Installable device drivers allow the OS to support new devices without updating the OS.
The device drivers allow the operating system to communicate with peripheral devices.

Invention patented by Hubert Kuo and I-Ming Lin on March 17th, 2003. Abstract: An embedded control unit is installed in a notebook computer, so as to take the place of the programmable processor in many conventional notebook computers for controlling peripheral devices. The embedded control unit includes a plurality of peripheral controllers, so as to control the peripheral devices usually used by typical notebook computers. The peripheral controllers can be directly connected to the peripheral devices, according to the specifications for different types and/or brands of notebook computers. In addition, the peripheral controllers can achieve control of the peripheral devices according to the non-adjustable internal register settings. In this way, the control of the peripheral devices can be achieved without using firmware, thereby simplifying the notebook computer development process and reducing the development cost.
so as to infom the processor of what it ought to do
what manages the computers hardware? THE TEXTBOOK ANSWER IS THE OPERATING SYSTEM
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.
they are called pheripherals.

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).
A modem is a peripheral device based on the fact that peripheral devices are devices located on the outside of a computer
