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.
Not 2 numbers - 2 digits. The digits 0 and 1.
Binary.
The binary representations of the decimal numbers from 20 to 30 are as follows: 20: 10100 21: 10101 22: 10110 23: 10111 24: 11000 25: 11001 26: 11010 27: 11011 28: 11100 29: 11101 30: 11110 These binary numbers represent their respective decimal values.
No. In general, their internal processing is in binary numbers and there are programs that enable them to work with hexadecimal numbers.
Computers store and process data in binary form: current on or off, location magnetised or not, laser reader hits a pit or not.
BINARY
No. All computers only understand binary, which is 0 as "off" and 1 as "on."
Binary numbers, with or without a computer are a series of 1's and 0's.
Computers primarilary work with the Binary numbering system (0 and 1) which is known as Base 2.
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.
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.
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)
Its all in binary really. As each binary number refers to the pixel it will hold to form the shape after.
Not 2 numbers - 2 digits. The digits 0 and 1.
Computers use binary numbers. This is ones and zeros.
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),
