Ans: Assembler is software program which converts assembly language program into machine understandable binary language. Ans: Mnemonics are the symbolic representation of opcodes. They are generally group of 3 or 4 alphabets, to easily remember the Opcode Operation code. Ans: The language which uses the mnemonics to write a program. The manufacturers of microprocessor give the mnemonics. The Hardware refers to the components or devices used to form computing machine in which the software can be run and tested.
Join our Community. In this chapter we will explore the concept of interrupts and interrupt programming. Upon receiving an interrupt signal, the microprocessor holds whatever it is doing and serves the corresponding device. The program associated with the interrupt is called the interrupt service routine ISR or interrupt handler. In POLLING method, the microprocessor continuously monitors the status of a given device; when the status condition is met, it performs the service.

Most of the general functions and services offered by DOS are implemented through this interrupt. Well behaved programs, therefore, should use these facilities in preference to any other methods available for the widest range of compatibility. Within this range some calls have subfunctions which further extend the range of operations. In all calls, on entry AH defines the function. Other parameters may also be required in other registers. Where a memory block is used by the call this is specified in the normal segment:offset form.

Normalmente, este. Neste caso, um byte.
Все внезапно осложнилось, пошло совсем не так, как он рассчитывал. Мелкая любезность, которую он оказал Стратмору, забрав личные вещи Танкадо, вылилась в поиски таинственного кольца, как в известной игре, где нужно находить спрятанные предметы. Дэвид только что позвонил Стратмору и рассказал о немецком туристе.
