What is Curve Tracer ???

Hey guys, I had just received my assignment , and seriously, I need help to understand it :???:

1.) What is Curve Tracer ?
2.) What is Voltage Controlled Current Source ?
3.) What is Device Under Test ( DUT ) ?
4.) What is current sensing resistor ?
5.) How these things work together to become a curve tracer ?

These are my biggest question, I do not know any of them as my lecturer didn't teach us about these so far :sad:
So, is there any link or website that can help me to understand more ? Or, if you have any idea, please share with me :-D
Thanks A lot ~~~

1.

A semiconductor curve tracer is a specialised piece of electronic test equipment used to analyse the characteristics of discrete semiconductor devices such as diodes, transistors, and thyristors. Based on an oscilloscope, the device also contains voltage and current sources that can be used to stimulate the device under test (DUT).

2.

A transconductance amplifier (gm amplifier) puts out a current proportional to its input voltage. In network analysis, the transconductance amplifier is defined as a voltage controlled current source (VCCS) .

3. The term DUT is used generally within electronics to refer to any electronic assembly under test.

4.

Current sense amplifiers (also called current shunt amplifiers) are special purpose amplifiers that output a voltage proportional to the current flowing in a power rail. They utilize a "current-sense resistor" to convert the load current in the power rail to a small voltage, which is then amplified by the current-sense amplifiers. The currents in the power rail can be in the range of 1 A to 20 A, as a result, the current-sense resistor is a very low ohmic value resistor (usually in the range of a 1 mΩ to 100 mΩ).
