Let’s start with the very basic. What is a browser? We all have used it in our desktop, or mobile devices. Browser is essentially a software program created a simplified tool to present and explore the content of the world wide web.
Once you open the browser, you can browse the internet by following any hyperlinks or by using a search engine.
The primary function of a browser is to render HTML codes which are used to design the web pages. Every time it loads into a web page, the browser processes the HTML codes and renders them into the browser windows.
Basically, a webpage is a simple text file that contains various types of other files. But most importantly, the webpage contains HTML codes which dictate the look of a webpage. A typical web page contains hypertext documents and hyperlinks which allows us to move from one web page into another.
URL stands for Uniform Resource Locator. It is the address of a resource on the internet. A URL indicates the location of a resource as well as the protocol that is used to access it. It also contains the IP address, port number, fragment identifier and location of the resource. Most URL is used to refer to a webpage (HTTP) however, it can also be used for file transfer (FTP), email (emailto) and database access (JDBC).
HTTP and HTTPS
HTTP (Hypertext transfer protocol) and HTTPS (Hypertext transfer protocol secure) are the underlying protocol used by the worldwide web with the latter being the extension of the first. The protocol defines how messages are formatted and transmitted, and the actions that the web server or browser should take in response.
The difference between both of them lays between whether there is a password that is being encrypted. HTTPS works in a conjunction with another protocol called secure sockets layers. This is used to transfer data safely.
HTTPS is hugely used to protect certain data from hackers and mobile security.
HTML (Hypertext Markup Language) is the markup language that constructs the web pages. HTML is used only to display the data and focuses on how the data looks. HTML is the combination of hypertext and markup language. It defines the link between web pages.
XML stands for Extensible Markup Language. It is a language that enables a user to define a representation of data or data structure where values are assigned in each field in the structure. There is a set of rules that defined the XML and the user has to abide by them. A minor error will not be tolerated as it would cause an error.
XML focuses on transport and store data. It provides the framework to define HTML.
XML itself is used to create both web pages and web applications.
Internet Protocol address is a numerical label assigned to each device connected to a computer network that uses internet protocol for communication. It functions as a host or network interface identification and address of a certain location. The growth of the internet has pushed the IP address to evolve its bits number.
Antivirus or known as anti-malware is a computer or mobile program that is used to detect, prevent and remove malware. It has evolved from its original purpose, the antivirus can now provide protection against hijackers, keyloggers, spam, and any other online threats.

Router is a networking device that forwards data packets between computer networks. A router directs the traffic of the internet. Data that is sent through the internet is sent through data packet. These data packets are forwarded from one router to another router through the networks.
Email is the shortened form of an electronic mail. It is one of the main forms of communication that is widely used nowadays. It operates across internet networks. The email system is based on store and forward model, in which the information is sent to an intermediate station where it is kept and sent later at a time to its final destination.
