I want to make a circuit that can turn on and off led from two different switches. One can only turn on and the other only off. How do I do it. Thanks.

You can use two separate transistor with two separate switches

Two different transistor can be used to separately turn on and turn off the led using switches.

Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter.
Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information-processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed electronic components into a regular working system, called an electronic system; examples are computers or control systems. An electronic system may be a component of another engineered system or a standalone device.
