Firewall Security And Use In World.

INTRODUCTION :-

Hello friends, how are you all once again I welcome you all to my website Technology Inspire (Firewall & use in every computer).

The topic on which we are going to talk today, what is that fire ball and why is it so important in today’s time? We all take care of one thing before doing any small or big work in our life and that is safety. For example, people save some money in advance for their future so that later they can be used properly if needed.

Parents are always with their children for the safety of their children. Who are big celebrities and ministers. Bodyguards are kept for their safety. Everyday on the border, the soldiers of our country risk their lives to protect the country.

In the same way, some security is needed to keep the computer safe from viruses, malwares and threats from outside, and this security is also called firewall.

In this article, we will learn more about Firewall in more depth. Just keep reading till the end.

WHAT IS FIREWALL ?

Those people who use computers and the Internet a lot, those people must have heard the name of firewall. Don’t worry if you don’t know anything about Firewall.

A firewall is a program designed to protect the computer from all kinds of threats such as hackers, viruses and malware. Firewalls are threats from outside on our computer that try to get inside the computer through the Internet and which secretly come inside our computers and all the personal details are sent to the software, which is passed on to the hacker. Use it very wrong.

Firewall is a type of security scheme that is either in the form of a software program or in the form of a hardware device. Whenever our computer device connects to the Internet, then this firewall prevents the traffic coming towards our computer from coming in.

Example .

Whenever we go to a website using the Internet in a computer , watch a video and also download them or we are working on the Internet other than all these, then whatever traffic When it is coming towards our computer, it is blocked by the firewall.

Firewall stands like a wall around our computer network so that any unwanted software does not come in and install automatically in the computer. Due to which the virus attack on the computer and delete all that data.

WHICH NETWORK FIREWALL ALLOWS IN ?

Firewall allow only those things to enter the network. Those whom we allow i.e. users to come in, apart from this, no unwanted traffic is allowed to come in.

Now a question must be coming in the mind of all of you that if our computer already has virus and when we share any file or data with any other user, will the firewall stop the virus from coming?

So let me tell you that Firewall not only blocks the traffic coming from the internet but also blocks the traffic coming from all sides so that the computer data cannot be stolen. That is why it is important to have a firewall in every computer so that the security remains.

TYPES OF FIREWALL :-

So far we have learned what is firewall and why is it being use so much and now we will know how many types of firewalls are there? So like I told you earlier that there are two types of firewalls.

1. Hardware Firewall .

Nowadays hardware firewalls are already present inside routers, whose job is to prevent viruses from passing from one computer to another. For example, say 10 computers in a room are connected to the same network and the router or modem is being used there. If Firewall has been enabled in it, then all the computers that are connected to that router, the firewall will start working automatically.

Whenever any work is done through the Internet, there firewalls prevent the computer from getting dangerous software like viruses and malwares to our computer.

The request from the computer comes out in the form of a data packet and is associated with a network ID, which lets Firewall know that this data is correct and allows it to enter their computer. Apart from this, if any other data packet tries to enter your computer, then Firewall stops it outside. Due to which our device remains completely safe.

Not only this, if a virus comes from anywhere in one of your computers, then that virus does not leave that computer and reach the other computer. Firewall also takes care of this well.

2. Software Firewall .

The new generation Windows operating systems like Windows 7, 8, 10, Vispa, XP and also the new Windows that have come, Windows 12 , all of them have Firewall already inbuilt.

Moreover, firewalls remain on by default. If you want, you can set it as per your wish.

Anti-viruses

Apart from this, many antivirus are also present in the internet. Like Avast, McAfee, Norton, Quick Heal etc. The work of firewall is the same in all of them.

Whenever we install a new software or game in our computer, a popup box appears in our computer in which Firewall asks permission from the user whether you want to install this program in your computer because Windows Firewall has blocked this program. has been blocked. So if we want, we can also install the program by clicking that option.

Software firewalls work in the same way in computers and keep our personal data safe from hackers. Whether it is a hardware firewall or a software firewall, it is very important to use Firewall in the computer because there are many unwanted websites in the Internet that go into your computer system and steal your personal data or delete that data. Firewalls keep our computers safe from these threats.
