The sticks of RAM snapped into your motherboard
are known as ______ RAM
|
DRAM
|
|
Think of DRAM as a spreadsheet in
which each cell holds either: ______
|
A one or a zero
|
|
Each cell represents a single: _____
|
Bit
|
|
The number of columns and rows on RAM are: _____
|
Finite
|
|
If a chip contains 1,048,576 rows and 8 columns,
it can be described as a ________ .
|
1 M × 8 chip
|
|
A chip containing 2,097,152 rows and 16 columns can be described as a ________ .
|
2 M × 16 chip
|
|
DRAM needs to be able to fill the _1_.
A 1 M × 8 DRAM chip is only _2_ wide and would
provide the CPU with only _3_ of data.
|
1) data bus
2) 8 bits
3) 8 bits
|
|
You would need __1__ of the __2__ to fill a 64-bit data bus.
|
1) eight2) 1 M × 8 chips
|
|
DRAM chips are soldered to a_1_called
a stick or module, and when these chips are
combined, a single stick can fill the_ 2_.
|
1) circuit board
2) data bus
|
|
Modern DRAM sticks come in ___ bit and ___bit wide varieties.
|
32-bit- and 64-bit
|
|
Synchronous dynamic random access memory, or
SDRAM, is tied to the _______.
|
System clock
|
|
The _1_, _2_, and _3_ all work in tandem with the clock pulse. This results in little wasted time when the _4_requests data from RAM.
|
1) CPU
2) Memory controller
3) RAM
4) CPU
|
|
SDRAM comes in sticks called ____ ____ ____ ____
|
dual inline memory modules (DIMMs)
|
|
SDRAM DIMMs come in a variety of pin sizes, with __ pins being the most common for desktop systems.
|
168
|
|
DIMMs are 64 bits wide so that they match the
|
64-bit data bus of modern CPUs.
