  From Tarakeswar to Five-Star Hotels — My Journey, My Identity, My Question My name is Kamal Roy. I come from a simple middle-class family in the small town of Tarakeswar, West Bengal. My father is a farmer, and my mother is a homemaker. Generations ago, my great-grandfather was a wealthy man during the British era, but time changed our circumstances. However, my dream has always been different. I don’t want to be known by my father’s name. I want my father to be known by mine. My journey began in 2007 after completing my Computer Hardware & Networking course from George Telegraph. I started with a stipend of just ₹1,600 at a small company.

I moved forward, learning, struggling, and growing. From earning ₹5,500 at Theta Computer Service Pvt. Ltd. to ...

It is primarily used to connect end-user devices such as desktop computers, printers, IP phones, or other client devices. Traffic coming from these devices is untagged , and the switch automatically assigns that traffic to the VLAN configured on the port. In simple terms, an access port acts as the entry point for user devices into the network , ensuring that the device communicates...

Below are some practical steps that can help identify and manage such situations effectively. 🔹 🔵 1. Check DHCP Logs Regularly The DHCP server automatically assigns IP addresses to de...
