- portable document format — (file format) (PDF) The native file format for Adobe Systems' Acrobat. PDF is the file format for representing documents in a manner that is independent of the original application software, hardware, and operating system used to create those documents. A PDF file can describe documents containing any combination of text, graphics, and images in a device-independent and resolution independent format. These documents can be one page or thousands of pages, very simple or extremely complex with a rich use of fonts, graphics, colour, and images.

- recursive descent parser — (grammar) A "top-down" parser built from a set of mutually-recursive procedures or a non-recursive equivalent where each such procedure usually implements one of the productions of the grammar. Thus the structure of the resulting program closely mirrors that of the grammar it recognises.
- referential transparency — (programming) An expression E is referentially transparent if any subexpression and its value (the result of evaluating it) can be interchanged without changing the value of E. This is not the case if the value of an expression depends on global state which can change value. The most common example of changing global state is assignment to a global variable. For example, if y is a global variable in: f(x) { return x+y; } g(z) { a = f(1); y = y + z; return a + f(1); } function g has the "side-effect" that it alters the value of y. Since f's result depends on y, the two calls to f(1) will return different results even though the argument is the same. Thus f is not referentially transparent. Changing the order of evaluation of the statements in g will change its result. We could make f above referentially transparent by passing in y as an argument: f(x, y) = x+y Similarly, g would need to take y as an argument and return its new value as part of the result: g(z, y) { a = f(1, y); y' = y+z; return (a + f(1, y'), y'); } Referentially transparent programs are more amenable to formal methods and easier to reason about because the meaning of an expression depends only on the meaning of its subexpressions and not on the order of evaluation or side-effects of other expressions. We can stretch the concept of referential transparency to include input and output if we consider the whole program to be a function from its input to its output. The program as a whole is referentially transparent because it will always produce the same output when given the same input. This is stretching the concept because the program's input may include what the user types, the content of certain files or even the time of day. If we do not consider global state like the contents of files as input, then writing to a file and reading what was written behaves just like assignment to a global variable. However, if we must consider the state of the universe as an input rather than global state then any deterministic system would be referentially transparent! See also extensional equality, observational equivalence.

- visual component library — (programming) VCL A application framework library for Microsoft Windows and Borland Software Corp.'s Delphi and C++Builder rapid application development software. VCL was originally designed for Delphi but is now also used for C++Builder. This replaces OWL Object Windows Library as Borland's Windows C++ framework of choice. VCL encapsulates the C-based Win32 API into a much easier to use, object-oriented form. Like its direct rival, Microsoft Foundation Class Library (MFC), VCL includes classes to create Windows programs. The VCL component class can be inherited to create new VCL components, which are the building blocks of Delphi and C++Builder applications. VCL components are somewhat in competition with ActiveX controls, though a VCL wrapper can be created to make an ActiveX control seem like a VCL component.
- wired equivalent privacy — (networking, standard) (WEP) IEEE 802.11:1999. A cryptographic privacy algorithm, based on the RC4 encryption engine, used to provide confidentiality for 802.11 wireless networks. WEP is intended to provide roughly the same level of confidentiality for wireless data as a wired LAN (Ethernet), which is NOT protected by encryption. WEP is often wrongly expanded as "Wireless Encryption Protocol". WEP is a protocol that provides encryption used on wireless networks but that's not what it stands for.
