  1. Backend applications normally store information through a database.
  2. Backend developers write the code to connect clients to servers, the functionalities of the application, and any complex code that is performed behind the scenes.
  3. A group of server-side applications. LAMP as an example (Linus, Apache, MySQL, and PHP). A stack means each layer of the application is built on top of another.
  4. NodeJS and Django are popular programming stacks.
  5. NodeJS is written in Javascript, which is one of the only languages used for both front-end and back-end. This allows front-end users to have access to back-end development without coding in a different language.

  1. A backend application normally stores information in a database.

  2. Backend developers need to be able to:

  • Write server-side code
  • Write code that enables interaction with a database
  • Ensure that server-side code is secure and vulnerability-free
  • Optimize server-side code to handle large traffic volumes
  • Deploy their code for others that are online to use

  1. A technology stack is a framework of programming languages used on the backend of an application.

  2. A classical example of a technology stack is LAMP:

  • Linux - an operating system
  • Apache - a server
  • MySQL - a database
  • PHP - a server-side language
  1. NodeJS is a server-side framework and is convenient for front-end developers who want to start programming backend, because it was born from JavaScript, a client-side (frontend) language. In this way, learning this one language allows a developer to program frontend as well as backend.

    Basically the set of backend technologies that are used

  2. Name a popular backend stack.
    LAMP

  3. Why is NodeJS convenient for front-end developers who want to start programming backend?

QNS 1. How does a backend application normally store information?
ANS: A backend application normally store information in a database.

QNS 2. Name a few things backend developers need to do.
ANS: They will need to do the following below.

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

QNS 3. What is a technology stack?
ANS: Technology stack is a programming framework for backend application development.

QNS 4. Name a popular backend stack.
ANS: A popular backend stack will be LAMP - where it stands for Linux (operating system), Apache (server), MySQL (database), PHP (server-side language).

QNS 5. Why is NodeJS convenient for front-end developers who want to start programming backend?
QNS: NodeJS is a server side framework as it was from JavaScript, which is a front end language In this way, we have a single language over the entire application and lead to having one language less to learn.

1: In a database.
2: Write server side code, set up databases, optimise code for scale, bugs and security.
3:A set of programming languages and frameworks used to build apps.
4: LAMP
5: Because its a smaller learning curve, it allows both front and back end to use the same language.

  1. How does a backend application normally store information?
    Data sits in a database running on a server
  2. Name a few things backend developers need to do.
    Devs need to understand servers, databases, APIs and HTTP
  3. What is a technology stack?
    A stack is series of hardware and software components that create a system
  4. Name a popular backend stack.
    Django for Python is popular as is NodeJS for JavaScrypt
  5. Why is NodeJS convenient for front-end developers who want to start programming backend?
    NodeJS is a Java based and Java is used for both frontend and backend. It should be easier to grasp and understand.

  1. How does a backend application normally store information?
    The backend normally stores information by a database usually using SQL or No SQL databases

  2. Name a few things backend developers need to do.

  • Write Server side code
    Write code to interact with database
    ensuring that server side code is optimized enough to handle large volumes of traffic

  1. What is a technology stack?
    technology stack is the combination of programming languages, tools and frameworks that developers use to create web and mobile applications

  2. Name a popular backend stack.
    Windows OS, Linux or apache

  3. Why is NodeJS convenient for front-end developers who want to start programming backend?
    It is convenient because rontend developers will be familiar with JavaScript. NodeJS runs on the JavaScript language making it easier to switch to backend without having to learn another coding language.

4. Name a popular backend stack.

Those are Operating System, and apache is a software for webserver, maybe you want to redesign your answer.

  1. How does a backend application normally store information?
    Usually in a database.

  2. Name a few things backend developers need to do.
    Write server side code, write code to interact with database, and make sure code is free of vulnerabilities
    .

  3. What is a technology stack?
    Classic set of backend technologies that are used.

  4. Name a popular backend stack.
    LAMP. Stands for Linux (operating system), Apache (server), MySQL (database), PHP (server-side language).

  5. Why is NodeJS convenient for front-end developers who want to start programming backend?
    Front-end developers already know the language.

  1. On a server in a database

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

  3. A technology is defined as the set of technologies an organization uses to build a web or mobile application. It is a combination of programming languages, frameworks, libraries, patterns, servers, UI/UX solutions, software, and tools used by its developers.

  4. JavaScript / Python / Django

  5. Because JS can be used both in frontend and backend developing. This way you have to learn one programming language less

  1. A database is normally used to store information for a backend application.

  2. Backend developers need to do–:

  • Write server-side code.
  • Ensure the code is secure and free of vulnerabilities.

  • Write code to interact with a database.
  • Deploy code online to be used by others.

  1. A technology stack is a backend technology which has an operating system (Linux), a server (Apache), a database (MySQL), and a server-side language (JS).

  2. Django is a popular backend stack.

  3. The use of JavaScript in NodeJS makes it convenient for frontend developers to pursue backend development. They can use the one language (JS) to do front and back end development, using the NodeJS framework.

Response:

  1. Backend apps store their info on servers/databases
  2. B.E. devs take care of writing the server-side code, code to interact w/ the database, audit the code to make sure it doesn’t contain bugs, make code available online for others to use.
  3. Tech Stack is the language and framework you’re using.
  4. Popular tech stack: LAMP (Linux, Apache, MySQL, PHP)
  5. The convenience of NodeJS for front-end devs is it carries to the back-end as well (same language) and therefore they don’t spend more time learning a new language to work on the b.e.
