In this insight article, we'll answer the most important and intriguing questions about how the internet works, which often arise among novice users.
Today, for most of us, the internet seems like a given - an extremely familiar technology, making it nearly impossible to imagine the modern world without it. Moreover, thanks to modern smartphones, most of us have access to the World Wide Web from almost anywhere.
However, not everyone even understands the basic principles explaining how the internet operates. This applies to both everyday users and owners of large traditional companies just starting to consider the benefits of IT technologies for their business and its digital transformation.
That's precisely why we decided to answer key questions about the internet and its operation. We won't delve into technical details that are likely to be confusing for many of our readers. Instead, we'll briefly address each question in the simplest terms possible.
What is the internet? The internet consists of billions of various devices interconnected with each other. It's somewhat like a giant web where each node represents a computer or any other gadget, and the individual strands are channels for data transmission back and forth.
Why are IP addresses needed? Every device connected to the internet is assigned a unique number composed of several digits separated by periods. It's like the address of your home but is intended to make it easier to locate a resource on the World Wide Web.
Why are domain names needed? To access a specific site, you can also enter its IP address into the browser's address bar. However, for ease of finding the desired information, it's simpler to use understandable domain names made of straightforward words. These are deciphered through DNS and translated into IP addresses.
What constitutes a request? When you want to visit a particular site, your computer sends a special request to the server where the data is located. Like a letter, it reaches the specific address through a multitude of routers and then returns with the necessary information.
How is information transmitted on the internet? In reality, a variety of methods are used to transfer information across the World Wide Web. For instance, continents are connected by vast underwater cables, while satellites convey data where cables are absent. At home, you most often use Wi-Fi, and outside, cellular network technologies.
How safe is it to use the internet? Sadly, it's not the safest place, rather than just a realm of boundless knowledge. It's riddled with various threats, including malicious software and fraudsters. Encryption and other security measures are used for protection.
What are cloud technologies? These are essentially servers that store user information and provide access to it via the internet. For example, photos from your smartphone often automatically upload to cloud storages like iCloud for iPhones and Google Photos for Android.
Who controls the internet? In reality, there isn't a main computer or a singular organization that governs the entire World Wide Web. The internet is a decentralized system built on standards and protocols to which all network participants must adhere.
How has internet access changed communication? The internet has become the tool that has radically transformed human communication. Thanks to it, platforms for instant messaging (iMessage, WhatsApp, Messenger), video conferencing (Google Meet, Zoom), and social networks (Facebook, Twitter) have emerged.
Today, virtually all communication between people takes place over the internet. This applies not only to personal interaction but also to the relationships between businesses and their clients. Therefore, it's important for companies to focus on their online presence rather than anything else.
Why is the conversation about internet security important? As the number of internet users grows, so does the number of threats associated with it. Hence, ongoing discussion about the internet, with many conversation questions about safe network use, is very important.
When clicking on links online, one should be aware of the possibility of fraud; when opening websites, think about phishing; and when downloading anything, it's crucial to ensure a minimal chance of encountering a virus. Understanding the basics will help protect personal data and avoid potential threats.
How has internet search changed the approach to learning? The World Wide Web has provided access to an unlimited amount of content with just a click. Every topic on an educational portal helps both students and teachers to understand any subject more deeply, not limited to just textbooks.
Moreover, the internet offers access to platforms for discussing any questions without exception, allowing the exchange of ideas, asking unconventional questions, and receiving answers. Such discussions stimulate critical thinking and knowledge exchange.
How do social networks affect public opinion? Every page on a social network or other internet service allows for the rapid dissemination of facts that can change public opinion. Therefore, it's very important to remember critical thinking and question various viewpoints.
How does the government regulate the internet? Government bodies most often monitor online activities through each internet service provider and other structures. This includes everything from simple traffic observation to the complete banning of certain websites.
What role do apps play in using the internet? Each mobile or desktop app simplifies access to banking services, social networks, messengers, YouTube, and any other resources. Typically, they are optimized for specific tasks and ease of use on a particular device.
Overall, the internet is a remarkable human creation, resulting from the collaboration of many individual minds and even entire countries. It has already transformed our world and continues to do so. If your company isn't represented on the internet today, it's significantly behind. In this case, it needs to expedite its digital transformation as soon as possible.
Our company is a space where ideas flourish and transform into reality.
