what is the difference between binary and hexadecimal?

Binary is a system of numbers based on two symbols: 0 and 1. Digital computers process and store all data in binary. Hexadecimal is a system of numbers based on sixteen symbols: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. It is easy to convert binary into hexadecimal and vice versa.

hex. My book says the hexadecimal notation FFFF equals 65535 in decimal value. As I understand it that equals to 2^16.

Computers rely on binary numbers and binary math because it greatly simplifies their tasks. Since there are only two possibilities (0 and 1) for each digit rather than 10, it is easier to store or manipulate the numbers.

The bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. ... The result has the same type as the left operand (after the arithmetic conversions).

Binary numerals are used for doing math, because they are easy to add, subtract, and multiply. Gray code is used in situations where a change to an adjacent number would create a “race condition ” between different bits.

Binary operator requires two operands and Unary operator requires one operand. ... Here, in -5, the minus sign is unary operator and it requires one operand which is 5 here. The minus sign between 5 and 6 is binary operator which requires two operands(-5 and 6 here). The minus sign in -11 is also unary operator.

A binary digit is called a bit. There are two possible states in a bit, usually expressed as 0 and 1. A series of eight bits strung together makes a byte, much as 12 makes a dozen. With 8 bits, or 8 binary digits, there exist 2^8=256 possible combinations.

The value of HEX 2F in decimal is 47. The value of HEX 2F in binary is 00101111. F. 15 X 160 =

The main difference between Binary file and text file is the format of contents within the the file. ... Binary file contains the data in the form of 0 and 1(series of binary values) and text files contains the data in the form of stream of characters.In general binary files are identified as executable files.

Advantages and Disadvantages The main advantage of using Octal numbers is that it uses less digits than decimal and Hexadecimal number system. So, it has fewer computations and less computational errors. It uses only 3 bits to represent any digit in binary and easy to convert from octal to binary and vice-versa.

A binary image has only two values for each pixel, 0 and 1 corresponding to black and white (or vice versa). A gray scale image has a certain number (probably 8) bits of information per pixel, hence, 256 possible grey values.

Binary code can have different lengths for encoding depending on the number of characters, instructions, or the encoding method, but ASCII uses only 7 digits long binary string and 8 digits long for extended ASCII.

In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow).

Difference between Single and Double Precision: In single precision, 32 bits are used to represent floating-point number. In double precision, 64 bits are used to represent floating-point number.

decimal refers to a number system in base 10. That means you write it using the digits 0-9. The Integers are the set of numbers that include the Natural numbers, their negatives, and 0. You can write an Integer in decimal, in octal, in hexidecimal, in binary...but no matter how you write it, the value is the same.

While both binary and text files contain data stored as a series of bits (binary values of 1s and 0s), the bits in text files represent characters, while the bits in binary files represent custom data. While text files contain only textual data, binary files may contain both textual and custom binary data.
