What is the wrong statement about the difference between memory and hard disk?

The answer is – b.

Alas, that's right. Memory and hard disk are both storage devices, but memory works by means that data does not reside, overflow replaces.

B, is wrong. 16g inner pure and hard disk that is big?

c, that's right. Even SSDs can't compare to memory at the moment.

D, that's right. This answer is in the reverberation audio-visual, after the power is off, the information in the memory and the hard disk are retained, the memory is not empty after the power is off, but when the computer is restarted, the data in the memory is changed, the speed of reading and writing data in the memory is very fast, but even if it is fast, the information is also saved in the memory.

To give a simple example, the Windows system, whether it is XP, or Win7, will have a process of sorting out data when it is illegally shut down and restarted, in fact, this process is to write some data in memory to the hard disk, so, D's statement is correct.

d is wrong. The memory is RAM, and no data is saved when the power is off.

If it is not multiple choice, the answer is definitely D.

The statement b is only a general statement, but generally speaking, the capacity of hard drives is larger than that of memory. You don't have to stick to these words. No one is going to make a 1g hard disk.

Some people can't even figure out what memory is, and they still answer blindly. The memory is called ramramdom

access

memory) is a type of random read-write memory. Constant charging and discharging is required to save data. The profession is called pre-charge.

Search the Internet to find out. For example, if the system goes to sleep, the memory must be powered. At this time, the memory cannot be plugged and unplugged.

Because there is data stored in it. If you power it off, it won't be able to remember the data.

Of course, choose D, the memory uses capacitor access, and it needs to be constantly refreshed to keep the data, except for the memory power supply when entering S3 (sleep), and the memory will be powered off when it is shut down and hibernated, and the capacitor cannot keep the data after the memory is powered off.

The hard disk uses disk access, and the data does not disappear when the power is off.

Answer]: B hard disk is characterized by large storage capacity and fast access speed. The hard drive can be formatted, and after formatting, the data on the hard drive is lost.

Each computer can be equipped with more than one hard disk to expand the storage capacity. The CPU can only access the hard drive by accessing the information that the hard drive stores in memory. After a power failure, the data stored in the hard drive will not be lost.

The following statement about hard disks incorrectly touches ().

a.The data in the hard drive will not be lost after a power failure.

b.Each computer owner has and can only have one hard drive.

c.The hard disk can be formatted.

It is not possible to directly access and upgrade the data in the hard drive.

Correct answer: B

d, the information in the memory is definitely gone, similar to what you have in the clipboard, and it must be gone after restarting. Also, if you change to the current SSD, or flash in the tablet, you are not in the right question. It can be seen that it is also the exam question in middle school.

d. Memory information is not retained after power failure.

Individuals choose a memory (memory), and I also hold Kirimori is called Duan Mu for internal memory.

It is used to temporarily store the computing wheel scrambling data in the CPU, as well as external memory such as the hard disk.

Data exchanged.

CPUs include combinators and controllers.
