Explanation:
All the listed services — Twitter, Skype, and Gmail — are built on cloud-computing technology. Here's how:
- Twitter: Uses cloud infrastructure to scale, store tweets, and manage millions of concurrent users.
- Skype: Operates over the internet using cloud servers for voice/video calls and messaging.
- Gmail: A Google service entirely cloud-based, offering email access from anywhere via web and mobile apps.
These services rely on cloud computing for scalability, availability, storage, and performance.
Explanation:
HTTP is stateless, meaning it does not maintain session information between requests. Each request is independent .
HTTP follows a request–response model, where the client initiates a request and the server responds. That means communication is always client → server → client, not simultaneous in both directions.
Although newer versions (like HTTP/1.1 with pipelining or HTTP/2 multiplexing) allow more efficient handling, HTTP is still fundamentally half-duplex—it’s not full duplex because only one side can actively send at a time.
Why not the other options?
(A) Stateful – Incorrect. HTTP doesn’t preserve state between requests .
(C) Bidirectional – Incorrect. While data does go back and forth, it's not spontaneous from both ends; the server only responds after a request.
(D) Full duplex– Incorrect. Only one side transmits at a time; true full duplex (simultaneous two-way communication) is seen in protocols like WebSocket, not HTTP.
So, HTTP is best described as a stateless, unidirectional (half-duplex) request–response protocol.
Answer: (B) unidirectional
