What is a digital twin and why it’s important to IoT

Digital twin technology has moved beyond manufacturing and into the merging worlds of  Internet of Things, artificial intelligence and data analytics.As more complex “things” become connected, with the ability to produce data, having a digital equivalent gives data scientists and other IT professionals the ability to optimize deployments for peak efficiency and create other what-if scenarios.What is a digital twin? A digital twin is a digital representation of a physical object or system. The technology behind digital twins has expanded to include buildings, factories and even cities, and some have argued that even people and processes can have digital twins, expanding the concept even further.To read this article in full, please click here

What is DNS and how does it work?

The Domain Name System (DNS) is one of the foundations of the internet, yet most people outside of networking probably don’t realize they use it every day to do their jobs, check their email or waste time on their smartphones.At its most basic, DNS is a directory of names that match with numbers. The numbers, in this case are IP addresses, which computers use to communicate with each other. Most descriptions of DNS use the analogy of a phone book, which is fine for people over the age of 30 who know what a phone book is.[Get regularly scheduled insights by signing up for Network World newsletters.] If you’re under 30, think of DNS like your smartphone’s contact list, which matches people’s names with their phone numbers and email addresses. Then multiply that contact list by everyone else on the planet.To read this article in full, please click here

What is IPv6, and why aren’t we there yet?

For the most part the dire warnings about running out of internet addresses have ceased because, slowly but surely, migration from the world of Internet Protocol Version 4 (IPv4) to IPv6 has begun, and software is in place to prevent the address apocalypse that many were predicting.But before we see where are and where we’re going with IPv6, let’s go back to the early days of internet addressing.[ Related: IPv6 deployment guide + How to plan your migration to IPv6 ] What is IPv6 and why is it important? IPv6 is the latest version of the Internet Protocol, which identifies devices across the internet so they can be located. Every device that uses the internet is identified through its own IP address in order for internet communication to work. In that respect, it’s just like the street addresses and zip codes you need to know in order to mail a letter.To read this article in full, please click here
