VRAM
- Virtual RAM
- hard drive space used to deliver information to RAM faster
-
cache memory
- very fast form of memory forged from static RAM
- predicts what the CPU wants next and pre-fetches it
- only the most recent info
- external cache or Level 2 (L2) cache
-
Socket
flat with several rows of holes arranged in a square
-
PAC
- Pin Array Cartridge

Header connection
- allows you to mount the ports to the computer's case
- on the backpane
- uses a special cable called a header
-
Header
male connector that terminates the motherboard's traces for that function
-
Direct-sodder method
- mostly used in integrated motherboards
- no cables
- port is part of the mb
- ports can be disabled in BIOS setup
-
BIOS Chip
- Basic Input/Output System chip
- contains software
- tells processor how to interact with the rest of the hardware in the computer
-
CMOS chip
- Complimentary Metal Oxide Semiconductor chip
- parameter memory for the BIOS
- saves date, time, hard drive config, and memory when computer is unplugged
- powered by watch-sized battery
-
Jumpers and DIP Switches
used to configure various hardware options on the mb
