- pre-emptive multitasking — (operating system, parallel) A type of multitasking where the scheduler can interrupt and suspend ("swap out") the currently running task in order to start or continue running ("swap in") another task. The tasks under pre-emptive multitasking can be written as though they were the only task and the scheduler decides when to swap them. The scheduler must ensure that when swapping tasks, sufficient state is saved and restored that tasks do not interfere. The length of time for which a process runs is known as its "time slice" and may depend on the task's priority or its use of resources such as memory and I/O. This contrasts with cooperative multitasking where each task must include calls to allow it to be descheduled periodically.

- virtual storage extended — (operating system) (VSE, formerly DOS/VSE) is a multitasking, IBM 370-architected operating system similar to Multiple Virtual Storage (MVS). VSE run jobs in partitions rather than address spaces, and uses POWER for input/output rather than JES, but is largely similar to MVS. Subsequent VSE/ESA releases gave VSE the XA-370 channel architecture, 31-bit virtual and real storage support, and data spaces. VSE is the IBM operating system on one-third of installed IBM 4381s and a significant proportion of IBM 9370s as well. It offers transaction processing and batch processing capabilities well beyond Virtual Machine's current capabilities, and has a close affinity with MVS.
- 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.
- volume table of contents — (storage) (VTOC) /V-tock/ A special file on a disk, which contains a list of all the ordinary files on the disk and their addresses. Also called a directory.

- 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.
