will the quality increase after the U disk or hard disk is filled with materials?
to answer this question, let's take a look at the storage principles of the USB flash disk and hard disk.
a USB flash drive, also known as flash memory, uses flash as the storage medium. In short, flash uses a float gate to store data. A float gate is a charge trap that can store charges. The process of writing data to flash is the process of injecting charge into this charge trap.
As for hard disks, SSD is widely used, and most of the storage media is dram, in simple terms, DRAM uses a capacitor to access data. The capacitor can charge and discharge, and can store data. When there is a charge, it is "1", and when there is no charge, it is "0 ".
back to the problem at the beginning, the above analysis shows that before and after a USB flash disk or hard disk is filled with data, what changes is the digital signal record content, that is, a lot more electrons.
the Electronic quality is about 9.20.38188e-31 kg, quality will increase, but the increase is very small.
Similarly, we can think about how many pieces of data each bit has?
As we all know, computers use a string of binary "1" and "0" to represent all kinds of information-email, documents, videos, webpages, everything.
Taking the memory of a general computer for example, the storage mechanism is the dram just mentioned. After charging the capacitor, it indicates "1". If it is not charged, it indicates "0 ". The data of bit "0" is electronic, that is, there is no quality, while the data of bit "1" is quality, although it is negligible.
The memory capacitor needs to be considered. The estimated value is that each capacitor can be filled with only 40 thousand electrons, and the quality of 40 thousand electrons is 3.6e-26 kg. That is to say, the data quality of BITs "1" is 3.6e-26 kg.
Finally, let's calculate the total weight of global Internet information!
To get this result, we need the total amount of information flowing on the Internet. We can find the answer from the book "Internet Development 2006" by cleford huolidi: the total traffic is ...... The surprising 40 P byte, that is, 4 bytes-4 followed by 16 0.
Not all bits are "1", or the network content is too boring. On average, about half of the bits are "1" and the other half are "0 ", that is, the 20 p bit "1", apply the formula of the computed bit "1" Data weight, and get the total number of 7.2e-9 kg.
After having written so many guilty words, we finally come to the conclusion that the total weight of the Internet is about one thousandth of one ounce (about 28 grams per ounce.
