The idle time for a machine is the time when machine is available but is not waiting for any job to be processed. (True/False)

Answer

To determine whether the statement "The idle time for a machine is the time when the machine is available but is not waiting for any job to be processed" is true or false, we can follow these steps:

### Step 1: Understand the Definition of Idle Time
Idle time refers to the period when a machine or employee is not producing anything. This means that the machine is not engaged in any productive work.

**Hint:** Remember that idle time indicates a lack of activity, not just availability.

### Step 2: Analyze the Statement
The statement claims that idle time is when the machine is available but not waiting for any job to be processed. This implies that the machine is simply idle without any expectation of work.

**Hint:** Consider the implications of "not waiting for any job." Does this align with the definition of idle time?

### Step 3: Clarify the Concept of Waiting
Idle time can also be referred to as waiting time. This means that when a machine is idle, it is often waiting for a job to be assigned or processed. Therefore, the machine is not just available; it is also in a state of readiness for future tasks.

**Hint:** Think about what it means for a machine to be idle. Is it just sitting there, or is it prepared for the next job?

### Step 4: Conclusion
Since idle time includes the concept of waiting for jobs, the statement "The idle time for a machine is the time when the machine is available but is not waiting for any job to be processed" is incorrect. The correct understanding is that idle time includes periods when the machine is waiting for jobs.

**Final Answer:** The statement is **False**.
