Web Development

Introduction

Web development is the process of designing and creating websites. It involves a wide range of tasks, including coding, designing, and building web applications, as well as creating and managing content for the websites. Web developers use a variety of programming languages, web frameworks, and other web technologies to create websites. They often work with web designers and other web professionals to ensure that the website is visually appealing, user-friendly, and easy to navigate.

Why is web development important?

Web development is important because it enables businesses to create an online presence. This presence can be used to reach a wider audience, increase customer engagement and loyalty, and generate more sales. It can also be used to create interactive content, such as forums and chatbots, to provide customers with a better experience. Additionally, web development can be used to develop web applications that can automate processes, increase efficiency, and provide a better customer experience.

What is a website?

A website is a collection of related webpages, images, videos or other digital assets that are hosted on a web server and made available to users on the Internet. Websites are typically accessed via a web browser and can contain text, images, audio, video, and other multimedia content.

How does the internet work?

The internet works by connecting computers and other devices around the world through a network of cables, satellites, and wireless signals. This network is known as the World Wide Web and it allows users to access and share information online. At the heart of the internet is a system of computers connected by a special type of software called a router. Routers allow data to travel between computers and servers, creating an interconnected web of information. When a user wants to access a website, the request is sent to a server, which then sends the requested data back to the user.

What does front-end mean?

Front-end refers to the client side of a website or application. It is the interface between the user and the technology. It consists of the visuals, design, and user experience that a user interacts with when they visit a website or use an application. It includes HTML, CSS, and JavaScript code.

HTML

HTML stands for Hypertext Markup Language. It is a coding language used to create webpages and other documents that can be displayed in a web browser.

CSS

CSS stands for Cascading Style Sheets. It is a coding language used to style the layout and design of a webpage or document. It is used to create a consistent look and feel across multiple webpages and documents.

JAVASCRIPT

Javascript is a scripting language used to create dynamic webpages and web applications. It is commonly used to add interactive elements to webpages, such as menus, forms, animations, and games.

What does back-end mean?

Back-end is a term used to refer to the part of a website, application, or service that is not visible to the user, but instead handles data storage, logic, and algorithms. It is the part of the system that interacts with the database, performs complex calculations, and processes user requests.

Backend Development Tools For Web Developers

Programming languages;

Programming languages are the languages used to create computer programs and applications. They are designed to communicate instructions to a computer or other device and are used to control the behavior of the device. Common programming languages include C, C++, Java, Python, and JavaScript.

EXAMPLE:

Python;

Python is a high-level, interpreted, interactive, object-oriented scripting language. It is a popular language for web development, data science and scripting. Python is a powerful language used for a wide variety of tasks. It has simple syntax and is easy to learn, making it a great choice for beginners. Python is fast, flexible, and powerful, and comes with a wide range of built-in libraries for data analysis and manipulation.

Frameworks;

Frameworks are pre-built collections of code that developers can use to quickly build applications or websites without having to build everything from scratch. Frameworks provide structures for organizing code, such as specific directory structures, pre-built modules, and libraries that can be used to quickly get an application or website up and running.

EXAMPLE:

Node.js ;

NOBE.JS is an open-source JavaScript library that enables developers to easily create cross-platform mobile applications. It offers an intuitive, highly modularized structure and allows developers to quickly and easily create mobile applications that are consistent with native mobile standards. NOBE.JS also offers many features such as a UI library, performance profiling, cloud storage and more.

Databases;

Databases are structured collections of data that are stored in a computer system. They are used to store and organize information, such as customer records, inventory, financial transactions, medical records, and more. Databases are used to create and manage data, provide access to stored data, and help ensure the accuracy of data.

EXAMPLE:

MongoDB;

MongoDB is a cross-platform, document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with schema. MongoDB is developed by MongoDB Inc. and is free and open-source, published under a combination of the GNU Affero General Public License and the Apache License.

Servers;

Server is a computer program or a device that provides functionality for other programs or devices, called “clients”. This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called “services”, such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

EXAMPLE:

Apache;

Apache is a web server software that is a popular choice for running websites and web applications. It is open-source, meaning it can be freely used, modified, and distributed. It is used to serve more than half of all web sites. Apache is highly configurable and can be used in conjunction with other software components such as databases, content management systems, and more.
