What is Information?

• Facts and ideas that are expressed through a
  mutually understandable language.
• Has always been around even in the days of the
  caveman.
• No specific way in dealing with information.

How IT helps us?

• Create and keep track of documents
• Control production in factories
• Design new products
• Market products around the world

8
Categories of IT

• Input Technologies-keyboard, mouse
• Communication technologies-h/p
• Processing Technologies-cpu
• Storage Technologies-h/disk, floppy, thumb drive
• Output Technologies-printer, monitor

9
Input Technologies

• Devices that help us gather information from the
  environment and translate that information in a
  form that can be understand by a computer.
• Also known as sensing Technologies.

10
Communication Technologies

• Technologies that tie together and communicate
  information between input, analyzing and output
  technologies.
• Example
• LAN
• Cellular Telephones
• Fax

11
Processing Technologies

• Computer hardware and software.
• Also known as analyzing Technologies.
• Computers take in information from sensing and
  communicating devices and then store and process
  the information.

12
Storage Technologies

• Refers to devices that are used to store data and
  instruction.
• Example
• Hard disk
• Floppy disk
• Optical disk

13
Output Technologies

• Computer hardware and software that make
  processed data available to human users, either
  through sight or sound.
• Also known as display Technologies.
• Example
• Printer
• Monitor
