Do you know “programming”? This word is often heard these days, but it refers to writing instructions for operating various systems and computers, and it is actually used in a variety of situations in modern daily life. Furthermore, programming is now a compulsory class in elementary schools, which is the educational setting, and it will become used as a more familiar skill. Therefore, unless we deepen our understanding, we will be left behind in this ever-evolving era.
In this article, we will explain the overview of programming, why it is so popular, what you can do with programming, and the benefits you can acquire. It is not a skill that you must acquire, but I think that deepening your understanding and acquiring a few skills will help you cope with the future.
What is programming?
If you are familiar with the web or work in AI-related work, many people may have heard of it, but many may think, “I know the words, but it’s difficult to explain.” I don’t know. First, I will explain the meaning and overview.
writing instructions for running a computer
Programming is the process of writing instructions to run a computer. The word “program” has meanings such as “plan,” “schedule,” and “procedure,” and in web-related terms, it is used to refer to specific instructions given to a computer. Programming is the process of writing instructions.
Computers cannot think and act on their own. However, I can say that I am good at accurately carrying out instructions. Therefore, in order to produce the expected results, it is necessary to follow the correct instructions. Programming can be used for this purpose. By explaining each movement in order to achieve a goal and issuing instructions in a special language called a “programming language,” the computer will be able to move according to the instructions.
Humans can make predictions and take action, but computers do not have the power to imagine. It is necessary to strictly instruct a series of movements in a language that can be read.
history of programming
Programming is now widespread throughout the world, and it is no exaggeration to say that our lives are dependent on computers and various programs.
Until computers appeared and were able to take over the role of humans, we had to think about how accurately humans could perform calculations, how efficiently we could check data, and so on. I was thinking about how much I could increase my power. However, there were limits to human power, and there were limits to the problems that could be solved.
However, with the development of computers, this limit changed dramatically. For example, in the past, calculators were very large and difficult for ordinary people to use on a daily basis. However, in the 1970s, Intel, an American semiconductor company, developed a microprocessor, a device with a miniaturized circuit that performs calculations, and the miniaturization of computers rapidly progressed. Later, in the 1980s, personal computers became widespread, and there were no barriers to owning one.
Then, from the 1990s onwards, notebook computers were born and became even smaller and lighter. Along with this major development, the Internet has become explosively popular. Since 2010, with the development of smartphones and other devices, the use of technology has progressed even further.
In this way, we have come to live in a world where various devices have become widespread and are interconnected through the Internet. Nowadays, this technology is useful in a variety of situations, such as making payments and shopping with a smartphone, and using various sites and apps to enrich your life.
Computers, the connected Internet, and advanced programming make our comfortable lives possible.
Three reasons why it is popular
Programming is used in a variety of situations and the technology has become widespread, but there is a big reason why it has become so popular. Here we will explain three reasons why it is so popular.
Development of IT technology
With the development of IT technology, IT services that use programming are now appearing. IT is used in a variety of places, including things we use in our daily lives, products we use, and IT systems in business.
For example, the smartphone that we use on a daily basis is one of the most representative devices. A smartphone is a device that is operated by a program built into it. The reason why we can enrich our lives with smartphones, such as being able to make payments and shop with just one smartphone, and use SNS and apps, is because they have built-in smartphone programs. Masu. The spread of programming is a major factor in bringing IT closer to everyday life and business.
Creation of new industries
As programming has been developed, new industries have been born that take advantage of it. For example, the development of IoT is rapidly progressing.
IoT is an acronym that stands for “Internet of Things.” “Things” refers to all kinds of things, such as cars, machines, and home appliances, and refers to the connection of these things to the Internet. By connecting various things to the Internet, we can use them very conveniently, but programs are essential for this network communication.
The development of programming has led to the birth of new industries like this, but it is predicted that the demand for IoT and other technologies will further increase in our lives and business in the future.
Smooth collection and sharing of information
Advances in network communication technology have made it easier to gather and share information. Network communication is convenient because it allows you to easily exchange data with distant computers and to communicate quickly. However, it can also be said that programming supports this network communication technology.
Due to the impact of the new coronavirus and work style reforms, diverse work styles such as telework are becoming more widespread. When considering the creation of a comfortable work environment for employees and work-life balance, it is important for companies to respond to diverse work styles. What is extremely important in this telework is internal communication and information sharing over network communications. Everything that used to be done face-to-face now has to be done over a network.
However, various communication tools, online meeting tools, information sharing systems, etc. have become widespread, and information can be shared very smoothly. It can be said that the spread of these technologies is due to the support of programming technology.
Types of programming languages
By explaining each movement in order using various programming languages, the computer will be able to move according to instructions, but just as there are multiple languages we use, there are many different programming languages. There is. There are over 200 types, including minor ones. Here we will explain some types of languages.
