Data Representation in Computer: Number Systems, Characters
A computer uses a fixed number of bits to represent a piece of data which could be a number, a character, image, sound, video, etc. Data representation is the method used internally to represent data in a computer. Let us see how various types of data can be represented in computer memory. Before discussing data representation of numbers, let ...

PDF Number Systems, Base Conversions, and Computer Data Representation
Decimal and Binary Numbers. When we write decimal (base 10) numbers, we use a positional notation system. Each digit is multiplied by an appropriate power of 10 depending on its position in the number: For example: 843 = 8 x 102 + 4 x 101 + 3 x 100 = 8 x 100 + 4 x 10 + 3 x 1 = 800 + 40 + 3. For whole numbers, the rightmost digit position is the ...

PDF Data Representation
We can represent numbers using only the digits 0s and 1s with the binary number system. Instead of counting the number of 1s, 5s, 10s, and 25s in coins, or 1s, 10s, 100s, and 1000s in abstract amounts, count the number of 1s, 2s, 4s, 8s, etc. For example, 1101 in binary is 1 * 8 + 1 * 4 + 0 * 2 + 1 * 1 = 13 in decimal.

Data Representation, Number Systems and Arithmetic Processes
The importance of the binary technique has been stressed as a practical method of achieving the inherent speed and accuracy by removing tight tolerances from the actual voltage levels used by the electronics. The representation of non-numeric data, such as alphabetic characters, is also important. This chapter reviews the commonly used techniques.

Introduction to number systems and binary
The base 10 (decimal) system is the most common number system used by humans, but there are other important and useful number systems. For example, base 2, called binary system, is the basis of modern computing. We can convert between the decimal form and binary form of a number to solve different problems.
How do computers represent data?
How do computers represent data? When we look at a computer, we see text and images and shapes. To a computer, all of that is just binary data, 1s and 0s. The following 1s and 0s represents a tiny GIF: This next string of 1s and 0s represents a command to add a number: You might be scratching your head at this point.
Data Representation
Mantissa, Significand and fraction are synonymously used terms. In the computer, the representation is binary and the binary point is not fixed. For example, a number, say, 23.345 can be written as 2.3345 x 101 or 0.23345 x 102 or 2334.5 x 10-2. The representation 2.3345 x 101 is said to be in normalised form.

d n-1 = Most significant bit (MSB) d-m = Least significant bit (LSB). 1. Decimal to Binary Number System. To convert from decimal to binary, start dividing decimal number by 2, and whatever the reminder getting, writing down from bottom to top, and that will be the binary number representation of the decimal number. And the number contains fractional part, then multiply 2 in the fractional part.
A Tutorial on Data Representation
Number Systems. Human beings use decimal (base 10) and duodecimal (base 12) number systems for counting and measurements (probably because we have 10 fingers and two big toes). Computers use binary (base 2) number system, as they are made from binary digital components (known as transistors) operating in two states - on and off. In computing, we also use hexadecimal (base 16) or octal (base 8 ...
Types of Number Systems: Decimal, Binary, Octal & Hexadecimal
Binary Number System; Octal Number System; Hexadecimal Number System; Decimal Number System. A number system with a base value of 10 is termed a Decimal number system. It uses 10 digits i.e. 0-9 for the creation of numbers. Here, each digit in the number is at a specific place with a place value of a product of different powers of 10.
