In the twenty-first century, technology is deeply involved in every step of our lives. From food orders to shopping, entertainment, and even learning we’re using everything on a website or app. And the developers are creating all these apps or websites.



So it would not be a mistake to say that web development is one of the most critical and essential tasks of the 21st century.


From the outside, this field can seem complex and incomprehensible. But that doesn’t mean you should never explore this potential field! So for those who are interested, starting from the very basics of web development, a clear idea will be given in this article.


What is web development ?


The task of creating a website or application for the Internet is actually web development. Website design but not its concern, the coding, programming, and ancillary work for website creation and maintenance of its functionality ওয়েব these are web development.

From the most straightforward static web pages to social media platforms or apps, e-commerce websites, or online encyclopedias — all of the online tools we use every day to build everything in web development.

Is the demand for web developers really high?


At present, the demand for web developers is much higher due to the violence of websites and apps. We can see the reflection of this in the job market. Online presence is essential for all organizations now as well as offline. And to ensure that you need your own website, or app. Everyone has to be responsible for creating and maintaining these web developers.

The US Bureau of Labor Statistics says the demand for web developers will grow by 7% in the next ten years, more than any other job.


The Corona epidemic of 2020 has turned the corner of life, and that turn is also towards increasing the role of web developers. In the work-from-home revolution, people’s online presence is only growing. Everyone has to do everything online, and so the demand for web developers is increasing by leaps and bounds.


Considering the job market and future prospects, now is a great time to be a web developer. Communication with people close to you, shopping, education, entertainment — everything is becoming more and more website dependent, and so the world of the future will largely depend on web developers.


So let’s start understanding the field of web development a little better.

Some basics of web development

Before we start discussing Web Development, let’s take a look at “Web.” Although this “web” or web that surrounds the earth is invisible to our eyes, a vast system plays a role in its effectiveness.


First, the web of information connected around the world is called the WWW or World Wide Web.


The three parts of the World Wide Web technology-


Browser for displaying information

Server for storing data

And protocols for connecting browsers and servers



We regularly use Google Chrome, Microsoft Edge, Opera Mini. These are but one browser. These software applications send requests to collect information from the World Wide Web and display the information on our PC screen.



The system that collects and provides information to the browser is the server. Some servers store the data themselves, while some browsers are directly connected to where the data is stored. As soon as the request is received, the server finds the information and sends it to the browser. As part of the server, there is a software application, which sends the information in a format that can be displayed in the browser. Examples of some of the most widely used servers are Apache, Nginx, or IIS.

Protocols are some established set of rules for the exchange of information. It facilitates the exchange of information between two devices on the same network, or between browsers and servers, by default. The protocol determines how the communication between the client and the server will be. When you run the Internet, the word ‘HTTP appears at the beginning of all addresses, but it is a protocol.

So what is a website?


This is what we have been talking about on the server for so long; this is what the browser displays as a webpage. And a website is basically an integrated version of some webpage.


After you enter an address in the browser’s address bar, the browser sends it to the server via the protocol. The server locates that address, collects information or files from there, and sends it to your browser in the form of a displayable page. And then, you see the desired website on your screen.

Which is the URL?


Simply put, what we type in the browser’s address bar is the URL—complete Uniform Resource Locator.


It has certain parts that indicate its various features. For example, is a URL. We already know that ‘HTTP is the protocol, and www means you are going to the World Wide Web.


The part is the domain name that the server appoints, and file.html is the file whose information you want to access. The device you are accessing through the URL can also be shown as an IP address.

What is meant by IP address?


In the middle of the discussion, we got a new term, which is IP address. The complete form of IP is Internet Protocol. An IP address is basically a string of numbers. All devices connected to the Internet have their own and unique IP address. It looks a lot like this – 123.45.321.1… (To know the IP address of your device, type “What is my IP Address” and search Google and enter the first links.)


All web servers, therefore, have their own IP address. It hosts information or files displayed as webpages, along with the hardware and software needed to access them in the browser.


These strings of numbers are replaced with domain names to make it easier for people to remember. For example, is a domain name. Knowing this part but we can reach Facebook; we don’t need to remember its IP address.

