When a peripheral device needs immediate attention from the operating system, it generates an interrupt signal. This signal notifies the CPU that the device requires processing, prompting the OS to pause its current tasks and address the request. The OS then determines the appropriate action to take, such as reading data from the device or handling an error. This mechanism allows for efficient and timely communication between the CPU and peripheral devices.
The device drivers allow the operating system to communicate with peripheral devices.
operating system
Operating systems usually communicate with peripherals using "drivers", which are usually written by the designers\manufacturers of the peripheral. Drivers are essentially programs or processes that the operating system loads which contain the necessary routines and information to make use of the peripheral.
A device driver.
Correct Answer: Device Driver
A laser generates an electromagnetic wave operating at light frequencies.
so as to infom the processor of what it ought to do
what manages the computers hardware? THE TEXTBOOK ANSWER IS THE OPERATING SYSTEM
Device management controls peripheral devices by sending them commands in their own proprietary language. The software routine that knows how to deal with each device is called a "driver," and the OS requires drivers for the peripherals attached to the computer. When a new peripheral is added, that device's driver is installed into the operating system
Spooling stands for Simultaneous Peripheral Operations Online. It is a technique used in operating systems to manage input/output (I/O) operations between fast devices (like the CPU) and slow devices (like printers or card readers).
On the first computers, without an operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral-2like printers and card-readers. Not every computer had an operating system.
Peripheral devices are connected and logged to the CPU through interfaces like USB, SATA, or PCIe, which facilitate communication between the device and the processor. When a peripheral is connected, the operating system detects it using device drivers that manage data transfer and functionality. The CPU then communicates with the device through memory-mapped I/O or direct I/O, allowing the system to recognize and interact with the peripheral efficiently.
