In our digitally interconnected world, the inner workings of networks, along with the technologies that underpin them, are integral to our daily lives. This comprehensive guide delves deep into the intricate world of networks, the critical role of optical fibers, the pervasive use of wireless technology, and the magic of Wi-Fi that connects us to the digital realm.

Section 1: How Networks Work

1.1 Unveiling Network Topology

Unveiling network topology is the process of identifying and mapping the structure of a computer network. This involves discovering devices, connections, and their relationships, which helps network administrators with troubleshooting, optimization, and security. The process includes device identification, connection mapping, and presenting the network’s layout in a visual format for easy management.

1.2 Protocols: The Universal Language of Networking

Protocols are like the universal language of networking. They’re sets of rules and conventions that dictate how devices communicate and exchange data in a

Researchers at Carnegie Mellon University have repurposed a common piece of tech found inn virtually every household into a tracking technology.

They used radio signals from WiFi routers to detect and track the three-dimensional shape and movements of human bodies in a room. They didn’t have to use any cameras or expensive LiDAR hardware.

“We believe that WiFi signals can serve as a ubiquitous substitute for RGB images for human sensing in certain instances. Illumination and occlusion have little effect on WiFi-based solutions used for interior monitoring. In addition, they protect individuals’ privacy and the required equipment can be bought at a reasonable price. In fact, most households in developed countries already have WiFi at home, and this technology may be scaled to monitor the well-being of elder people or just identify suspicious behaviors at home,” the authors wrote in their study, which is yet to be

A Quick Guide to How Your Home Network Works

A Quick Guide to How Your Home Network Works

Using your home network is as easy as typing in a password and opening your Netflix app to watch a movie, but your network and everything that’s needed for it to work so seamlessly are probably the most complex and unique devices you own.

Home networks exist to let digital devices talk to each other and to other devices out in the world over a global network called the internet. While you don’t need to understand precisely how your home network functions to enjoy it, spending some time under the hood will both give you an appreciation for the tech and make troubleshooting problems that come along easier.

Your Home Network Is a Mini Internet

The internet is short for ‘internetwork’, a global network of connected LANs (Local Area Networks) that includes web servers, streaming and cloud services, gaming servers, and much more.

Your home network is the same thing,
