GUID (Global unique identifier) is a globally unique identifier, which consists of the ID numbers on the NIC (each Nic has a unique ID number) and a 16-byte binary value generated by the unique number of the CPU clock. The GUID format is "xxxxxxxx-xxxx-xxxxxxxxxxxx", where each x is a hexadecimal number in the range of 0-9 or a-f. Example: 76895313-839E-4E89-BAFC-B253BFF3173F No two computers in the world will generate duplicate GUID values. GUID is used to assign a unique identifier to a netw

1.UUID can be used when a unique ID is required in the system.It has several different versions and implementations; The simplest way to obtain UUID in Linux is to use the command: uuidgen. It has two options:-R and-T. The former is based on random number (random), and the latter is based on time ). If you wantProgramUUID can be used to call the uuid_generate function.. 2.Random Number Generat

Python iterator and generator use instance, python generator instance I. Iterators The iterator is only a container object and implements the iterator protocol. It has two basic methods: 1) next MethodReturns the next element of the container. 2) _ iter _ MethodReturn iterator itself The iterator can be created using the built-in iter method.

In ubuntu, we found that the system uses UUID to uniquely represent the hard disk partition, for example: #/Dev/sda1# UUID = 45f8-9147/Media/sda1 vfat defaults, utf8, umask = 000 0 1/Dev/sda1/Media/sda1 vfat defaults, utf8, umask = 000 0 1#/Dev/sda5UUID = 5668d81168d7edad/Media/sda6 ntfs-3g ults, NLS = utf8, umask = 000 0 1 One advantage of using/dev/sda5 to directly reference a partition is that when a n
