Really helpful video sir👍
Expecting more videos sir

[@ajbaskar8440]

Sir i have one doubt. Lot of vpn apps is available.. These apps also using same concept ah. Because once we connected to the vpn server after that our public ip will be changed.. But you said after connect to the vpn server we can access the inside of vpn server systems only. ..I'm really confused... So Can you please explain more clearly

[@collectivaknowledgeacademy]

Good question. The VPN is primarily intended to access private computers of company or home computers through internet. At the same time we can access the internet sites also without any restrictions. There are few settings for that. Thanks.

[@sindujasindu976]

Sir what mean safe mode and normal mode

[@collectivaknowledgeacademy]

In safe mode only basic services are enabled and started. In normal mode all the services will be started. That's the difference. Suppose we install a new software after that the system gives trouble. Then we need to start in safe mode, remove the software or the driver or the patches installed and then restart the system. Then everything will be fine. Thanks.
