodes a bytecode file. Explanation:A virtual machine is a program that decodes a bytecode file and performs the operations described in it.
Q78.
What is the benefit of using a bytecode-based language?

a.

Platform independence

b.

Machine-generated assembly language program

c.

Ease of understanding

d.

Minimization of code size

Discuss
Answer: (a).Platform independence Explanation:One significant advantage of using bytecode-based languages is platform independence.
Q79.
What is an operating system?

a.

A program that manages the hardware and software applications of a computer.

b.

A program that manages only the hardware of a computer.

c.

A program that manages only the software applications of a computer.

d.

None of the above.

Discuss
Answer: (a).A program that manages the hardware and software applications of a computer. Explanation:An operating system is a program that manages the computer, including the hardware and software applications.
Q80.
How can an operating system be seen in a computer?

a.

As a kind of coordinator between the different elements.

b.

As a hardware component.

c.

As a software application.

d.

None of the above.

Discuss
Answer: (a).As a kind of coordinator between the different elements. Explanation:An operating system can be seen as a kind of coordinator between the different elements in a computer.
