Q291.
What is an interpreter?

a.

A program that reads a program's bytecode executable and executes it directly on the host processor

b.

A program that translates high-level bytecode instructions into dozens of instructions on the physical CPU

c.

A program that reads a program's bytecode executable and executes it in a virtual environment implemented in software

d.

A program that takes snippets of program bytecode at runtime and compiles them into the native processor's machine language before running them

Discuss
Answer: (c).A program that reads a program's bytecode executable and executes it in a virtual environment implemented in software Explanation:An interpreter is a program that reads a program's bytecode executable and deciphers each instruction and "executes" it in a virtual environment implemented in software. It manages the data accessed by the bytecode program, which means that the bytecode program would not have direct access to the host CPU's registers.
Q292.
What is an interpreter?

a.

A program that reads a program's bytecode executable and executes it in a virtual environment implemented in software.

b.

A program that compiles bytecode into the native processor's machine language.

c.

A program that obfuscates sensitive information from bytecode executables.

d.

A program that reconstructs high-level language representations from bytecode executables.

Discuss
Answer: (a).A program that reads a program's bytecode executable and executes it in a virtual environment implemented in software. Explanation:An interpreter is a program that reads a program's bytecode executable and executes it in a virtual environment implemented in software.
Q293.
What is the major drawback of interpreters?

a.

They are difficult to use for beginners.

b.

They do not provide a high-level language representation of the program.

c.

They do not allow direct access to the host CPU's registers.

d.

They result in slower program execution compared to running directly on the host's CPU.

Discuss
Answer: (d).They result in slower program execution compared to running directly on the host's CPU. Explanation:The major drawback of interpreters is that they result in slower program execution compared to running directly on the host's CPU.
Q294.
What is metadata?

a.

Detailed data type information found in bytecode executables.

b.

A low-level language used in bytecode executables.

c.

A program that eliminates sensitive information from bytecode executables.

d.

A program that reconstructs high-level language representations from bytecode executables.

Discuss
Answer: (a).Detailed data type information found in bytecode executables. Explanation:Metadata is detailed data type information found in bytecode executables.
