Which of the following RAM modules has a PC rating of 10600?

The correct answer is C. DDR3. RAM modules use a PC rating system that corresponds to their generation and speed. The PC rating is calculated as the memory's data transfer rate (in MT/s) multiplied by 8 (the bus width in bytes). DDR3 modules use the 'PC3' prefix. PC3-10600 corresponds to DDR3-1333 (1333 MHz…

Explanation

RAM modules use a PC rating system that corresponds to their generation and speed. The PC rating is calculated as the memory's data transfer rate (in MT/s) multiplied by 8 (the bus width in bytes). DDR3 modules use the 'PC3' prefix. PC3-10600 corresponds to DDR3-1333 (1333 MHz × 8 bytes = 10,664 MB/s, rounded to 10600). By comparison: DDR uses 'PC' ratings (e.g., PC-3200), DDR2 uses 'PC2' ratings (e.g., PC2-6400), and SDRAM uses 'PC' ratings at much lower speeds (e.g., PC-133). A PC rating in the 10600 range is exclusively in the DDR3 range.
