Which programming generation uses abbreviations or mnemonics such as ADD that are automatically converted to the appropriate sequence of 1s and 0s?

The programming generation that uses abbreviations or mnemonics such as ADD that are automatically converted to the appropriate sequence of 1s and 0s is the second-generation programming language, also known as assembly language.

Here are the steps to understand this:

1. The first-generation programming language is machine language, which is the only language a computer can execute directly. It consists entirely of numbers and is almost impossible for humans to read and write.

2. The second-generation programming language, or assembly language, is a slight abstraction above machine language. Instead of writing in binary (1s and 0s), programmers use mnemonics or abbreviations (like ADD for addition, SUB for subtraction, etc.) to represent machine operations and memory locations.

3. An assembler is then used to convert the assembly language into machine language that can be understood by the computer.

4. Higher-level languages (3rd, 4th, and 5th generations) use more complex syntax and semantics, allowing programmers to write code that is more human-readable and abstracted from the machine language.

So, the answer to your question is the second-generation programming language.
