A 32 binary number is a number stored by a computer in 32 bits. it can represent:
1) An unsigned number in the range 0 to 4,294,967,295
2) A signed number in the range -2,147,483,648 to 2,147,483,647
3) A single precision IEEE floating point number with 1 sign bit, 8 exponent bits and 23 mantissa bits give an accuracy of about 7.2 decimal digits and a range of ± 10^-38 to 10^38

Why people are using Hexadecimal rather than binary numbers while doing programs?
hexadecimal can express 16 bit binary in 4 place form, not 16.
How do you represent binary tree using array?
The root of the tree is stored in array element [0]; for any node of the tree that is stored in array element [i], its left child is stored in array element [2*i], its right child at [2*i+2]
What are example files of data encoding?
Not to be flippant, but every file is an example of data encoding. Before data can be stored in computer memory or in a disk file, it first has to be digitally encoded in binary. The binary encodings can then be further encoded using encryption or compression.
What are two advantages of using binary numbers rather than decimal numbers in a computer system?
Your question is actually flawed...binary system is not used in digital systems... Rather, systems using binary numbers only are called digital systems... It is common knowledge that, digital electronics employs just 2 states (or rather numbers, as mathematicians put it...) the two numbers being '0' and '1'. Obviously, it is easier to design electronic systems dealing with just 2 states...It's majorly this ease, that led to such exponential development in the field of digital electronics. It ios also cheaper to make or produce such systems...
What is the absolute machine code?
The very lowest possible level at which you can program a computer is in its own native machine code, consisting of strings of 1's and 0's and stored as binary numbers. The main problems with using machine code directly are that it is very easy to make a mistake, and very hard to find it once you realize the mistake has been made.
Signed binary multiplier?
Binary multiplier is taking numbers and using multiplication and division. This is used in math.
A way of counting using the numbers 0 and 1?
Ithink it's called binary Ithink it's called binary
What is a method for representing numbers using only 0 and 1?
binary system
What is a way of counting using the numbers 0 and 1?
Use the binary system.
How do you convert letters to numbers?
There are many different systems of using numbers to represent letters. Binary is commonly used.
A system of numbers in which each number is shown using only the digits 0 and 1?
binary.
What is the Largest real number that can be stored in binary using 16 bits?
1111 1111 1111 1111 = 2^16 = 65536
When using the rule for subtracting binary numbers 1-1 equals what?

How is scientific notation related to the floating point representation used by computers?
Floating point numbers are stored in scientific notation using base 2 not base 10.There are a limited number of bits so they are stored to a certain number of significant binary figures.There are various number of bytes (bits) used to store the numbers - the bits being split between the mantissa (the number) and the exponent (the power of 10 (being in the base of the storage - in binary, 10 equals 2 in decimal) by which the mantissa is multiplied to get the binary/decimal point back to where it should be), examples:Single precision (IEEE) uses 4 bytes: 8 bits for the exponent (encoding ±), 1 bit for the sign of the number and 23 bits for the number itself;Double precision (IEEE) uses 8 bytes: 11 bits for the exponent, 1 bit for the sign, 52 bits for the number;The Commodore PET used 5 bytes: 8 bits for the exponent, 1 bit for the sign and 31 bits for the number;The Sinclair QL used 6 bytes: 12 bits for the exponent (stored in 2 bytes, 16 bits, 4 bits of which were unused), 1 bit for the sign and 31 bits for the number.The numbers are stored normalised:In decimal numbers the digit before the decimal point is non-zero, ie one of {1, 2, ..., 9}.In binary numbers, the only non-zero digit is 1, so *every* floating point number in binary (except 0) has a 1 before the binary point; thus the initial 1 (before the binary point) is not stored (it is implicit).The exponent is stored by adding an offset of 2^(bits of exponent - 1), eg with 8 bit exponents it is stored by adding 2^7 = 1000 0000Zero is stored by having an exponent of zero (and mantissa of zero).Example 10 (decimal):10 (decimal) = 1010 in binary → 1.010 × 10^11 (all digits binary) which is stored in single precision as:sign = 0exponent = 1000 0000 + 0000 0011 = 1000 00011mantissa = 010 0000 0000 0000 0000 0000 (the 1 before the binary point is explicit).Example -0.75 (decimal):-0.75 decimal = -0.11 in binary (0.75 = ½ + ¼) → 1.1 × 10^-1 (all digits binary) → single precision:sign = 1exponent = 1000 0000 + (-0000 0001) = 0111 1111mantissa = 100 0000 0000 0000 0000 0000Note 0.1 in decimal is a recurring binary fraction 0.1 (decimal) = 0.0001100110011... in binary which is one reason floating point numbers have rounding issues when dealing with decimal fractions.

Why prefer hex numbers using in microcontroller?
Internally, computers work in binary, but presenting those in hexadecimal makes for more compact numbers (one hex digit for every four binary digits), and is therefore easier to read.
