Overview of Information Technology

There are four basic types rather than Information Technology, namely:
1. Sensing
2. Communication
3. Analyzing
4. Display
relating to the functions of input, process, output in an Information System

Input devices (Sensing)
collect or retrieve incoming data from the environment (either directly or by human intervention) and translates into a form that can be processed by the CPU.

Output devices (display)
show / mendisplaykan of data have been processed in a form that can be understood and used by humans.

How to develop Sensing technology? Involved the creation of new tools enter, process multimedia data (eg voice to match, looking for the face of crimes, etc.), as well as recognition / processing of biometric data

Analyzing how to develop the technology? Include the creation of computer architecture and processing tools better

How to develop communications technology? Include the creation of tools for computer communications, as well as the accompanying applications, eg applications for on-line transactions, krs on-line, Management Information Systems, etc.

How to develop display technologies? Include the creation of display devices, etc.
