Which funtcion is performing when an operating system receives an interrupt from the printer and pauses the CPU?
In traditional programming parlance, an interrupt is handled by an Interrupt Handler. The CPU is not actually paused, but the current process that was running before the interrupt occurred is paused while the CPU processes the request. Once the Interrupt Handler returns, the application will be returned to its original running state. In modern operating systems with multiple tasks, the original application that was running may stay suspended after the interrupt completes in favor of running another process that has been suspended for some time.
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 does the operating system do if a printer does not have its own internal memory of its memory is full?
When a printer is without memory for whatever reason, the computer has to make its memory available and send the information to the computer in chunks. Chunking the transfer in this way will slow down the operation.
When do you install the network operating system?
If we need to allow personal computers to participate in computer network and shared file and printer access within a local area network (LAN). At that time after physically connecting the server computer to the network, we can install the network operating system (NOS) on the server.
How are the operating system and application software related?
Simply put, the operating system is a set of software code assembled to have the hardware of a computer performing a series of basic tasks that, working in conjunction, will provide the many functions of the computing process, like reading a record from a disk, checking a field, opening a file, sending an instruction to a printer, etc.. It is normally written in a specific programming language, which relates to the low-level code required by the machine to be understood. An application software is a piece of code that runs on top of the operating system, collecting inputs from an operator/user, submitting these data to its internal rules for processing and delivering the corresponding results to an I/O (input/output) device - a monitor, a printer, a CD-recorder, etc.. It is normally written in a high-level language, familiar to programmers and offering several aids to make the programming easier. Several application softwares can be contained in a single computer and are activated every time a specific process is to be performed. Application software needs an operating system to have the machine running, because it sends its commands (open, write, read, close) to it expecting that they will be performed in that order, and that the operating system will return the information after being processed. In fact, the application software uses the operating system as an interface between itself and the hardware, to have specific jobs performed and results delivered.
When an operating system receives interrupt from the printer and pauses the CPUwhat function is it performing?
This is known as processor management.
When an operating system receives an interrupt from the printer and pauses the CPU?
Processor management is the operating system that receives and interrupt from the printer and pauses the CPU.

HOW IS SOFTWARE INTERRUPT INITIATED?
Interrupt signals initiated by programs are called software interrupts. A software interrupt is also called a trap or anexception. A signal informing a program that an event has occurred. When a program receives an interrupt signal, it takes a specified action (which can be to ignore the signal). Interrupt signals can cause a program to suspend itself temporarily to service the interrupt. Interrupt signals can come from a variety of sources. For example, every keystroke generates an interrupt signal. Interrupts can also be generated by other devices, such as a printer , to indicate that some event has occurred. PCs support 256 types of software interrupts and 15 hardware interrupts. Each type of software interrupt is associated with an interrupt handler -- a routine that takes control when the interrupt occurs. For example, when you press a key on your keyboard, this triggers a specific interrupt handler. The complete list of interrupts and associated interrupt handlers is stored in a table called the interrupt vector table , which resides in the first 1 K of addressable memory.
How do you add the printer icon to the Google toolbar?
When you add a printer to your publishing 'toolkit', regardless of the software you're using, you add it as hardware, not as software. Google docs receives its information about your printer from the operating system feature in charge of the list of devices you have added to your computer's 'toolkit'.
What do printer drivers do?
Printer drivers - are small programs that enable the operating software (eg Windows) to recognise that the printer is attached to the computer. They literally allow the printer and computer to 'talk' to each other.
What is the recommended first step in performing printer maintenance?
The first step done when performing maintenance on a printer is to turn it off and unplug it.
What's the use of OS in PC?
The operating system tells your personal computer how to function. The operating system tells the computer how to interact with the keyboard, the monitor, the modem, and just about everything else the computer does. Your central processing unit does whatever the program tells it to do. Then it comes to a point where the program tells it to send something to the printer. It says to the operating system, "Take this to the printer." Then the operating system takes it to the printer.
What operating systems does Canon mobile printer support?
Both Windows and Mac operating system do support Can mobile printer. One should learn more from their online site, for questions or for whatever reason.
Which of the following should be handled with caution due to high operating temperature?

List and briefly define two approaches to dealing with multiple interrupts?
The discussion so far has only covered the occurrence of a single interrupt. Suppose, however, that multiple interrupts can occur. For e.g. a program may be receiving data from a communication line and printing results. The printer will generate an interrupt every time that it completes a print operation. The communication line controller will generate an interrupt every time a unit of data arrives. The unit could either be a single character or a block, depending on the nature of the communications discipline. In any case, it is possible for a communications interrupt to occur while a printer interrupt is being processed. Two approaches can be taken to deal with multiple interrupts. The first is to disable interrupts while an interrupt is being processed. A disabled interrupt simply means that the processor can and will ignore that interrupt request signal. If an interrupt occurs during this time, it generally remains pending and will be checked by the processor after the processor has enabled interrupts. Thus, when a user program is executing and an interrupt occurs, interrupts are disabled immediately. After the interrupt handler routine is completed, interrupts are enabled before resuming the user program and the processor checks to see if additional interrupts have occurred. This approach is nice and simple, as interrupts are handled in strict sequential order (Figure3.10 (a)). The drawback to the preceding approach is that it does not take into account relative priority or time-critical needs. For e.g. when input arrives from the communications line, it may need to be absorbed rapidly to make room for more input, If the first batch of input has not been processed before the second batch arrives, data may be lost. A second approach is to define priorities for interrupts and to allow an interrupt of higher priority to cause a lower-priority interrupt handler to be itself, interrupted. As an example of this second approach, consider a system with three I/O devices: a printer, a disk, and a communications line, with increasing priorities of 2, 4, and 5, respectively. A user program begins at t=0. At t=10, a printer interrupt occurs; user information is placed on the system stack and execution continues at the printer interrupt service routine (ISR). While this routine is still executing, at t=15, a communications interrupt occurs. Because the communications line has higher priority than the printer, the interrupt is honored. The printer ISR is interrupted, its state is pushed onto the stack, and execution continues at the communications ISR. While this routine is executing, a disk interrupt occurs (t=20). Because this interrupt is of lower priority, it is simply held and the communications ISR runs to completion. When the communications ISR is complete (t=25), the previous processor state is restored, which is the execution of the printer ISR. However, before even a single instruction in that routine can be executed, the processor honors the higher priority disk interrupt and control transfers to the disk ISR. Only when that routine is complete (t=35) is the printer ISR resumed. When that routine completes (t=40), control finally returns to the user program.
