Rollover
Rollover means closing out a position in the current-month futures contract and taking a fresh position on the next-month futures contracts.
Script
In computer programming, a script is a program or sequence of instructions that is interpreted or carried out by another program rather than by the computer processor (as a compiled program is).
Scripting
A scripting language is a form of programming language that is usually interpreted rather than compiled. Conventional programs are converted permanently into executable files before they are run. In contrast, programs in scripting language are interpreted one command at a time. Scripting languages are often written to facilitate enhanced features of Web sites. These features are processed on the server but the script in a specific page runs on the user's browser.
Security
In the computer industry, refers to techniques for ensuring that data stored in a computer cannot be read or compromised by any individuals without authorization. Most security measures involve data encryption and passwords. Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. A password is a secret word or phrase that gives a user access to a particular program or system.
Sharpen
All digital photographs lose a certain amount of sharpness. That means that most photographs will look a bit blurred and their details won’t be as prominent. Basically, sharpening makes the edges of a photographed object appear more distinct.
Serif:
In typography, serifs are semi-structural details on the ends of some of the strokes that make up letters and symbols. A typeface that has serifs is called a serif typeface (or seriffed typeface). A typeface without serifs is called sans-serif, from the French sans, meaning “without”. Some typography sources refer to sans-serif typefaces as "grotesque" (in German "grotesk") or "Gothic," and serif types as "Roman."
Sans Serif:
In typography, a sans-serif or sans serif typeface is one that does not have the small features called "serifs" at the end of strokes. The term comes from the French word sans, meaning "without".
In print, sans-serif fonts are more typically used for headlines than for body text.[1] The conventional wisdom holds that serifs help guide the eye along the lines in large blocks of text. Sans-serifs, however, have acquired considerable acceptance for body text in Europe.
Sans-serif fonts have become the de facto standard for body text on-screen, especially online. This is partly because interlaced displays may show twittering on the fine details of the horizontal serifs. Additionally, the resolution of digital displays in general can make fine details like serifs disappear or appear too large.
Before the term “sans-serif” became standard in English typography, a number of other terms had been used. One of these outmoded terms for sans serif was gothic, which is still used in East Asian typography and sometimes seen in font names like Century Gothic. Sans-serif fonts are
sometimes, especially in older documents, used as a device for emphasis, due to their typically blacker type color.
Shockwave
A technology developed by Macromedia, Inc. that enables Web pages to include multimedia objects. To create a shockwave object, you use Macromedia's multimedia authoring tool called Director, and then compress the object with a program called Afterburner. You then insert a reference to the "shocked" file in your Web page. To see a Shockwave object, you need the Shockwave plug-in, a program that integrates seamlessly with your Web browser. The plug-in is freely available from Macromedia's Web site as either a Netscape Navigator plug-in or an ActiveX control.
Shockwave supports audio, animation, video and even processes user actions such as mouse clicks. It runs on all Windows platforms as well as the Macintosh.
A site map
(or sitemap) is a list of pages of a web site accessible to crawlers or users. It can be either a document in any form used as a planning tool for web design, or a web page that lists the pages on a web site, typically organized in hierarchical fashion. This helps visitors and search engine bots find pages on the site.
While some developers argue that site index is a more appropriately used term to relay page function, web visitors are used to seeing each term and generally associate both as one and the same. However, a site index is often used to mean an A-Z index that provides access to particular content, while a site map provides a general top-down view of the overall site contents.
Smart quotes
To make these typesetting characters easier to enter, publishing software often converts typewriter apostrophes to typographic apostrophes during text entry (with or without the user being aware of it). This is known as the “smart quotes” feature. Apostrophes and quotation marks that are not automatically altered by computer programs are known as “dumb quotes.” Some implementations incorrectly enter an opening single quotation mark in places where an apostrophe is required, for example, in abbreviated years like ’08 for 2008.
