"Compatibility View" is a compatibility mode feature of the web browser Internet Explorer in version 8 and later. When active, Compatibility View forces IE to display the webpage in Quirks mode as if the page were being viewed in IE7. [1] [2] When compatibility view is not activated, IE is said to be running in native mode. In IE11, a user can ...
JIT causes a slight to noticeable delay in the initial execution of an application, due to the time taken to load and compile the input code. Sometimes this delay is called "startup time delay" or "warm-up time". In general, the more optimization JIT performs, the better the code it will generate, but the initial delay will also increase.
Software compatibility can refer to the compatibility that a particular software has running on a particular CPU architecture such as Intel or PowerPC. [1] Software compatibility can also refer to ability for the software to run on a particular operating system. Very rarely is a compiled software compatible with multiple different CPU ...
The Common Language Runtime (CLR), the virtual machine component of Microsoft.NET Framework, manages the execution of .NET programs. Just-in-time compilation converts the managed code (compiled intermediate language code) into machine instructions which are then executed on the CPU of the computer. [1]
Compatibility testing is normally required for PC titles, nearing the end of development as much of the compatibility depends on the final build of the game. [ citation needed ] Often two rounds of compatibility tests are done - early in beta to allow time for issue resolution, and late in beta or during release candidate .
During the Windows 2000, XP, 2003 timeframe there was an old tool Hardware Compatibility Test (HCT) to certify devices. When Windows Vista was released the tool was replaced by Driver Test Manager (DTM) which can certify drivers for all then-supported platforms. At that time DTM was part of Windows Driver Kit (WDK).
[7] [8] The key innovation was just-in-time compilation (JIT), which Mozilla had also been working on for SpiderMonkey. [9] Because of V8's performance, the other browser vendors needed to overhaul their engines for JIT. [10] Apple developed the Nitro engine for its Safari browser, which had 30% better performance than its predecessor. [11]
During compilation of CLI programming languages, the source code is translated into CIL code rather than into platform- or processor-specific object code.CIL is a CPU- and platform-independent instruction set that can be executed in any environment supporting the Common Language Infrastructure, such as the .NET runtime on Windows, or the cross-platform Mono runtime.
