What is a Web Service? And why is it called a Web Service?

Web services are a simple way of how applications can use the Web. They are a way to use Web technologies for providing an Application Programming Interface (API). That's different from what a Web page is for, which is a User Interface (UI) that is intended to be used by a human user. Web services open a whole new world of opportunities because now any application can take advantage of Web technologies, and not just Web browsers.
This video explains how the Web is based on the foundation of the Hypertext Transfer Protocol (HTTP) and why this matters for Web services and Web pages. Web pages use HTTP to retrieve Web pages using the Hypertext Markup Language (HTML) which is then displayed in the browser. Web services use HTTP to exchange raw data with the JavaScript Object Notation (JSON) being the most popular data format.

Why is this video so criminally underrated? I really like the fact that he included the part about history of web services. Knowing why some technology came into existence and what problem it is solving is very important. It's like a veil was lifted. Thank you so much bro

I looked this up through multiple channels and forms, and in some cases was more confused than when I initially started.

Erik, you did a fantastic job of breaking this down into laymen terms and presenting it with a concise, yet informative structure. Thank you sir! I am now a subscriber....
