引导唯一性在不同的机器上 [英] Guid Uniqueness On different machine

问题描述

可能重复:
GUID是否在100％的时间内是唯一的?

Possible Duplicate:
Is a GUID unique 100% of the time?

在阅读有关Guid的所有帖子后，我仍然不清楚一件事:

After reading all posts on Guid, still I am unclear about one simple thing:

由不同机器生成的向导也保持其唯一性.

Guids generated by different machines also maintain their Uniqueness or not.

我已经了解了单台计算机上的GUID唯一性，但是我仍然不知道不同机器上的GUID唯一性

I have read about guid uniqueness on single machine,but I still don't know about uniqueness with different machines

推荐答案

GUID实际上是 普遍 唯一.

GUID are "practically" universally unique.

GUID是128位整数(16个字节)，可在需要唯一标识符的所有计算机和网络中使用.这样的标识符被复制的可能性非常低.

A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated.
