Enjoy technology 2023

61 TECHNOLOGY KNOWLEDGE BASE USB Type-C is a new form of data transfer cable first released in 2014. It can be used for charging and transferring data and can handle more power, so it’s used not only in phones and tablets but also in laptops. In addition, USB Type-C can handle 10Gbps transfer speeds, double that of USB-3. Next to that, the USB Type-C connector is small and reversible. The new standard also offers backward compatibility, so you can use adapters to connect USB-3 devices to USB Type-C devices. A USB Type-C cable also supports various protocols, such as Display Port, Power Delivery, and Quick Charge. All of this combined makes USB Type-C something of a unicorn connectivity tool. It has the power to become ubiquitous. ANC stands for Active Noise Cancelling which is a technology present in some headphones and earbuds that dampens disturbing ambient noise. This noise blocker is produced by capturing the surrounding sound through the built-in microphones in the headphones or earbuds. The sound then gets analyzed and twisted so that the person wearing the audio devise hears less ambient noise. This prevents the need to turn up the volume to compensate for background noise which is better for your hearing. ENC stands for Environmental Noise Cancelling which is a different technology found in some headphones and earbuds that come with a microphone function. Background noise is suppressed by recording the sounds in the environment and then process them to create a opposite cancelling sound which will neutralize the noise. This way the speaker’s voice will be heard clearly over the background noise. As the technology evolved throughout the years, Bluetooth improved. Each version improved the data transfer speed, connection range, stability, security, and energy efficacy. We are currently on 5.3. Below are the five main versions of Bluetooth: Version Year Data Transfer Speed Maximum Range Feature Introduced 1.0 1999 732.2 kbit/s-2.1 Mbit/s 10 meters Speech only 2.0 2004 2.1 Mbit/s-24 Mbit/s 10-30 meters Enhanced Data Rate (EDR) 3.0 2009 24 Mbit/s 30 meters High Speed (HS) 4.0 2010 24 Mbit/s-25 Mbit/s 60 meters Bluetooth Low Energy (BLE) 5.0 2016 25 Mbit/s-50 Mbit/s 240 meters Dual Audio Connection We could say that Bluetooth 5.0 has laid the basis for the new family of versions of this protocol. The last major update revolutionized Bluetooth 4, doubling the speed of file transfer and quadrupling the range, which is the distance over which data can be transferred between them. Since then, the rest of the versions have simply been refining small things. WHAT IS USB TYPE-C? Efforts to reduce waste mean that most modern phones no longer come with a charger. If you use an Android phone or iPhone, chances are you have several or more chargers in and around your home. With the new USB Type-C standard, you won’t need a new charger every time. This also means that it won’t be necessary for the tech manufacturer to include one with every product. Which will help them save billions of tons of materials every year. When you switch to one common standard, your life - as a consumer - also becomes easier. You’ll have a phone, laptop, tablet, and e-reader all using a USB Type-C cable – by 2024 it’s expected that even more peripherals will shift to USB Type-C as well. In the past, different cables were needed to charge each one of them. However, with a USB Type-C cable, you only need one USB Type-C cable to charge them all. And that’s why regulators are now making huge efforts to make USB Type-C the standard charging protocol for all electronic devices. USB TYPE-C is more environmentally friendly BLUETOOTH TECHNOLOGY ANC VS ENC MORE ON NFC A few examples of NFC use cases include the following: • Mobile payments, such as Apple Pay and Google Pay • Public transport card payments • Access authentication for doors or offices • Unlocking car doors or rental scooters • Device pairing smartphones and headsets by tapping them together • Automatic setup for Wi-Fi connectivity by tapping a phone to a router or internet gateway
