Electronic devices like cell phones, laptops, and tablets require code to function properly. Coding allows humans to communicate with these devices. Modern technology such as traffic lights, calculators, smart TVs, and cars use internal coding systems.
Since computers do not communicate like humans, coding acts as a translator. Code converts human input into numerical sequences that computers understand. Once computers receive these messages, they complete assigned tasks such as changing font colors or centering an image.
Read on to learn about how people use code to communicate with computers and develop electronic devices, machines, and other technologies.
How Does Coding Work?
Computer programming languages, developed through a series of numerical or alphabetic codes, instruct machines to complete specific actions. Computer coding functions much like a manual.
A programmer or developer writes instructions describing the information and tasks needed to create a visual or to perform a task. Computers scan extensive coded manuals very quickly, executing the tasks that create and run a successful website or application. Displaying an image or section of text, changing font styles, and opening emails all require instructions included in the coded manual.
Users interact with websites and apps with the help of these coded instructions. The code itself does not show up on the screen. Instead, people see the words and images a developer or programmer asks the computer to display.
Coding tells a machine which actions to perform and how to complete tasks. Programming languages provide the rules for building websites, apps, and other computer-based technologies. Each programming language helps humans accurately communicate with machines.
Types of Programming Languages
Binary code comprises a series of zeros and ones, used to communicate instructions. This code is a low-level programming language. Each digit in a coded sequence connects to a switch in your computer. Each switch connects to an action, and together thousands of switches operate a device.
High-level code, a computer communication process that works much like human language, allows programmers to operate entire systems simultaneously. High-level programming languages convert human language from programmers into binary code that computers understand.
What Is Coding Used For?
Websites with user accounts, like Facebook, Instagram, or LinkedIn, require back-end developers to write computer code that connects websites to databases. Back-end developers often write code using languages such as SQL, Java, and Python.
Developers use other languages like Python, Objective-C, C#, Swift, or Ruby on Rails to create apps for cell phones and computer software.
Below, we list popular programming languages and their most common uses.
Used for developing software operating systems and databases
Used for building websites and software programs and performing data analysis
Used for creating the structures of a webpage, like paragraphs, links, and tables
Ruby on Rails:
Used for developing websites and applications and performing data analysis
Used for creating and developing games
Used for creating desktop applications and web services
Used for data engineering, data processing, and web development support
Used for text manipulation, web development, and network programming
Used for managing databases and creating dynamic webpages
Used for communicating with databases and managing and organizing data
Used for creating webpages and supporting front-end and back-end development
Used for creating apps, most commonly for Apple platforms
Used for writing software for Apple products
Learning How to Code
Coding requires critical thinking and creativity. Learning to code may prove a difficult computer science practice for some, but it can also be rewarding. Whether you want to create your own website or step into a computer science career, there are multiple options to learn coding skills.
- Coding bootcamps offer beginners and advanced learners short-term courses from expert teachers. Students receive regular practice opportunities to apply their new and developing knowledge.
