Emerging technologies are transforming how we live, work, and interact... Show more
Ever wondered why your Netflix sometimes buffers or why businesses seem obsessed with the latest tech? Emerging technologies are putting massive strain on our existing IT systems, and understanding this helps explain many of the digital challenges we face today.
An early adopter is someone who jumps on new technology before everyone else - think of the people queuing for the latest iPhone or trying new apps first. These users often drive demand that can overwhelm current systems. For example, when everyone started streaming Netflix during lockdown, it put enormous pressure on internet infrastructure that wasn't designed for such heavy use.
The rise of Voice over Internet Protocol (VOIP) - like WhatsApp calls or Zoom - has created similar challenges. These calls can't be delayed like regular data, so they need priority treatment as they travel through networks. This creates quality of service issues that network providers must constantly manage.
Key Point: Technology is now expected to be "always on", creating constant pressure on systems to perform flawlessly whilst handling exponential data growth.
On a personal level, we now access more information daily than previous generations saw in their entire lifetimes. This has revolutionised communication through social media and emails, though it's also made us more susceptible to impulse purchases and get-rich-quick schemes through targeted advertising.
Despite the challenges, emerging technologies offer incredible benefits that are reshaping how we live and work. You can now keep in touch with family worldwide through text, email, and social media, whilst having instant access to global news, entertainment, and high-quality photography right in your pocket.
For businesses, technology has enabled global sourcing and international marketing like never before. Companies can now find suppliers anywhere in the world and reach customers across continents. However, this comes with significant costs - expensive equipment, maintenance, staff training, and accommodation needs can quickly burden organisations.
The real game-changer is how IT systems enable high-risk operations that would be dangerous for humans. Think data mining in hazardous environments, space exploration, delicate medical procedures, or unmanned devices handling disasters like Fukushima. These applications show technology's potential to protect human life whilst achieving previously impossible tasks.
Key Point: Businesses must balance the incredible opportunities of global connectivity against the substantial costs of implementing and maintaining advanced technology systems.
Artificial Intelligence exemplifies this balance - from self-driving cars to chess-playing computers, AI relies on deep learning and natural language processing to perform human-like tasks. Meanwhile, blockchain technology creates permissionless networks maintained indefinitely without central authorities, revolutionising how we think about digital transactions and data security.
The technology landscape is evolving rapidly with innovations that will shape your future career and daily life. 5G networks represent the fifth generation of mobile connectivity, offering incredible speeds that make 4G look sluggish. This enables everything from seamless video streaming to complex Internet of Things (IoT) applications.
IoT technology transforms ordinary objects into smart devices - imagine your car automatically booking its own service or your home lighting adjusting based on your daily routine. Machine Learning, a branch of AI, continuously improves its accuracy by learning from data, making systems smarter over time.
Virtual Reality (VR) creates entirely new digital worlds through specialised headsets, whilst Augmented Reality (AR) overlays digital elements onto the real world - think Pokémon GO or Instagram filters. Cloud computing provides on-demand access to computing resources via the internet, eliminating the need for expensive local hardware.
Tesco's "Scan Pay Go" technology demonstrates both the potential and pitfalls of emerging tech. Customers can scan items on their smartphones and walk out without visiting a till, but trials revealed unexpected challenges: battery anxiety, confusion about bags, discomfort when leaving without seeing staff, and concerns about security.
Key Point: Fintech (financial technology) innovations like mobile banking apps and contactless payments are reshaping how we handle money, whilst voice assistants like Siri and Alexa are making hands-free device control commonplace.
These real-world applications show that whilst emerging technologies offer exciting possibilities, successful implementation requires careful consideration of user experience and practical challenges.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
