|Samples Per Inch||
Samples Per Inch (SPI) indicates the number of data points per inch that a scanner captures (i.e. input). As opposed to Dots Per Inch, Pixels Per Inch, or Lines Per Inch - all of which refer to output. Although most scanner manufacturers refer to Dots Per Inch, they really should refer to Samples Per Inch. Scanners use Charged Couple Devices ( CCDs) to capture information, and they do this by taking a fixed number of samples per inch. The thing to watch out for in scanners is optical resolution vs interpolated resolution. If a flatbed scanner is making claims of higher than 600 DPI, you can be pretty sure that they're referring to interpolation. Interpolation increases the resolution by software. The highest resolution a scanner can capture without interpolation is the optical resolution.
|Search Engine Optimization||
Search Engine Optimization is a division of the larger Search Engine Marketing world. Unlike the internet marketing methods that involve paying for listings on search engines, search engine optimization is a strategy that aims at increasing the website's performance on the search engines in organic, or natural, means.
Short for search engine results page, the web page that a search engine returns with the results of its search. The major search engines typically display three kinds of listings on their SERPs. Listings that have been indexed by the search engine’s spider, listings that have been indexed into the search engine’s directory by a human, and listings that are paid to be listed by the search engine.
Software that acts as an online store's catalog and ordering process. Typically, a shopping cart is the interface between a company's website and its deeper infrastructure, allowing consumers to select merchandise; review what they have selected; make necessary modifications or additions; and purchase the merchandise.
Social media is the online technologies and practices that people use to share opinions, insights, experiences and perspectives with each other. Think of it as online communities in which people share. They may share experinces, preferences or websites they like. Examples of social media websites are: Twitter, Digg, Facebook, MySpace, Reddit, Squidoo, LinkedIn and YouTube.
A web crawler also known as a "robot" which is an automatic software program that serves a search engine by exploring the Web and collects Web page addresses and stores them in a huge database.
