B. Software Application

This is a supporting application that is on the OS to maximize computer performance. Some application software that is quite popular :

• Microsoft Office
• Photoshop
• Corel Draw
• Auto Card

3. Infoware

This is a documentation of information or data.

4. Firmware

This is a permanent storage medium. Its function is a place to store various data on a computer.

5. Brainware (user)

Brainware is the most important component of information technology. Without the presence of Brainware, our computers will not be able to do it because the computer's function is actually a tool to support user needs.
