5. Chapter 1: Sharing

6. Chap 1: Motherboard Form Factors
“Form factor” affects
Shape and size of motherboard
Shape and size of case
Screw holes in the case
Type of power supply
Most common: ATX.
Second place: MicroATX

7. Chap 1: Hard Drives

8. Chap 2: Working Inside a Computer
IMPORTANT SAFETY TIPS
Always power down and unplug a computer before working on it.
Handle boards and cards by the edges.
Never open a power supply or a monitor.

9. Chap 2: Working Inside a Computer
Just a matter of removing screws to access the inside.
Use a ground bracelet.
Remove cards by lifting straight up ( i.e. not by rocking them side to side)

25. Chap 3: CPU Manufacturers
Intel – Generally pricier but better performance.
AMD – Generally cheaper but worse performance.
This changes a lot. In the 90s, AMD seemed to be leading the way while Intel lagged behind.

26. Chap 3: Main Intel Chipsets
1. Northbridge-Southbridge: NB handles fast tasks (PCI-E and RAM to CPU), SB handles slow stuff ( PCI Bus, Keyboard and Mouse, etc.)
2. Nehelem : Northbridge functions moved onto CPU.
3. Sandy Bridge and beyond: Northbridge and graphics controller functions moved onto CPU.

27. Chap 3: Buses

28. Chap 3: Configuring a Motherboard
The BIOS is the first thing that runs when a computer is turned on.
It initializes, tests, and/or configures hardware components.
Access the BIOS by pressing a special key during boot. Usually it is F2, F10, Del or Esc.

29. Chap 3: More about BIOS BIOS can be password protected.
Settings are saved in a CMOS chip that is given constant power by a battery.
Updating the BIOS with a new version is called “Flashing the BIOS”. This can be dangerous because if something goes wrong and the BIOS is damaged, the system might never boot again.

30. Chap 3: Group Activity Building your own PC
1. What motherboard form factor and why?
2. What type of socket and why? Which processor?
3. What type of expansion slots (PCI, AGP, etc.) and why? What will you put in them?
4. What wattage/type of power supply and why?
5. How much RAM and hard drive space? What case?
5. How much will it cost?

31. Chap 4: Processors Mainly manufactured by Intel and AMD
Important features of Processors:
Processor Speed (900MHz, 3.2 GHz)
Multiprocessing Capabilities
HyperThreading (Intel) and HyperTransport
Multiple Cores on one chip
Socket and Chipset (PGA 988, AM3+)
Architecture (32-bit or 64-bit)

32. Chap 4: More Processor Features
Memory Cache (L1,L2,L3)
Supported Memory Features (DDR2,DDR3)
Virtualization Support (must be enabled in BIOS)
Integrated Graphics (Ivy/Sandy Bridge)
