HP Universal Print Driver (UPD) is an intelligent print driver that supports a broad range of HP print devices, such as LaserJet and various MFPs. Developed by Hewlett-Packard , HP UPD combines a general purpose driver ( XPSDrv , UniDrv , or PSCRIPT ), print control, and HP proprietary extensions.
Driver Verifier is a tool included in Microsoft Windows that replaces the default operating system subroutines with ones that are specifically developed to catch device driver bugs. [1] Once enabled, it monitors and stresses drivers to detect illegal function calls or actions that may be causing system
The drivers which work properly in normal circumstances can go wrong in rare and exceptional cases and the traditional testing techniques may not help in detecting the corner case behavior of the drivers. The wave of verification of device drivers was initiated by Microsoft through their SLAM project as early as the year 2000. The motivation ...
Drivers that may be vulnerable include those for WiFi and Bluetooth, [20] [21] gaming/graphics drivers, [22] and drivers for printers. [ 23 ] There is a lack of effective kernel vulnerability detection tools, especially for closed-source OSes such as Microsoft Windows [ 24 ] where the source code of the device drivers is mostly proprietary and ...
This allowed those Macs to support 64-bit processes while still supporting 32-bit device drivers; although not 64-bit drivers and performance advantages that can come with them. Mac OS X 10.7 "Lion" ran with a 64-bit kernel on more Macs, and OS X 10.8 "Mountain Lion" and later macOS releases only have a 64-bit kernel. On systems with 64-bit ...

Software verification is a discipline of software engineering, programming languages, and theory of computation whose goal is to assure that software satisfies the expected requirements. Broad scope and classification
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results. In ...
