Assembly Language Questions
The basic components of Assembly Language are:
1. Instructions: Assembly Language consists of a set of instructions that are used to perform specific tasks. These instructions are written using mnemonic codes that represent specific operations, such as addition, subtraction, or data movement.
2. Registers: Assembly Language uses registers as temporary storage locations for data manipulation. These registers are small, high-speed memory locations that can hold a limited amount of data. They are used to store operands, intermediate results, and addresses.
3. Memory: Assembly Language interacts with the computer's memory to store and retrieve data. Memory is divided into individual cells, each of which has a unique address. Assembly Language instructions can access and manipulate data stored in memory.
4. Labels and Symbols: Assembly Language allows the use of labels and symbols to represent memory addresses or constants. Labels are used to mark specific locations in the program, while symbols are used to represent constants or variables.
5. Directives: Assembly Language includes directives that provide instructions to the assembler, which is a program that converts Assembly Language code into machine code. Directives are used to define data, reserve memory space, or control the assembly process.
6. Macros: Assembly Language supports the use of macros, which are predefined sequences of instructions that can be used repeatedly in a program. Macros help in code reusability and simplifying complex operations.
7. Interrupts: Assembly Language allows the use of interrupts, which are signals that can be generated by hardware or software to interrupt the normal flow of program execution. Interrupts are used for handling events, such as user input or hardware events.
These components together form the foundation of Assembly Language programming, providing a low-level interface to interact with the computer's hardware and perform specific tasks efficiently.
