26 Cards in this Set

  • Front

What two methods can a system use to detect the type of memory installed?
Parallel Presence Detect (PPD) or Serial Detect (SPD).
Name a chip set feature on the system board that checks the integrity of data stored on DIMMs and can correct single-bit errors in a byte.
ECC - Error checking and correction
Which memory detection scheme uses resistors to communicate the type of memory installed?
Parallel Presence Detect (PPD).
What happens to data in RAM when the PC is turned off?
All data in RAM is lost when the PC is turned off.
What is the data path size for Direct Rambus DRAM?
16 Bits.
what is "Conventional Memory"?
The memory adresses between 0 and 640K.

Also called BASE memory.
How many pins are there on the edge connector of a DIMM?
DIMMS have 168 pins on the edge connector.
RAM is divided into what two categories?
Static RAM (SRAM) and Dynamic RAM (DRAM)
What is the Upper Memory Block?
A group of consecutive memory addresses in RAM from 640K up to 1024K that can be used by device drivers and TSR's
True or False:

Expansion cards can have RAM and ROM on them.
True
How many pins are there on the edge connector of a SIMM?
Older SIMMS use 30 pins, newer SIMMS use 72 pins on the edge connector.
What is another name for DDR SDRAM?
SDRAM II
What is the data path size of a DIMM?
The data path size of a DIMM is 64 bits.
What is Asyncronous SRAM?
Static RAM that does not work in step with the CPU clock.

Slower than syncronous SRAM.
The assigning of addresses to RAM and ROM during boot up is called what?
Memory Mapping.
Computer memory is divided into what two categories?
RAM and ROM
True or False:

A system board can support both syncronous and asyncronous SRAM, but not at the same time.
TRUE
What is a BUFFER?
A temporary memory area where data is stored before being written to a printer or disk drive.
What is the data path size for a SIMM?
A SIMM has a data path of 32 bits.
what is the memory above the initial one Megabyte called?
Extended memory
Why is it called "Dynamic" RAM?
Because it constantly needs refreshing.
What is a BANK?
An area on the motherboard that contains slots for memory modules. Typically labeled bank 0,1,2 and 3.
What kind of memory can hold data even when the power is turned off?
Flash memory
What type of ROM can be erased using UV light?
EPROM
What is DDR SDRAM?
Double Data Rate syncronous dynamic ram - A type of memory used on DIMMS that runs at twice the speed of the system clock.
What is an EEPROM?
Electrically erasable programmable ROM.