HTTP means


To give an example of protocol, we have learned that HTTP is a protocol. The complete form is the HyperText Transfer Protocol. It is a network protocol that, like other network protocols, determines how information is exchanged between client browsers and servers.


In HTTP, HyperText means hyperlinked attached document (hyperlink is the text or image where clicking will send the user to another document), transfer means sending the requested webpage from the webserver to the browser, which is byte, and prototype. It will be his custom to exchange information.


More such protocols may be File Transfer Protocol (FTP) or HyperText Transfer Protocol Secure (HTTPS) – all of which are used for the same purpose.

I found out about the website. Let’s start the discussion of web development.

What are frontend and backend?


When it comes to web development, the words “frontend” and “backend” come into play. The front end of a website or software is the side with which the client interacts. In other words, in the case of a website, the form that appears in the browser is the frontend. It helps frontend users to view a website, play videos on it, expand or minimize images.

On the other hand, the backend or server-side is the side that we clients or users do not see. The web’s digital infrastructure, which to non-developers would seem to be a mess of just numbers, letters, and weird symbols. Backend work is much more than frontend, and there are more ways to configure it.


These two issues will be discussed in more detail later.

Database technology


The database ensures that the files and content required for the website function are easy to find, sort, edit and save. Databases also run within servers, and most websites use a relational database system (RDBMS).

However, non-relational databases are also gaining popularity lately because it is more convenient to use if the data is of massive amount. It is seen to be used in the work of big websites.

What is CMS?


Content Management System or CMS is a web application or series of programs used to create and manage web content.


While CMS is not required to create a website, its plug-ins and add-ons enrich the website and are also very useful in maintaining the website. WordPress, Joomla, Drupal – these are some examples of CMS.

The difference between web development and web design


We often hear the term web design as well as web development, and apparently, the two may seem to be one thing. But in reality, the two are entirely different.


If we imagine a website as an automobile, then the web developer there will work with engines, wheels, gears. On the other hand, the designer will work on the visual aspect of the car – will decide the color of the vehicle, the design of the seat, or the layout of the control.


A web designer designs the exterior of a website. Exactly its layout, color scheme or font, decides what the scrollbar or menus will look like, where it will be if there is an ad – all these things.


And the developer’s job is to turn this design into a live and functional website. A frontend developer uses a web designer’s visual design to create a website using a variety of coding languages, such as HTML, CSS, or JavaScript. And the backend developer makes it fully functional from server to a browser.


In a word, a web designer is a website designer, and a web developer is a builder.

What does a web developer actually do?


So far, we have come to know the details of the website and also got a clear idea about the work of a web developer. Now let’s take that idea more clearly and broadly.


The job of a web developer is to create and maintain a website. That work can be in-house or freelance in any way according to the needs of the organization. The type of work he does depends on whether he is a frontend or a backend, or a full-stack web developer. Full-stack web developers specialize in both frontend and backend.


Web developers create a product tailored to the needs of their clients and website users. There they work together with stakeholders, clients, and designers — to make the vision, feel and function of the website a reality.


Again, bug identifying and fixing is a huge part of Web Development. In addition to developing, it is also the job of the web developer to optimize and improve the website or system continually.

So web developers are very efficient problem solvers, who constantly come up with timely solutions to various problems to keep the system running. Needless to say, they also have to master the programming language in detail.


With all this in mind, let’s take a look at the specific tasks of different types of web developers.

The work of a frontend web developer


The front-end developer codes the front end of a website or application. That is, they make backend data easily understandable, visually appealing, and functional for everyday users. They turn the designs given by web designers into the magic of HTML, CSS, or JavaScript.


Frontend developers implement the layout of a website, its interactive and navigational elements such as buttons, scrollbars, images, internal links — everything. The frontend developer also ensures the proper display of websites or applications in different browsers and devices.

They code websites so that they are adaptable to different screen sizes and types of devices, giving users a satisfying experience everywhere.


Frontend developers also do regular usability testing, fixing any bugs in the frontend. To do all this, they keep in mind SEO (Search Engine Optimization), Software Workflow Management.

Back-end web developer work


The backend developer builds and maintains the infrastructure needed to keep the frontend moving. There are basically three parts to it: server, application, database.


