Among the generation of programming language (1st - 3rd), which would use LOAD r1, ADD r1 or DIV r2?
The combination of instructions "LOAD r1, ADD r1" or "DIV r2" would be typically associated with the second generation of programming languages, specifically assembly languages.
To understand this better, let's break it down:
1. First-generation programming languages were machine languages, which used binary code to write instructions. Instructions written in machine language were specific to the architecture of the computer's hardware.
2. Second-generation programming languages, known as assembly languages, were developed to make programming easier. Assembly languages use mnemonic codes to represent machine instructions. These mnemonics are then translated to machine code using an assembler.
In assembly language, the "LOAD" instruction is used to load a value from memory into a register, and "ADD" is used to perform addition on the value in a register. So, in the instruction "LOAD r1, ADD r1," the value stored at the memory address pointed by r1 is loaded into r1, and then r1 is added to itself.
3. Third-generation programming languages are high-level languages, such as C, Java, or Python. These languages are further removed from the computer's hardware and are designed to provide more abstraction and readability for programmers. In high-level languages, instead of writing individual instructions like "LOAD r1, ADD r1," you would use higher-level constructs and functions to achieve the desired operations.
To summarize, the instructions "LOAD r1, ADD r1" or "DIV r2" are typically associated with assembly languages, which fall under the second generation of programming languages.
