Will help you understand future technologies
Information Technology A field of study focused on managing and processing information
and the automatic retrieval of information. Includes; computers, telecommunication and software
- The fastest growing career industry is computers
- Data Mining The process of searching huge amounts of data with hope of finding a
pattern and used to separate anomalies from the trends. For example large retailers often
study the data gathered from register terminals to determine which products are selling on
a given day and in a specific location.
- UPS tracks packages with tracking systems. The company creates a smart label for the
package. The smart label contains a MaxiCode. The maxicode is a specially designed
scannable sticker that resembles an inkblot and contains all the important info about the
package. When package is handed in UPS scans MaxiCode using handheld devices.
- These handheld devices use Bluetooth technology (type of wireless communication) to
transmit the scanned data through radio waves to a terminal.
- Art and dance is also using computers to a further level. For example computer that
