First-generation programming languages (1GL) are low-level languages that are directly understandable by a computer’s hardware. This means that they’re written in machine code, which is the binary language (comprised of 1s and 0s) that the computer’s processor can interpret and act upon.

As an example, a simple instruction in machine code might look like this: 10110000 01100001. This binary instruction tells the computer to perform a specific operation, such as moving a value to a register, or adding two numbers together.

While first-generation programming languages offer the advantage of fast execution and efficient use of memory, they’re extremely difficult for humans to read or write due to their binary nature. In addition, programs written in a 1GL are specific to a particular type of hardware and are not portable to different systems.

Because of these limitations, higher-level programming languages have been developed that are easier for humans to work with. Second-generation programming languages (2GL) are assembly languages that use short, mnemonic codes to represent the basic operations of the machine. Third-generation programming languages (3GL), like C, Java, and Python, are even more abstract and user-friendly, while still being able to be compiled or interpreted into machine code.
