Operating Systems
1. In your own words, what is an operating system?
An operating system connects the PC or computer to the software that is run on it and
thus, creates a common place for all the software that you use.
6. What is a software interrupt? What does it do?
A software interrupt is a special type of signal generated by various hardware events
or some software events that need an immediate response from the processor. It causes
the operating system to temporarily stop what it is doing to divert its attention to the
service required by the signal.
7. What are system resources?
System resources are the parts within a computer that are available to be used by the
operating system and other applications.
8. What is“Plug and Play”?
Plug and Play is a term that describes the characteristic of an universal serial bus, or
device specification, which facilitates the discovery of a hardware component in a system
without the need for physical device configuration; this includes USB systems.
9. What is “hot swapping”?
Hot swapping is the function of replacing computer system components without
shutting down the system and without significant interruption to the system; thus, once

Document Summary
A software interrupt is a special type of signal generated by various hardware events or some software events that need an immediate response from the processor. Resource arbitration is when the operating system decides what resources to allocate to each device and the system then tells the enumerators what resources it allocated to their respective devices. A device driver is a small piece of add-on code that tells the operating system the facts about a piece of hardware the system needs to communicate with it. It is also a block of code tailored to control a specific hardware peripheral, becoming an extension of the. A file handle is an abstract indicator for accessing a file and is also called a file descriptor. It is generally an index for an entry in a kernel-resident data structure containing the details of all open files.
