As an AI language model, my knowledge cutoff is September 2021 and I cannot predict the future. However, I can tell you some of the technologies that were trending in 2019:

Artificial Intelligence (AI):

Artificial Intelligence (AI) is a field of computer science that aims to create intelligent machines that can learn, reason, and perform tasks that normally require human intelligence. The process by which AI works can vary depending on the specific application, but here are some general steps that an AI system might follow:

  1. Data Collection: An AI system needs data to learn from. This data can come from various sources, such as sensors, databases, or user input.
  2. Data Preprocessing: The data collected may be in different formats and may contain noise or errors. So, the data needs to be preprocessed to ensure that it is clean, structured, and in a format that the AI system can understand.
  3. Training: In the training phase, an AI model is created and optimized using the preprocessed data. The model is trained to recognize patterns in the data and make predictions or decisions based on those patterns.
  4. Testing and Validation: Once the model is trained, it needs to be tested and validated to ensure that it performs well on new data that it has not seen before.
  5. Deployment: After the model has been tested and validated, it can be deployed in a production environment where it can perform the task it was designed to do.
  6. Continuous Learning: AI models need to be continuously monitored and updated to ensure that they continue to perform well over time. New data can be used to retrain the model and improve its performance.

The above steps are just a high-level overview of how AI works. The specific implementation of AI will depend on the application and the algorithms used.

Internet of Things (IoT):

The Internet of Things (IoT) is a system of interconnected physical devices, vehicles, appliances, and other items that are embedded with sensors, software, and network connectivity, allowing them to collect and exchange data. The following are the basic steps on how IoT works:

  1. Sensors and Devices: IoT devices typically have built-in sensors or can be connected to sensors that gather data about their environment. These sensors can collect a wide range of data, such as temperature, humidity, motion, light, and sound.
  2. Data Collection and Processing: Once the data is collected, it is transmitted to a central processing system, either in the cloud or on-premises, where it can be stored, analyzed, and processed. The processing system can use machine learning algorithms or other analytical tools to derive insights from the data.
  3. Connectivity and Communication: IoT devices are typically connected to the internet through Wi-Fi, cellular, or other wireless or wired networks. This allows them to communicate with each other and with the central processing system, enabling data exchange and control commands.
  4. Applications and Services: The data collected by IoT devices can be used to power a wide range of applications and services, such as smart homes, smart cities, industrial automation, healthcare, and transportation.
  5. Security and Privacy: With the growing number of IoT devices, security and privacy are becoming increasingly important. IoT devices must be designed with security in mind, with features such as encryption, authentication, and access controls, to protect the data and prevent unauthorized access.

Overall, IoT works by connecting physical devices to the internet and leveraging the data they generate to enable new applications and services.


The blockchain is a distributed ledger technology that allows for secure, transparent, and decentralized record-keeping. Here are the basic steps on how the blockchain works:

  1. Transactions: A transaction is created when a user wants to send cryptocurrency or digital assets to another user. Transactions are verified and validated by the network of users, known as nodes.
  2. Verification and Validation: Nodes on the blockchain network use complex algorithms to verify and validate transactions. Transactions are verified by ensuring that the sender has sufficient funds and that the transaction is valid. Once a transaction is verified, it is grouped with other transactions into a block.
  3. Block Creation: Blocks contain a set of verified transactions and a unique cryptographic hash that identifies the block. Miners on the network compete to create a new block by solving a complex mathematical problem. The first miner to solve the problem is rewarded with cryptocurrency.
  4. Consensus: Once a block is created, it is broadcasted to all nodes on the network. Nodes use a consensus algorithm to agree on the validity of the block. Once a block is added to the blockchain, it cannot be altered or deleted.
  5. Distributed Ledger: The blockchain is a distributed ledger, meaning that a copy of the entire ledger is stored on every node on the network. This makes it virtually impossible for any single user or entity to tamper with the blockchain.

Overall, the blockchain works by creating a decentralized and secure ledger that allows for transparent record-keeping. It achieves this through the use of complex algorithms, cryptographic hashes, and consensus mechanisms that ensure that transactions are verified and validated by the network of users.

5G Networks:

technology trend in 2019

5G networks are the latest generation of cellular network technology and are designed to offer faster data speeds, higher bandwidth, and lower latency than previous generations of cellular networks. Here are the basic steps on how 5G networks work:

  1. Radio Frequency (RF) Spectrum: 5G networks use a combination of low, mid, and high-band frequencies to transmit data. Low-band frequencies offer wider coverage, while high-band frequencies offer faster data speeds.
  2. Antennas and Base Stations: 5G networks require a denser network of antennas and base stations compared to previous generations of cellular networks. These antennas and base stations work together to transmit and receive data between the user’s device and the cellular network.
  3. Small Cells: 5G networks also use small cells, which are low-power base stations that are deployed in densely populated areas, such as urban centers or stadiums. Small cells help to improve coverage and capacity in areas with high demand.
  4. Massive MIMO: 5G networks use Massive Multiple Input Multiple Output (MIMO) technology, which allows multiple antennas to be used to transmit and receive data simultaneously. This helps to increase capacity and improve data speeds.
  5. Network Slicing: 5G networks also support network slicing, which allows for the creation of multiple virtual networks on a single physical network. This allows network operators to customize the network to meet the specific needs of different applications, such as autonomous vehicles or remote surgery.
  6. Edge Computing: 5G networks also support edge computing, which allows data processing and storage to be done closer to the user’s device. This helps to reduce latency and improve application performance.

Augmented Reality (AR) and Virtual Reality (VR):

Augmented Reality (AR) and Virtual Reality (VR) are two related technologies that allow users to experience digital content in a more immersive way. Here are the basic steps on how AR and VR work:

Augmented Reality (AR):

  1. Input: AR requires input from a camera or other sensors to capture the real-world environment.
  2. Tracking: The AR system tracks the user’s location and movements in real-time.
  3. Rendering: The AR system overlays digital content onto the real-world environment in real-time. The digital content can be in the form of text, images, videos, or 3D models.
  4. Output: The user sees the real-world environment with the digital content overlaid on it through a device such as a smartphone or AR headset.

Virtual Reality (VR):

  1. Input: VR requires input from a camera or other sensors to capture the user’s movements.
  2. Rendering: The VR system generates a 3D virtual environment in real-time based on the user’s movements and input.
  3. Output: The user sees the virtual environment through a device such as a VR headset. The device also includes motion sensors to track the user’s head movements and adjust the view accordingly to give the user the sensation of being fully immersed in the virtual environment.

It’s worth noting that while some of these technologies were trending in 2019, they continue to evolve and remain relevant today.
