1. When compared to the compiled program, scripts run
  1. Faster

  2. Slower

  3. The execution speed is similar

  4. All of above


Correct Option: B
Explanation:

To answer this question, the user needs to know the difference between a compiled program and a script.

A compiled program is a set of machine-readable instructions that are generated by a compiler from high-level programming language source code. The compiled program is then executed directly by the computer's CPU.

On the other hand, a script is a set of instructions written in a programming language that is interpreted by an interpreter at runtime. The interpreter reads and executes the code line by line instead of generating machine code.

Now, let's go through each option and explain why it is right or wrong:

A. Faster: This option is generally incorrect. Compiled programs are usually faster than scripts because they are already translated into machine code. The computer can execute machine code directly, which is faster than interpreting source code line by line.

B. Slower: This option is generally correct. Scripts are usually slower than compiled programs because they need to be interpreted at runtime. The interpreter has to read and execute the code line by line, which is slower than executing machine code directly.

C. The execution speed is similar: This option is generally incorrect. In most cases, compiled programs are faster than scripts. However, there may be some cases where the execution speed is similar, such as when the compiled program is poorly optimized or the script is highly optimized.

D. All of the above: This option is incorrect. Option A and C contradict each other, so they cannot both be correct. Option B is generally correct, but there may be some rare cases where a script is faster than a poorly optimized compiled program.

Therefore, the correct answer is:

The Answer is: B. Slower
