The essential difference between a computer and a calculator is what can be done

The essential difference between a computer and a calculator is that it can temporarily and permanently store large amounts of complex information and run complex information processing programs, while a calculator can only temporarily store a small amount of digital information and run simple mathematical calculation programs.

The essential difference is:

Calculator: temporarily stores a small amount of numerical information and runs simple mathematical calculation programs;

Computer: temporarily and permanently stores large amounts of complex information and runs complex information processing programs;

Calculator:

also has certain computing power and programming capabilities, but is very simple . For example, those used by our clerks, accountants, and market vendors mainly use calculation capabilities such as addition, subtraction, multiplication, and division (addition is the most, so the keys are the largest). For more complicated work, the storage function may be used, that is, programs are used; The MR key on the calculator is called memory read, which means reading the storage. The MC key is called memory clear. The Chinese MS key is called memory save. The Chinese is called memory save. M: Add M- in the storage: Subtract in the storage and it is complicated. Some scientific calculators can use more complex functions such as trigonometric functions, measurements, and currency conversions, but are limited to general mathematical operations and basic temporary storage;

Computer:

An electronic computer (later commonly known as a computer) can store information temporarily (such as memory) and permanently (such as hard disks and chips). The content that can be saved is no longer numbers, it can be text, pictures, audio and video, programs, any information that can be digitized. The information is massive, complex, and no longer numbers. Another essential difference is that computers no longer simply calculate mathematical problems. From a few lines of code to solving chickens and rabbits in the same cage, to various application software, operating systems, and high-performance cluster computing, as long as they can be thought of at present, they are complex. It must be solved by electronic computers. For example, AlphaGo killed the human brain, which is enough for calculators to look up to.
