- antivirus software — (tool) Programs to detect and remove computer viruses. The simplest kind scans executable files and boot blocks for a list of known viruses. Others are constantly active, attempting to detect the actions of general classes of viruses. antivirus software should always include a regular update service allowing it to keep up with the latest viruses as they are released.
- bioinstrumentation — the use of instruments, as sensors, to detect and measure certain body functions, as of persons in spaceflight, and transmit the data to a point where it is evaluated
- branch instruction — a machine-language or assembly-language instruction that causes the computer to branch to another instruction
- brute force attack — (cryptography) A method of breaking a cipher (that is, to decrypt a specific encrypted text) by trying every possible key. The quicker the brute force attack, the weaker the cipher. Feasibility of brute force attack depends on the key length of the cipher, and on the amount of computational power available to the attacker. Brute force attack is impossible against the ciphers with variable-size key, such as a one-time pad cipher.
- camel's-hair brush — an artist's small brush, made of hair from a squirrel's tail
- children's crusade — a crusade to recover Jerusalem from the Saracens, undertaken in 1212 by thousands of French and German children who perished, were sold into slavery, or were turned back.
- coitus interruptus — the deliberate withdrawal of the penis from the vagina before ejaculation
- composition rubber — manufactured rubber
- construction paper — Construction paper is a type of stiff, colored paper that children use for drawing and for making things.
- constructive proof — (mathematics) A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.
- crude oil desalter — A crude oil desalter is equipment which removes inorganic salts from crude oil, using chemical or electrostatic separation.
- crude oil fraction — A crude oil fraction is a component of crude oil, which has its own particular molecular composition, weight, and boiling point.
- dafydd ap gruffudd — died 1283, Welsh leader. Claiming the title Prince of Wales (1282), he led an unsuccessful revolt against Edward I: executed
- de bruijn notation — (language) A variation of lambda notation for specifying functions using numbers instead of names to refer to formal parameters. A reference to a formal parameter is a number which gives the number of lambdas (written as \ here) between the reference and the lambda which binds the parameter. E.g. the function \ f . \ x . f x would be written \ . \ . 1 0. The 0 refers to the innermost lambda, the 1 to the next etc. The chief advantage of this notation is that it avoids the possibility of name capture and removes the need for alpha conversion.
- debt restructuring — Debt restructuring is a method of organizing a company's debts in a different way in order to make the company more likely to be able to pay them.
- destruct mechanism — a mechanism that causes the destruction of a rocket or missile when activated

- drug-eluting stent — A drug-eluting stent is a tube placed into a blocked artery that slowly releases a drug to prevent another blockage in the artery.
- earned run average — a measure of the effectiveness of a pitcher, obtained by dividing the number of earned runs scored against the pitcher by the number of innings pitched and multiplying the result by nine. A pitcher yielding three earned runs in nine innings has an earned run average of 3.00. Abbreviation: ERA, era.
- eighty-twenty rule — (programming) The program-design version of the law of diminishing returns. The 80/20 rule says that roughly 80% of the problem can be solved with 20% of the effort that it would take to solve the whole problem. For example, parsing e-mail addresses in "From:" lines in e-mail messages is notoriously difficult if you follow the RFC 2822 specification. However, about 60% of actual "From:" lines are in the format "From: Their Name <[email protected]>", with a far more constrained idea of what can be in "user" or "host" than in RFC 2822. Another 25% just add double-quotes around "Their Name". Matching just those two patterns would thus cover 85% of "From:" lines, with a tiny portion of the code required to fully implement RFC2822. (Adding support for "From: [email protected]" and "From: [email protected] (Their Name) " brings coverage to almost 100%, leaving only really baroque things that RFC-2822 permits, like "From: Pete(A wonderful \) chap)

- ninety-ninety rule — (humour) "The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time". An aphorism attributed to Tom Cargill of Bell Labs, and popularised by Jon Bentley's September 1985 "Bumper-Sticker Computer Science" column in "Communications of the ACM". It was there called the "Rule of Credibility", a name which seems not to have stuck.
