IoT Explained: How it Works?

The term IoT, expanded as the Internet of Things, refers to the network of billions of physical devices around the globe that are connected to the internet and can collect and share data. The evolving devices with added digital intelligence are now capable of communicating without needing human involvement. In simpler terms, almost any device that can be connected to the internet can be converted into an IoT device. For instance, a light bulb that can be controlled through a smartphone is an IoT device. Similarly, a sensor, a streetlight, or a toy can be an IoT device.

To explain it further, the term IoT is used for devices that do not usually have an internet connection and with added connectivity feature, they are able to function without human intervention. This is why a PC is not considered an IoT device. This article explains the working of IoT.

IoT Working

An IoT system consists of four main components including sensors/devices, connectivity, data processing, and a user interface. Here is what these components do:

  1. Sensors/devices

The sensors or devices are responsible for gathering data from the environment and send it to the system for the processing. The term data here refers to anything ranging from the simple temperature reading to something as complex as a video. Different devices or sensors collect this data depending on what they are meant for. There can be more than one sensors too that form a part of a device. Therefore, anything that collects data of any kind from the environment comes under the category of sensors or devices for IoT.


  1. Connectivity

Once the data is gathered, it needs to be sent to the cloud. This is where connectivity is required. The devices/sensors are connected to the cloud using one or more of the methods, for example, Bluetooth, low-power wide-area networks (LPWAN), WiFi, satellite connection, a cellular network, or direct connection to the internet through Ethernet. The method to be used by the IoT device for connectivity is specific, however, the aim is to send the gathered data to the cloud.


  1. Data Processing

Once the data has been transferred to the cloud, it is processed there using software that is specially designed for this data. This function can be as simple as checking whether the temperature is in an acceptable range or as complex as identifying the objects in a video. After the processing, if the results are something important like temperature is not in acceptable range or the computer detects something objectionable in the video, it has to be sent to the user so that they can take some action. This is where the user interface is needed.


  1. User Interface

The end user is alerted with the important information through some user interface. This can be done by sending an alert message, email, or a notification to the user on their smartphone. It is also possible for the user to proactively check in on the system for any important information through an interface. User interfaces are, again, simple as well as complex depending on the type of device and urgency of information. There are interfaces that will allow you to just check the video, message, or notification while there some complex interfaces that have an added functionality of allowing the user to act on the information received and affect the system. For example, if the temperature of a cold storage goes higher than acceptable, a user might be able to control it from their smartphone.


With the continuous drop in the prices of smart devices, sensors, and communication, IoT is increasingly becoming cost-effective. More and more devices are adding to the list of IoT devices and consumers are getting the benefit of it. In the near future, our living and working places will have a huge number of smart products. Right now, the increase in IoT is a topic of hot debate. While some are happy to welcome the technology in their lives while others want their lives to go back to as simple as they were before the dawn of the internet. But, whatever may be the case, IoT is here to stay.

Cloud Computing and Its Benefits – Everything You Need to Know

Cloud Computing and Its Benefits – Everything You Need to Know

Cloud computing is increasingly gaining popularity and is in use since almost two decades now. It was not very well received in the beginning but now more and more businesses are embracing it. They are using the benefits of cloud computing to maximize their return on investment. While there are a few companies who have chosen full-scale overhaul, others have started testing the cloud services. The companies are recognizing the potential benefits of cloud computing and are increasingly using it to their advantages.

Benefits of cloud computing are numerous. However, below are five top advantages that you get from sourcing IT services in the cloud.

  1. Lower Expenditure

Cloud computing allows the businesses to source IT services on-demand. This means the businesses provide the services as and when they are required. The investment model of the businesses changes to the one based on operational expenditure. They don’t need to invest in large-scale capital projects with a limited lifespan, which requires a huge investment in servers and software licenses. When IT services are sourced in the cloud, it is the vendor who is responsible for the majority of the infrastructure. It is more convenient, both for businesses and consumers.

  1. Flexibility

Cloud services provide the employees with an advantage of working from anywhere in the world. They just need a system and internet connection to access all the important data, files, documents or tools. If they have enough bandwidth, they can work from any remote location. This allows them to escape office environment and work according to their comfort, which increases their productivity. A large number of services are being used by business employees across the world. These include a virtual private network server, emails, office applications, databases, CRM, video conferencing, and production systems. In fact, there is no end to the cloud computing services.

  1. Business Continuity

The mobility and flexibility of cloud computing lead to another major advantage which can be called continuity of business. This means that remote working capability provided by cloud makes sure that business keeps running even in the events of disaster or any damage to the office or infrastructure. In the events of fire, snow, floods, etc., the employees can work from wherever they are located. Therefore, even in disaster, there will be no effect on the productivity of the business. In the past, when there was any disaster, many of the businesses would suffer losses. This has been decreased to a great extent.

  1. Security

Opposite to what is generally believed, cloud computing provides improved IT security. When the concept was in its infancy, there were concerns over the security. However, with the time the technology has matured and with a better understanding of the concept, the fears are not there anymore. Rather, there are cases that cloud computing provides improved defenses. A lot of research and investment has been made to make the cloud computing safe and secure. At present, cloud computing offers highly secure IT services, which keep the consumer data safe.

  1. Easier Maintenance

Lastly, cloud computing services are easier to maintain and upgrade. Since cloud computing service provider is responsible for server, software, and network management, the IT professionals in the office can work to achieve the goals of the organization. They need not put in efforts all day long to keep the systems working fine. There are dedicated experts working with the providers of cloud who take care of the quality of the services. And the upgrades are provided at the vendor-end, again saving the time and money for the businesses. The upgrades are hassle-free and take no extra effort. When cloud provider updates their tools and solutions, they are made available to the customers at no additional cost.

With every passing day, cloud computing is expanding and there is an increase in the services available in the cloud. If you want to start using the cloud or want to know more about how to use it to your benefit, MarkSpace Media is the right place to go. Get in touch now.
