marketroid
/mar'k*-troyd/ (Or "marketing slime", "marketeer", "marketing droid", "marketdroid") A member of a company's marketing department, especially one who promises users that the next version of a product will have features that are not actually scheduled for inclusion, are extremely difficult to implement, and/or are in violation of the laws of physics; and/or one who describes existing features (and misfeatures) in ebullient, buzzword-laden adspeak. Derogatory. [Jargon File]Last updated: 1995-02-23
Mark I
<computer>
(Or "Automatic Sequence Controlled Calculator", "ASCC") A first generation computer that was designed by Howard Aiken of Harvard University, taking inspiration from Charles Babbage's Analytical Engine. The Mark I, as the Harvard University staff called it, was built by IBM between 1939 to 1944. It was delivered to Harvard University and became operational in March 1944.
The Mark I is considered to be the first full-sized digital computer. It was built from clutches, relays, rotating shafts and switches. It read its instructions from one paper tape and data from another. It could store 72 numbers, each of 23 decimal digits. It weighed about 4500 Kg, had 800 Km of wiring, was used only for numeric calculations, and took three seconds to carry out one multiplication. The IBM archives call it the, "...industry's largest electromechanical calculator." One of the Mark I's first programers was John von Neumann. The Mark I was retired in 1959, and disassembled. Parts are archived at Harvard in the Science Center. It was followed by the Mark II.Last updated: 1996-11-24

Markov chain
(Named after Andrei Markov) A model of sequences of events where the probability of an event occurring depends upon the fact that a preceding event occurred.
A Markov process is governed by a Markov chain. In simulation, the principle of the Markov chain is applied to the selection of samples from a probability density function to be applied to the model. Simscript II.5 uses this approach for some modelling functions. [Better explanation?]Last updated: 1995-02-23
Markov model

Each cell has a bit reserved for marking which is clear initially. During garbage collection all active cells are traced from the root and marked. Then all cells are examined. Unmarked cells are freed.markup
<text>
In computerised document preparation, a method of adding information to the text to indicate the logical components of a document, instructions for layout of the text on the page or other information which can be interpreted by some automatic system.
For example, HTML (Hypertext Markup Language) adds tags to the text to indicate the appearance and behaviour it should have when displayed by a web browser. E.g.:<b>This is bold text.</b> <a href="http://foldoc.org/">This is a link to FOLDOC</a>.Other examples of markup languages are troff, SGML (on which HTML was based) and XML.
