Principle of the modern Electronic computer was proposed by Alan Turing in his seminal 1936 paper, On Computable Numbers.

FactSnippet No. 1,402,703

Electronic computer proved that such a machine is capable of computing anything that is computable by executing instructions stored on tape, allowing the machine to be programmable.

However, any Electronic computer that is capable of performing just the simplest operations can be programmed to break down the more complex operations into simple steps that it can perform.

FactSnippet No. 1,402,708

Therefore, any Electronic computer can be programmed to perform any arithmetic operation—although it will take more time to do so if its ALU does not directly support the operation.

In general, the contents of RAM are erased when the power to the Electronic computer is turned off, but ROM retains its data indefinitely.

FactSnippet No. 1,402,710

One means by which this is done is with a special signal called an interrupt, which can periodically cause the Electronic computer to stop executing instructions where it was and do something else instead.

Software refers to parts of the Electronic computer which do not have a material form, such as programs, data, protocols, etc.

FactSnippet No. 1,402,712

In most cases, Electronic computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc.

Once told to run this program, the Electronic computer will perform the repetitive addition task without further human intervention.

FactSnippet No. 1,402,714

Since the Electronic computer's memory is able to store numbers, it can store the instruction codes.
