What are the differences between IT, ICT, and IoT
IT, ICT, IoT… all of these are important words that describe the technology fields that support industry. Even if you have a rough understanding of what these terms mean, it can be difficult to explain the differences between them and how they relate to one another. In this article, we will introduce the meanings and differences between these words.

What is IT?
IT is an abbreviation for “Information Technology” and is a general term for technology that combines and utilizes communications such as the Internet with information devices such as computers.
The Internet began to spread to the general public after the release of Windows 95 in 1995. Between 1999 and 2000, ADSL and other broadband services for general individuals began to spread, mainly in urban areas.
The term “IT revolution” first appeared around 2000. Yoshiro Mori, who was the Prime Minister at the time, mentioned the “e-Strategy” in his policy speech in the Diet, which led to the enactment of the IT Basic Law and related bills. However, during the policy speech, Mori also mispronounced “IT” as “it.” “IT revolution” won the New Words and Buzzwords Award in 2000.
In 2006, the Policy” was launched, inheriting the ideas of the e-Initiative, with the aim of realizing a ubiquitous network society. FTTH using optical fiber also became common, ushering in an era of high-speed communications. In addition, the Ministry of Internal Affairs and Communications renamed its previous “IT Policy Principles” to the “ICT Policy Principles” in 2005. Around this time, the term ICT began to be used instead of IT.

ICT is almost synonymous with IT
ICT is an abbreviation for “Information and Communication Technology.” Overseas, ICT is more commonly used than IT.
Like IT, ICT is a broad term that can refer to not only the internet and computers, but also a wide range of digital technologies, services, and businesses, including smartphones, big data, social media, and smart speakers.
The difference between ICT and IT is that ICT tends to be used more to show how to utilize the Internet and computer-related technologies and to show future visions. Looking at how it is used in government agencies, the Ministry of Internal Affairs and Communications and the Ministry of Education, Culture, Sports, Science and Technology often use ICT, such as in “ICT Growth Strategy,” “ICT Regional Revitalization Award,” and “ICT Education,” while the Ministry of Economy, Trade and Industry often uses IT.

What is IoT?
IoT is an abbreviation for “Internet of Things.” It refers to a mechanism that enables things to be recognized, measured, and controlled remotely by connecting them to the Internet and exchanging information with each other.
Traditionally, the main things that could connect to the Internet were computers and mobile phones. Later, smartphones, game consoles, music players, and televisions also began to connect to the Internet.
As IoT becomes more commonplace in the future, the variety of connected things will explode in number, incomparable to today. Currently, IoT products that are beginning to spread include various electronic devices such as smart speakers, IoT home appliances such as lighting fixtures and air conditioners, and network cameras that can monitor pets while you are away. In addition
, vehicles and transportation such as cars, buses, and trains, sensors and cameras installed in retail stores, medical equipment in hospitals, production equipment and robots installed on production lines in factories, inspection machines in warehouses, agricultural robots and self-driving agricultural machinery that are active in farmland, agricultural drones, wearable devices worn by visitors in theme parks, etc. will be connected to networks and play important roles in various fields.

What is the difference between IoT and IoE?
There are two terms related to IoT.
The first is IoD (Internet of Digital). IoD refers to digital devices that are designed from the beginning to be connected to the Internet. Examples include computers, smartphones, and game consoles. Corporate mission-critical systems and servers are also types of IoD. The
second is IoH (Internet of Human). IoH means that people, like things, are connected to the Internet. In other words, it is a system in which humans communicate with and operate things via computers and digital devices.
And as a higher concept than IoT, IoD, and IoH, there is the term IoE (Internet of Everything), which means “the Internet of everything.”
IoE is the final stage of IoT. It refers to services and businesses that are premised on connecting not only things, but also people, processes, data, places, and everything else to the Internet, as well as the technologies that make this possible.
For example, let’s imagine a smart bed system in the medical field that can monitor the pulse rate, respiratory rate, and sleep/wake state of hospitalized patients. With IoT, it is possible to connect and manage the data obtained from this bed to a nurse call system or an electronic medical record database.
However, in a world where IoE is widespread, the types of data sent from beds will increase and the data connected to them will also become more diverse. This will create an environment in which treatment optimized according to changes in the patient’s condition is automatically performed. If the data obtained there is accumulated, it is expected that treatment methods will eventually evolve to the next stage.
IT, ICT, IoT, and IoE will continue to expand and impact every industry and field. In a few years, new services and business models that are completely different from those of today may be born. By understanding the differences between them and keeping a close eye on their trends, we may be able to see a vision of the future.

