Yes, though really its a lot of servers.

I wouldn't worry about tools yet, I'd recommend getting a book/wiki on networking if you'd like to learn, its knowledge that builds.

Believe me, you aren't going to get used to nor enjoy "browsing" the web with curl. It's not what you think it is.

https://en.wikipedia.org/wiki/Swiss_Army_knife

A swiss army knife is a single tool that contains a number of other smaller tools that you can use in many different circumstances.

Curl is a metaphorical "swiss army knife" for connecting to computers. There are many protocols to connect to different kinds of computers running different kinds of software and curl allows one to easily connect to many of them.

hypertext transfer protocol and hypertext transfer protocol secure. it's the basic network protocol of the modern internet. hypertext can be thought of as being html (hypertext markup language) though other hypertext specifications do exist. hypertext just means documents with links to other documents.

you know how when you copy a url (universal resource location) from your web browser it always has http or https at the start of it? that's because your web browser is connecting to an external server somewhere via the hypertext transfer protocol.

cURL can connext to nearly any server via nearly any standard protocol. it's commonly used for validating connection information and downloading files

It's the protocol most computers use to show websites. In an internet address like https://google.com/, the https:// is the protocol. Different protocols have different features and purposes, but http/https are some of the most common.

Not these days.

Curl isn't just a command line tool, it is also a "library" which other computer software uses. Everyone's phone uses curl under the hood. Almost every electronic device that connects to something remote uses curl under the hood.

I still don't understand what you're trying to do.

Curl is not a terminal emulator. Unless you provide a better reason I am now assuming you are a troll.
