terabyte to megabyte

equals 8 bits (1byte=8bit). Eight-bit binary number minimum is 00000000, the maximum is 11111111; usually 1 bytes can be stored in an ASCII code, 2 bytes can hold a Chinese character GB code.3, the wordWhen a computer is processing data, the length of time it accesses, processes, and transmits is called word. A word is usually made up of one or more bytes (usually the integer bits of bytes). For example, the word 286 microcomputer consists of 2 bytes, its word length is 16;486 microcomputer's w

Storage Capacity Unit: Bit, Byte, KB, MB, GB, TB, PB, EB, ZB, YB, zbyb I recently read the Hadoop authoritative guide book, which has been designed by many organizations, However, my previous books seem to only teach GB, The current textbooks may be terabytes or petabytes of data, but I'm not sure. However, in the near future, there may be larger units that can be used, These days I 've been playing a boring game that tests my brain capacity, and I 've learned more about storage capacity uni

, and the maximum value is 255. such as an ASCII code is a byte. UTF-8 encoding: An English character equals one byte, and one Chinese (with traditional) equals three bytes. Unicode encoding: One English equals two bytes, and one Chinese (with traditional) equals two bytes. Symbol: English punctuation occupies one byte, Chinese punctuation is two bytes. Example: "." 1 bytes in size, Chinese period ". "Takes up 2 bytes in size.between different orders of magnitudeData storage is represented in 10

The 5MB of space is missing. It's known that the HDD manufacturers has a different capacity measurement.

The approximate program idea is to use the recursive rules to calculate the amount of space occupied by the directory, and then the value of the space to write into the text file, so long as the access to the TXT file will know how much space occupied, do not have to read the disk frequently, save resources. Each time a user uploads a file or deletes a file, it is re-counted. Of course, you can also save the statistical results in the database. Copy CodeThe code is as follows: function Countdir