Exploring IoT: Industry-Specific Success Stories and Fascinating Use Cases
When you hear the word ” IoT ,” it may seem like something from a faraway world, but in reality, there are many things that have already permeated our daily lives. In order to understand the future of IoT, it is necessary to know in what fields IoT is currently being used. In this article, we will introduce what IoT technology can do and various examples of how IoT is used in businesses and homes.
We also explain the benefits and points to note when introducing IoT, so please read until the end.

Basic knowledge of IoT
Before introducing specific use cases of IoT, let’s first deepen our understanding of what IoT is.
What is IoT?
IoT is an acronym for “Internet of Things,” and is translated into Japanese as “Internet of Things.” In other words, it is a system that connects various things around us to the Internet.
Until recently, it was common to connect to the Internet from a computer at home or work. However, with the spread of mobile devices such as smartphones and tablets, it has become easier to access the Internet from anywhere. Furthermore, “smart home appliances” such as televisions and air conditioners that can be connected to the Internet are appearing one after another, making it possible to operate devices remotely even when you are far away.
There are great expectations for technology that utilizes IoT, as it has the potential to make life even more convenient and enrich society. Against this background, the IoT market continues to grow year by year, and is expected to further expand in the future.

How IoT works
Various home appliances and equipment targeted by IoT are equipped with sensors, cameras, etc. These sensors and cameras sense and collect information such as the condition of objects and the surrounding environment, and transmit this data to people and objects via the Internet. The sensors installed vary depending on the device, such as light sensors, temperature sensors, and acceleration sensors.
Let’s take smartwatches as an easy-to-understand example. A smartwatch acquires information such as biometric data such as heart rate and blood pressure, as well as the number of steps taken, based on sensors attached to the watch and GPS. That data is then sent to your smartphone via the internet or stored in the cloud, where it accumulates. The data collected in this way is analyzed by AI, converted into easy-to-understand information such as graphs, and then presented to the user again.
Until now, when selling something, the functionality and price of the item itself were considered to be the main sales criteria to determine whether it would sell or not. However, by introducing IoT, manufacturers are now able to add new added value to existing products.

What can be achieved with IoT technology
By using IoT technology, you can do four main things.
The keyword for what can be done with IoT is “remote”.

Know the issues to consider when introducing IoT
Although we have introduced the benefits of using IoT, there are also issues to consider when implementing it.
We will explain the five issues in an easy-to-understand manner.

Radio wave trouble
Radio wave troubles are an issue when introducing IoT.
Communication may become unstable due to radio wave interference, external noise, radio wave shielding, etc.
Radio wave problems may be resolved by taking measures such as selecting an appropriate installation location, setting the frequency band, and selecting the antenna.
It is also an effective method to obtain support from engineers who have technical knowledge about IoT device communication specifications and radio wave troubles.

Power supply trouble
Power supply problems are a major issue when introducing IoT.
Since power needs to be constantly supplied, power supply problems can affect the entire IoT system.
- Problems where power is not supplied to IoT devices due to power outages due to earthquakes, disasters, etc.
- An issue where an abnormality occurs in the power supply circuit, causing IoT devices to malfunction.
To solve these problems, it is necessary to have a backup power supply, such as an uninterruptible power supply or battery.

Securing human resources familiar with IoT
One of the issues to consider when introducing IoT is securing knowledgeable human resources.
Implementing an IoT system requires a wide range of knowledge, including hardware, software, cloud, and data analysis.
However, depending on the industry, there is a limited number of experienced human resources available for IoT technology, so it may be difficult to secure human resources.

What is an IoT system? Explaining the basic configuration, development flow, examples, etc.
“I hear that IoT is popular, but I don’t know how it works.” “I don’t know how to proceed with IoT system development.”
If you are reading this article, you may have questions like the ones above. In this article, we will explain the configuration of the IoT system, what it can do, the development flow, and usage examples. We also introduce the “IoT System Technology Certification”, which is a test for those who want to learn about IoT systems, so please refer to it.

IoT and IoT systems
IoT (Internet of Things) is a technology in which devices and sensors communicate via the Internet to collect and share data. Smart home appliances that have been released for home use in recent years are also products that use IoT technology.
As the name suggests, an IoT system is a system that uses IoT technology. It is used not only in factories but also in vending machines and home appliances, and it is expected that collecting and analyzing data will make life more comfortable and make work more efficient.

