Can the radiation emitted by electronic devices affect your body and make you feel terrible?

This joke video is about how Internet Service Providers (aka ISPs, internet companies, telecommunications companies, etc) violate the basic axioms of Zermelo-Fraenkel set theory. Like the axiom of choice (sometimes Well-ordering...

Este vídeo de broma es sobre cómo las compañías telefónicas violan los axiomas básicos de la teoría de conjuntos de Zermelo-Fraenkel, como el axioma de elección (o el axioma de buena ordenación, a...

After 14 years of going unnoticed, a vulnerability in Wi-Fi security was published last week. It's a serious problem, but it's already in the process of being fixed.

Once your smart devices can talk to you, who else are they talking to? Kashmir Hill and Surya Mattu wanted to find out -- so they outfitted Hill's apartment with 18 different internet-connected devices and built a special router to track...

If you want to improve your wireless internet signal, we've got a few things to keep in mind.

In this video, observe a practical demo of configuring DR and BDR in OSPF.

In this video, learn the key differences between dynamic routing protocols and static routes.

In this video, see how default routes and load balancing are configured in a network to ensure optimal traffic distribution.

In this video, gain an understanding of how ACLs work and their role in filtering traffic based on IP addresses and protocols.

In this video, we introduce Access Control Lists (ACLs), a powerful tool for controlling network traffic and enhancing security.

In this video, learn about FHRPs such as HSRP, VRRP, and GLBP, which provide fault tolerance at the first hop in routing.

In this video, explore the importance of network redundancy and how it enhances network reliability.

In this video, we introduce HSRP, a protocol that provides network redundancy by allowing multiple routers to back each other up.

In this video, understand how to configure Cisco devices to use an external DHCP server.

In this video, explore how to configure a Cisco router or switch to act as a DHCP server.

In this video, we introduce DHCP, the protocol that automates the assignment of IP addresses to network devices.

In this video, we introduce Inter-VLAN routing, explaining how traffic moves between VLANs in a network.
