logic. Use the print command to display all usable tags. For example, (parted) set 1 boot on sets the boot tag of the partition numbered 1 to the on (effective) unit (set unit) format: unit: Select a unit that indicates the disk size for Parted. After that, all the numbers about the disk location (such as the start position of the partition) use this unit, and you don't need to give the unit suffix. (For example, if you select MB as the unit, 512 represents 512 MB, and you don't need to add mor

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 the Code code as follows: function Countdirsi

Byte: bytes are units that transmit information over the network (or store information in hard disks or in memory).Bytes are a unit of measurement used by computer information technology to measure storage capacity and transmission capacity, with 1 bytes equal to 8-bit binary.In ASCII, an English letter (not case) occupies a single byte of space, and a Chinese character occupies two bytes of space.Symbol: English punctuation occupies one byte, Chinese punctuation is two bytes. Example: "." 1 byt

Computer storage unit bit (BIT) (binary digits): stores a bit of binary, that is, 0 or 1, the smallest storage unit. Byte: eight binary bits are one byte (B), the most common unit. That is, 1B (byte bytes) = 8 bit computer storage units are generally represented by B, kb, MB, GB, TB, Pb, EB, ZB, Yb, BB, the relationship between them is: 1 kb (kilobyte kilobytes) = 1024b, 1 MB (megabyte megabytes referred to as "megabytes") = 1024kb, 1 GB (

Run-Time System and Virtual Machine A run-time system consists of an execution engine, a machine-level debugger, A assembler, and related development tools). Standard Operation Procedure (SOP): declares a proposition for demonstration and provides examples. That is, proposition-proof-example. This topic is suitable for System Engineers. Virtual machines must meet the following three criteria:1) portabilityPortability is the most important feature. It allows applications to work on consis

of binary numbers, which is generally an 8-bit binary number as a numerical unit in a computer. For example, an ascii code is a byte. The conversion of such units is:1 gib (TB, terabyte) = 1024 gib (40 to the power of 2)(1 TB = 1024 GB)1 gib (GB, gigabyte) = 1024 MB (2 to the power of 30 bytes)(1 GB = 1024 MB)1 MB (megabyte) = 1024 kilobytes (20 to the power of 2)(1 MB = 1024kb)1024 bytes (kb, kilobyte) =
