Cloud Computing Basics
Everyone uses cloud computing resources these days! You are probably utilizing a cloud computing service to access your web-based email account, for example. Or, maybe you use a cloud data storage system such as Google Drive or Microsoft's OneDrive. If you are a Netflix subscriber, you are using their cloud-based servers to stream those adventure-filled movies over the web. Yes, we use lots of cloud computing services indeed, and yet, very few of us really understand what cloud computing means. Hopefully, this quick guide will explain the basics.
"Cloud computing" is, in fact, just a catchy name that was invented by a clever marketing team. There is nothing cloudy about "cloud computing", really! At a basic level, cloud computing systems consist of a network of powerful servers that have various applications installed on them. So, why do we need these cloud servers, in the first place?
Let's assume that you run a small business. You sell shoes online, for example. Since you do such a great job, all your friends and relatives purchase shoes from your website...
It may be just an urban legend, but it looks like Wi-Fi is the abbreviation for "Wireless Fidelity". It's a friendlier name for the IEEE 802.11 family of wireless standards. But how does Wi-Fi work in the first place? Let's find out!
Just like walkie-talkies, Wi-Fi devices utilize radio waves. In a typical scenario, a router broadcasts 2.4 GHz radio waves, and your laptop, tablet or phone includes a wireless adapter which is able to receive and decode them. We are talking about a two-way data exchange, of course; your device will send and receive data packets as well.
Each device that can connect to a Wi-Fi network includes a wireless module. If you own an older laptop, which doesn't include a Wi-Fi adapter, you can purchase one separately, and then plug it into one of the available USB ports. Sometimes signal range is too small; in this case, you may need to use an external Wi-Fi antenna and an SMA cable or adapter, or install a signal repeater. Be sure to follow the links if you want to learn more about these topics...
If you are like most people, you can make use of almost everything that the Internet has to offer. You are able to visit websites that interest you, get and send emails, connect with your friends using social media sites, and more. And yet, very few people are able to understand the inner works of the Internet. It's not a surprise, because the web is a complex system. Fortunately, by the end of this guide, you will be able to understand all its key aspects.
The very first, and one of the most important components of the Internet is... a huge network of cables! Yes, you can't talk about the web without discussing about submarine communication cables.
It is true that wireless Internet is now the reality. We've gotten Wi-Fi and satellite-based connections, for example. And yet, the Internet's infrastructure is heavily based on cables. Without them, servers would be unable to communicate...
Did you know that the number of Internet users worldwide has grown from one billion in 2005 to almost four billion people in 2018? East Asia is the global leader, having about one billion Internet users, while the U.S. occupies the fourth spot, with almost 350 million users.
