What is FireWall?

dosto fire wall ka sida consept computer and network security se hai. fire ka matlab aag(आग)
and wall ka matlab diwal(दीवाल ) matlab ek aisa diwal jo ki aag se hame bachata hai. aur yaha aag ka malware(virus, trojan, worm & treads) and diwal ka matlab secure connection hai. matlab ek aisa connection jo ki hame virus malware se bachatra hai. dosto jab ham apne computer on karte hai. tab hamare system me bahut sare attack hone ka dar rahta hai. lekin agar ham firewall ko enable kar dete hai to jo hamare system me attack hota hai, use firewall rok deta hai. aur side bhasa me bat kare to ya hamare system ke liye security guard ke tarah hai.

example:- jaise dosto ham (WAN)wide area network se internet use kar rahe hai, lekin agar koi hacker LAN(local area network) se hamare system me attack akrne ki kosis karta hai. to firewall use block kar deta hai. aur hamare system se dur rakhta hai.