Java
Java is often used in large projects and is the language with the highest market share in the world. Because it is platform independent and highly versatile, it is used in a wide range of fields such as Android applications, games, business systems, and embedded systems.
However, on the other hand, it requires a large amount of programming, making it difficult for inexperienced users to learn it for the first time. However, it has a high market share worldwide, so by learning it, you will be able to work on a wide range of projects.
C language
The C language is a language with a long history and is said to be the basis of many programming languages. It is used in a wide range of fields due to its fast processing speed and high versatility. Even today, it is used in all fields including software, core systems, and embedded systems. Demand is likely to continue to rise in the future as it is also used in IoT (Internet of Things) and home appliances such as “smart home appliances.”
C++
C++ is a language that incorporates object orientation into the C language. Object-oriented is a method of expressing objects as if they are being assembled and instructing a computer to operate, and object-oriented is currently the mainstream. C++ is one of the fastest processing languages, and is often used in situations where high-speed calculations are required.
The C language is originally a little difficult to learn, but with the addition of object-oriented ideas to the C language, it has become even more difficult. However, C++ is also sometimes used in large projects, so demand is expected to grow in the future.
C#
C# is a language developed by Microsoft. C++ has been further improved to become a more object-oriented language. It is used for smartphone and web application development, but it is also used in the game development tool “Unity” and is increasingly used for game production. It is also expected to be applied to advanced technologies such as robots and AI, making it a promising language.
JavaScript
JavaScript is a language primarily used to create web pages, and is used to control the visual appearance of web pages and communicate with servers. Because it is a language that runs on a browser, it is often used when creating dynamic web pages, and it can be said to be a promising language in recent years as the demand for web pages has increased due to the spread of smartphones.
We can also create web applications and browser games. It is a simple language and relatively easy to learn, so it is recommended for beginners.
PHP
PHP is a web-specific language often used for web applications and dynamic web pages. Since it is possible to create a dynamic mechanism that changes the displayed content depending on the user’s operating situation, it is possible to flexibly generate content that meets the user’s requests. It is widely used in Japan, so if you can learn PHP, you will be able to get a wide range of jobs. “WordPress”, the CMS used to create websites, is also composed of this language, so if you learn it, you may be able to be involved in various productions.
HTML
HTML is used to construct web pages. Strictly speaking, HTML is not a programming language, but a markup language. A markup language is a language that marks text such as website text so that it can be recognized by computers. By describing the meaning of a sentence using elements called “tags” and decorating it, you can issue instructions in a way that computers can understand. HTML is the language used to structure pages and is used by most websites on the Internet. It is a language that is relatively easy to learn, even for beginners.
CSS
CSS is a language used to set the design of web pages. Strictly speaking, CSS is not a programming language, but a style sheet language. A style sheet language is used to specify the style of a web page, and it is possible to define attributes such as the display format of structured documents, text color, font type, background color, layout, etc. Masu. Similar to the HTML explained earlier, it configures a website, but it is possible to specify the display format of a document structured in HTML using CSS.
Python
Python is a server-side language that specializes in web application development, data analysis, AI development, etc. Because the code is simple and easy to read and write, it is widely popular among beginners and veteran engineers.
Especially in recent years, the development of AI has been attracting attention worldwide, and Python is also attracting attention because it is an essential technology in the AI field. Investment in AI is expected to continue to increase, making it a promising language.
GO
GO is a language developed by Google. It was originally developed for internal use at Google, but is now used as an open source language. Although it has a simple syntax that eliminates error-prone elements as much as possible, it is highly secure and can be used safely. Although it is still a young language, the number of companies adopting it is increasing, so demand will likely increase in the future.
Kotlin
Kotlin is a language developed by Android official. It can be used interchangeably with Java, and source code created in Java can be called. It also requires relatively little code to implement and has features that prevent common errors. Kotlin, which has a high affinity with Java, which has a high market share, can be expected to see an increase in demand in the future.
Swift
Swift is a language developed by Apple. Basically, it is often used to develop services for Mac, iPad, and iPhone. Although the syntax is simpler than the language used for iOS development until Swift was introduced, it is still a developing language and is updated frequently. Although it is still a young language and the market in which Swift is used is not large, it is likely that demand for iPhone apps will increase in the future, so it is a language with great expectations.
