Assembly Language Questions Long
The purpose of input/output (I/O) operations in Assembly Language is to enable communication between the computer system and external devices such as keyboards, monitors, printers, disk drives, and network interfaces. These operations allow the assembly program to interact with the user, receive input data, process it, and produce output results.
Input operations involve reading data from external devices into the computer's memory for further processing. For example, an assembly program may use an input operation to read user input from the keyboard or retrieve data from a file stored on a disk. This data can then be used by the program to perform calculations, make decisions, or manipulate it in some way.
On the other hand, output operations involve sending data from the computer's memory to external devices for display or storage. For instance, an assembly program may use an output operation to display results on a monitor, print data on a printer, or save data to a file on a disk.
I/O operations in Assembly Language are typically performed using specific instructions provided by the processor or through predefined I/O routines provided by the operating system. These instructions or routines allow the program to control the flow of data between the computer and external devices.
Overall, the purpose of I/O operations in Assembly Language is to facilitate the exchange of data between the computer system and external devices, enabling the program to interact with the user, process input data, and produce output results.