The code provided by the backend developers ensures smooth communication between the server application and the database. How do they do this? First, build applications with server-side languages ​​such as PHP, JavaScript, Ruby, Python, and Java.

It then searches, edits, and saves data with various database management tools such as MySQL, Oracle, MongoDB, PostgreSQL and sends it to the frontend.


As frontend developers, backend developers work with clients to meet their needs.


Back-end development tasks typically involve creating, integrating, and maintaining databases, creating server-side software using backend frameworks, creating and implementing content management systems, and working with web server technology and operating systems.


All this will become clearer after discussing the programming language, library, framework upfront. Needless to say, the backend developer is constantly engaged in testing and debugging the backend elements.

The work of a full-stack web developer

A full-stack developer is someone who can work on both the backend and the frontend. They are proficient in all the steps of the web development process, so they are adept at creating complete strategies and working out the details.


Full-stack developers usually have experience working in different roles at different stages of web development. So it is essential to have a prudence and foresight on their entire web development process.


They are proficient in working on various servers, networks, and hosting environments, including frontend and backend languages ​​and frameworks. They also have a good idea about business needs and user experience.

Mobile developer work


Web developers also specialize in mobile app development. In many cases, the websites that need to be accessed through the browser on the desktop, have a specific app on the mobile phone.

Android developers create apps compatible with Android devices. Java is the official programming language of Android. Many Android apps are now being built using the React (JJ) library and the React Native Framework.


IOS developers, on the other hand, are fluent in a programming language called Swift: Apple has created it individually for their apps. Also, some popular kits from mobile developers are Kaitlin, Flutter, or Xamarin.

Programming languages, libraries, and frameworks


The names of the languages, libraries, and frameworks that web developers have to work with to create a website or app have already been mentioned several times in our discussion. Let us know a little more about these.

What does programming language actually mean?

In the world of web development, language is the building block for creating websites, apps, or software. Just as a house is made of brick-stone-cement, so is a website made of different languages. Languages ​​required for web development can be divided into four categories – programming language, markup language, style sheet language, database language.


Programming language

A programming language is basically a set of instructions and commands that tell a computer to create a specific output.


High-level language

The language in which programmers write code is called high-level language. These are made up of a combination of understandable, logical words and symbols.


The way we talk to each other using Bengali words, programmers communicate with computers with this language. There are two types of high-level language – compiled or interpreted.


Compiled languages: C ++ and Java are compiled high-level languages. They are written and saved in a text-based format, which people can understand but not understand by computers.


The computer understands the source code by converting it into a low-level language, i.e., machine code, and produces the output accordingly. Compiled languages ​​are commonly used to create software applications.


Interpreted language: Interpreted language such as Perl or PHP code can be executed by reading the interpreter program. Interpreted language running scripts, for example, are used for content generation of a dynamic website. Python is also a very modern and dynamic interpreted language.


Low-level language


Some examples of low-level languages ​​are assembly or machine languages: they do not require any translation or interpretation.


Markup language

A markup language is used to specify the formatting of a text file. In other words, the markup language tells the software that is displaying the text what the design of the text will look like. This language consists of some small tags and some common words that people can understand.


The two most popular markup languages ​​are HTML and XML.

HyperText Markup Language (HTML)


HTML Full HyperText Markup Language. This language is used in website formatting. Inserting HTML tags into a plain text document determines how the web browser will display that document.


Source: Use website for writing.

  1. whoah this blog is excellent i love reading your posts. Keep up the great work! You know, many people are searching around for this info, you can aid them greatly.

  2. One thing I want to say is before getting more laptop memory, check out the machine within which it could well be installed. If your machine is usually running Windows XP, for instance, the memory limit is 3.25GB. Adding greater than this would just constitute a new waste. Make sure one’s motherboard can handle the upgrade volume, as well. Good blog post.

  3. I would also like to add that in case you do not currently have an insurance policy otherwise you do not belong to any group insurance, you may well reap the benefits of seeking aid from a health insurance agent. Self-employed or people with medical conditions ordinarily seek the help of the health insurance brokerage. Thanks for your article.

  4. you are in reality a just right webmaster. The website loading velocity is amazing. It kind of feels that you are doing any unique trick. In addition, The contents are masterwork. you’ve performed a fantastic task on this topic!
