what is the difference between hardware and software interrupt?
609183
Hardware interrupt is an interrupt generated from an external device or hardware. Software interrupt is the interrupt that is generated by any internal system of the computer.

Stop Process = SIGSTOP (pause signal, let's you continue later with SIGCONT, does not kill process) End Process = SIGTERM (termination signal, the right way, the application can intercept this signal and intiate shutdown tasks such as temp file cleanup)

Interrupt handling is not a disadvantage of priority scheduling in OS. ... It is considered to be one of the most commonly used 'scheduling algorithms' in batch processing systems.

The term was coined to differentiate these instructions from hardware—i.e., the physical components of a computer system. A set of instructions that directs a computer's hardware to perform a task is called a program, or software program. The two main types of software are system software and application software.

Inside the CPU At the hardware level, a CPU is an integrated circuit, also known as a chip. An integrated circuit "integrates" millions or billions of tiny electrical parts, arranging them into circuits and fitting them all into a compact box.

The big difference is that you know where the subroutine runs (because you call it). ... Simply, a subroutine is code you write and call as required, an interrupt is system bound and cannot be called by the user but occurs when something happens (sources are hardware, software and CPU) that requires immediate attention.

A register is most definitely hardware! It's a block of memory (made up of flip flops), and is typically eight bits in size. A register located inside a CPU--in comparison to other types of memory such as RAM--is very quickly and easily accessible to the hardware that actually operates on information.

Hardware and software Hardware is the physical components of the computer, such as the central processing unit (CPU) , hard disk , monitor , keyboard and mouse. Software is the programs that run on a computer. Hardware is the physical components of a computer.

Software vs Firmware: What Is the Difference? ... Software files are usually large and take up a substantial amount of hardware memory when compared to firmware. Firmware is a term for a piece of software that is stored on a hardware device in order to make it run properly.

In essence, the main difference between the two is the fact that hardware engineers work on developing the physical bits of a computer, and its peripherals. Software engineers, on the other, hand, use the products of hardware engineer's labor to design and implement new software.

The main difference between API and system call is that API is a set of protocols, routines, and, functions that allow the exchange of data among various applications and devices while a system call is a method that allows a program to request services from the kernel.

When a user program invokes a system call, a system call instruction is executed, which causes the processor to begin executing the system call handler in the kernel protection domain. ... Switches to a kernel stack associated with the calling thread. Calls the function that implements the requested system call.

The so-called top half is the routine that actually responds to the interrupt—the one you register with request_irq. ... The big difference between the top-half handler and the bottom half is that all interrupts are enabled during execution of the bottom half—that's why it runs at a safer time.

The kernel performs its tasks, such as running processes, managing hardware devices such as the hard disk, and handling interrupts, in this protected kernel space. In contrast, application programs like browsers, word processors, or audio or video players use a separate area of memory, user space.

A kernel resides between hardware and OS. It communicates with hardware using system calls. Every programming language require a compiler to compile the code written in high level language and then it generate low level code, which is generally assembly language code.

is that software is (computing) encoded computer instructions, usually modifiable (unless stored in some form of unalterable memory such as rom) compare hardware while tool is (computing) a piece of software used to develop software or hardware, or to perform low-level operations.
