What is coding and what is it used for? [VIDEO]

The definition of coding is the process of creating instructions for computers using programming languages. Computer code is used to program the websites, apps, and other technologies we interact with every day.

If you pay any attention to technology, you have undoubtedly heard the terms coding and programming dozens of times. Many of the best engineering careers require the ability to code.

If you want to work in a high paying industry such as software engineering, web development or data science, understanding and using code is essential. But what is it and why is it important?

Coding Definition

Computer coding is the use of computer programming languages ​​to give computers and machines a set of instructions about what actions to perform. This is how people communicate with machines. It is what allows us to create computer software such as programs, operating systems and mobile apps.

What is computer code used for?

Simply put, encryption is used to communicate with computers. Humans use coding to instruct computers and other machines on what actions to perform. We also use it to program the websites, apps and other technologies we interact with every day.

This brings us to the next question: how does coding work?

Coding 101: How does coding work?

Coding is simply telling a computer to flip some switches very quickly.

Computers are electronic machines made with transistors. Transistors are simple solid-state on and off switches. If you combine tens of thousands of these on/off switches, you get a computer.

It’s a little more complicated than that, but for the sake of brevity, we won’t delve deeper into the subject. Binary code (the ones and zeros you see in the movies) instructs these switches whether to turn them on (1) or off (0). Each transistor gets a 1 or a 0, and with thousands working at once, you can do some math.

Unfortunately, it would take an incredible amount of time to run an entire computer by manually typing a number for each transistor. That’s why we’ve developed high-level languages ​​to speed up the process. Rather than tackling individual transistors with machine code, we’re tackling entire sections of them to perform a specific task.

programming languages

Programming languages ​​are simply a set of rules that define how code should be written. These rules bring machine language closer to human language. It’s easy to think of it as a language the computer can understand.

Programming languages ​​are used to create web pages and applications. There are many languages ​​used in programming, including:

What makes a programming language unique?

Many programming languages ​​are relatively simple, but they do different things. For example, one of the most popular languages, JavaScript is mainly used for web pages and front-end development. On the other hand, Python is used for complete software programs as well as websites.

Whatever a software developer chooses is usually up to their discretion, as more than one programming language can often work for the same purpose.

Low Level Programming Languages ​​vs. High Level Programming Languages

There are many ways to classify programming languages. One of the most important classifications is the level of a language. Low level languages ​​are closer to binary code while high level languages ​​are closer to human language. Typically, learning to code is easier with a high-level language, while low-level languages ​​offer more freedom.

Computer programs

Computer programmers use different programming languages ​​to create software programs. A program is a text file that serves as a manual for a computer. When you start an application, you tell the computer to read the text file and run the commands in it. We use these programs to solve problems, among other things.

Depending on the computing power of the computer, a system can scan an enormous amount of instructions and follow them with astonishing speed. A human cannot possibly read thousands of lines of code and discern which steps to take as fast as a computer.

Where is encryption used?

While computer science deals with high-level theoretical ideas, almost every aspect of modern life relies on coding. Any application on a phone, tablet or computer uses computer languages ​​to run.

Other digital systems such as smart TVs and calculators also use it. Just about every new car uses it to control everything from air conditioning systems to fuel injectors. Cities use computers to control traffic lights.

Systems that used to be analog are now being streamlined using automated systems. This allows engineers to build a more efficient and cheaper system, structure and machine. Furthermore, some of the most advanced technical areas (such as artificial intelligence and machine learning) use encryption.

Computer code is everywhere

The rapid technological advancements we’ve seen over the past few decades have a far-reaching effect on how everything works. You have to look below the surface to see where the major changes have taken place. Computers replaced millions of working hours and warehouses of analog machines with faster, more secure, and more reliable systems.

Since computers run on code, it’s obvious why you can find it everywhere. Computers will continue to replace outdated technology in everything from microwave ovens to power plants. And the presence of code in our daily lives will increase.

How do you learn to code?

Today, your options for learning to code are virtually limitless. According to the United States Bureau of Labor Statistics, a majority of computer programmers have bachelor’s degrees. However, some employers are open to hiring programmers with a different degree or proficiency in specific programming languages.

Websites that teach programming

You can pick up programming skills from websites like Treehouse, for example. Or maybe you prefer text-based lessons, such as those from W3Schools.

Learn to code through apps

There are also plenty of mobile apps that let you practice your programming skills and take classes wherever you are. Some of the most popular coding apps include the following:

  • Enkic

  • Codehub

  • programming hub

  • Grasshopper

  • encoding

  • programming hero

Coding Boot Camps

Another great option if you’re serious about learning programming is a coding bootcamp. A boot camp is a short-term program with a curriculum designed around practical applications. You will find expert tutors and tutors and plenty of opportunities to practice your new skills. Some of the best coding bootcamps include the following:

Encryption FAQ

Is there a difference between coding and programming?

While the two are often used interchangeably, there’s more to it than a difference in terminology. The difference is often in the scope. While programmers are only concerned with writing code for software development, programmers are concerned with the bigger picture. For a more in-depth discussion, see our guide.

Is coding hard to learn?

New. Coding is everywhere and also learning materials for it. This has made it extremely easy to learn to code. On average, you would only need four to six months to learn programming languages. This is usually possible by attending coding boot camps that provide a short but intensive training.

Which code languages ​​are easiest to learn?

If you are a beginner, you may want to start with the top 3 easiest languages ​​to learn. These are HTML, CSS and JavaScript.

How much do coders earn?

The five most common jobs you would come across as a programmer are computer programming, full-stack development, data science, software engineering, and web development. The median hourly wages for these roles range from $20 to $40, with computer programmers being the highest paid.
