Use in garbage collection As a garbage collection algorithm, reference counting tracks, for each object, a count of the number of reference computer science reference s to it held by other objects. If an object s reference count reaches zero, the object has become inaccessible, and can be destroyed. When an object is destroyed, any objects referenced by that object also have their reference counts decreased. Because of this, removing a single reference can potentially lead to a large number of objects being freed. A common modification allows reference counting to be made incremental instead of destroying an object as soon as its reference count becomes zero, it is added to a list .... Simple reference counts require frequent updates.

Refimprove date November 2010 A voltage reference is an electronic device that produces a fixed constant voltage irrespective of the loading on the device, power supply variations, temperature changes, and the passage of time. Voltage references are used in power supply voltage regulator s, analog to digital converter s and digital to analog converter s, and myriad other measurement and control systems. Voltage references vary widely in performance a regulator for a computer power supply may only hold its value to within a few per cent of the nominal value, whereas laboratory voltage standards have precisions and stability measured in parts per million .

Multiple issues tone August 2008 unreferenced August 2008 The Creditor Reference also called the Structured Creditor Reference is an international business standard based on International Organization for Standardization ISO 11649, implemented at the end of 2008. Using Creditor Reference, a company can automatically match its remittance information to its accounts receivable A R . This means that the company s financial supply chain s Straight through processing STP will be increased. The Creditor Reference was first implemented within the Single Euro Payments Area SEPA rulebook 3.2. Implementation A vendor adds the Creditor Reference to its invoices. When a customer pays the invoice, the company writes the Creditor Reference instead of the invoice number in the message section, or places a Creditor Reference field in its payment ledger. When the vendor receives the payment, it can automatically match the remittance information to its Accounts Receivable system. Structure The Creditor Reference is an alphanumeric string, 25 characters long, with the letters RF at the beginning. After the letters are two check digits, which confirm that the reference will be entered correctly. The remaining part of the Creditor Reference up to 21 alphanumeric characters is the Reference. The content of the Creditor Reference can be determined without any restrictions.

A reference card or quick reference card is a concise bundling of common syntax syntactic rules and idiom s of a particular formal language . It serves as an ad hoc memory aid for an experienced user . In spite of what the name reference card suggest, the term only tends to be used in the narrow context of programming language s or markup language s. However, this concept is now being adopted to portray concise information in many other fields. Appearance Due to its logical structure and conciseness, finding information in a reference card is trivial for humans and requires no computer interaction. It is therefore convenient for a user to printing print out a reference card. This in contrast to user guide s, which tend to be large & verbose and to have a very low information density in comparison to reference cards .
