Question 3-3

Assembler-A program that converts the assembly language source program to the corresponding machine language program

Complier-The program that converts high-level language statements to machine code instructions

Loader-A computer program that loads another program into memory all operating systems including loaders

Operating System-A system software that represents a group of programs that enables the microcomputer to operate

BIOS-Basic Input/Output system

I/O-input/output-the I/O address space is the place where I/O interfaces, such as printer and monitor ports are

Implemented

Stack-temporary storage of information such as data or addresses

Heap-A common pool of free memory usable by a program. A part of the computer is memory used for

Dynamic memory allocation, in which blocks of memory are used in an arbitrary order

Source Code-programs written in assembly language

Object Code-The machine language output produced by the assembler

Real-time Application-the task required by the application must be completed before any other input to the program can occur that will alter its operation

Parallel Processing-several simultaneous operating processing units

Multi-processing-Using two or more processors in the same computer, or two or more computers connected together, to execute more than one program or instruction at the same time
