When we say a system is a multiprogramming system?
Multiprogramming is collecting several jobs in a job pool and the OS selects the job from the pool so that the CPU has one job to execute , in case of any IO request for the job in execution the CPU switches to another job here switching is less compared to multitasking.So a computer system which allows such type of switching in between jobs is called a multiprogramming system. Please make note that multitasking is done by user but multiprogramming is done by operating system only.
How resident monitor work in batch operating system?

What is pooling in the field of operating system?

What does verifying DMI pool data mean?
DMI or DesktopManagement Interface (pdf) is a layer of abstraction between system components and the software that manages them. The System Management BIOS (SMBIOS) is an extension of the Basic Input Output System (BIOS) that formulates and delivers this information to the operating system. The pool data is the information. In short, when the BIOS is "Verifying DMI pool data" it is verifying the table of data it sends to the operating system (Windows, etc.).
What is spooling in operating system with diagram?
spooling is a term used in computers and it means place an operation that is being run by the operating system in a temporary are until another action is taken. For example sending a print job from your computer to the printer. The operating system places the sent job in a temporary folder until action is taken by the printer. Thanks
What is a multi program system?
A group of jobs that are ready to be executed is called job pool. Since there is more than one job that can be executed, it is possible for the operating system to make a decision about which job to execute next. That decision keeps CPU utilization as high as possible. In general, it is not possible for a single user to keep CPU or I/O devices busy at all times. Multiprogramming allows the system .to increase CPU utilization by ensuring that the CPU always has a job to execute. The CPU has a pool of jobs. When the currently executing job has to wait (if it is performing some I/O), it is removed from the CPU- Another job is selected and the CPU now executes it. This process ensures that CPU is always executing a job if there is a job to execute. In a non-multiprogrammed system, if a job had to wait for an I/O operation, CPU would also have to wait until I/O was finished. Hammad Ali

What is distributed system in operating system?
A distributed system in operating system, is simple the distribution of jobs among the different unit of a computer system. Eg:- When printing a picture the job are distributed among different unit of a computer such as a processor , RAM, and a printer..ETC
What is the job control unit inside unit CPU?
Job control is a system function and is handles by an operating system. The CPU does not candle any job control functions. Job control is on a much higher level that the CPU is not designed to handle.
