To answer this question, we need to understand the concept of the maximum number of steps in a job.
In computing, a "job" refers to a task or a program that is being executed by a computer system. Each job can be divided into a series of steps or instructions that the computer follows to complete the task. The maximum number of steps in a job is determined by the computer system's architecture and limitations.
Now let's go through each option to understand why it is correct or incorrect:
Option A) 16 - This option is incorrect because 16 is a relatively low number and may not be sufficient for many complex tasks.
Option B) 255 - This option is correct because 255 represents the maximum value that can be stored in an 8-bit binary number (2^8 - 1). In some computer systems, the maximum number of steps in a job is limited to 255 instructions.
Option C) 256 - This option is incorrect because 256 exceeds the maximum value that can be stored in an 8-bit binary number. Additionally, having 256 steps in a job would require a larger memory capacity and may not be supported by all computer systems.
Option D) No limit - This option is incorrect because there is typically a limit to the number of steps in a job. Computer systems have finite resources and limitations that restrict the maximum number of instructions that can be executed in a single job.
The correct answer is B) 255. This option is correct because it represents the maximum number of steps that can be executed in a job in some computer systems.
