Final answer:
The phrase 'control is passed to a job' in computing means that the CPU starts processing that job's instructions. It is similar to being held accountable for a job in the workplace, and from a historical viewpoint, it relates to how bulletin board systems operated in the 1980s.
Step-by-step explanation:
When the phrase "control is passed to a job" is used, it typically means that the central processing unit (CPU) has begun to fetch and execute instructions from that particular program, effectively giving it the CPU's attention and resources.
This is akin to being responsible for a specific process or outcomes in the workplace, where accountability plays a crucial role in meeting expectations. Similarly, in the context of computing, once control is passed to a program, it is expected to perform its tasks correctly as it is now the primary focus of the CPU.
Considering the reference to bulletin board systems (BBS) from the 1980s, these systems were considered revolutionary at the time, providing a foundation for the future of online communication.
Although primitive by modern standards, directing input to these virtual systems required similar concepts wherein a command would give control to the BBS software to perform its function.
The phrase "control is passed to a job" refers to the transfer of control or execution from one part of a computer program to another.
It means that the central processing unit (CPU) is now executing instructions from a specific job or program. In the context of the question, it means that the processor is now fetching and executing instructions from the monitor program.
