First you have to understand that the CPU pretty much reagulates electricity.
The binary system is pretty much composed of two numbers 0 and 1 which basically means that a zero equals off and one equals on.
The CPU does not "know" it is not a thinking being. What happens is that the interrupt flag ( a binary true or false register) is detected by the operating system which is being executed by the CPU and the code of the operating system runs a routine in response.
The CPU needs to understand a command keyed in by a user. The CPU can interpret only binary code, i.e. the code containing 0's and 1's. A command keyed in by user has to be translated to binary code for the CPU to understand it. An operating system performs this task.
The function of registers is the same in all computers. They are the fundamental binary interface between the internal and external structure of the CPU. All binary transactions between the CPU and its peripherals pass through registers. From the inside, they are the final periphery to the pins.
A binary system is a special type of a number system. The binary system uses only two digits, other number systems use more.
Computers use a binary system, not decimal.
The answer will depend on who "they" were or are.
The equation was based on the number 2 or the binary numeration system.
No, they use the binary system
the input signal is carried to CPU by having a binary numbers.
They use the binary code (1010101011001100)
Computers use the binary system because, electrically, it is the simplest system to use. With the binary system, there are only two types of electrical states: on and off. With other systems, there would have to be different voltages that signify different numbers.
Computers are based on a binary number system.
