2. 1. INPUT HARDWARE
consists of devices that
take data and programs
that people read or
comprehend and convert
them to a form the
computer can process.

3. 2 types of Input Hardware
 KEYBOARD ENTRY
 DIRECT ENTRY

4. Text Input Devices
 KEYBOARD
TERMINAL

5. Pointing Devices
MOUSE
TRACKBALL
TOUCH SCREENS
LIGHT PENS
DIGITIZING TABLETS
PEN-BASED SYSTEMS

6. Game Controllers
STEERING WHEEL
JOYSTICK
GAMEPAD OR JOYPAD
PADDLE

7. Imaging and Video Input
Devices
 IMAGE SCANNERS
 WEBCAM
 FINGERPRINT READER
 BARCODE READER
 3D SCANNER
 SMART CARDS AND OPTICAL CARDS
 VOICE RECOGNITION DEVICES

8. Audio-input devices
• MICROPHONE
• MID-KEYBOARD

9. • SENSORS
• HUMANBIOLOGY
INPUT DEVICES

10. 2. OUTPUT HARDWARE

devices that translate
information processed
by the computer into a
form humans can
understand.

11. Permanent (HARDCOPY)

REFERS TO THE
PRINTED OUTPUT
EXAMPLES:
 Printers (dot-matrix, inkjet, laser, thermal)
 Plotters

12. Temporary (SOFTCOPY)
 refers to data that is known on a display screen or is
in audio or voice form.
EXAMPLES:
• cathode ray tubes (CRT)
• flat-panel display
• Plasma display devices
• Multimedia projectors
• Audio-output
• Video output

13. Action
Consists of processing of a data
that initiate some form of action or
process control activity
Examples:
 CAD/CAM
 ROBOTICS SYSTEM

14. 3. PROCESSING HARDWARE
 Central Processing Unit (CPU)
- follows the instructions of the software to
manipulate data into information
 Control Unit- tells the rest of the computer
system carry out a program’s instructions.
 Arithmetic/Logic Unit- performs arithmetic
operations and logical operations and controls
the speed of those operations.

15. Types of Computer Memory
RAM-known as memory, primary
storage, internal memory, volatile,
temporary storage.
ROM- non-volatile; a permanent software
called firmware, is installed during
manufacturing.

16. Computer use the 2 state, 0/1.
2 binary coding schemes are:
ASCII- American Standard Code for Information
Interchange
- most widely used for microcomputers.
EBODIC- Extended Binary-coded Decimal
Interchange Code
-commonly used in mainframes

17. 4. STORAGE HARDWARE
Storage capacity of computers
is expressed in bits, bytes,
kilobytes, megabytes,
gigabytes, terabytes,
petabytes, or exabytes.

18. Bit-short/binary digit
Byte- 8 bits
Kilobyte- 1,024 Bytes
Megabyte- 1,024 KB
Gigabyte- 1,024 MB
Terabyte- 1,024 GB,
Petabyte- 1,024 TB
Exabyte- 1,024 PB

19. Primary Storage- PAM
Secondary Storage- is any storage devices
designed to retain data and instructions in a
relatively permanent form.
 Tape Storage
 Diskette Storage
 Hard Disks- rigid metal platters that hcid data
as magnetized spots.
 Floptical Disks- a cartridge disk that relies on
a combination of magnetic and optical
technology.

20. Optical Disks
 CD-ROM
 CD-R
 CD-RW
 DVD-R
 DVD-RW
 WORM disks
 BLU-RAY
 LIGHTSCRIBE

21. 5. Communication hardware
 Facilitate the connections between computers
between groups of connected computers
(networks).
 Modulator-demodulator- convert a computer’s
digital signals and vice-versa.
 Fax-modern – a modern with a fax capability
 LAN card- the connection to the internet using
broadband selection.
 Wireless Network Interface Card- used for
wireless connection to LAN card Internet.

22. 6. OTHERS
 Peripheral – a piece of
computer hardware that is
attached to a host computer
expand its capabilities.
 Computer Port- serves as an
interfere between the computer
and other computers or
peripheral devices.

23.  Parallel- a type or interface found on
computers for connecting various
peripherals
 Serial- a serial communication
physical interface through information
transfers in or out 1 bit at time.
 PS/2-used for connecting some
keyboards and mice to a PC
compatible computer system.

24.  IEEE 1394- a serial bus interface standard
FOR HIGH-SPEED COMMUNICATIONS and
isochronous real-time data transfer, frequently
used in a personal computer and digital audio
and digital video devices.
 Universal Serial Bus- a serial bus standard
interface devices to a host computer designed
to allow the peripherals to be connected.
 Ethernet- port used to connect a computer to a
wired network.
