As we are seeing it with the name 'Wall'. It is basically a type of wall and to cross this wall there is only one gate and security guard are available at the gate. Every time when you want enter inside/outside  the wall you have to go for the security check. This is the main concept of firewall in internet networks.

Now we will take an example to understand clearly, what is firewall and what is the use of firewall and why it is necessary for every internet user.

Let's take an example of a home or office, we know that everyone does not know what's happening inside your home or office except you. Like in office there are some important works happening and no one outside of the office know about that work. There can be some important files and if someone enters in that room then what will happen.

Your answer will be, important files of the office may be theft or insecure. And it can also lead to loss of office.

Working of Firewall:

Now to keep your office fully safe from unknown people or thief, you will arrange a watchman at the gate of your office, whose job is to keep a strong watch on people who come in and out of office and if you get a little inking then you will not allow them in and out. You will not let you go out of it, meaning that the security should be very tight, if this happens then how much fun will it be?
