Q

You have a computer with the Pentium IV CPU and two PC – 2400 DDR modules. The motherboard has room for two additional memory modules, and you would like to install two PC – 4000 modules. Which of the following statements is true?

–All memory will operate at 300 MHz

– You cannot mix memory modules with different ratings

– Half a memorable operate 300 MHz and other half at 500 MHz

– All memory will operate at 500 MHz

A

All memory will operate 300 MHz

(all memory will operate at the slowest speed)

17
Q

Which of the following is an error detection technique that can detect errors with only one bit?

– ECC

– EDO

– Non-parity

– Parity

A

Parity

(Parity can only detect erros with one bit while ECC can detect erros with more than one bit)

18
