It featured a similar hardware and software specification to the earlier C860 model ; the key differences were that it only had 16 MB of flash memory yet gained an internal 4 GB microdrive ( Hitachi ) instead, a USB Host port, and " lost " the serial port ( in some cases the components were not fitted to the motherboard or were incapable of driving the regular serial adaptor cables ).

* Hardware abstraction layer, a layer of software that hides hardware differences from higher level programs

The GeForce 4 Ti was very similar to its predecessor ; the main differences were higher core and memory speeds, a revised memory controller, improved vertex and pixel shaders, hardware anti-aliasing and DVD playback.

It was very similar to its predecessor ; the main differences were higher core and memory clock rates, a revised memory controller ( known as Lightspeed Memory Architecture II ), updated pixel shaders, an additional vertex shader ( the vertex and pixel shaders were now known as nFinite FX Engine II ), hardware anti-aliasing ( Accuview AA ), and DVD playback.

This x86 measurement attempts to even out these hardware differences.

Its function is to hide differences in hardware from most of the operating system kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardware.

Applying patches to firmware poses special challenges: re-embedding typically small code sets on hardware devices often involves the provision of totally new program code, rather than simply of differences from the previous version.

Development then shifted to emulating Atari's Asteroids, but hardware differences between Asteroids and Defenders proposed specifications were problematic.

These lists play multiple games between engines on standard hardware platforms, so that processor differences are factored out.

IBM support included customer service and hardware circuit modifications needed to tabulate numbers, create mathematical tables, add, subtract, multiply, reproduce, verify, create tables of differences, create tables of logarithms and perform Lagrangian interpolation, all to solve differential equations for astronomical applications.

This way he would know exactly how the pieces would sound on the system's hardware instead of having to deal with audio hardware differences between the original MIDI sampler and the Super Nintendo.

The Old English versions of Orosius's Histories against the Pagans and Bede's Ecclesiastical History of the English People are no longer accepted by scholars as Alfred's own translations because of lexical and stylistic differences.

This discovery has shed much light on the differences between the two versions ; while it was previously maintained that the Greek Septuagint ( the version used by the earliest Christians ) was only a poor translation, professor Emanuel Tov, senior editor of the Dead Sea Scrolls ' publication, wrote that the Masoretic edition either represents a substantial rewriting of the original Hebrew, or there had previously been two different versions of the text.

Both the Mawangdui and Guodian versions are generally consistent with the received texts, excepting differences in chapter sequence and graphic variants.

* The Annotated MUMPS Language Standard, showing the evolution of the language and differences between versions of the ANSI standard.

Therefore, all significant versions of predestination account for the differences between people ( perhaps in life or, in death, or both ) by reference to the will of the Creator.

For a detailed description of the differences between 2. x and 3. x versions, see History of Python.

Because different vendors of Unix systems ( and in many cases, different versions of the Unix software ) implemented slightly different behavior and names for important functions, a system administrator was required to have sufficient programming expertise to edit the source code before building the program executables to account for these differences.

Several albums exist in 2 versions, the original Japanese version and the international version, each having differences in tracklistings.

From the late 1980s a new school of linguistic relativity scholars have examined the effects of differences in linguistic categorization on cognition, finding broad support for weak versions of the hypothesis in experimental contexts.

What was perhaps most significant for the LXX, as distinct from other Greek versions, was that the LXX began to lose Jewish sanction after differences between it and contemporary Hebrew scriptures were discovered ( see above ).

Most of these are slight differences in the wording of the prayers ; for instance, Oriental Sephardic and some Hasidic prayer books state " חננו מאתך חכמה בינה ודעת ", " Graciously bestow upon us from You wisdom ( ḥochmah ), understanding ( binah ) and knowledge ( daat )", in allusion to the Kabbalistic sefirot of those names, while the Nusach Ashkenaz, as well as Western Sephardic and other Hasidic versions retain the older wording " חננו מאתך דעה בינה והשכל ", " Graciously bestow upon us from You knowledge, understanding, and reason ".

There are several versions of the text of the Second Amendment, each with slight capitalization and punctuation differences, found in the official documents surrounding the adoption of the Bill of Rights.

Most of this article is applicable to both XSLT versions ; any differences are noted in the text.

Notable differences from the third and later versions include:

After the composer's death the score was subject to significant amendment, including the introduction of recitative in place of the original dialogue ; there is no standard edition of the opera, and differences of view exist as to what versions best express Bizet's intentions.

Because of the differences in the European PAL and USA's NTSC systems two main versions of DOCSIS exist, DOCSIS and EuroDOCSIS.

The differences between these versions are significant.

; Delta compression: Most revision control software uses delta compression, which retains only the differences between successive versions of files.

Historically, the substantive and editorial differences among the first-edition and the third-edition versions is that the former, A Dictionary of Modern English Usage ( 1926 ), is a prescriptive style guide to clear and expressive writing, whilst the latter versions, The New Fowler ’ s Modern English Usage ( 1996 ) and Fowler ’ s Modern English Usage ( 2004 ), are descriptive usage guides to spoken and written English.

It was used much in the same way by later scholars to mark differences between various translations or versions of the Bible and other manuscripts.
