Motherboard
CPU (Central Processing Unit, Processor)
Network Interface Card
CPU Socket
Where CPU plugs into motherboard
PSU (Power Supply)
Provides power to computer
 Big plug connects to motherboard
 Smaller plus connect to components
Reduces voltage
RAM (Random Access Memory)
HDD (Hard Drive – Magnetic/Spindle)
 Stores data bits by changing magnetic polarity.
SSD (Solid State Drive)
 No moving parts
 Stores data bits by trapping charge in
capacitor.
Hard Drive vs SSD Identification
GPU (Graphics Processing Unit)
Mini HDMI
DVI (obsolete)
Integrated Components
Component built onto motherboard:
 GPU / video
 Sound
 USB hub
Bus (Omnibus)
Circuits built into motherboard
Connects groups of peripherals
Connects Northbridge and Southbridge
Busses (Omnibusses)
Multiple busses on the motherboard
Connect groups of components
Can be serial or parallel
Connect parts that operate at different speeds
Important busses:
◦
◦
◦
◦
Front Side Bus
Northbridge
Southbridge
PCI
Northbridge
Connects faster components:
 Memory
 CPU
 PCI-e graphics
Controls communication
 Tells process and RAM when to read, write
Now often integrated into CPU!
Southbridge (Obsolete as of 2011)
Connects slower components:




PCI
USB
SATA
BIOS
Replaced by PCH
People still say “Southbridge”
Ports, Plugs & Connectors
PLUG OR CONNECTOR
PORT OR SOCKET
The part that fits into the plug
The part that the plug fits into
Usually on the cable
Usually on the device
AKA the "male" end
AKA the "female" end
PCI (Peripheral Component Interface)
•Connects to Southbridge
•Old and slow now
•Parallel connection
•Used for cheap components:
• Sound cards, USB expansion
•Only one size
PCI-Express
•Connects directly to Northbridge
•High Speed
•Serial connection
•Commonly used for GPUs or Storage Devices
•Different Lengths:
• 1x
• 8x
• 16x
USB (Universal Serial Bus)
Used to connect peripheral devices—almost
anything.
Connects to Southbridge
USB - A
Most common USB connection
USB-B
Connects peripherals
Snug connection
Used for big, old devices
USB-C
SATA (Serial Advanced Tech. Attachment)
Little red cables that connect hard drives
Also connects SSD, CD/DVD
Serial
Faster than USB
Most USB hard drives have a SATA connector
inside.v
HDMI (High Definition Media Interface)
Connects to TVs and monitors
One cable can handle:
 HD Video
 HD Audio
 Remote control
 Network
 Getting replaced by DisplayPort
Mini DisplayPort
Connects to TVs and monitors
One cable can handle:






HD Video
HD Audio
Remote control
USB
Network
Competes with HDMI
(2008)
VGA (Video Graphics Adapter)
Old style video connector
Usually blue
Video only
Analog
SoC (System On A Chip)
Motherboard Chipset
iPad Retina SoC