IoT system components
The IoT system consists of the following elements:
- device
- network
- application
- storage
Device
Devices mainly refer to hardware such as actuators, temperature sensors, humidity sensors, cameras, and smart meters. The device’s role is to collect the following data.
- temperature
- humidity
- Whether there are humans or pets
- Power usage status
It is also possible to operate on “things”. For example, perform the following actions:
- make a sound
- Operate the remote control
- opening/closing the door
- Discharging food given to pets
Devices in IoT also have the role of connecting to the Internet and sending and receiving data.
Network
IoT systems require networks to send and receive data between devices and between devices and applications. The following are network technologies used in IoT systems.
- Wifi
- Bluetooth
- 3G, 4G, 5G
- M2M communication (device-to-device communication)
In order for a device to process the information it collects, it must send and receive data. The wireless and mobile networks mentioned above are the constituent elements of the data transmission and reception path in the IoT system.
Application
In IoT systems, applications are used to process and analyze data. It may be easier to understand if you think of them as being in charge of utilizing the collected data.
The application also has the role of issuing instructions to the device based on the analyzed information. In the case of an air conditioner IoT system, energy savings can be achieved by issuing an instruction such as “According to the data collected by the sensor, there is no one around at the moment, so let’s turn off the power.”
Storage
Storage is used as a place to store collected data. In many cases, cloud storage will be used. In IoT systems, the amount of data collected by devices increases as the usage time increases.
With more data, applications are likely to perform more effective analysis. However, there is no numerical value such as “the optimal amount of data is XX GB”, nor does it mean that more data is better. Therefore, data needs to be collected and stored for a while. By using storage with a large upper limit that can be collected, it is possible to accumulate and analyze the necessary data.
Background to the spread of IoT systems
It can be said that IoT systems have spread rapidly in recent years.
- Network acceleration
- Popularization of smaller devices
- Reducing manufacturing costs through the development of advanced technology
Network acceleration
One of the important factors behind the spread of IoT systems is the increase in network speed. Recently, high-speed and stable Internet connections have become widespread, and mobile communication technology continues to develop. These advances in network technology have enabled large numbers of devices to send and receive data simultaneously. By using a high-speed network, we are able to exchange information in real time with little communication delay.
As mentioned earlier, networks are essential for IoT systems. As network technology has evolved and data transmission and reception within IoT systems has become faster, convenience has improved. As a result, it is thought that the number of people who want to use IoT systems continues to increase.
Popularization of smaller devices
One of the reasons behind the spread of IoT systems is the spread of small and power-saving devices. Among the components of IoT systems, this is the development of devices.
Advances in industrial technology and science have made it possible to create small yet high-performance devices such as sensors and controllers. Small devices are more energy efficient than large devices, and have the advantage of being easier to use in household products. Advances in device miniaturization have made it possible to incorporate devices into a variety of products.
Even small devices can collect data in real time. It can be said that the progress made in achieving smaller size and higher performance of IoT devices is directly linked to the spread of IoT systems.
Manufacturing cost reduction through the development of advanced technology
The reason behind the spread of IoT systems is the decline in manufacturing costs due to the development of advanced technology. This is also a story about devices among the components of an IoT system. IoT devices have also become cheaper to manufacture due to advances in semiconductor technology, microprocessors, energy efficient device designs, and many other related technologies.
Furthermore, as an advanced technology, the application aspects of the components of IoT systems are also evolving. Advances in cloud computing and big data technology have also reduced the cost of data collection and processing.
The above two technologies have made it possible to manufacture high-performance IoT devices at low cost, and the convenience of the IoT system as a whole has improved, which is why IoT systems are becoming more popular.
What you can do with IoT systems
The following are examples of what can be done with IoT systems.
- Operations on things
- Monitoring the status and operation of things
- Communication between things
Operations on things
IoT systems allow users (humans) to operate things remotely.
For example, in a smart house, you can use your smartphone or tablet to adjust the temperature of your home’s air conditioner, turn on/off lights, and feed your pet. Smart cars also use mobile apps to unlock the car’s doors and start the engine.
By using IoT systems, it is possible to operate things via a network even when the user is not present.
Monitoring the status and operation of things
IoT systems can monitor the status and operation of things in real time. Devices such as sensors and actuators are embedded in products to collect and send data to applications and storage.
For example, a refrigerator with a built-in temperature sensor monitors the temperature inside the refrigerator and notifies the user if the temperature is abnormal. This not only allows users to notice abnormalities inside the refrigerator, but also helps prevent food from deteriorating if noticed early.
Let’s also consider the example of a smart meter installed as an electricity meter. Smart meters not only monitor electricity usage and notify the utility company, but also provide recommendations to users on how to improve their electricity usage based on the collected data and analysis results.
By monitoring the status and operation of things through IoT systems, it is possible to improve efficiency and safety, and discover problems early.
Communication between things
IoT systems allow things (products) to communicate with each other.
For example, in a smart home, sensors and smartphones communicate to share data and perform operations. In addition, in factories, manufacturing lines that use IoT systems allow machines to share data with each other. As a result, it will be possible to understand the details and progress of the preceding and succeeding processes, which will help improve operational efficiency and detect abnormalities.
The use of IoT systems allows things to communicate with each other, making life and work more efficient and convenient.

