ELI5: Explain Like I'm 5

First-generation programming language

Imagine you want to tell a computer what to do, like making a drawing of a dog. However, computers only understand special codes and instructions, kind of like their own secret language.

First-generation programming language is the earliest form of this secret language that humans used to talk to computers. It involves using binary code, which is made up of only two numbers – 0 and 1.

Think of it this way:
Imagine you want to draw a dog, you would need to break it down into very simple instructions using only two symbols, like a 'dot' and a 'line'. These symbols can represent numbers, which a computer can then understand.

Each of these numbers are made up of zeros and ones, that the computer can interpret. For example, 00001 might mean draw a line, and 00010 could mean draw a dot.

Using first-generation programming language, humans could give these simple instructions to a computer and make it do what they wanted. Although it was not an easy task, because it required knowledge of computer architecture and machine language, it paved the way for further development of programming languages, including higher-level languages that humans can easily understand.
