What does IP stand for?

• A. Internet Protocol
• B. Internal Process
• C. Interface Protocol
• D. Internet Provider

Answer: (A)

IP stands for Internet Protocol. This is the set of rules that governs how data is addressed and routed across networks. Each device gets an IP address, like a mailing address, so routers can forward packets toward their destination. IP operates at the network layer and uses routing to move packets through multiple networks; it’s a best-effort system, meaning it doesn’t guarantee delivery—that’s handled by higher-layer protocols like TCP. IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses to expand the address space.

The other terms aren’t used to name the protocol responsible for addressing and routing. An Internet Provider is a service you subscribe to, not the protocol itself, and the other two phrases aren’t standard names for this foundational networking concept.
