Because the computer has to know how big the number is, and whether it's a

positive or negative number. Otherwise, there would be a lot of wrong answers,

and people would blame them on the computer.

What Numbers that computers use to store and process data?

BINARY


Are binary numbers used mostly in the science of computers?

No. All computers only understand binary, which is 0 as "off" and 1 as "on."


Computers process binary numbers which are composed of?

Binary numbers, with or without a computer are a series of 1's and 0's.


What numbers do computers depend on?

Computers primarilary work with the Binary numbering system (0 and 1) which is known as Base 2.


Why do computers process binary numbers?

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.


How do computers store informations?

ALL Computers read write store information as binary (1 and 0's) in representations of bits(smallest representation of information) and bytes (8 bits make a byte)


Why no websites tell us why binary is invented?

Binary system is invented to allow its use for computers where "on" is for one and "off" is for zero. So, numbers could be easily identified by the computers.


Explain the methods which are available to store negative numbers and how are they used. Which method is mainly used today and why?

signed magnitude, one bit indicates the sign of the number and the other bits indicate the positive magnitude of the number (this system has two representations for zero: +0 and -0)one's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude (this system has two representations for zero: +0 and -0)two's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude plus one (this system is asymmetric about zero, with one more negative value than positive)offset binary, numbers are represented as the positive sum of their actual value and an offset (this system is asymmetric about zero, typically with one more negative value than positive)Most modern systems use two's complement for fixed point numbers (because the arithmetic circuitry is simpler than the others) and a combination of signed magnitude and offset binary for floating point numbers (because this format allows the same instructions for comparing fixed point numbers to also be used to compare floating point numbers, reducing the number of different instructions and the circuitry to implement them),


In what form numbers are stored in computers binary or ASCII form?

Its all in binary really. As each binary number refers to the pixel it will hold to form the shape after.


What 2 numbers are used in the binary code for computers?

Not 2 numbers - 2 digits. The digits 0 and 1.


What Calculations were made with the first computer?

Computers use binary numbers. This is ones and zeros.


What is the name for the counting system used by computers that contains only the numbers 0 and 1?
