A relay is a switch used to control high-voltage devices such as fans, TVs, refrigerators, ACs, etc., with low-voltage devices such as microcontrollers. Wi-Fi is a technology used to provide network connectivity with the Wi-Fi modules to access the internet. Port forwarding is a method in Wi-Fi technology used to connect a specific device or computer within a private local area network. HyperText Markup Language (HTML) is a standard markup language that is used for developing web pages. There are different editors/tools available to write the HTML program. Even we can write the HTML program in notepad and save the program with an ‘.html' extension. Arduino IDE is an open-source platform used to write the programs for different microcontrollers, such as Arduino Uno, Arduino Mega, Arduino Mini, NodeMCU, etc. The Arduino IDE supports different types of programming languages such as C, C++, and Java. Arduino IDE contains majorly two functions such as ‘void setup' and ‘void loop.' Here ‘void setup' function executes for one time, whereas the ‘void loop' function executes continuously.
The World Wide Web
Published in Akshi Kumar, Web Technology, 2018
Technically, the Web is a set of technologies that allow information on the Internet to be linked together through the use of links, or connections, in documents. The language used to write these documents with links is HTML (Hypertext Markup Language). Let us first understand the notion of hypertext, a term that was first introduced by Ted Nelson. The standard way to read a book is in a linear fashion, starting from page one. The concept of hypertext allows a person to read or explore in a nonlinear fashion, as it contains “links” to other text. By following the links, the reader is not constrained to follow any particular order. Moreover, hypertext may contain links that do not necessarily lead to other text, but instead to audio or video files.
Interactive Devices and the Internet

Whereas the Internet is the global system of computer networks connected by a common protocol (a “network of networks”), the World Wide Web is an information space consisting of documents and other resources connected by hyperlinks. The World Wide Web can be accessed via the Internet. Web pages are documents formatted and annotated using hypertext mark-up language (HTML). Like documents on a word processor, they can contain images, video, and other media. The hyperlinks enable users to navigate between web pages. Each web page has a Uniform Resource Locator (URL) informally termed a web address. The URL can be entered to locate the desired page, if the URL is known. More often, users employ search engines to locate web pages.

Using information available in the literature [39–42], application protocols are compared in Table 2. Each of the standards is divided into 4 categories: usage case; how it transports data; mechanism of data request and response; and finally, the mechanism to broadcast data. Prior to the comparison, it is helpful to appreciate HTTP REST, which has existed for a long time now and is quite well-established. The World Wide Web is based on the Hyper Text Transfer Protocol (HTTP). HTTP is a way to communicate data and file transfer. It is similar to hypertext documents, which include hyperlinks to other resources that the user can easily access. In a client-server model, HTTP functions as request-response protocol. For example, our web browsers are the client, and a computer hosting a website acts as a server. When a web browser submits an HTTP request to a server, the servers, in turn, respond with HTML files and other data.
