What is the bus speed of PC-100 SDRAM?

100MHz
133MHz
200MHz
266MHz

The correct answer is: 100MHz

The bus speed of PC-100 SDRAM is 100MHz. This is because PC-100 refers to the standard for synchronous dynamic random access memory (SDRAM) with a maximum data transfer rate of 100 megabytes per second (MBps). The other options of 133MHz, 200MHz, and 266MHz refer to PC-133, PC-200, and PC-266 SDRAM respectively, which all have higher data transfer rates. Therefore, they are incorrect options for the bus speed of PC-100 SDRAM.
