Firewall’s name This computer and the internet world is nothing new. Today Discussion What is the firewall? How does it work? And how much is it necessary for your computer?
What is The Firewall
Friends, what is the firewall? And how does it work? If I tell you these two things, you will know for yourself how much it is necessary for your computer! For example, outside the computer world, the firewall is a type of protection that does not allow the external fire to enter and does not allow the inner fire to go out. This way, the Fire Wall protects you from both sides. If you talk about a firewall in the computer world, it is such protection, whenever you use the internet through your computer and access any website, watch online videos and browse some or send a mail.
Your computer has a virus and your computer is connected to a local network there. And there are more 10-20 computers connected (as it is in your office) So your computer has been infected by viruses, but the firewall works as a protection for computers in your local network.
Friends, the Firewall is usually seen in two types. One is a hardware-based Firewall and another is a software-based Firewall. Let’s now Discussion.
Now how does this router firewall work, whenever you enter an internet website or send a request from your browser to enter, your network ID is included with your sent request? And the router sends the request to the desired server as a packet. And when the return packet from the server reaches the router, that packet also contains your network ID. And the FireWalls in the router can recognize the original packets and send them to your device. Now if a packet comes in a router that takes your network ID, then the firewalls can block it instantly.
Various antivirus makers such as Avast, Norton, AVG, MacAfee etc generally provide firewall protection with their antivirus. Moreover, there is a firewall on the default side of Windows. And software-based Fire Walls also work similarly to hardware-based firewalls. And they have done a lot of work to make you think that you installed a game on your system or computer or installed software and if the game or software is recuperating for an internet connection then you will get a popup from the firewall on your computer.
Until the Internet is granted permission, the software you install will not be able to send or receive any data using the Internet. Windows Fire Wall always monitors that your computer is out of Going Traffic and where inking traffic is their source, their IP address keys, whether they are trusted or incomplete traffic is unwanted software installed. So by all these things, we decide which traffic will come and block any of them.
Many software on your computer comes with antivirus type but the software itself is a type of virus. Sometimes you may enter a site and you get the message “Euro system memory is low” or “your device has been infected with viruses, clean it now” and so on. Whenever you read these messages, when you click them, any software is downloaded to your computer. And this software will jam the memory instead of cleansing the memory. You have a firewall on your computer so it is more important to avoid these unexpected issues.
In the meantime, I am sure you understand very well what is the firewall? How does it work and why it is necessary? We hope you will use Firewalls on your computer. You know how much it is necessary.
