Why is information 
technology 
important?
It's been said that data is what powers 
industries worldwide. That may be hyperbole, 
but few businesses  large or small can remain 
competitive without the ability to collect data

Without information technology, online 
purchases would be impossible, and it would 
be impossible for banks to keep these

Healthcare
 Improvements in information technology 
have allowed for great reform in healthcare. 
Most medical offices can now send and 
receive digital medical information from 
doctors you've had in the past. 
Changes like this allow costs to be lowered 
and increase the amount of time doctors can 
spend on patients compared to paperwork.

 Security
With so many transactions done online and so 
much information available online, its 
important to keep all of that safe. Information 
technology makes it possible for your online 
data to stay secure until accessed by the 
proper channels. 
Using passwords and encryption, information 
technology hides your personal digital data 
away, and the only way it can be accessed is 
by companies who have permission from you.
