The Internet is designed to allow data to flow quickly and reliably between billions of devices worldwide. Within countries, this is done by terrestrial fiber-optic cables that stretch along roads, and through towns and villages. But how does your video call from Kyiv to Los Angeles go almost without delay? The answer is a fiber-optic communications system that connects continents at speeds that would make even a cheetah uncomfortable.

And no, it's not about satellites, as half of internet users think. Nearly 99% of international traffic runs through undersea fiber-optic lines, the digital arteries stretching across the oceans.

• There are more than 500 such cables/
• Their total length — 1.4 million kilometers.
• This is enough to wrap the Earth around the equator as many as 32 times!"

DDoS (Distributed Denial of Service) — is an attack where your server or website is flooded with a huge number of requests from multiple devices at the same time. Imagine, it's like having thousands of visitors trying to enter your small cafe with 10 tables at the same time - you simply don't have enough resources to serve them all. And your regular customers won't even be able to get to the door!

Let's divert a little from serious topics and learn a few funny stories about IP address usage. Perhaps you may have heard some of them before. But in any case, a good mood is guaranteed for those who finish reading!!

.NET 9 continues Microsoft's tradition of developing its ecosystem by offering improvements in key areas: security, performance, and ease of development. This version is aimed at simplifying the work of developers, increasing the reliability of applications, and adapting to modern industry requirements. Let's analyze the main innovations of .NET 9 and their impact on development

National domains are a true digital geography, reflecting the diversity of our world. Two characters at the end of a website address seem like something ordinary. But in these letter codes is a whole world of unexpected stories, successes and surprises.

Ready for a fascinating journey through the domain zones that became stars? Let's go!

Caching– is one of the most popular and effective approaches used in software development. Its essence is to reuse already obtained results of long or heavy operations, avoiding their repeated execution. After a complex task is completed, the result is stored in a cache and retrieved from there when it is requested again, instead of having to perform the same operation again. This approach is designed to make it much easier on the server and speed up the application.
