A system call is not triggered by hardware directly; rather, it is initiated by a program running in user mode when it needs to request a service from the operating system, such as file access or network communication. The process typically involves a software interrupt or trap that switches the CPU from user mode to kernel mode, allowing the operating system to safely execute the requested operation. While hardware interrupts can signal the operating system to handle events (like I/O completion), system calls are primarily software-driven.
What else can I help you with?
What type of operating system are designed primarily to maximize resource utilization?
A system call is triggered by hardware!
What do you call a library of hardware drivers that operate between the OS and hardware that is installed on the system?
It sounds to me like you are referring to the kernel of the operating system.
What is meant by a system call in operating system?
A "System call" you be a function accessible from a programming language to the base hardware of the computer (eg to get the time).
What is the nervous system triggered to respond to?
The nervous system is triggered to respond to stimuli.
How call the devices that set up a computer system?
The devices that make up a computer system are collectively called computer hardware. A complete computer system must however also have software.

Interrupts originate with what?
Interrupts originate from hardware or software events that require immediate attention from the CPU. Hardware interrupts are generated by devices such as keyboards, mice, or network cards to signal that they need processing, while software interrupts can be triggered by system calls or exceptions in programs. These interrupts allow the CPU to respond quickly to changing conditions or requests, ensuring efficient multitasking and system responsiveness.
How a operating system is related to computer hardware?
The operating system (OS) controls the hardware. A successful computer system will have hardware and an operating system. Application software is not required. All operating systems have a low level, or machine language to run the operation system and control all hardware.
If you were to be a plus certified what would your certification cover?
Hardware And Operating System
What are software interrupt?
Software interrupts are signals generated by a program to request the attention of the operating system or to invoke specific system functions. They are typically used for system calls, allowing applications to communicate with the operating system to perform tasks such as accessing hardware or managing memory. Unlike hardware interrupts, which are triggered by external devices, software interrupts are initiated by the software itself, enabling more controlled interactions within the system. This mechanism enhances multitasking and resource management in modern operating systems.
