The Domain Name System: How It Works

The Domain Name System (DNS) is the backbone of the Internet. Without it, you wouldn’t be able to access websites or send email unless you memorized IP addresses. It’s kind of like a phone book for the Internet: it translates domain names into IP addresses so that networked devices can understand each other. In this article, we’ll explain how DNS works and why it’s important for understanding how the world wide web works.

What is the Domain Name System (DNS)?

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services and other resources connected to the Internet or a private network. The domain name system translates human-friendly computer hostnames into IP addresses. In order to achieve this, it must maintain data about that mapping. This data is stored in a set of interrelated databases called zones.

The Domain Name System was created in 1983 by Paul …

A Beginner’s Guide To The Domain Name System (DNS)

The Domain Name System (DNS) is one of the most important elements of the internet, but it’s also one of the most complex. Understanding how DNS works not only helps you get around in your browser, but also empowers you to better understand and troubleshoot websites that run on servers. With this beginner’s guide to DNS, I’ll introduce you to everything from basic concepts like domain names and domain name servers to advanced topics like name records and record types. We’ll cover authoritative vs. recursive name servers; how they work together; what changes when a domain is transferred; why some sites give you bad results when they’re not responding properly; plus much more!

The domain name system, or DNS, is a system of computers that translates human-readable website names into machine-readable IP addresses. In other words, when you type “google.com” into your browser’s address bar and press Enter, the DNS …

What Network Analysis Can Teach You About Human Resources

Network analysis is a technique that can be used to study relationships among people. It’s used in many fields, including marketing, social sciences, and biology. I’ve always been interested in the ways that network analysis can help us understand human behavior, so when I discovered how much it relates to human resources (HR), I was very excited! After all, HR is all about understanding people’s relationships with each other—and understanding how these relationships affect outcomes like employee engagement or turnover rates would be hugely useful for anyone working in this field. As an HR professional myself and someone who loves learning about both technology and psychology (two things that are often at odds with one another), I thought it would be fun to explore this topic further by interviewing experts on both sides of the equation: tech pros who have helped build tools using network analysis techniques as well as …

What Networks Really Are And Why You Should Care About Them

Networks represent relationships between people, places and things, but they’re also different from other types of relationships because they have their own unique patterns and characteristics that can be studied and understood.

Understand Networks With This Simple Image

When you think about networks, you probably imagine all the different ways people use them. But what are networks really? What do they look like? And how can you make sense of them? As it turns out, there’s a simple image that can help answer all of those questions.

Networks can look like anything.

Networks are everywhere. They can be physical, virtual or conceptual. They can be made of people, computers or other things like ideas, energy and water. Networks can be highly structured and organized or very loose and chaotic; they may have formal rules (like laws) or informal ones (like social norms).

Network diagrams have a universal structure.

The structure of a network diagram is simple and universal. The nodes, or vertices, are represented by circles and the links between them are drawn as lines. Most diagrams also have an arrow at one end of each link to …
