For example, run-length encoding replaces strings of repeated characters or other units of data with a single character and a count. Computers can perform complex and repetitive procedures quickly, precisely and reliably and can store and retrieve large amounts of data. Most computers in use today are electronic digital computers as opposed to analogue computers. A notional unit of computing power combining execution speed and storage capacity. That machine can't run GNU Emacs, it doesn't have enough computrons!
It uses the 'handshake' and 'unit' constructs. The concentrator's output bandwidth must be at least as great as the total bandwidth of all simultaneously active inputs.
A concentrator is one kind of multiplexing device. A conceptualisation is an abstract, simplified view of the world that we wish to represent. For example, we may conceptualise a family as the set of names, sexes and the relationships of the family members. Choosing a conceptualisation is the first stage of knowledge representation. A conceptualisation is a high-level data model. ConCoord supports explicit parallelism with different granularity. CONCUR was inspired by Modula but removes Modula's restrictions on the placement of process declarations and invocations in order to study the implications of process support more fully.
The protective plastic bag that accompanies 3. Rarely, also used of paper disk envelopes. Unlike the write protect tab, the condom when left on not only impedes the practice of SEX but has also been shown to have a high failure rate as drive mechanisms attempt to access the disk - and can even fatally frustrate insertion. Conflation algorithms are used in databases. Typically this will result in some packets being delayed, thus increasing the average latency. It allowed multiple database contexts with hypothetical assertions.

In times past, the console was a privileged location that conveyed godlike powers to anyone with fingers on its keys. Under Unix and other modern time-sharing operating systems, such privileges are guarded by passwords instead, and the console is just the tty the system was booted from. In object-oriented languages, a function provided by a class to initialise a newly created object. The constructor function typically has the same name as the class. It may take arguments, e. Consul's fundamental data type is the set and its fundamental operators are the logical connectives and, or, not and quantifiers forall, exists.
It is written in Lisp-like syntax, e. Consultants perform business requirements analysis, recommend selection of packaged software, develop proposals for consulting services and manage implementation projects at client sites. If the syntax of a symbol is independent of its context, the grammar is a context-free grammar. A disk controller is used to connect hard disks and floppy disks, a network controller is used for Ethernet. Other controllers are: keyboard controller, interrupt controller and graphics controller.
Concurrent Object-Oriented Language. Commonly used coordinate systems have as many coordinates as their are dimensions in the space, e. The most common coordinate system is Cartesian coordinates, probably followed by polar coordinates. Used to describe an instance of a copy-protected program that has been broken; that is, a copy with the copy-protection scheme disabled or removed. Class Oriented Ring Associated Language. Simple language for student math problems.
This term dates from the days of ferrite core memory and, like the technology, is now archaic. Cray Operating System. See commercial software. A countable set has countably many elements.

If the isomorphism is stated explicitly then the set is called a counted set or an enumeration. There are two types of coupling, tight and loose. Loose coupling is desirable for good software engineering but tight coupling may be necessary for maximum performance. Coupling is increased when the data exchanged between components becomes larger or more complex. It is reported that at Sun this word is often said with reverence. Burstall and Popplestone, U Edinburgh, Forerunner of POP.
U Cambridge and U London. Provides the.. Strongly typed but has a general type enabling a weak form of polymorphism. Functions may be defined as either normal or applicative order. Typed array and polymorphic list structures. List selection is through structure matching. Partially implemented on the Titan Atlas 2 computer at Cambridge.
Led to the much simpler BCPL. Barron et al, Computer J Jul Conversational Programming System. These individuals are often malicious and have many means at their disposal for breaking into a system. The term was coined ca. An earlier attempt to establish worm in this sense around on Usenet was largely a failure. This box cranks or, cranks at about 6 megaflops, with a burst mode of twice that on vectorised operations. I just wasted 30 minutes downloading this stinkin' crapplet!
The non-TeX enthusiasts generally dislike it because it is more verbose than other formatters e. A sudden, usually drastic failure. Most often said of the system, especially of magnetic disk drives the term originally described what happened when the air gap of a hard disk collapses. Three lusers lost their files in last night's disk crash.

A crayola might also be a killer micro. Someone who works on Cray supercomputers. More specifically, it implies a programmer, probably of the CDC ilk, probably male, and almost certainly wearing a tie irrespective of gender.
mattirearas.tk Systems types who have a Unix background tend not to be described as crayons. In fact, experience has shown repeatedly that good designs arise only from evolutionary, exploratory interaction between one or at most a small handful of exceptionally able designers and an active user population - and that the first try at a big new idea is always wrong. Unfortunately, because these truths don't fit the planning models beloved of management, they are generally ignored. Software that has some important functionality deliberately removed, so as to entice potential users to pay for a working version.
It generalised Lisp's two-part cons nodes to n-part nodes. Under Unix influence this usage has become less common because Unix uses just line feed as its line terminator. An awkward feature or programming technique that ought to be made cleaner. For example, using small integers to represent error codes without the program interpreting them to the user as in, for example, Unix make1, which returns code for a process that dies due to segfault.
A common example of crosstalk is where the magnetic field from changing current flow in one wire induces current in another wire running parallel to the other, as in a transformer. Crosstalk can be reduced by using shielded cables and increasing the distance between conductors. The absence or failure of any one of these is often a sign of a bad design or poor testing.
Also used as a verb, as in cruft together, hand cruft. Connotes an essentially trivial operation that is nonetheless painful to perform.
The pain may be due to the triviality's being embedded in a loop from 1 to 1,,, Fortran programs do mostly number crunching. One who hacks or implements software or hardware for cryptography. A system for encrypting and decrypting data is a cryptosystem.
