Question 3

Accepted Answer

No, because you use a network to connect to the internet

Question 4

What is the difference between a protocol and an algorithm?

Accepted Answer

A protocol is a standardized set of rules that determine how data is transmitted between different devices in the same network.

You can think of a protocol as being analogous to a natural language. In this discussion, we are both communicating using English, and since we are both adhering to the rules of the English language (syntactical, grammatical, etc.), we can understand each other.

An algorithm on the other hand is a finite series of steps that solve a problem. For example, if I want to solve the problem of sorting, then I can use Quicksort (https://en.wikipedia.org/wiki/Quicksort) - or any of the myriad of other sorting algorithms - to solve that problem. Quicksort boils down to a series of well-defined steps that can be written as code and then executed by the computer to perform sorting.

 it's waves or signal. When our internet get stop. Why it's happening?

Accepted Answer

The portion of the electromagnetic spectrum over which wireless communication occurs (i.e. radio spectrum) is far below the visible light spectrum, making it impossible to see the signals used by the Internet.

There are numerous reasons that your Internet might stop working. It's a complex system and failure of any of the parts could keep it from working correctly. Anything from weak signals to misconfigured firewalls, failed DNS queries, or corrupted packets could cause issues.
