The correct answer is: C. http
The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.
HTTP is a stateless protocol, which means that each request from a client to a server is independent of any previous requests. This makes it possible for multiple clients to access the same server simultaneously without interfering with each other.
HTTP is a request-response protocol, which means that the client initiates the communication by sending a request to the server. The server then responds to the request by sending a response back to the client.
HTTP is a text-based protocol, which means that all communication between the client and the server is in the form of text. This makes it easy to debug and troubleshoot HTTP problems.
HTTP is a simple protocol, which makes it easy to implement and understand. This makes it a popular choice for a wide variety of applications, including web browsing, file transfer, and email.
The other options are incorrect because:
- SMTP is the Simple Mail Transfer Protocol, which is used for sending email.
- OCCI is the Open Cloud Computing Interface, which is an API for managing cloud resources.
