　　3. All files in the USB disk have become .exe format files and cannot be opened normally.

　　4. After the USB disk is plugged into the computer, it will take a long time to be recognized by the win7 system computer.

　　5. When double-clicking the USB disk under win7 system, the USB disk directory cannot be opened, even if it is opened, other disk directories are opened.

How does cloud computing work, and what are the benefits and drawbacks of using it?

  Cloud computing is a model for delivering information technology services over the internet. Instead of having software and hardware installed locally on a user's device, cloud computing allows users to access applications and data through a network of remote servers, usually maintained by a third-party provider . This provider is responsible for managing and maintaining the infrastructure, including servers, storage, databases, and software . Here is a more detailed explanation of how cloud computing works: Remote servers: Cloud computing relies on a network of remote servers that are maintained and managed by a third-party provider . These servers can be physically located anywhere in the world. Internet connectivity: To access cloud computing services, users must have an internet connection. This connection allows them to remotely access the resources on the remote servers. Virtualization: Cloud providers use virtualization technology to create multiple virtual machines ...
