Programming is the process of writing instructions that computers execute, using languages such as Python, JavaScript, C++, Java, and SQL. Software development encompasses the full lifecycle of building applications — from design and coding to testing, deployment, and maintenance Read more
In web development, what does 'DOM' stand for?
HardDOM stands for Document Object Model. It is a programming interface for web documents (HTML and XML) that represents the page as a tree-like structure. This allows languages like JavaScript to "reach in" and change the content, style, or structure of a webpage dynamically.
Without the DOM, web pages would be static and boring-it's the reason a button can change color or a menu can pop up when you click it!
Which programming language is primarily used for Android apps?
MediumKotlin and Java are the primary programming languages used for developing Android apps. While Java was the original standard, Google officially announced Kotlin as the preferred language for Android development in 2019.
The first Android phone, the T-Mobile G1 (released in 2008), had a physical slide-out keyboard because the OS wasn't originally designed for touchscreens!
Which programming language is mainly used for statistical computing?
HardR is the programming language mainly used for statistical computing and data visualization. It is widely used among statisticians and data miners for developing statistical software and data analysis.
The name "R" comes from the first names of its two creators, Ross Ihaka and Robert Gentleman, and also as a play on the name of a previous statistical language called "S"!
Which language is primarily used for 'Unity' development?
MediumC# (C-Sharp) is the primary programming language used for development in the Unity game engine. Because C# is easy to learn but powerful, it has helped Unity become the most popular engine for indie game developers.
Unity used to support a version of JavaScript (called UnityScript) and a language called Boo, but they eventually removed them to focus entirely on C#!
Which programming language is often called the 'mother of all languages'?
HardC is often called the "mother of all languages" because many modern and popular languages, including C++, Java, PHP, and Python, are either built upon C or have borrowed heavily from its syntax and structure.
The Unix operating system was almost entirely rewritten in C in the early 1970s, which was a revolutionary move at the time because most OSs were written in difficult assembly code!
Which programming language is most used for Data Science?
MediumPython is the most widely used programming language for Data Science. Its popularity is due to its simple syntax and the vast ecosystem of libraries like Pandas, NumPy, and Scikit-learn that make data analysis and machine learning much easier.
Python wasn't actually named after the snake; the creator, Guido van Rossum, named it after the British comedy troupe "Monty Python"!
Which company created the 'Markdown' language?
HardMarkdown was created by John Gruber and Aaron Swartz in 2004. It is a "lightweight markup language" that allows you to write formatted text (like bold, italics, or lists) using simple characters like # and , which can then be converted to HTML.
This very explanation is likely being formatted using a version of Markdown!
Which database uses tables?
HardA Relational Database (RDBMS) is a type of database that stores and provides access to data points that are related to one another. It organizes data into "tables" consisting of rows and columns, where each row represents a unique record and each column represents a specific data field. SQL (Structured Query Language) is the standard language used to interact with these databases.
The idea for relational databases was first proposed by Edgar F. Codd in 1970 while he was working at IBM. Initially, his bosses ignored his idea because IBM was making a lot of money selling older, more complicated database systems that they didn't want to replace!
Which year was the World Wide Web introduced to the public?
HardTim Berners-Lee introduced the World Wide Web to the public in 1991. While the Internet (the underlying network) had existed since the 1960s, the "Web" made it accessible to everyone through browsers and links.
The very first website is still live today at info.cern.ch!
Which company created the 'Go' language?
MediumGoogle created the Go programming language (also known as Golang). Released in 2009, it was designed to be simple, efficient, and great for "concurrency" (running many tasks at the same time).
Go was created by computer science legends Robert Griesemer, Rob Pike, and Ken Thompson (who also co-created Unix and C)!
What does 'CSS' stand for?
MediumCSS stands for Cascading Style Sheets. It is a style sheet language used for describing the presentation (look and feel) of a document written in HTML. CSS handles things like colors, fonts, and layout.
By using CSS, web designers can change the entire look of a website just by editing one single file, without touching the HTML of the individual pages!
Which programming language is used for the logic of web pages?
EasyJavaScript is the programming language used for the logic and interactivity of web pages. While HTML structures the page and CSS styles it, JavaScript makes the page "do" things, like responding to button clicks or updating content without reloading.
Despite the name, JavaScript has nothing to do with the Java programming language; the name was chosen as a marketing tactic to ride on Java's popularity at the time!
Which language is often used for Data Science?
MediumPython is the language most often used for Data Science. Its dominance is due to its vast collection of specialized libraries like NumPy (for math), Pandas (for data manipulation), and Scikit-learn (for machine learning). Because Python reads almost like English, it allows scientists and analysts to focus on solving data problems rather than complex coding syntax.
Python's name actually comes from the British comedy group "Monty Python's Flying Circus," as the creator wanted a name that was short and slightly mysterious.
What is the name of the process of finding errors in code?
EasyDebugging is the process of finding, analyzing, and removing errors (bugs) within a computer program. It is a critical part of the software development lifecycle. The term gained popularity after Grace Hopper, a computer science pioneer, found a literal moth stuck in a relay of the Harvard Mark II computer in 1947.
That original "bug" is still preserved today at the Smithsonian Institution?s National Museum of American History!
Which programming language was created by Guido van Rossum?
MediumPython was created by Guido van Rossum and first released in 1991. Van Rossum's goal was to create a language that was as easy to read as plain English.
Because he was the final arbiter of all changes to the language for so long, Python users gave Guido the title of "Benevolent Dictator for Life" (BDFL) until he stepped down in 2018!
What was the first domain name ever registered?
Hardsymbolics.com was the first domain name ever registered, on March 15, 1985. It belonged to Symbolics Inc., a computer manufacturer.
Today, there are over 350 million registered domain names, but back in 1985, Symbolics was the only one in the world!
Which company developed the 'C#' language?
MediumMicrosoft developed the C# (C-Sharp) programming language, released in 2000. Led by Anders Hejlsberg, the goal was to create a modern, object-oriented language that would work seamlessly with Microsoft's .NET framework.
The name "C#" was inspired by musical notation, where a "sharp" (?) indicates a note should be higher in pitch; it implies that C# is an "incremented" or better version of the C++ language!
Which company created the 'Swift' programming language?
MediumApple Inc. created the Swift programming language. Released at the 2014 Worldwide Developers Conference (WWDC), it was built to be a modern replacement for Objective-C, offering better performance and safety features.
Swift is now an open-source language, meaning developers outside of Apple can contribute to its development and use it for things like server-side programming on Linux!
Which language is used in data science?
MediumPython is currently the most popular programming language used in the field of Data Science. It is favored by data scientists because it is easy to learn and has a massive collection of libraries (like Pandas, NumPy, and Scikit-Learn) that make it simple to clean data and build complex AI models.
Python was not named after the snake! Its creator, Guido van Rossum, was a big fan of the British comedy show "Monty Python's Flying Circus" and named the language after the comedy troupe to keep the project "fun" and "short."
What is the name of the world's first widely used web search engine?
HardArchie is considered the world's first widely used search engine, created in 1990 by Alan Emtage at McGill University. Before Google or even Yahoo!, Archie allowed users to search for files on FTP servers.
The name "Archie" is short for "archives" (without the 'v'), and it inspired the names of later search engines like Veronica and Jughead!
