The protocol CGI is . . . . . . . .

Solution (By Examveda Team)

This question asks about the CGI protocol, which is used in web development.

Let's break down the options:

* Option A: computer graphics interface: This refers to how computers interact with graphics, and it's not related to web development.
* Option B: common graphics interface: This is not a standard term in web development.
* Option C: computer gateway interface: This is a close guess, but it's not the correct answer.
* Option D: common gateway interface: This is the correct answer. CGI stands for Common Gateway Interface.

In simple terms, CGI allows websites to interact with programs or scripts (like those written in Python or PHP) to generate dynamic content. This means the website can do more than just display static pages.

For example, CGI could be used to:
* Process form submissions (like a contact form).
* Fetch data from a database and display it on a web page.
* Create personalized content based on user preferences.

So, the answer to the question is Option D: common gateway interface.
