A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it.
What is emits light ?The ability of matter to emit light depends on its state of excitation, which can occur for a number of reasons as we shall demonstrate. Light is often emitted at specific energies by the atoms and molecules that make up matter. Either a spontaneous or induced light emission process can occur.When current passes through a semiconductor device called a light-emitting diode (LED), the LED emits light. The semiconductor's electrons and electron holes interact once more to produce photons, which are energy particles.Fluorophores, which release photons when they transition from a high-energy "excited state" to a low-energy "ground state," are the molecules that are involved in these reactions that give off our glow.To learn more about emits light refer to:

Prior to completing a challenge, insert a COMMENT with the appropriate number.
1) Get an integer from the keyboard, and print all the factors of that number. Example, using the number 24:
Factors of 24 >>> 1 2 3 4 6 8 12 24
2) A "cool number" is a number that has a remainder of 1 when divided by 3, 4, 5, and 6. Get an integer n from the keyboard and write the code to determine how many cool numbers exist from 1 to n. Use concatenation when printing the answer (shown for n of 5000).
There are 84 cool numbers up to 5000
3) Copy your code from the challenge above, then modify it to use a while loop instead of a for loop.
5) A "perfect number" is a number that equals the sum of its divisors (not including the number itself). For example, 6 is a perfect number (its divisors are 1, 2, and 3 >>> 1 + 2 + 3 == 6). Get an integer from the keyboard and write the code to determine if it is a perfect number.

6. Why don't WE need to know exact IP addresses for the devices that we use?
Answer:
We don't need to know the exact IP addresses for the devices that we use because our devices use a network such as the internet to communicate with each other, and the network itself is responsible for routing the data between devices using their IP addresses. When we use our devices to access a network, the network assigns our device a temporary IP address, which is used to identify and communicate with our device within the network. This means that we only need to know the IP address of the network itself, rather than the specific IP addresses of all the devices that we use.
