Question

A single thread of control allows the process to perform :

a) only one task at a time
b) multiple tasks at a time
c) All of these

Answer 1

A single thread of control allows the process to perform a. only one task at a time, meaning it cannot handle multiple tasks simultaneously.

Step-by-step explanation:

A single thread of control in a process means that the process can perform only one task at a time. This is due to the fact that a thread is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is part of the operating system. When a process is single-threaded, it cannot multitask, meaning it has to complete one task before it can move on to the next one.

So, in relation to the multiple choice options provided, the correct answer is a) only one task at a time. Options b) and c) are incorrect because a single thread of control does not support handling multiple tasks simultaneously. The other options given, such as the evaluation of individual performance or the ease of the task, are not relevant to the single thread of control's capability to perform tasks.
