The document discusses the information processing cycle, which consists of four main stages: 1. Input - Entering data into the computer through input devices like keyboards, mice, and scanners. 2. Processing - The CPU processes and interprets the data and programs. 3. Output - The results are presented through output devices like monitors, printers, and projectors. 4. Storage - The information is stored for later use on storage devices like hard drives, CDs/DVDs, or distributed via the internet. The cycle then begins again with new input.

Information Processing Cycle

2. WHAT IS THE INFORMATION PROCESSING CYCLE?
THE SEQUENCE OF EVENTS IN PROCESSING INFORMATION, WHICH INCLUDES
INPUT
PROCESSING
OUTPUT
STORAGE
Input
Storage Process
Output

3. 1. INPUT:-
ENTERING DATA INTO THE COMPUTER IS
CALLED INPUT.
TYPICAL INPUT DEVICES:
KEYBOARD, MICE, FLATBED SCANNERS,
BAR CODE READERS, DIGITAL DATA
TABLETS(FOR GRAPHIC DESIGN), ELECTRONIC
CASH REGISTERS.

4. Performing operations on the data is called processing.
2. Processing
CPU-Central Processing Unit
A central processing unit Or
sometimes simply processor is the component
in a digital computer capable of executing a
program. It interprets computer program
instructions and processes data. CPU
provides the fundamental digital computer
trait of programmability, and are one of the
necessary components found in computers of
any era, along with memory and input/output
facilities. A CPU that is manufactured as a
single integrated circuit is usually known as a
microprocessor.

5. The next step is to get the results
out from the process, and present them in
a useable way. Our brain makes our body
respond by talking, moving OR writing.
Computers need “Peripherals” to do this
ex/ monitor, printer, data projector.
3. Output:-

6. Finally, the information needs to be
sent elsewhere OR stored so it can be used
later. Our brain makes “Memories” of the
information, and we may write it down to look
over later. Computers use “Peripherals” to do
this. Ex/ hard drive, CDs OR DVDs to burn,
Internet.
4. Storage:-

7. And back to Stage 1
Once the information is stored OR distributed, it may be reviewed later by
you OR somebody else. This takes us back to Stage 1 (Input), and the cycle starts
again.
