LC-3
Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language. It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a theoretically viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages. These features make it useful for beginning instruction, so it is most often used to teach fundamentals of programming and computer architecture to computer science and computer engineering students. The LC-3 was developed by Yale N. Patt at the University of Texas at Austin and Sanjay J. Patel at the University of Illinois at Urbana–Champaign. Their specification of the instruction set, the overall architecture of the LC-3, and a hardware implementation can be found in the second edition of their textbook. Courses based on the LC-3 and Patt and Patel's book are offered in many computer engineering and computer science departments.

Java Card Open Platform
Java Card OpenPlatform (JCOP) is a smart card operating system for the Java Card platform developed by IBM Zürich Research Laboratory. On 31 January 2006 the development and support responsibilities transferred to the IBM Smart Card Technology team in Böblingen, Germany . Since July 2007 support and development activities for the JCOP operating system on NXP / Philips silicon are serviced by NXP Semiconductors. The title originates from the standards it complies with: A Java Card JCOP has a Java Card Virtual Machine (JCVM) which allows it to run applications written in Java programming language.

Feit–Thompson Theorem
In mathematics, the Feit–Thompson theorem, or odd order theorem, states that every finite group of odd order is solvable. It was proved by Walter Feit and John Griggs Thompson (1962, 1963).

Cataloging
In library and information science, cataloging (US) or cataloguing (UK) is the process of creating metadata representing information resources, such as books, sound recordings, moving images, etc. Cataloging provides information such as creator names, titles, and subject terms that describe resources, typically through the creation of bibliographic records. The records serve as surrogates for the stored information resources. Since the 1970s these metadata are in machine-readable form and are indexed by information retrieval tools, such as bibliographic databases or search engines. While typically the cataloging process results in the production of library catalogs, it also produces other types of discovery tools for documents and collections. Bibliographic control provides the philosophical basis of cataloging, defining the rules for sufficiently describing information resources to enable users to find and select the most appropriate resource. A cataloger is an individual responsible for the processes of description, subject analysis, classification, and authority control of library materials. Catalogers serve as the "foundation of all library service, as they are the ones who organize information in such a way as to make it easily accessible".

Windows Defender
Microsoft Defender (known as Windows Defender before Windows 10 November 2019 Update or Windows Defender Antivirus in Windows 10 Creators Update and later) is an anti-malware component of Microsoft Windows. It was first released as a downloadable free anti-spyware program for Windows XP, and was later shipped with Windows Vista and Windows 7. It has evolved into a full antivirus program, replacing Microsoft Security Essentials as part of Windows 8 and later versions.

Determining Number of Clusters in a Data Set
For a certain class of clustering algorithms (in particular k-means, k-medoids and expectation–maximization algorithm), there is a parameter commonly referred to as k that specifies the number of clusters to detect. Other algorithms such as DBSCAN and OPTICS algorithm do not require the specification of this parameter; hierarchical clustering avoids the problem altogether. The correct choice of k is often ambiguous, with interpretations depending on the shape and scale of the distribution of points in a data set and the desired clustering resolution of the user. In addition, increasing k without penalty will always reduce the amount of error in the resulting clustering, to the extreme case of zero error if each data point is considered its own cluster (i.e., when k equals the number of data points, n). Intuitively then, the optimal choice of k will strike a balance between maximum compression of the data using a single cluster, and maximum accuracy by assigning each data point to its own cluster. If an appropriate value of k is not apparent from prior knowledge of the properties of the data set, it must be chosen somehow. There are several categories of methods for making this decision.

Microsoft Realtime Compression Interface
DriveSpace (initially known as DoubleSpace) is a disk compression utility supplied with MS-DOS starting from version 6.0 in 1993 and ending in 2000 with the release of Windows Me. The purpose of DriveSpace is to increase the amount of data the user could store on disks by transparently compressing and decompressing data on-the-fly. It is primarily intended for use with hard drives, but use for floppy disks is also supported. This feature was removed in Windows XP and later.

Mo Siang Online
Mo Siang Online is an MMORPG based on the warring states of ancient China . The game is mainly focused on Martial Arts and Kung Fu, allowing each character to choose 6 fighting styles. At present, Mo Siang only has five English servers and eight Chinese servers with their own language interface.The Korean game developer once released its global server and renamed this game as Titan, but this game used to be called as Dark Story in Korea with its Korean server. In Japan, Mo Siang is called Feats of Arms. After the agent in Japan is replaced, this game is renamed as Crest of Jade. The Japanese game distributor run its Beta on 19th Feb. 2009. From August 2009 on, there is another English version of Mo Siang released, the game agent PlayOMG renames this game as Azuga, Age of Chaos. On the contrary, from September 2009 on, the Japanese game agent of Mo Siang decides to close their server.
