ZEEBO: A device funded in great part by chipmaker Qualcomm (creator of the CDMA technology for cell phones) that downloads video games over fast 3G cell phone networks.  Introduced only in emerging markets so far.

ZERO DAY EXPLOIT: A virus, malware or intrusion that takes advantage of a security vulnerability in an operating system or program on the same day that the vulnerability becomes known. It is particularly dangerous because it occurs before anti-virus and anti-malware programs are aware of it and have had the opportunity to develop a solution and make it available for download to users.  See, Exploit, SPYWARE.

Zigbee logoZIGBEE: A low cost, low power, secure wireless mesh IP networking communication protocol using small low-power digital radios to connect to cell phones via short-range radio.  It boasts longer battery life, longer range and higher reliability than Bluetooth or other WPAN protocols.  Used for wireless light switches, electrical meters with in-home displays and other consumer home automation and industrial remote control equipment that require stable RF (“radio frequency”) capabilities.  See FAQ #80 for more about how it used with home automation.  Along with Z-Wave, these are the two most common applications used for this purpose.  The name Zigbee is said to refer to the “waggle dance” of honey bees upon their return to the bee hive.  For military and some higher-end commercial uses, Zigbee has recently been eclipsed by Dash7.

ZIMLET: A feature of the open source Zimbrzimbra_logoa enterprise e-mail system for Macs and Linux servers which allows users to interact with other outside applications.  For example, if you mouse-over a date or time, you will see what’s in your calendar, mouse-over a flight and you can see if it’s on time, mouse-over an address and you can see a map.  Sometimes, however, it can cause trouble:  If the “I Want Thissoftware is installed on your computer, it can corrupt Comcast Xfinity with a search error that prevents you from using your browser (cure it by setting your IE settings back to default). Where does the name Zimbra come from?  The developers claim that they got it from the Talking Heads musical group, where the tune “I, Zimbra” can be found on the Fear of Music collection.  Talking Heads was interested in Dadaism, which can be defined as “a protect against an intellectual rigidity in both art and everyday society.”

ZIP: (1) A file that has been compressed (i.e. “zipped”) using a popular program named PKZip.  Other popular programs include WINRAR, SecureZip and WinZip.  Macs use Stuffit(2) Also the name of a high density (100 - 750Mb) Superfloppy drive and disk, manufactured by Iomega (see Media).

ZOMBIE: A computer attached to the Internet that has been compromised by a hacker, computer virus, trojan horse or the like so that it can be used to remotely perform malicious attacks.  Because the users of the infected computers are generally unaware that they are being controlled remotely, they are metaphorically compared to Zombies.  Zombies are generally part of botnets, which are groups of zombies, remotely controlled to achieve their means, such as DDOS attacks on web servers. The word has a long history way before computers, originating  as far back as 1932 in the film “White Zombis,” starring Bela Lugosi.  For more, see, SPYWARE.

ZONE FILE: A  text file, each line of which describes a “resource record” that resides on the domain host or name server for a website.  The zone file designates a domain, the subdomains and e-mail servers and maps them to IP addresses and other resources.

Mark Zuckerberg photoZUCKERBERG, MARK: Nickname:  “Zuck”.  For those of you who haven’t seen the movie, the founder of Facebook.

ZUCKERBERG’S LAW: That each year, Internet users will share twice as much information as they share this year, and twice as much information as they did the year before.  Therefore, he postulates, that people are using Facebook, and its applications and the ecosystem, more and more.  This “law” was stated by Zuckerberg at the Web 2.0 Summit on September 15, 2011.

Zune

ZUNE: Microsoft’s contender against Apple’s iPod as a portable music player.  Both a hardware player and a software download site.  In October, 2011, the hardware was discontinued by Microsoft, but the software app remains active.

Z-WAVE: A wireless communications standard designed primarily for home automation, used in virtually all household remote controls.  Because it operates apart from the 2.4Ghz frequency of 802.11 wireless systems, it is impervious to interference from common household or computer wireless systems.

ZYNGA: A social network game developer from San Francisco, which develops browser-bZynga logoased games (CityVille, FarmVille) that work both stand-alone (on mobile phones) or on social networking sites such as Facebook and MySpace.  It was founded in July 2007 by Mark Pincus and was named after his American Bulldog.  It is considered the #1 Facebook app developer with over 40 million MAU.  But after a great year in 2011, 2012 proved to be a disaster, so bad that many business publications have predicted its demise.
