  1. A backend application stores information in a database.

  2. Some things backened developers do are: writing server-side code, writing code to interact with a database, ensuring that the server-side code is free of vulnerabilities, ensuring the server-side code is optimized for the expected volume of traffic, and deploying the code online so that other people can use the service.

  3. A technology stack is a set of backened technologies.

  4. A popular backend stack is called LAMP, which consists of Linux (OS), Apache (server), MySQL (database), PHP (server-side language).

  5. NodeJS is convenient because it uses the same language used in the frontend (JavaScript) .

  1. A backend application will normally store information on a server or database of some type.

  2. Backend developers with need to “write server-side code, write code to interact with a database, ensure that the server-side code is secure and free of vulnerabilities, ensure that the server-side code is optimized enough to handle large volumes of traffic, and deploy their code online so others can use the service.”

  3. A technology stack is a grouping of different back-end technologies.

  4. LAMP (Linux, Apache, MySQL, and PHP) is one such example of a stack. Django and NodeJS are other such examples.

  5. You have to only know one language for both the front-end and back-end of development. There is also a large amount of community support around JavaScript and NodeJS.

  1. Backend application stores informatiom in a database within a server.

  2. Protect and secure data, write code to interact with database, enable API s and write other code to interact with “dumb” clients

  3. A “Technology Stack” is all the compatable group of functioning elements required to operate a solution - built on top of each other - EG: Server, Operating System, Database, Server side Language

  4. LAMP is a popular backend stack. Linux - Apache - Mysql - Php

  5. Because they don’t have to learn a new language to do so.

1. How does a backend application normally store information?
The backend is a computation system that is, usually, separated from the application that operates the user experience; it can even be far away from the computer of the user in a server. As part of this core system, in the same server or in a different server, there usually is a separate subsystem where the data of the system is stored: it’s the database. All the information of a system is stored in the database.

2. Name a few things backend developers need to do.
A backend developer is in charge of the side where all the crucial and critical computations of the system – where those computations that constitute the core functionalities of the system – are stored and where they run. Therefore, this developer is in charge of the code of the server side, having to take care that the system does what it was built for. This includes many possible tasks as building / testing / maintaining the core logic of the system; building / testing / maintaining the databases; taking care of the connection between the logic side of the backend and its databases; ensuring the security of the backend and being sure there are no critical vulnerabilities; taking care of the capacity of the system to be efficient even in circumstances of high traffic; as well as others.

3. What is a technology stack?
A “technology stack” is a set of programming components where each exists separately and can be based on its own language and have its own rules of use, where also the whole set is available for developers to use together as one toolbox ideal for programming applications.

4. Name a popular backend stack.
One popular backend stack is LAMP: Linux (operating system), Apache (server that runs in the back), MySQL (database system manager), PHP (server-side language).

5. Why is NodeJS convenient for front-end developers who want to start programming backend?
NodeJS is a JavaScript runtime environment that executes JavaScript code in the backend, as opposed to most JavaScript code which traditionally ran only in the frontend. Since the NodeJS language is based on JavaScript, a language many frontend developers use, NodeJS turns into an ideal backend system to interact with, if seen from the perspective of a frontend coder. A frontend specialist can interact with the backend using the same language and many of the same tools used for the frontend thanks to NodeJS.

  1. A backend application normally stores information with a database. Databases are commonly used on the back-end of web applications. These databases provide an interface to save data in a persistent way to memory. A client might request information that is stored in the database, or a client might submit data with their request to be added to the database.

  2. A few things backend developers need to do are:

  • Writing server-side code
  • Writing code to interact with a database
  • Ensure that the server-side code is secure and free of vulnerabilities
  • Ensure that the server-side code is optimized enough to handle large volumes of traffic
  • Deploying the code online so that other people can use your service

  1. A technology stack is a name given to the classic set of backend technologies called LAMP. This acronym stands for Linux (operating system), Apache (server), MySQL (database), PHP (server-side language).

  2. Two popular backend stacks are Flask and NodeJS:

  • Flask is a popular backend framework written in Python. Django is the most well known and popular backend framework written in Python. Many developers start with Flask and move to Django after gaining experience.

  • NodeJS is a JavaScript server-side framework built on the Chrome V8 engine and written in C++. It is a very popular and powerful framework.

  1. NodeJS is convenient for front-end developers that want to start programming the backend of a web app because they can singularly use JavaScript coding language they are already familiar with from the client-side on the backend too.

    -Deploy the code online to help other users

  1. The information is stored into a centralized Database on the server

  2. Backend developers need to be able use the database an make it run smoothly

3+4. Technology stack is the usual tool box of the back en developer. Although it is changing rapidly its basics are: “LAMP” - Linux Operating System, Apache server, MySQL Database and PHP server-side language.

  1. NodeJS is convenient because it can be used in Javascript, and frontend also car be coded in Javascript which means its one less language to learn for devs. One language for both sides instead of two.

Question: what does a framework mean ? it shows up in the text but I don’t think it is being introduced/ defined anywhere ? @illyushin

3. What is a technology stack?

Quite close sir, but more likely to a set of backend technologies, meaning an “all-in-one tool box” for backend development. A combination of server, operating system, database and server side language or a framework which helps the different elements to communicate with each other.

4. Name a popular backend stack.

Not quite right sir, JavaScript is a programming language, the answer on your 3rd question is more likely to be one of the most known backend stack.

Hope this gives you a clear view of the subject, keep learning! :slight_smile:

If you have any doubt, please let us know so we can help you!
