  1. the information itself is stored in a DB
    2.write secure and reliable code for running the backend, make sure there is enough troughput, that the backend is reachable by the frontend,…
  2. all the components of your backend infrastructure, server, db, OS,…
  3. LAMP
  4. NodeJS enables the usage of javascriptprogramming on the backend. So the frontend developer who already is used to javascript can reuse this knowledge to learn backend programming

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

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

  • Set up database
  • Write server side code
  • Optimize server side code is able to handle high traffic
  • Debug and secure server side
    *Deploy code online so other people may use

  1. What is a technology stack?
    A technology stack is a combination of different languages, frameworks, and tools that developers use in order to build an app. These tools are stacked on top of eachother and are made to work together.

  2. Name a popular backend stack.
    A popular back-end stack is LAMP: Linux, Apache, MySQL & PHP. Linux is the operating system, Apache is the web server, MySQL is the database and PHP is the scripting language.

  3. Why is NodeJS convenient for front-end developers who want to start programming backend?
    It provides a server-side framework using JS. Now there’s no need to learn another language if you already know JS.

1 usually through a database.
2 check security and vulnerabilities,ensuring the code can handle large volumes of traffic,deploy the code online,write code server-side and code that interact with the database.
3 a stack is a bundle of components used to manage everything (LAMP= Linux,Apache,MySQL,PHP)
4 Flask,Django
5 because with only 1 code we can manage front+back end.

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

  2. Backend developers may need to do the following:

  • 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 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 set of classic backend technologies (e.g. LAMP, which is an abbreviation of Linux (operating system OS), Apache (server), MySQL (database), PHP (server-side language).

  2. NodeJS, a JavaScript server-side framework built on Chrome V8 engine and written in C++.

  3. Since JavaScript is often used for the client side (front-end) development, using NodeJS would simplify the entry barrier for such front-end developers because the same language can be used over the entire application and its development.

In the server.

Writing server side code
writing code to interact with a database
deploying code online so that others can use the resource
optimizing and handling large volumes of traffic
keep code security and vulnerabilities under check

A collection of different combinations of programming languages, tools, and components to build a software application

The classical set of backend technologies called LAMP, Linux Apache MySQL PHP

Since Jave is used in frontend the programmers are initially familiar with the tool making it easy to adapt to backend.

  1. How does a backend application normally store information?
    It stores it on a server/database

  2. Name a few things backend developers need to do.
    They have to make sure that the software runs on the server. So program everything secure and without any vulnerabilities. Also, they need to make sure that the interaction with the clients works (deploy it online)

  3. What is a technology stack?
    It consists of operating system, database, server, programming language

  4. Name a popular backend stack.
    LAMP. Linux, Apache, MySQL, PHP

  5. Why is NodeJS convenient for front-end developers who want to start programming backend?
    Because in this case you can use JavaScript as the programming language on the frontend and backend. Two flies with one stone!

  1. How does a backend application normally store information?
    In a db

  2. Name a few things backend developers need to do.
    Set up the db, writing server-side code, ensuring the server side code is secure and able to handle heavy traffic loads, integrating API’s, documentation, debugging.

  3. What is a technology stack?
    A set of tools that are integrated to create a web app, made up of an OS, server, DB and server-side language.

  4. Name a popular backend stack.
    LAMP

  5. Why is NodeJS convenient for front-end developers who want to start programming backend?
    JS is used on the front end and with NodeJS, they essentially use the same language on the back end so access is very easy.

  1. How does a backend application normally store information?
    The backend application communicate with the fontend via the server, this one receive requests and send a response using a handler functions.Requests received by the server to store informations are transfered to the backend app that store data in trhe database.
    The server receive the request–> Transfer the request to app–> App store data in database

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

  • Understand the server
  • Learn about database
  • Understand about HTTP
  • Understand about API

  1. What is a technology stack?
    Is the server pack that will handel the frontend request and backend, usualy is composed from (Operating system should be a server version(Linuxserver Or Windows server), a webserver (Exp. Apache, Tomcat, Nginnx…), Database (Exp: MySql, MariaDB…), and a programming language for the frontend that will communicate with the backend (exp PHP, Django…)

  2. Name a popular backend stack.
    LAMP is the most popular Backend stack

  3. Why is NodeJS convenient for front-end developers who want to start programming backend?
    Because they are used to the JavaScript in the frondend development, will make it easy for them to continue with the same programming language in the backend. 1 Language is used and learned

  1. in a database, for example MySQL

  2. Backend-dev work examples:

  • Write server-side code using one of the languages seen in the article before (php, python, javascript,…)
    Interact with a database (knowing for example how to make queries to the db, how to write into it etc.)
  • ensuring the code produced is:
    a) secure, testing for possible bugs/vulnerabilities
    b) does work also in high-traffic situations (e.g. Amazon on black friday)

  1. a technology stack is a kind of “bundle” needed to run the backend of an application.

  2. The author mentioned the example “LAMP” which stands for Linux, Apache, MySQL and PHP. Hence, the complete package including server, OS, database and programming language. There are of course lots of other stacks, but LAMP is the classic one.

  3. A front-end dev should already know JavaScript, so he/she doesn’t need to learn a new language: NodeJS is a JavaScript server-side framework.

  2. A few things developers need to do are; a) write server-side code, b) write code to interact with a database, c) ensure the server-side code is secure and free from vulnerabilities, d) ensure the server-side code is optimised enough to handle large volumes of traffic, and e) deploy the code online so people can use the service.

  4. A popular back end stack is LAMP - Linux, Apache, MySQL and PHP.

  5. NodeJS is convenient for front end developers who want to start programming back end because they don’t have to learn a new programming language, as the server understands NodeJS.
