These are all devices called network connectivity devices. They allow a network to be either extended in range, or to add other clients/devices to the network.
They have different functionality depending on what the client connection is used for.

Network+ Guide to Networks answer: Bridge, Switch, Router
The main difference between a router and a gateway is in their functionality in a network. A router will be connected to two different networks and will transmit packets between them. As for the gateway, it will link different networks using varied protocols.
Bridges, Switches and Routers will all separate collision domains.
Switches and Bridges
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
Two different networks are connected by a router. Switches are used to connect network devices within networks.
the router interface closest to the computer
Switches connect computers directly together while bridges connect switches, router etc together
yes
The "default gateway" is your router.
