Software version number
Software that you often use is generally from the version number, of course, does not exclude a small number of disposable no version numbers. What is the meaning of version number? From the version number we can get a lot of information.
Generally speaking, the version number is: 1.45, generally pure numbers. 1 indicates the primary version number, which generally said that the version of greater than 0 can provide very perfect function. The second one is the secondary version number, indicating that some function expansion and improvement is provided on the basis of the current main version. However, there is no thorough improving all the features, the third bit 5 generally means that the current version is revised, which is released on the 1.4 version of the version of the bug version.
The software version is divided into α / β / λ, in general α is the version number of the software development company's internal test. For example, Longhorn now flows should be an internal version. At this time, the version is still a certain distance from the final version, and it is not full of functions. The beta version is more than that, it is the public beta, and when the beta version is released, the official version of the distance is not far away. I will not add any new features any more. Basically, what is the official version is what it is. The λ version is official version, but there are very few such calls.
Based on business considerations, many software is not very rigorous to follow this rule. The most famous is Microsoft. For example, his NT series. Everyone is more familiar to start from NT 4.0. In 1999, Windows 2000 was launched in 2001, with Windows XP. In 2003, Windows 2003 was launched. At first glance, it is quite big, but it will find that the internal version number will find that the change is not big, it is only interface changes. Great. This is what software is often doing. The version number of Window 2000 is NT 5.0. The version number of Windows XP is NT 5.1, and the version number of Windows 2003 is NT 5.2, and the current Longhorn is the real NT 6.0 (the impression is not confirmed). This will continue to earn money for the majority of customers. After all, people 's eyes are most intuitive, so I feel that it is also the biggest change.
Based on the above reasons, it can be seen that the current software developers are more based on the business purposes, maybe the pure technical era has been away from us.
