3. INFORMATION PROCESSING
SYSTEM

4. Information Processing System
 DATA is a collection of independent and u
norganized facts.
 INFORMATION is the processed and orga
nized data presented in a meaningful form.
 DATA PROCESSING is the course of doin
g things in a sequence of steps.

5. Information Processing System
 COMPUTER is an electronic machine that
follows a set of instructions in order that it
may be able to accept and gather data an
d transform these into information.

6. PROCESSING S
YSTEM
DATA INFORMATION

7. Functions of an Information Proces
sing System
1. It accepts and gather data. (INPUT)
2. It processes data to become information.
(PROCESSING)
3. It stores data and information. (STORE)
4. It presents information. (OUTPUT)

8. Three Major Components of an Info
rmation Processing System
 HARDWARE is the tangible part of a comp
uter system.
 SOFTWARE is the non-tangible part that t
ells the computer how to do its job.
 PEOPLEWARE refer to people who use a
nd operate the computer system, write co
mputer programs, and analyze and design
the information system.

9. Basic Units of Measurement
 BIT is a unit of information equivalent to th
e result of a choice between only 2 possibl
e alternatives in the binary number system
.
 BYTE is a sequence of 8 bits (enough to r
epresent one character of alphanumeric d
ata) processed as a single unit for informat
ion.

10. Basic Units of Measurement
 A byte can be used to represent a single c
haracter, which can be:
A letter
A number
A special character or symbol, or
A space

12. Basic Units of Measurement
 1,000 bytes =1 kilobyte (K or KB)
1,000 KB =1 megabyte (MB)
1,000 MB =1 gigabyte (GB)
1,000 GB =1 Terabyte (TB)

13. BASIC PC HARDWARE
 HARDWARE is the tangible part of a comp
uter system.

15. Basic hardware of a PC system
 Central Processing Unit (CPU)
 Memory Unit
 Input Devices
 Output Devices
 Secondary Storage Devices

16. 1. Central Processing Unit
 Brain of the computer.
 It directs and controls the entire computer
system and performs all arithmetic and log
ical operations.

17. 2. Memory Unit
 Where the programs and dat
a are stored .
READ ONLY MEMORY (RO
M) contains the pre-program
med computer instructions su
ch as the Basic Input Output
System (BIOS).
RANDOM ACCESS MEMOR
Y (RAM) is used to store the p
rograms and data that you will
run. Exists only when there is
power.

19. 3. Input Devices
 Allows data and programs to be sent to th
e CPU.
Keyboard
Mouse
Joystick
Microphone
Webcam
Scanner
Monitor

20. Keyboard
 Traditional keyboards
 Flexible keyboards
 Ergonomic keyboards
 Wireless keyboards
 PDA keyboards

21. Two Types of Mouse
 Mechanical - a type of co
mputer mouse that has a ru
bber or metal ball on its un
derside and it can roll in ev
ery direction.
 Optical: This type uses a l
aser for detecting the mous
e's movement.

22. How a Mouse Hooks Up to a PC
 PS/2 Mouse
 Serial Mouse
 USB/Cordless Mouse

23. Other Pointing Devices
 Trackball
 Track point
 Touch pad
 Touch Screen

24.  Joystick – input device for
computer games
 Light Pens – light-sensitiv
e penlike device
 Stylus – penlike device co
mmonly used with tablet
PCs and PDAs.

25. Scanning Devices
 Optical scanners
 Card readers
 Bar code readers
 Character and mark recognition devices

26. Image Capturing Devices
 Digital Cameras
 Digital Video Cameras

27. 4. Output Devices
 Media used by the computer in displaying i
ts responses to our requests and instructio
ns.
 Monitor
 Audio Speakers
 Printer

28. Types of Monitor
 Cathode Ray Tube (CRT)
 Liquid Crystal Display (LCD)

29. Printers
 IMPACT PRINTERS uses pressure by phy
sically striking the paper. Ex. Daisy wheel
printers, line printers, dot matrix printers &
band printers.
 NON-IMPACT PRINTER does not apply pr
essure on the paper but instead produces
character by using lasers, ink spray, photo
graphy or heat.

31. Conclusion
Computer hardware is the collection of
physical components that constitute a
computer hardware is the physical parts
or components of a computer.Such as a
monitor, keyboard, computerdata
storage,grafic card, sound card,
motherboard and so on.
