The answer is C: Both of the two students are correct.
Voltage in very simple terms is what makes electric charges move. It is that push or force that causes charges to move in an electrical conductor. Thus, student A is correct since voltage is a specific measure of potential energy that exists and is always relative between two points. On the other hand, power is the rate, per unit time, at which electrical energy travels. Electrical power (P) is the product of both voltage and current and not either one separately. It is a function of voltage and current. Thus, student B is also correct.
The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
Answer: a. RADIUS
Explanation:
RADIUS as developed with the idea of allowing its users or clients to be able to authenticate to a dial-in access server. So basically it is a client server protocol and he client here is the firebox and the server is the RADIUS server.
The authentication mechanism start by user who sends a message to the RADIUS server. Then the RADIUS server upon receiving the message accept or denies it. It accepts if the client is configured to the server.
A large amount of additional information can be sent by the RADIUS server in its Access-Accept messages with users so we can say that RADIUS is uitable for what are called "high-volume service control applications" such as dial-in access to a corporate network.
