An internet domain is, in short, the name of your website. It is a textual label that identifies a set of devices or internet services, connecting them into a unique administrative-technical entity. A domain consists of a series of alphanumeric segments separated by dots, in accordance with internet standards. Each segment can contain numbers (0-9), letters of the English alphabet (a-z), and hyphens (-). The length of a segment must be between 2 and 63 characters, and it cannot start or end with a hyphen.

The concept of web hosting refers to a company that leases its computer/server to store your website and provide internet connectivity, allowing other users to access files on your website. In most cases, these hosting companies will handle server maintenance tasks such as backups, root configuration, maintenance, disaster recovery, and so on.

HTML (HyperText Markup Language, a language for marking up hypertext) is a descriptive language specifically designed for describing web pages. It allows for the easy separation of elements such as headings, paragraphs, quotes, and the like. In addition, the HTML standard includes elements that provide more detailed information about the document itself, such as a brief document description, keywords, author information, and so on. These details are commonly known as metadata and are clearly separated from the document’s content.

CSS (Cascading Style Sheets) is a formatting language used to define the appearance of elements on a web page. Initially, HTML was responsible for defining the complete look, structure, and content of a web page. However, starting from HTML version 4.0, CSS was introduced to specifically define the concrete appearance, while HTML continued to serve the purpose of defining the structure and content.

PHP, which stands for Hypertext Preprocessor, is a specialized scripting language primarily designed for creating dynamic web content and is executed on the server side. PHP has gained popularity due to its simplicity and syntax inherited from the C programming language. Over time, the language has expanded and gained capabilities for object-oriented programming, particularly since version 5.0. It is similar to the C++ language in that it allows both pure procedural programming and, at the same time, supports the use of classes and other object-oriented programming concepts (inheritance, abstract classes and methods, interfaces, etc.).

Search Engine Optimization (SEO) is the process of improving the quality and quantity of traffic to a website from search engines through natural (organic or algorithmic) search results. Typically, the better a site is ranked (for example, appearing among the first in search results), the more traffic will be redirected to it from search engines. SEO can apply to various types of searches, including image searches, local searches, and more. As an internet marketing strategy, SEO considers how search engines function and the terms people search for. Website optimization primarily involves altering the content and HTML coding to improve its ranking for specific keywords and remove obstacles to the indexing of website content by search engines.