IoT system development flow
The general waterfall development flow for IoT systems is as follows.
- Requirements definition and design
- implementation
- quality test
- Release and maintenance operations
Requirements definition and design
Define requirements at the beginning of IoT system development. This is the process of clarifying the purpose and functionality of the system, working backwards from what users want, and understanding requirements and business needs.
Requirements definition clarifies what devices and sensors are needed, how data will be acquired and processed, network connectivity, security requirements, etc. In addition, the necessary budget, number of development team members, period, etc. are determined at the requirements definition stage.
Design is done after requirements definition. We provide technical details for the content documented in the requirements definition. Specific details include device architecture, data flow (network), user interface, etc.
Implementation
Once requirements definition and design are complete, implementation begins. We will actually create a pre-designed system as a program. The specific content to be implemented in an IoT system includes configuring devices and sensors, building network connections, and processing data. If you have any content that has been designed, such as cooperation with applications or cloud services, please implement it for those as well.
During implementation, we select an appropriate programming language and framework in advance, and optimize the programming itself from the standpoint of safety and performance.
Quality test
After the implementation is complete, we will conduct a quality test. Specific examples of quality tests include functional tests, performance tests, unit tests, and coordination tests.
Functional test: Check whether it can operate as required
Performance test: Evaluate whether it can withstand a certain load, communication speed, processing speed, etc.
Unit test: Check whether one function operates as expected
Linkage testing: Not only does it meet the specifications, but it also confirms that there are no abnormalities in areas where there were no problems in the unit test when multiple functions are combined.
If we determine that the quality does not meet the standards through quality testing, we will provide feedback to the design and implementation.
Release and maintenance operations
After passing the quality test, release your IoT system. At release, we will install and configure the system and create documentation for users.
After release, system maintenance and operation will begin. The goals of maintenance operations are to maintain system stability and performance, and improve user satisfaction. Specifically, we carry out periodic bug fixes and troubleshooting for the entire system.
It is also necessary to improve customer support. You may end up developing new features based on actual customer feedback.

Examples of IoT system introduction
We will introduce three examples of introducing IoT systems.
- Apartment that looks after seniors
- You can check the status of the trash can
Apartment that looks after seniors
Families who live far away from an elderly person often find it burdensome to visit them regularly to check on their condition. This condominium collects data on usage frequency and status by having customers use home appliances that incorporate an IoT system.
If an abnormality is detected in the data, a notification will be sent to the condominium management office, which will help prevent any accidents. By using the IoT system, we are contributing not only to families in need of nursing care, but also to the nursing care industry.

You can check the status of the trash can
Nippon Systemware has developed “BigBelly Solar,” a trash can that incorporates IoT. The collection status of garbage accumulated in the trash can is visualized, making garbage collection more efficient. It also has an automatic garbage compaction function, so you can check the accumulation status and have the advantage of preventing garbage from overflowing from the trash can.
By visualizing the collection status of each trash can, you will be able to see which trash cans are used more frequently and which ones are less frequently used, and you will be able to more efficiently consider areas where you should increase or decrease the number of trash cans.
This is an example that shows how using IoT devices can help solve familiar problems.
Sunstar has developed G・U・M PLAY, a device that works with a smartphone to record tooth brushing status. By incorporating a sensor into your toothbrush, you can score your tooth brushing based on the movement of your toothbrush and the time you brush.
Users can use a smartphone app to view the data collected by the toothbrush and understand how well they are brushing their teeth. The app analyzes your tooth brushing data and gives you advice on how to best brush your teeth.
This is an example of using an IoT system to visualize something that you cannot understand even if you do it yourself.
Introduction to IoT system certification
From here, we will explain the following two contents about the “IoT System Technology Certification Exam”, an exam that can check the development and knowledge of IoT systems.
- Overview of IoT System Certification and Benefits of Taking the Test
- Skills and knowledge gained through IoT system certification
Overview of IoT System Certification and Benefits of Taking the Test
