Day 3 Check Chat and Real-time Communication

Check yourself

Ten questions on the two designs from Day 3, WhatsApp and Discord. Both are chat, both hold long lived connections, and both persist before delivering. What separates them is that one delivers to a person and the other broadcasts to a room, and almost every difference follows from that.

You will be asked 10 questions drawn from a larger bank, so a second attempt will not be the same paper. Answer from what the designs actually said, not from what sounds sensible in general.
