• Maintain your computer- How to care and maintain your computer

• Make good purchase decisions- determine which computers and devices match your need

• Integrate the latest technology

Be a Savvy Computer User and Consumer


Computers in the Workplace

• Information technology (IT) involves:– Information handling– Information retrieval– Computers– Telecommunications– Software deployment

• The seven fastest-growing occupations are computer related.


Computers in Your Career?

• Computers are used in:– Business– Retail– Delivery– Arts– Computer gaming– Education

–Law enforcement–Legal system–Agriculture–Automotive technology–Medicine–Sciences


Computers in Business, Retail, and Delivery

• Data mining- process of searching amount of data to find a pattern or trends-allows retailers to respond to consumer buying pattern

• Package tracking- using Bluetooth tech(wireless communication through radio wave)

• Forecasting models - assist business with predicting sales and inventory levels


Computers in the Arts• Create Web sites-advertise

to public• Creative arts- been

enhanced by computers-communicate and collaborate across the country

• Digitize dance movements• Produce computer-

generated art


Computers in Gaming• The computer and

video game industry is huge.

• Get a job doing:– Design– Programming– 3D animation
