2. Three usages of computer technology in sports :
- Instant Replay : In NBA, instant replays is used at the end of all four quarters to determine whether or not a shot made at the last second was good or not. The basketball needs to leave a player's hand before the buzzer goes off for the points to count. Computer technology allows referees to watch the play in slow motion and make sure that the ball left the player's hand before the clock reached zero.
- Accuracy : Computer technology allows for increased accuracy in different sporting events. Tennis tournaments have sensors set up along the out-of-bounds and service lines that give off a signal if the ball touches them. If any portion of the tennis ball touches a line, it means the ball is "in". It can be difficult for umpires to make these calls from their vantage point. Swimming events use sensors to determine the winner of each race. Because many races are determined by hundredths of a second, it can be almost impossible to tell who won, even through replay. Sensors are set on the wall of the swimming pool, so that when a swimmer hits the wall, the time is recorded and the correct winner can be awarded.
- Cameras : At every sporting event, advanced computer technology is used in the cameras and broadcast quality of the event. There are multiple cameras set up for every game, match or contest, and in the NFL, networks have cameras set up all over the field to help viewers feel like they are part of the game. These cameras are held up by strings, stay behind the offense and have the capability of moving at any angle to ensure they stay our of the way of the action on the field. All of theses cameras have high definition capabilities, so every detail and nuance of the game can be seen on televisions by fans.
8. Three Online Social Networks / Media Sharing :
- Facebook : Facebook is a social networking service launched in February 2004, owned and operated by Facebook, Inc. As of September 2012, Facebook has over one billion active users, more than half of them using Facebook on a mobile device. Users must register before using the site, after which they may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or "Close Friends".
- Twitter : Twitter is an online social networking service and microblogging service that enables its users to send and read text-based messages of up to 140 characters, known as "tweets". It was created in March 2006 by Jack Dorsey and launched that July. The service rapidly gained worldwide popularity, with over 500 million active users as of 2012, generating over 340 million tweets daily and handling over 1.6 billion search queries per day. Since its launch, Twitter has become one of the top 10 most visited websites on the Internet, and has been described as "the SMS of the Internet." Unregistered users can read tweets, while registered users can post tweets through the website interface, SMS, or a range of apps for mobile devices.
- Google+ : Google+, sometimes abbreviated as G+, is a multilingual social networking and identity service owned and operated by Google Inc. It was launched in June 28, 2011. As of September 2012, it has a total of 400 million registered users of whom 100 million are active on a monthly basis. Unlike other conventional social networks which are generally accessed through a single website, Google has described G+ as a "social layer" consisting of not just a single site, but rather an overarching "layer" which covers many of its online properties.
