Hexadecimal is a positional numeral system that uses sixteen symbols to represent numbers. Learn how to write, distinguish and convert hexadecimal values in mathematics and computing, and see examples of hexadecimal notation in different contexts.
Learn how computers represent numeric values in binary, octal and hexadecimal systems. Find out the definitions and examples of bits, bytes, nibbles and other terms related to computer number formats.
An octet is a unit of digital information that consists of eight bits. Learn how octets are used in computing, telecommunications, Internet protocol addresses and unit multiples, and the difference between octet and byte.
Web colors are colors used in displaying web pages on the World Wide Web; they can be described by way of three methods: a color may be specified as an RGB triplet, in hexadecimal format (a hex triplet) or according to its common English name in some cases. Learn how to convert RGB to hexadecimal, use shorthand hexadecimal, and access HTML color names.
Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...
This is because the radix of the hexadecimal system (16) is a power of the radix of the binary system (2). More specifically, 16 = 2 4, so it takes four digits of binary to represent one digit of hexadecimal, as shown in the adjacent table. To convert a hexadecimal number into its binary equivalent, simply substitute the corresponding binary ...
Binary-coded decimal (BCD) is a binary encoding of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Learn about the different types of BCD, their advantages and disadvantages, and their applications in computing and electronic systems.
These are often represented as either decimal or hexadecimal numbers. High-end digital image equipment are often able to deal with larger integer ranges for each primary color, such as 0..1023 (10 bits), 0..65535 (16 bits) or even larger, by extending the 24-bits (three 8-bit values) to 32-bit , 48-bit , or 64-bit units (more or less ...
