CMD640
CMD640, the CMD Technology Inc product 0640, is an IDE interface chip for the PCI and VLB buses. CMD640 had some sort of hardware acceleration: WDMA and Read-Ahead (prefetch) support.
CMD Technology Inc was acquired by Silicon Image Inc. in 2001.
Hardware bug
The original CMD640 has a data corruption bug. The data corruption bug is similar to the bug affecting the contemporaneous PC Tech RZ1000 chipset. Both chipsets were used on a number of motherboards, including those from Intel.
Мodern operating systems have a workaround for this bug by prohibiting aggressive acceleration mode and losing about 10% of the performance.

Batch file
A batch file is a kind of script file in DOS, OS/2 and Windows. It consists of a series of commands to be executed by the command line interpreter, stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as "if", "for", "goto" and labels.
Similar to Job Control Language (JCL) and other systems on mainframe and minicomputer systems, batch files were added to ease the work required for certain regular tasks by allowing the user to set up a script to automate them. When a batch file is run, the shell program (usually COMMAND.COM or cmd.exe) reads the file and executes its commands, normally line-by-line.Unix-like operating systems (such as Linux) have a similar, but more flexible, type of file called a shell script.
The filename extension .bat is used in DOS and Windows. Windows NT and OS/2 also added .cmd. Batch files for other environments may have different extensions, e.g. .btm in 4DOS, 4OS2 and 4NT related shells.

Stratigraphic unit
A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.
Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".
Lithostratigraphic units
Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.
Bed
A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.
Member
A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.
1994 Group
The 1994 Group was a coalition of smaller research-intensive universities in the United Kingdom, founded in 1994 to defend these universities' interests following the creation of the Russell Group by larger research-intensive universities earlier that year. The 1994 Group originally represented seventeen universities, rising to nineteen, and then dropping to eleven. The Group started to falter in 2012, when a number of high performing members left to join the Russell Group. The 1994 Group ultimately dissolved in November 2013.
Role
The group sought "to represent the views of its members on the current state and the future of higher education through discussions with the government, funding bodies, and other higher education interest groups" and "[made] its views known through its research publications and in the media".
University Alliance, million+, GuildHE and the Russell Group were its fellow university membership groups across the UK higher education sector.
