Computers do not understand natural languages, such as English or Spanish, but they can understand and execute instructions that are written in a programming language. DDSRY.com
Programming languages are artificial languages that are specifically designed to be used by computers to perform tasks.
There are many different programming languages, each of which has its own syntax and rules. Some popular programming languages include C++, Java, Python, and C#. To write code in a programming language, a programmer will use a text editor or integrated development environment (IDE) to enter their instructions, which are then saved as a file with a specific extension depending on the programming language being used.
Once the code has been written, it can be compiled, or translated, into a form that the computer can understand and execute. The resulting program can then be run to perform the tasks specified in the code.
Overall, computers can only understand and execute instructions that are written in a programming language, and they rely on programmers to create programs and applications that can be used to perform useful tasks.
