However, any Modern 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.

Therefore, any Modern 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 Modern computer is turned off, but ROM retains its data indefinitely.

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

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

In most cases, Modern 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 Modern computer will perform the repetitive addition task without further human intervention.
