This command checks a disk and displays a status report.

A function contained within a class is called a member function.

NTFS (New Technology File System) is a proprietary file system developed by Microsoft Corporation for its Windows NT line of operating systems, beginning with Windows NT 3.1 and Windows 2000, including Windows XP, Windows Server 2003, and all their successors to date.

The World Wide Web is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks.

A tuple is one record (one row).

X.25 defines a standard protocol for information exchange in packet mode between a DTE and a DCE (that is, between an individual user's equipment and the network provider's equipment).

The program counter (PC) is a processor register that indicates where a computer is in its program sequence.

A queue is a First-In-First-Out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed.. A queue is an example of a linear data structure, or more abstractly a sequential collection.

BFS algorithm uses a queue data structure to store intermediate results as it traverses the graph.

This command is used for modifying the structure of an existing database. Changes like adding a new column, removing an existing column, changing the size of an existing column, etc. can be made by using this command.

The translation process moves all points of an object at a fixed distance in a specified direction.

The most common application of recursion is in mathematics and computer science, in which it refers to a method of defining functions in which the function being defined is applied within its own definition. Specifically this defines an infinite number of instances (function values), using a finite expression that for some instances may refer to other instances, but in such a way that no loop or infinite chain of references can occur.

In object-oriented programming, operator overloading—less commonly known as operator ad-hoc polymorphism—is a specific case of polymorphism, where different operators have different implementations depending on their arguments. Operator overloading is generally defined by the language, the programmer, or both.

The Abstract Window Toolkit (AWT) is Java's original platform-independent windowing, graphics, and user-interface widget toolkit. The AWT is now part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program. AWT is also the GUI toolkit for a number of Java ME profiles.

Systems analysis phase defines project goals into defined functions and operation of the intended application. It analyzes end-user information needs.
