In today’s world, it’s hard to imagine life without technology. We’ve come to rely on it for so many things, from staying connected with our loved ones to getting our work done. But what technology do we have today that we didn’t have just a few years ago?

Mobile technology
These days, technology is everywhere. You can find it in your home, your office and even in your pocket. Mobile technology has come a long way in recent years, and there are now a variety of devices that can help you stay connected to the people and information you need.
Smartphones are perhaps the most popular type of mobile device, and they come in a range of sizes and styles to suit different needs. Whether you want a simple device for making calls and sending messages, or a more sophisticated option with a range of apps and features, there’s a smartphone to suit you.
Tablets are another type of mobile device that have become increasingly popular in recent years. They offer many of the same features as smartphones, but with a larger screen that makes them ideal for tasks such as browsing the internet, reading books or watching movies.
Wearable technology is another area that has seen significant advances in recent years. Devices such as fitness trackers and smartwatches can help you keep track of your activity levels, monitor your heart rate and even make payments without taking your phone out of your pocket.
Wearable technology
Wearable technology, also called “wearables”, is a category of electronic devices that can be worn on the body. The most common wearable technology devices are fitness trackers, smartwatches and wearable medical devices. Fitness trackers are worn on the wrist like a watch and track things like steps taken, heart rate and calories burned. Smartwatches are also worn on the wrist and run apps like a smartphone, allowing the user to do things like check email, make phone calls and access social media. Wearable medical devices are designed to help people with chronic health conditions manage their condition or monitor their vital signs.
Augmented reality
AR technology has been around for years, but only recently has it begun to be used in consumer products. AR apps are now available for smartphones and tablets, and AR hardware is being developed for use in homes, cars, and workplaces.
AR technology can be used for a variety of purposes, from providing information about the world around us to helping us interact with digital content. For example, AR apps can be used to give directions, identify landmarks, or provide information about products. AR hardware can be used to create immersive experiences, such as virtual reality (VR) or mixed reality (MR) environments.
Some of the most popular AR apps and hardware include Google Glass, Microsoft HoloLens, Oculus Rift, and Samsung Gear VR.
Virtual reality
Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality include entertainment (e.g., video games) and education (e.g., medical or military training). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR.
3D printing
3D printing is a process of making three-dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes, where successive layers of material are laid down in different shapes. 3D printing is the opposite of subtractive manufacturing, where material is removed from a piece of stock to create the desired shape.
3D printing refers to various processes that can be used to create three-dimensional objects. The most common 3D printing process is called fused deposition modeling (FDM). In this process, the material to be printed (usually plastic filament) is fed into a extruder, which melts the material and deposits it layer by layer according to the instructions in the digital file. FDM is a relatively slow process, but it can be used to create complex shapes with high accuracy. Other 3D printing processes include stereolithography (SLA), selective laser sintering (SLS), and direct metal laser sintering (DMLS).
SLA uses a laser to cure (harden) layers of photopolymer resin, while SLS uses a laser to fuse together powdered metals or plastics. DMLS is similar to SLS, but it uses a higher-powered laser to fuse together metal powder. These processes are generally much faster than FDM, but they are also more expensive.
Drones
Drones are becoming increasingly popular, both for personal and commercial use. There are a variety of different types of drones available on the market, from simple toys to complex flying machines. Drones can be used for photography, videography, mapping, and even delivery.
Internet of Things
The Internet of Things (IoT) is a network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, and connectivity which enables these objects to connect and exchange data.
The term “Internet of Things” was first coined by Kevin Ashton in 1999 while working on a presentation for Procter & Gamble. However, the concept of an interconnected network of devices can be traced back to the early days of radio and television. The idea was further developed in the 1980s by researchers at Carnegie Mellon University who created a wireless sensor network called “EARS” which was used to monitor buildings and infrastructure.
In recent years, IoT has been gaining popularity due to the advancement of technologies such as wireless networking, sensors, and Big Data. IoT has the potential to revolutionize many industries such as healthcare, transportation, manufacturing, retail, and more.
Big data
Big data is a catch-all term for data sets so large or complex that traditional data processing tools are inadequate. Handling big data requires new ways of data capture, storage, analysis and visualization.
The notion of big data has been around for a long time, but it’s only in recent years that technology has progressed to the point where we can actually make use of it. Thanks to advances in hardware, software and networking, we now have the ability to store, process and analyze huge amounts of data quickly and efficiently.
This is having a transformational effect on a whole host of industries, from retail and healthcare to finance and manufacturing. And as our ability to collect and process data continues to increase, the potential applications are endless.
Cloud computing
Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
Blockchain
A blockchain is a digital and distributed ledger that records transactions in a secure, tamper-resistant way. Transactions are recorded and validated by a network of computers, rather than by a central authority. This makes blockchains highly resilient to fraud and tampering.
Blockchains are often used to validate and record cryptocurrency transactions, but they can also be used for other types of data. For example, a blockchain could be used to record the ownership of assets like land or diamonds.
The first blockchain was created in 2009 as part of the Bitcoin protocol. Since then, numerous other blockchains have been created, with each one tailored to meet the specific needs of its users.
