1. What are the four types of switches?
Single-pole single-throw (SPST) - The most basic switch, with only one input and one output, can be turned on or off.
Single-pole double-throw (SPDT) - There is a common terminal, a normally closed terminal, and a normally open terminal, which can be used to select one of two different paths.
Double-pole single-throw (DPST) - There are two independent single-pole single-throw switches, which operate in conjunction and can control two lines at the same time.
Double Pole Double Throw (DPDT) - There are two independent sets of single pole double throw switches, each with its own common, normally closed and normally open terminals, which can control two lines at the same time, and each line has two state selections. -
2. What is the difference between power switches and signal switches?
The difference between power switches and signal switches is mainly the energy level they handle. Power switches are designed to carry larger currents and powers, and are usually used to directly control power supplies; while signal switches handle smaller currents and are mainly used to control logic levels or routing of small signals.

3. What are multiplexers used for?
A multiplexer is a device that can select one of multiple input signals and direct it to a single output. In digital systems, multiplexers allow data streams to share the same channel, saving space and cost.

4. Is a decoder a transmitter or a receiver?
A decoder is neither a transmitter nor a receiver, but is located between the two to process received data or prepare data to be sent.
