A reference is an abstract data type and may be implemented in many ways. Typically, a reference refers to data stored in memory on a given system, and its internal value is the memory address of the data, i.e. a reference is implemented as a pointer. For this reason a reference is often said to "point to" the data.
In computer programming, an indirection (also called a reference) is a way of referring to something using a name, reference, or container instead of the value itself. The most common form of indirection is the act of manipulating a value through its memory address. For example, accessing a variable through the use of a pointer.
A pointer is a programming concept used in computer science to reference or point to a memory location that stores a value or an object. It is essentially a variable that stores the memory address of another variable or data structure rather than storing the data itself.
In computer science, references are data types that refer to an object elsewhere in memory and are used to construct a wide variety of data structures, such as linked lists. Generally, a reference is a value that enables a program to directly access the particular data item. Most programming languages support some form of
In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, or heap references, can point to which variables, or storage locations. It is often a component of more complex analyses such as escape analysis. A closely related technique is shape analysis.
In computer science, locality of reference, also known as the principle of locality, [1] is the tendency of a processor to access the same set of memory locations repetitively over a short period of time. [2] There are two basic types of reference locality – temporal and spatial locality.
A programmer, computer programmer, or coder is a person who writes computer software. The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. One who practices or professes a formal approach to programming may also be known as a programmer analyst.
The Internet allows computer users to remotely access other computers and information stores easily from any access point. Access may be with computer security; i.e., authentication and encryption technologies, depending on the requirements.
