- principal quantum number — the nonnegative, integral quantum number that defines the stationary orbits in the Bohr model of the atom.
- programmable array logic — (hardware) (PAL) A family of fuse-programmable logic integrated circuits originally developed by MMI. Registered or combinatorial output functions are modelled in a sum of products form. Each output is a sum (logical or) of a fixed number of products (logical and) of the input signals. This structure is well suited for automatic generation of programming patterns by logic compilers. PAL devices are programmed by blowing the fuses permanently using overvoltage. Today, more complex devices based on the same original architecture are available (CPLD's for Complex PLD's) that incorporate the equivalent of several original PAL chips. PAL chips are, however, still popular due to their high speed.

- 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.
