It expresses — usually by means of punctuation marks (though it can include numbers and letters) — a person's feelings or mood, though as emoticons have become more popular, some devices have provided stylized pictures that do not use punctuation.

Almost all integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed. These are known as the power-supply pins. However, the labeling of the pins varies by IC family and manufacturer.

In mathematical logic and computer science, the Kleene star (or Kleene operator or Kleene closure) is a unary operation, either on sets of strings or on sets of symbols or characters. In mathematics it is more commonly known as the free monoid construction. The application of the Kleene star to a set V is written as V^*. It is widely used for regular expressions, which is the context in which it was introduced by Stephen Kleene to characterise certain automata, where it means "zero or more".

In mathematics, a square root of a number a is a number y such that , in other words, a number y whose square (the result of multiplying the number by itself, or ) is a. For example, 4 and -4 are square roots of 16 because .

Virgin TV have taken a different approach to rival Sky's Sky+ HD service, by implementing a rental scheme for the V+ Box. When Virgin TV was launched, there was an installation charge (waived under certain circumstances) and a monthly charge for all customers with a discount for XL customers. On 1 June 2007 pricing was revised, with all customers paying a one-off set-up fee and TV M and L customers paid a monthly charge, while TV XL customers had no extra charges. Various deals to lower the set-up fee have been made available to all customers in order to compete with rival Sky.

It was nominated for a National Book Award.

Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction. It is also used in the verification of analog circuits and mixed-signal circuits.
