Semantic Elements Review HTML5 semantic element add more information about its related contents; such as providing information to HTML elements in the web document. These are commonly use semantic element. <header> element is use to group elements that appears at the beginning of a web page. <article> element is the main content of that page. <section> element is use to group segments of a large content or article. Mainly use to group <h2> element and <p> element that appears in a large article. <aside> element marks part of a page that's tangential to the main page content. <nav> main elements site and page navigation. <footer> contains information about a website that usually appears at the end of a web page. <figure> contains an image that add information to a web page; <figcapture> marks caption text associated with an <img> element. <fieldset> marks a group of related form fields and labels <legend> marks a heading describing the associated field.

Hi guys will explain TCP/IP, IPv4 and IPv6, https and http, and DNS infrastructure in my next post. Remember HTML is still a programming language use to create a software, then script are used to design the applications that runs it. ![]() |
Abolarin91:Do you mean adsense? It doesn't take time to be activated. Is it a CMS website, let me know. |
SegFault:That's true bro |
Shepherdd:That's true bro, php applications runs on Facebook website, because it needs to communicate with database on a server; every programmer should know that. It is easy to mention the technology you used for your website but can not release the source code. Note: Not the one rendered by web browser.. |
SegFault:Wikipedia will deceive you, don't rely on their information. Facebook have high level of security, because of that, they will never release the programming language they use. |
Saneesk:Facebook and Amazon software engineer have high analytic and technical skills in solving critical problems. I will recommend you develop your analytic skills by studying your basic algebra, then you can start with HTML5/CSS3, javascript and C++. No company will release their source code, don't mind folks saying Facebook is built with this and that language. |
Tim1212:I will explain this news� When you register for a domain name from a company; you will be assigned a unique address known as URL URL contains the schema "http or https ". https if you paid for SSL certificate. A secured Protocol. Followed a unique address/domain name or server name. Domain name comes with an extension, .com, .net, .org etc. That is a unique address on the web. The web space, also known as storage space or disk space, generally refers to the amount of space on a web server that is allocated to website owners by the web hosting companies. It is made up of the total quantity of all text files, images, scripts, databases, emails and other files related to your website. Web server is a computer that delivers a web document to the client computer when requested. When you rent a web space from hosting companies They will provide you with a unique IP address (Internet Protocol) DNS, which stands for domain name system, is an Internet service that convert domain names into IP address. For example, when you visit diib.com it must look up the corresponding IP address to that hostname behind the scenes. This query is performed by a Domain Name Server (DNS server) or servers nearby that have been assigned responsibility for that hostname. A DNS server maintains a directory of domain names and translates them to IPs. DNS hosting companies can be attacked by making repeated requests to server, which will overwhelm the system. From there it becomes vulnerable to attack any website the hacker targets. The research institute contacted DNS company to strengthen their server. |

Israeli researchers stop cyberattacks with discovery of major DDoS In addition to their study, the researchers also contacted Google, Microsoft, Cloudflare, Amazon, Dyn (now owned by Oracle), Verisign, and Quad9, leading them to update their DNS software. Israeli researchers from Tel Aviv University (TAU) and the Interdisciplinary Center in Herzliya have discovered a previously unknown Distributed Denial of Service (DDoS) exploit, potentially thwarting future attacks using this DDoS technique, according to a press release from TAU on Thursday. As part of a new study, Prof. Yehuda Afek of TAU’s Blavatnik School of Computer Science, Blavatnik Interdisciplinary Cyber Research Center and the Checkpoint Institute and Prof. Anat Bremler-Barr, Vice Dean of IDC's Efi Arazi School of Computer Science, with the help of TAU doctoral student Lior Shafir, provide an in-depth description of the new technique that may have allowed a small number of computers to carry out a DDoS attack on a massive scale, which is dangerous for critical infrastructure. In addition to their study, the researchers also contacted Google, Microsoft, Cloudflare, Amazon, Dyn (now owned by Oracle), Verisign, and Quad9, leading them to update their DNS software in response to the threat. Consequently, , Prof. Afek and Prof. Bremler-Barr have been responsible for stopping hundreds of cyberattacks. Referencing a major cyberattack in 2016 that crippled Amazon, Reddit, Spotify and Slack along the US east coast, the researchers suggest the cause may have been due to the weakness within the DNS. “The DNS is the essential Internet directory. In fact, without the DNS, the Internet cannot function. As part of a study of various aspects of the DNS, we discovered to our surprise a very serious breach that could attack the DNS and disable large portions of the network,” Prof. Bremler-Barr explained. "The attack in 2016 used over 1M IoT devices, whereas here we see the same impact with only a few hundred," added Prof. Afek. "We are talking about a major amplification, a major cyberattack that could disable critical parts of the internet.” Dubbed “NXNSAttack” (Non Existent Name Server Attack), the newly discovered technique takes advantage of exploits in common DNS software that converts the domain names you click or type into the address bar of your browser into IP addresses. The NXNSAttack may lead a DNS server to do hundreds of thousands of requests based on the hacker's one request, crashing the system. “To mount the NXNSattack,” Prof. Afek notes, a hacker acquires for a price or simply penetrates, an authoritative server, redirecting the resolver to send hundreds of thousands of requests to the servers. “The attacker sends such a request multiple times over a long period of time, which generates a tsunami of requests between the DNS servers, which are subsequently overwhelmed and unable to respond to the legitimate requests of actual legitimate users.” “A hacker that discovered this vulnerability would have used it to generate an attack targeting either a resolver or an authoritative DNS server in particular locations in the DNS system. In either case, the attack server would be incapacitated and its services blocked, unable to function due to the overwhelming number of requests it got. It would prevent legitimate users from reaching the resources on the Internet they sought,” Shafir described. "Our discovery has prevented major potential damage to web services used by millions of users worldwide. The 2016 cyberattack, which is considered the greatest in history, knocked down much of the Internet in the US, but an attack like the one we now prevented could have been more than 800 times more powerful,” concludes Prof. Afek.
