This document provides an overview of common computer components, including input devices like keyboards and mice, output components like printers and monitors, processors and their sizes and speeds, different types of memory like ROM, RAM, and flash memory, expansion cards that add capabilities like video, sound, and networking, and storage devices that connect to the motherboard like hard drives using SATA or PATA connections.

2. Input devices
• Keyboard
• Mouse
• Games controller
• Microphone
• Tablet
• Touch screen

3. Output components
• Printer
• Monitor
• Speakers

4. Processors
• A CPU (central processing unit) is considered
the brain of the computer as it remembers
what happens internally.
• Sizes of CPUs; 8-bit, 16-bit, 32-bit, and 64-bit
• Speed of CPUs;

5. Technical Memory
ROM (read only memory)- computer
memory which once data has been
written onto, it cannot be removed and
only read.
RAM (random access memory)-
memory that can be accessed
randomly, it is the most common
type of memory found in most
devices.
Flash memory- a type of EEPROM that
can be easily erased and
reprogrammed. Modern PCs have their
BIOS stored on flash memory chips.

6. Technical Adapter Cards
•Expansion Cards- on a motherboard you can insert
expansion cards to give you added capabilities. For
example:
•Video Adapters- gives display capabilities, depending
on how powerful your adapter card is, you will receive
much more graphic power.
•Sound cards- enables output sounds through
speakers, and sound input from a microphone.
•Internal modems- enables you to insert Ethernet
cables into the computer.

7. Technical Storage Devices
• SATA (serial advanced technology
attachment)- SATA connection, connects hard
drive to the motherboard.
• PATA (Parallel advanced technology
attachment- the original hard drive
technology that uses a parallel data channel
from the motherboard to the disk drives.
