1. COMPUTER
PERIPHERAL
DEVICE

2. OBJECTIVES:
At the end of this lesson, you are expected to do
the following:
1.Identify the different types of computer peripheral
devices.
2.Classify internal and external peripherals.
3.Describe the functions of the different peripherals
4.Relate the concept and learning to real-life
situation of the learner.

3. LET’S WATCH A SHORT VIDEO…

4. COMPUTER PARTS
• There are many parts
that work together to
make a computer
work.

5. HARDWARE DEFINED
• Digital devices that you can touch:
• Desktop computers
• Laptop computers
• Mobile phones
• Tablets
• E-readers
• Storage devices such as USB drives
• Input devices such as keyboard, mouse, scanners, or stylus
• Output devices such as printers and speakers
• Digital devices process electronic signals in 1’s and 0’s
• The physical parts of a computing device

6. UNDERSTANDING BINARY
• Binary:

7. PC COMPONENTS
Components of a PC:
• Circuit board – also known as the motherboard that holds
the CPU, memory, and storage components
• CPU (central processing unit) – carries out the commands
sent to it by the software and returns results
• Faster is better
• Memory – temporary working area called random-access
memory (RAM)
• Applications are loaded into RAM to run faster
• When computer is powered off, the RAM is cleared
• Bigger is better

8. PC COMPONENTS
• Storage – longer, permanent storage of data
• Bigger and faster is best
• Input/output devices – allows the addition of devices for
input and output purposes via ports on the motherboard or
today by USB
• Keyboard for entering data
• Printer for printing output

9. OTHER COMPUTING DEVICES
• Portable computers
• Smartphones
• Tablets
• Mobile devices such as fitness trackers
• Medical devices such as a pacemaker/defibrillator
• Everyday items – the Internet of Things

Motherboard

11. HARDWARE
• Physical parts of the
computer, including
processor and
memory chips,
input/output devices,
tapes, disks,
modems, cable, etc.

12. CPU
• The Central
Processing Unit

13. PROCESSOR
• The CPU – The chip
or chips that
interpret and execute
program instructions
and manage the
functions of input,
output, and storage
devices.

14. COMPUTER CASE
• Contains the major
components of the
computer. It helps
protect them.