Processing that programming is good at
Computers that receive accurate instructions have high processing power and can perform a variety of processes while maintaining a certain level of quality. We can say that we are mainly good at the following processing.
automatic processing
Automated processing refers to the ability to automate simple tasks by issuing instructions. A good example is a cleaning robot that cleans automatically. The built-in sensor detects dirt and dust and cleans it, automatically avoids obstacles, and moves automatically while collecting information with the sensor. In addition, automatic processing is used everywhere, making our lives and work more convenient.
high speed processing
High-speed processing refers to processing data instantaneously, many times faster than humans, by issuing instructions. Although humans can process data and perform calculations at a certain speed, there is a limit to that speed. A computer that receives instructions can process data and perform calculations tens of thousands of times faster. If data is processed automatically and at high speed, we won’t have to do it ourselves, so we can use our time more efficiently or focus on other things, improving efficiency in various ways. It is possible.
Accurate processing
Accurate processing refers to issuing instructions and processing exactly as instructed. Computers can only act according to instructions, so it is difficult for them to act flexibly or flexibly, but they are very good at automatically and accurately doing what they are instructed to do. Also, you won’t make any mistakes. Since you can always do what you are instructed to do without making any mistakes, it means that you can always perform actions with 100 points without making mistakes.
What you can do with programming
Mastering programming, which has become extremely popular in recent years, will lead to increased convenience in daily life and business, and will give you the opportunity to take action that you have never done before. From here, I will explain what you can actually do by mastering programming.
Website production
All websites you see on the Internet are created using programs. In addition to simply displaying a website on a computer or smartphone screen, it also controls the actions we take when viewing a website, such as playing a video or clicking a button to move to another page. It can be said that thanks to programming, it is possible to generate a corresponding reaction. If you learn languages such as HTML, CSS, and JavaScript, which are often used when creating websites, you will be able to create any website.
AI development
AI, which is artificial intelligence, is a robot that is programmed to make decisions and act according to the situation. It is possible to analyze and learn regularities from data, attempt to predict the problems presented, and derive solutions and optimal solutions. When you hear the word robot, many people may think, “I don’t have an image of it because it’s not familiar to me,” but the voice recognition service “Siri” installed in the iPhone and the artificial intelligence chatbot “ChatGPT” are also AI-based. is being utilized. It is already being used in many places around us, and it is likely that it will gain even more attention in the future.
App development
It is also possible to develop various applications. It can be said that programming is responsible for the complex operation of the various apps that run on smartphones, such as games, SNS, maps, and calendars. Nowadays, there are very few people who do not have smartphones or computers, and most people use them. As long as there is demand for smartphones and computers, it is likely that the number of installed apps will continue to increase.
Business system development
It is also possible to create business systems to automate and streamline specific tasks. In companies, it is extremely important to automate tasks that anyone can do, or to make tasks that would take time to do manually faster, in order to improve business productivity. . In fact, in recent years, it is not uncommon for companies to introduce systems such as attendance management systems and production management systems to improve operational efficiency.
data analysis
Analyzing acquired data is an important point in business, and programming can be used to efficiently analyze data. As mentioned above, it is good at automatic processing, high-speed processing, and accurate processing, so even with large amounts of data, it is possible to quickly analyze the characteristics that can be read from the data and future predictions. If it were done by humans, it would take a huge amount of time and there is a risk of making small mistakes, but if you use a program, you can do it accurately and quickly.
4 benefits of learning programming
As society becomes more IT-based, the number of people learning programming is increasing. There are many benefits to acquiring it as a skill, but I will explain four typical benefits.
High demand and promising future
In modern times, the use of IT in society is progressing, and it is predicted that this will continue to progress in the future. As a result, the demand for IT personnel is increasing rapidly. However, there is currently a shortage of human resources, and even though IT demand is expected to expand further in the future, Japan’s population and working population are decreasing, so the shortage of human resources is likely to worsen. Sho.
The lack of human resources is not just a problem faced by Japan, but is a global issue. The demand for and value of skilled talent is expected to continue to rise around the world. There are many products and services that utilize programming, not only in IT but in all industries, so by learning this, you will be able to become in demand in the future.
Able to respond to the further development of IT
The use of IT in society is progressing rapidly, and the technology is being used everywhere. Knowledge of IT will become essential to living in society in the future, and if you don’t acquire any knowledge, you will be left behind. By learning programming, you will be able to respond to a society that will further develop in the future, and you will be able to quickly respond to new technologies that will appear in the future. In order to make the future easier, we need to acquire knowledge and skills.
Business improvements can be made.
By using programming, it is possible to automate tasks that anyone can do, and to make tasks that would take time to do manually faster, so it is an opportunity for companies to improve their operations. It will be. Improving operations can have a positive impact in many ways, such as improving the working environment and increasing employee productivity.
Acquire the ability to think logically
Programs must be built in the correct order to give instructions and make the computer work correctly. Therefore, if an error occurs, you will have to continue to think about the cause and take other countermeasures, but by going through this process you will acquire the ability to think logically. This logical thinking ability is a power that can be used in daily life and work. Learning programming not only allows you to acquire skills, but also allows you to develop the skills you need in life.
summary
