What is Firewall? Good or Bad? Explained in Detail

Namaskaar Dosto, is video mein maine aapko firewall ke baare mein bataya hai, aap sabhi ne internet use karte time firewall ke baare mein jarur suna hoga, ab maine aapko bataya hai ki firewall kya hai? firewall kya kaam karta hai? aur aapko firewall ki kya jarurat hai? Dosto firewall ek security ki layer hai jo aapko computer ko protect karta hai malicious attacks se, yeh ek hardware bhi ho sakta hai, aur software bhi ho sakta hai, aur firewall ki madad se administration bhi kar sakte hai, kyuki jaise kisi country mein koi specific service agar government ko block karni hai toh bhi firewall kaam mein aata hai, aap yeh video dekhiye aur aapko pata chal jayega ki firewall kya hai, aur internet use karte time aapko firewall use karna kyu jaruri hai. Mujhe umeed hai ki firewall ke baare mein banayi gayi yeh video aapko pasand aayegi.

[@AbdulRehman-yo2qn]

Technical Guruji is a useful channel when it comes to knowing the fundamentals of the computer technology and networks. My mother tongue is Punjabi/ Urdu. But I was brought up in the UK from a young age, therefore my English is not bad. And I am a university student. But I prefer watching these videos because there is no use of technical jargon and I can easily understand the concepts. Thank you Guruji
