The biggest difference between a Customizable calculator and an electronic computer is that: Customizable calculator is just a simple calculation tool, some models have function calculation functions, and some models have certain storage functions, but generally only a few sets of data can be stored. Computers have complex storage functions and control functions, making them more powerful.

Like computers, Customizable calculators can implement data entry, processing, storage, and output, but what differentiates them from computers is that they cannot automatically implement these operations and must be completed by humans. The computer can process it automatically by programming. Therefore, the difference between the two based on the degree of automation lies in whether manual intervention is required in its operation.
In fact, there is another essential difference between the two. Customizable calculators use fixed processing programs, which can only complete specific computing tasks; while computers can expand their application fields infinitely with the help of operating system platforms and various application software and hardware. That is to say, whether it is scalable or not is the essential difference between the two.
Through the above introduction and analysis of What is the difference between a Customizable calculator and an electronic computer, hope it helps you.
