Question

Binding of instructions and data to memory addresses can be done at :

a) Compile time
b) Load time
c) Execution time
d) All of these

Answer 1

Option D: The binding of instructions and data to memory addresses can occur at compile time, load time, or execution time, so the correct answer is all of these.

Step-by-step explanation:

The binding of instructions and data to memory addresses can be done at different stages of program processing, which are:

• Compile time: When the code is being compiled, if the physical addresses are known, binding can occur.
• Load time: If it's not possible at compile time, binding can occur at load time when the program is put into memory.
• Execution time: Sometimes, binding is delayed until the exact moment of execution, especially in systems that support dynamic memory allocation.

Therefore, the correct answer is d) All of these times. Each of these stages serves different scenarios and purposes in the lifecycle of a program.

Binding of instructions and data to memory addresses can be done at multiple stages of program execution. At compile time, memory addresses are assigned to variables and instructions in the code. At load time, the compiled program is loaded into memory and memory addresses are allocated to the instructions and data. Finally, at execution time, the binding of variables and instructions to memory addresses is finalized based on the specific location in memory where the program is being executed. Therefore, the correct answer is **d) All of these**.
