How to join these sentences

This article explains:

• What is the website?
• What is the internet?
• What is the email?
• What is the software?

I want to write all above sentences in one sentence, how can I write it?

Please help me?

(Can I say: This article explains what is the website,

This article explains what is the website, internet, email, and software? or What the website, internet, email, and software are?)

Please help me.

Thank you
