There is no doubt that one of the most frustrating situations that must pass a netizen is when you want to access content on a web page, and is no longer available.
Imagine the situation. You are anxious to see what is in the content of certain website and when you come, you get the irritating message: Error 404. The Page Was Not Found.
What has happened? What you wanted just disappeared?
Sometimes yes; sometimes not. To understand this phenomenon, it is first necessary to know is that this 404 error.
That means the famous Error 404
On the web there are clients (a PC with an installed Internet browser, a software such as Edge, Chrome or Firefox) and servers (big computers with one or more processors, with large memory and hard disk space). They are always carrying a conversation: the first asks; the second respond to the questions.
In general, the medium used to maintain this dialogue is the HTTP – HyperText Transfer Protocol, a system that can send and receive text files, images, audio and video.
Thus, when you enter a website, this conversation starts. Your browser requests data on the web site you’re looking for a particular server. The first answer that comes, and you do not see, is a data packet containing status codes, i.e. information on how things are going. If they go wrong, the fatal 404 error arises then.
Naturally, you’re eager to know what these numbers mean. The first number (4) suggests two problems: either the web address is not available or no longer exists. The second number (0) indicates a spelling error. The last number, (4 again) leads to a specific abnormality called “unauthorized access”, i.e., can only enter the page if you had a password.
The 404 has a curious history. Its origin dates back to the offices of CERN – European Laboratory for Particle Physics – based in Geneva, Switzerland. In the early Internet, circa 1980, on the fourth floor of CERN, in room 404, it was assembled a database, controlled by three people.
They controlled manually the file request and then transferred to those requesting these files. When mistakes happened, they warned: “Room 404 – File Not Found”. Later, the term was incorporated into the online world by the English physicist Tim Berners-Lee, the creator of the web.
Error 404, however, is no reason to give up your searches. With the following tips and some patience maybe you can find what you want.
Access the page again or refresh the page. Sometimes the Error 404 is no more than a false alarm.
Search spelling errors in the address you typed and correct them. Also try to change the extension page. For example, instead of HTML, use HTM or vice versa. Also try other extensions such as asp and PHP.
Write to the Webmaster of the site. At least you’ll be doing him a favor by alerting on broken links.
