A rudimentary error checking scheme that offers no error correction is know as what?
Parity checking
___ is required for the computer system to electrically recognized that the computer minimum number of memory component has been installed.
Bank Memory
___ transfer exactly 64 bits of information at a time.
Standard memory controller
__ manages to memory in chunks of the same size as system bus’s data width.
Standard Memory
Memory controller that support dual-and triple -channel memory implementation were developed in an effort alleviate the bottleneck between the ___ and ___.
RAM and CPU
Briefly explain the terms single -sided memory and double sided memory.
The two refers to how some memory modules have chips oN one side while others have chips on both sides.
list any 3 types of memory.
DRAMA, EDO DRAMA and FPN DRAMA
What is the meaning of this memory DRAM?
Dynamic Random Access Memory.
____ Is characterized by by its independence from the CPU’S external clock.
ADRAM
How was the name DDR was earn?
Double Data Rate earned it name by doubling the transfer rate of ordinary SDRAM;
T/F. ROM can be define as Read Over Memory?
FALSE
Explain the why Read Only Memory is called read only?
Because the orginal form of this memory could not be written to.
The system ROM in the original IBM PC contained _____?
Power on self test (POST), BIOS and Cassette Basic.
The _ enables the computer to “pull itself up by it boot straps “or boot .
System ROM
What is SRAM??
Static radon access memory.
T/F. SRAM does require a refresh signal
False
___ is also called refresh signal
DRAM
____ supports memory based on the speed of the front side bus (or the CPU’S QPI) and the memory’s form factor.
Motherboard
___ is classically used for cache memory?
Static Random Memory
___ access time come in at 40 nanosecond.
DRAM
__ is more complex, thus more expensive and access times faster 10 ns?
SRAM
___ is a memory type that was designed to be twice as fast as ___ memory that operates with the same system clock speed.
DDR3 and DDR2
Why wait states is inserted in DRAM through the Bios setup for faster CPU to enable the same memory as a slower CPU?
Because ADRAM is not sychronized to the frontside bus, u would often have to
__ was the term used to refer to the only form of sychronous DRAM on the market
SDRAM
Why you used DRAM to expand memory?
Because it’s the cheaper type of memory
