Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Choose the answers that are TRUE.
A
Cache memory is built into various components on a computer, including the processor.
B
Cache memory is cheaper, because it is slower than normal memory (RAM) but it can increase the overall performance of a computer quite dramatically.
C
In general, the higher the speed of the CPU, the slower it will perform.
D
Fragmentation has no affect on speed of SSDs.
Explanation: 

Detailed explanation-1: -The answer is short and simple-do not defrag a solid state drive. At best it won’t do anything, at worst it does nothing for your performance and you will use up write cycles. If you have done it a few times, it isn’t going to cause you much trouble or harm your SSD.

Detailed explanation-2: -It’s worth noting that Solid-State Drives performance is not only affected by the amount of data you store in them, but also performance will vary per manufacturer, components quality, features, and grade level.

Detailed explanation-3: -The reason there’s no point defragmenting an SSD is that there’s no seek time or rotational latency. Instead, SSDs access flash memory (NAND) at much higher speeds, typically less than 50us-that’s 50 microseconds, or compared to a typical hard drive with a 15ms average access time, about 300 times faster.
