  2. Orders of magnitude (data) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(data)

    5 bits – the size of code points in the Baudot code, used in telex communication (a.k.a. pentad) 6 bits – the size of code points in Univac Fieldata, in IBM "BCD" format, and in Braille. Enough to uniquely identify one codon of genetic code. The size of code points in Base64; thus, often the entropy per character in a randomly-generated ...

  3. Course allocation - Wikipedia

    en.wikipedia.org/wiki/Course_allocation

    Course allocation is the problem of allocating seats in university courses among students. Many universities impose an upper bound on the number of students allowed ...

  4. Coding tree unit - Wikipedia

    en.wikipedia.org/wiki/Coding_tree_unit

    A CTB can be 64×64, 32×32, or 16×16 with a larger pixel block size usually increasing the coding efficiency. [4] CTBs are then divided into one or more coding units (CUs), so that the CTU size is also the largest coding unit size. [4] The arrangement of CUs in a CTB is known as a quadtree since a subdivision results in four smaller regions. [4]

  5. Resource acquisition is initialization - Wikipedia

    en.wikipedia.org/wiki/Resource_acquisition_is...

    Resource management therefore needs to be tied to the lifespan of suitable objects in order to gain automatic allocation and reclamation. Resources are acquired during initialization, when there is no chance of them being used before they are available, and released with the destruction of the same objects, which is guaranteed to take place ...

  6. Stride of an array - Wikipedia

    en.wikipedia.org/wiki/Stride_of_an_array

    In computer programming, the stride of an array (also referred to as increment, pitch or step size) is the number of locations in memory between beginnings of successive array elements, measured in bytes or in units of the size of the array's elements. The stride cannot be smaller than the element size but can be larger, indicating extra space ...

  7. Disk sector - Wikipedia

    en.wikipedia.org/wiki/Disk_sector

    In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories.To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.

  8. Java BluePrints - Wikipedia

    en.wikipedia.org/wiki/Java_BluePrints

    There have been three Java BluePrints books, and the Core Java EE design patterns which are hosted on the Java BluePrints site have become the standard lingua for Java EE application development. [2] Java BluePrints was the first source to promote Model View Controller (MVC) and Data Access Object (DAO) for Java EE application development.

  9. Java performance - Wikipedia

    en.wikipedia.org/wiki/Java_performance

    Java memory use is much higher than C++'s memory use because: There is an overhead of 8 bytes for each object and 12 bytes for each array [61] in Java. If the size of an object is not a multiple of 8 bytes, it is rounded up to next multiple of 8. This means an object holding one byte field occupies 16 bytes and needs a 4-byte reference.
