The following key indicators that affect hard disk performance are correct.

• A.The hard disk data transfer rate refers to the speed at which the hard disk reads and writes data, and the unit is knots per second (MB/S)
• B.The factors affecting the capacity of the hard disk are the capacity of a single disc and the number of discs
• C.Applications with frequent random reads and writes, such as OLTP services. IOPS is a key measurement indicator. Another important indicator is data throughput, which refers to the amount of data that can be successfully transferred per unit time
• D.The average access time of the mechanical hard disk refers to the average addressing time of the disk

The frequency of the CPU includes the main amount, the outer cheeks, the total frequency and the frequency multiplier. The statement about frequency multiplication under D is wrong.

• A.Under the same external frequency, the higher the frequency multiplier is, the higher the thing is, without restrictions
• B.The frequency doubling system refers to the relative proportion between the main CPU item and Waiton
• C.R Guo Zuo is right to adjust the signal frequency of the CFU without indignation. The super state that adjusts the frequency multiplier is quite stable.
• D.The speed of data transmission between the CPU and the system is limited, and the CPU that blindly pursues high principle and obtains high frequency multiplication will have a bottleneck effect of the net legs.
