Von Neumann programming languages are computer languages that can communicate with the computer's memory. This means that the language can tell the computer what it needs to do, and where to find the data it needs to do it.
Think of it like making a grocery list: you write down everything you need from the store, and where you can find each item in the store. This way, once you get to the store, you know exactly what to get and where to find it.
Similarly, von Neumann programming languages allow computer programs to make a list of what they need to do, and where to find the information to do it. Once the program is executed, it checks off each item on the list, and moves on to the next one until the task is complete.
This is different from other programming languages that may rely more on external sources for information or require the programmer to manually input everything into the computer's memory. Von Neumann programming languages are a powerful tool for creating efficient and effective computer programs.
