Latest Technical buzzwords and Terms

This Thread is all about the latest technical terms which are the buzzwords or are on Trend.......Being Techical guys, it's gud to be familiar with these terms.... Contributions from all of you are invited.

so starting with, some few terms are:-

Google Chromecast:- A small WiFi-enabled dongle device that connects to a television via a HDMI port to wirelessly stream video and music content to the TV screen from smartphone (both Android and Apple iOS), tablet, laptop or #-Link-Snipped-# devices. Google Chromecast made its debut in late July, 2013, and retails for $35, which is considerably less expensive than the $99 Apple TV that Chromecast competes against.

Slack Space:- The term slack space refers to the storage area of a hard drive from the end of a stored file to the end of the file cluster in the hard drive. In typical hard drives, the computer stores files on the drive in clusters of a certain file size. For example, the file system on the hard drive may store files in clusters of four kilobytes. If the computer stores a file that is only two kilobytes into a four kilobyte cluster there will be two thousand kilobytes of slack space. Slack space is a very important form of evidence in the field of forensic investigation. Often, slack space can contain important information about a suspect that a prosecutor can use in a trial. For example, if someone tried to delete files that filled an entire cluster on a hard drive and then saved new files on that cluster that only filled half of the cluster, the latter half of the cluster would not necessarily be empty but might contain leftover information from the first file delete.
