Big O notation
In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.

Blood type
A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteinscarbohydratesglycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens can stem from one allele (or very closely linked genes) and collectively form a blood group system. Blood types are inherited and represent contributions from both parents. A total of 32 human blood group systems are now recognized by the International Society of Blood Transfusion (ISBT). The two most important ones are ABO and the RhD antigen; they determine someone's blood type (A, B, AB and O, with + and - denoting RhD status).

Breve
A breve (; ; from the Latin brevis “short, brief”) is the diacritical mark ˘, shaped like the bottom half of a circle. As used in Ancient Greek, it is also called micron and vrachy or brachy. It resembles the caron (the wedge or háček in Czech), but is rounded, while the caron has a sharp tip. Compare Ǎ ǎ Ě ě Ǐ ǐ Ǒ ǒ Ǔ ǔ (caron) with Ă ă Ĕ ĕ Ĭ ĭ Ŏ ŏ Ŭ ŭ (breve).

Caron
A caron ( ˇ ) or háček (; from Czech háček ), also known as a wedge, inverted circumflex, inverted hat, is a diacritic placed over certain letters to indicate present or historical palatalizationiotation, or postalveolar pronunciation in the orthography of some BalticSlavicFinno-Lappic, and other languages. The caron also indicates the third tone (falling and then rising) in the Pinyin romanization of Mandarin Chinese.

Circumflex
The circumflex is a diacritic in the LatinGreek and Cyrillic scripts that is used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from Latin circumflexus 'bent around' – a translation of the Greek περισπωμένη (perispōménē). The circumflex in the Latin script is chevron-shaped ( ˆ ), while the Greek circumflex may be displayed either like a tilde ( ˜ ) or like an inverted breve (   ̑ ).

Double acute accent
The double acute accent ( ˝ ) is a diacritic mark of the Latin script. It is used primarily in written Hungarian, and consequently is sometimes referred to as Hungarumlaut, a portmanteau of Hungarian umlaut. The signs formed with diacritic marks are letters in their own right in the Hungarian alphabet (for instance, they are separate letters for the purpose of collation).

Emoticon
An emoticon is a metacommunicative pictorial representation of a facial expression which in the absence of body language and prosody serves to draw a receiver's attention to the tenor or temper of a sender's nominal verbal communication, changing and improving its interpretation. It expresses—usually by means of punctuation marks—a person's feelings or mood and can include numbers and letters, as well. These emoticons are usually flipped sideways. In the most recent years, as social media has become widespread, emoticons have played a significant role in communication through technology. These emoticons offer another range of "tone" and feeling through texting that portrays specific emotions through facial gestures while in the midst of cyber communication.

Empty set
In mathematics, and more specifically set theory, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories assure that the empty set exists by including an axiom of empty set; in other theories, its existence can be deduced. Many possible properties of sets are trivially true for the empty set.

List of emoticons
This is a list of notable and commonly used emoticons or textual portrayals of a writer's mood or facial expression in the form of icons. The Western use of emoticons is quite different from Eastern usage, and Internet forums, such as 2channel, typically show expressions in their own ways. In recent times, graphic representations, both static and animated, have taken the place of traditional emoticons in the form of icons.

Macron
A macron (, ), , is a diacritic placed above a vowel (and, more rarely, under or above a consonant). It was originally used to mark a long or heavy syllable in Greco-Roman metrics, but now marks a long vowel. In the International Phonetic Alphabet the macron is used to indicate mid tone; the sign for a long vowel is a modified triangular colon .

Object file
An object file is a file containing object code, meaning relocatable format machine code that is usually not directly executable. Object files are produced by an assemblercompiler, or other language translator, and used as input to the linker, which in turn typically generates an executable or library by combining parts of object files. There are various formats for object files, and the same object code can be packaged in different object files.

Ogonek
The ogonek (Polish: , "little tail", the diminutive of ogon; ) is a diacritic hook placed under the lower right corner of a vowel in the Latin alphabet used in several European languages, and directly under a vowel in several Native American languages.

Shift Out and Shift In characters
Shift Out (SO) and Shift In (SI) are ASCII control characters 14 and 15, respectively (0x0E and 0x0F.)  The original meaning of those characters provided a way to shift, hence the nomenclature, a coloured ribbon, split longitudinally usually with red and black, up and down to the other colour in an electro-mechanical typewriter or teleprinter to automate the same function of manual typewriters. Black was the conventional ambient default colour and so was shifted "in" or "out" with the other colour on the ribbon. Later advancements in technology, such as the IBM Selectric typewriter, instigated use of this function for switching to a different font or character set and back.  This was used, for instance, in the Russian character set known as KOI7, where SO starts printing Russian letters, and SI starts printing Latin letters again. SO/SI control characters also are used to display VT-100 pseudographics, and emoji (Japanese picture icons) on SoftBank MobileISO/IEC 2022 standard specifies their generalized usage.
