Answer Details
(a) One difference between star and bus topologies
In a star topology every computer is connected by its own cable to a central device (a hub or switch), so all data passes through that central point; if one cable fails only that one computer is affected. In a bus topology all computers are connected to a single common cable (the backbone), and if that main cable breaks the whole network goes down.

- Hub.
- Switch.
- Router.
- Modem. (Network interface card, bridge and repeater are also acceptable.)
(c) The acronyms in full
- HTML - HyperText Markup Language
- HTTP - HyperText Transfer Protocol
