SK0-003 · Question #749
A technician is replacing memory in a server whose motherboard supports PC2100 memory. This type of memory is also known as which of the following?
The correct answer is B. DDR. PC2100 memory refers to a specific type of DDR (Double Data Rate) SDRAM, indicating a peak transfer rate of approximately 2100 MB/s. It is the first generation of DDR memory, preceding DDR2 and DDR3.

Why each option
PC2100 memory refers to a specific type of DDR (Double Data Rate) SDRAM, indicating a peak transfer rate of approximately 2100 MB/s. It is the first generation of DDR memory, preceding DDR2 and DDR3.
DDR2 memory modules are identified by the 'PC2-' prefix, such as PC2-3200 or PC2-6400, not PC2100.
PC2100 memory is a designation for DDR-266 SDRAM, which operates at a bus speed of 133 MHz and a data rate of 266 MT/s, providing a theoretical bandwidth of 2.1 GB/s (approximately 2100 MB/s). DDR, or DDR1, was the initial iteration of Double Data Rate memory that transfers data on both the rising and falling edges of the clock signal.
SDRAM is a broad category of synchronous dynamic RAM, and while DDR is a type of SDRAM, PC2100 specifically denotes the first generation of Double Data Rate SDRAM, not generic SDRAM.
DDR3 memory modules are identified by the 'PC3-' prefix, such as PC3-8500 or PC3-10600, not PC2100.
