Checking the software version number is an important step when troubleshooting problems, updating programs or installing plug-ins. Common methods are as follows: 1. Windows system can be viewed through the software "About" page, "Details" or "Settings>Applications>Installed Apps" in the software's "About" page, shortcut properties; 2. Mac and iOS devices can be found in the About page, Settings>General>About>About>About>About>Applications in the software menu bar, and some apps also indicate the version on the App Store details page; 3. Browser extensions can be viewed through chrome://extensions/ (Chrome) or add-on page (Firefox), and web service can identify the version number through the resource URL in the Network tag of the developer tool. Different platforms and software types correspond to different operation paths, so pay attention to the details.
Checking the software version number is actually a very simple but often overlooked operation, especially when troubleshooting problems, updating programs, or installing plug-ins. Here are some common and practical methods.

How to check the software version on Windows system
Most software on Windows can view version numbers through the "About" page or the property bar. for example:

- After opening the software, click Help > About in the menu, and a pop-up window will usually display the current version number.
- Right-click the desktop shortcut → Properties → Details tab page, you can see the file version and product version
- If it is an application with your own system, you can open "Settings>Applications>Installed Applications" and find the corresponding software to view details
Sometimes you will find that the two version numbers are inconsistent, which may be because one is an internal build number and the other is an external release number, which depends on the main purpose.
The viewing method is slightly different on Mac and iOS
The way to view the software version on Mac and iPhone is relatively uniform, but there are some details that need to be paid attention to:

- Open any Mac software, click the software name next to the Apple icon in the upper left corner, and select the About software to see the version number
- On iPhone or iPad, go to Settings > General > About this machine > Applications , find the target app to view the version
- Some third-party software also provides version information in the Settings or My pages
Note that some apps will also indicate the latest version number in the App Store details page to facilitate your comparison of whether you need to update.
How to view the version of browser extensions and web services
Browser plug-ins and web-based tools also have version numbers, but the viewing method is different:
- Chrome extensions can be entered in the address bar to find the corresponding plug
chrome://extensions/
- Firefox users can also view it in the add-on page
- For web-based tools (such as Google Docs, Trello, etc.), the version number is not displayed directly, but you can use "Developer Tools> Network" to see if the URL of the loading resource contains version parameters.
Although this type of version number is not as intuitive as local software, it often comes in handy when feedbacking bugs or contacting customer service.
Basically, just choose the appropriate method according to different platforms and software types. The operation is not complicated, but it is easy to ignore the details. In particular, some software hides the version number more deeply and can be found by clicking a few more menus.

The core of artificial intelligence is algorithms, especially models that can learn laws from data, such as deep learning. It trains the system through a large amount of data, allowing it to make judgments on new situations, such as face recognition and chatbots. AI is not really intelligent, but statistical methods that mimic human behavior. Common applications include voice recognition (such as Siri), image recognition (such as Alipay face-scanning payment), recommendation systems (such as TikTok and Taobao recommendations), and autonomous driving. AI's capabilities have boundaries, it can only work within the scope of training data, has no real awareness, and relies on a large number of computing resources. When looking at AI, it should be rational. It is an efficient tool but not perfect. It can be used to improve efficiency, but it also needs to be wary of its limitations.
