The difference is that a hardware interrupt is a signal relayed to a system's CPU directly because of some piece of hardware, such as a keyboard or mouse. A software interrupt is a signal sent to indicate that something within a piece of software requires attention.
A hardware interrupt is initiated from a hardware event, such as a byte received from a serial port. It is asynchronous to the running program, i.e. it can occur at any time. An internal, or software, interrupt is initiated by the running program, thus it is under the control of the running program. In the 8085, for instance, the RST instructions are software interrupts. Note, however, that external interrupts can initiate a software RST instruction, so the two events can appear to be the same kind of event. The biggest difference is the handling of the interrupt enable (IE) flag. In the hardware interrupt, the IE flag is turned off when processing the interrupt, and it is turned on right before the interrupt service routine executes the final return instruction. The software interrupt, on the other hand, has nothing to do with IE. As a result, the code must be able to tell the difference.
Hardware Interrupt: Each CPU has External Interrupt lines(about 7). Other external devices line keyboard, Mouse, Other controllers can send signals to CPU asynchronously. Software Interrupt:is an interrupt generated with in a processor by executing an instruction . Software interrupt are often used to implemented system calls because they implemented a subroutine call with a CPU ring level change.
there are several difference between computer hardware and software .fundamental difference between hardware(keyboard,printer) is a physical device and software is instructions that given to the computer(window 2000,microsoft office )etc
The difference between hardware and software is that hardware is something physical. It is something you can touch. For example, a CD and its CD-ROM drive is hardware, but the music that is recorded on it is the software.

Software is the code that a computer runs - you can not touch software, it is abstract. Hardware is what runs computer code - the physical stuff you can touch.
Cost of software for hardware
The difference between software and hardware is that hardware is a physical object. Software is digital data stored on a physical [hardware] storage device. A motherboard is a circuit board, a physical object, and therefore hardware.
Computer Science = software ECE = hardware + software + telecommunication
One is a hardware device and the other is a software implementation.
Hardware is the physical device that you can touch. Software is the collection of instructions and codes and cannot be touched.
micro controller is software and fpga is hardware
