What is the purpose of HTTP in web communications?

• A. To resolve domain names
• B. To route packets
• C. To standardize language for requesting and receiving web resources
• D. To transfer emails

Answer: (C)

HTTP defines a common language for web communication. It specifies how a client (like a browser) asks for a resource and how a server returns it, using a consistent structure of requests and responses with methods (such as GET and POST), headers, and bodies, along with status codes that describe the result. This standardization lets different browsers and servers talk to each other and reliably fetch web resources across the internet. Other options refer to DNS for resolving domain names, the network layer for routing packets, and email protocols for transferring messages, none of which are the purpose of HTTP.
