WGU C393: Chapter 1 - Motherboard, Processors, and Memory, VERIFIED. RATED A+ Power supply exhaust fan - -A fan found at the back of the power supply used to cool the power supply A fan that draws air from inside the case into vents in the power supply and then blown out of the case TPM (Trusted Platform Module) - -Dedicated security coprocessor or crypto processor Allows BIOS to boot the system only after authenticating the boot device UEFI (Unified Extensible Firmware Interface) - -Successor for BIOS Allows secure boot and support for higher storage amounts L2 (Level 2) - -A type of cache on the motherboard, external to processor Cache speed: 256k L3 (Level 3) - -A type of L2 cache present in processor's package but not on die Cache Speed: 4MB-12MB DIMM (Dual inline memory module) - -64-bit memory modules that are used to package the SDRAM family; A type of memory package that differentiates the functionality of the pins on one side of the module from the corresponding pins on the other side PROM (programmable ROM) - -A type of memory that can be written to one time in the field using a special programming device Example: CD-R EPROM (erasable PROM) - -A type of memory that can be erased using ultraviolet light and subsequently reprogrammed Example: CD-RW EEPROM (electronically erasable PROM) - -A type of memory that can be erased using an electrical pulse and subsequently reprogrammed Example: Flash drive LGA (Land Grid Array) - -A type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket (when a socket is used) rather than the integrated circuit. Lid over CPU with L-shaped arm to lock in place DRAM (Dynamic Random Access Memory) - -A cheaper less complex type of memory used to expand the memory in a computer Memory Access Time: 40ns SRAM (static random access memory) - -A more complex and expensive but fast type of memory Memory Access Time: faster than 10ns DDR3 SDRAM (double data rate, version 3, SDRAM) - -A type of memory designed to be twice as fast as DDR2; Memory Peak Voltage: 1.5v DDR2 SDRAM (double data rate, version 2, SDRAM) - -A type of memory that splits each clock pulse in two, doubling the number of operations you can perform per FSB clock cycle Memory Peak Voltage: 1.8v DDR SDRAM (double data rate SDRAM) - -A type of memory that transfers a bit per pin on both the rising and falling edges of the clock signal Memory Peak Voltage: 2.5v Sealing - -Authentication that confirms the hardware being booted has been tied to the system containing the BIOS and TP
