Cloud Computing: Benefits and Limitations

Play an AI-generated podcast conversation about this lesson

What is a fundamental requirement for cloud computing, and what are the consequences if it is not available?

A constant Internet connection is required for cloud computing. If it is not available, no work can be done and access to applications and documents is impossible.

How do low-speed internet connections affect the performance of cloud computing?

Low-speed internet connections, such as dial-up services, make cloud computing painful and often impossible, as web-based applications require a lot of bandwidth to download.

What is a limitation of web-based applications in cloud computing compared to desktop-based applications?

Many web-based applications are not as full-featured as their desktop-based applications, limiting their functionality.

How does cloud computing affect device independence, and what are its implications?

Cloud computing allows for device independence, as applications and documents are available on any portable device with an internet connection, but it requires constant internet connectivity. Signup and view all the answers
