5 Technological Inventions That Changed The World

Technological advancements are the reason that we have bid farewell to the old customs and practices that required a lot of effort and time. Today, technology has been making everything easier for us.

Today, we have automatic cars that drive on their own, smartphones to connect anywhere in the world and microwave to prepare our food in minutes. All of this is due to science and technology.

It won’t be wrong to say that these and many other inventions have actually changed the course of our world.

Let’s have a look at 5 such technological inventions:

  1. Alexa

Who would have thought that there’d be a highly intelligent voice-controlled system in our homes that would perform various tasks on voice commands? This looked like a distant dream once but today we have Amazon Echo’s Alexa doing that quite well.

There’s a fun element to this device that it powers on (wakes up) when you call its name, “Alexa”. It’s like having a personal assistant who is there with you to listen to your commands and do as you say.

Besides playing music for you, Alexa can do a number of other things as well. It can link to a smartphone or tablet using Bluetooth and even sync files.

You can also utilize the Wikipedia knowledge feature to seek answers to your questions. You don’t need to connect your phone and type in the words, simply shoot a question towards Alexa and it will run a scan and provide you with an answer.

Many say that this is just the beginning. Amazon is already working on upgrades that may be even better. This is undoubtedly the future.

  1. HDMI Cables

Listening to music and watching your favorite movies is fun thanks to USB cable manufacturers. Back in the days, it was common to connect DVD players to TVs and enjoy movies. However, the quality offered by the conventional audio and video cables didn’t live up to the expectations and failed at providing the fine details.

However, everything changed when HDMI cables stepped into the play. They offer top-notch quality and you get to enjoy great visuals and sound on your display.

HDMI cables transmit data digitally. This means that there’s no loss of data or any kind of conversion involved that would deteorite the signals. Hence, what you see and hear is picture-perfect.

  1. LEDs

Traditional lights were a real bank breaker and spiked the electricity bill to the roof. However, thanks to the contribution of Nakamura, Nagasaki, and Amano, LED technology was introduced.

It not only reduces our energy bills to a great deal but is more durable and lasts for a longer period of time compared to conventional lights.

LEDs can last fifty times longer than incandescent bulbs and 8 to 10 times more than CFLs.

They are not only pocket-friendly but environmental friendly as well.

  1. CCTV System

CCTV technology was founded by a German engineer named Walter Bruch. His aim was to monitor the V2 rockets when they were launched into the space.

However, this idea got so much popularity and fame that CCTV technology is now found at every nook and cranny in the country. It has reduced crime rates dramatically and is doing humanity a huge favor.

  1. Robots

A lot of giant tech companies with their valuable efforts succeeded in making friendly robots that work on AI. These robots can interpret human communication and even perform some difficult tasks.

In fact, there’s already a restaurant in Japan that’s completely run by robots. Many predict 30% of all the jobs will be done by robots by 2030.

The Conclusion

Technology has definitely made our lives easier but it also poses certain challenges. At the end of the day, it’s largely about how you use the latest technology.
