Why was Apple forced to switch to USB-C?

Shreyas Sen

Apple recently announced that it plans to adopt the USB-C connector for all four new iPhone 15 models, helping USB-C become the connector of choice of the electronics industry, nine years after its debut. The move puts Apple in compliance with European Union law requiring a single connector type for consumer devices.

USB-C is a small, versatile connector for mobile and portable devices like laptops, tablets and smartphones. It transfers data at high speeds. transmits video signals and delivers power to charge devices batteries. USB stands for Universal Serial Bus. The C refers to the third type, following types A and B.

The USB Implementers Forum, a consortium of over 1,000 companies that promote and support USB technology, developed the USB-C connector to replace the older USB connectors as well as other types of ports like HDMI, DisplayPort and VGA. The aim is to create a single, universal connector for a wide range of devices.

The key features and benefits of USB-C include a reversible connector that you can insert in either orientation. It also allows some cables to have the same connector on both ends for connecting between devices and connecting devices to chargers, unlike most earlier USB and Lightning cables.

USB-C’s widespread adoption in the electronics industry is likely to lead to a universal standard that reduces the need for multiple types of cables and adapters. Also, its slim and compact shape allows manufacturers to make thinner and lighter devices. USB-C refers to the physical connector. Connectors use a variety of data transfer protocols – sets of rules for formatting and handling data – such as the USB and Thunderbolt protocols.

The latest USB protocol, version 4, provides a data transfer rate of up to 40 gigabits per second, depending on the rating of the cable. The latest Thunderbolt, also on version 4, supports up to 40 gigabits-per-second data transfer and 100 watts charging. The newly announced Thunderbolt 5 will support up to 80 and 120 gigabits-per-second transfer and 140 to 240 watts power transfer over a USB-C connector.

Since its introduction in 2014, USB-C has gained widespread popularity and has already become the connector of choice for most non-Apple devices. Apple converted the iPad Pro to USB-C in 2018 and now is doing the same for the best selling Apple device, the iPhone.

Thanks to the industrywide adoption of USB-C, consumers soon won’t have to ask “Is this the right connector?” when they reach for a cable to charge or sync their portable devices. (This article is republished from The Conversation under a Creative Commons licence.)

What do driverless cars use to determine the best route or course of action when travelling from one location to the next?

From finding the fastest path to a cafe to self-driving cars, modern necessities and benefits rely upon something that many take for granted: the Global Positioning System (GPS). GPS is so deeply ingrained into our daily lives that it’s difficult to picture a world without it, but did you know where it came from?

The origin of GPS

In the middle of the 1960s, the US Navy experimented with satellite navigation to follow U.S. submarines that were carrying nuclear weapons. The Department of Defence (DOD) decided to employ satellites to support their scheduled navigation system in the early 1970s because they wanted to make sure that it was a reliable, stable system, based on previous ideas from navy scientists. In 1978, the Department of Defence launched the first Navigation System with Timing and Ranging (NAVSTAR) satellite which later changed into GPS. In 1993, the 24-satellite constellation went into full functioning. It was initially intended to replace earlier navigation systems and locate military transportation equipment worldwide with accuracy. Over time, the GPS evolved into an easily available, free device that improves daily safety and comfort together

The Pioneers behind GPS

Despite being created by the U.S. Department of Defence, a few scientists have been recognized as having made significant contributions to this ground-breaking technology. Roger L. Easton led the Space Application division of the Naval Research Laboratory. Timing technology and circular orbits are two of the most important aspects of GPS that he specialised in as a Cold War scientist. As the first manager of the Navstar GPS programme, Brad Parkinson contributed to the program’s conception and early to mid-stage implementation. Dr. Ivan Getting was the founding president of The Aerospace Corporation and drove the GPS’s launch. To pinpoint their precise location, Dr. Gladys West first worked at the U.S. Naval Weapons Laboratory, where she calculated equations and analyzed satellite data.

How Does GPS Work?

Satellites, ground stations, and receivers make up the three components of the GPS. 13 satellites transmit radio signals that provide precise time and location derived from onboard atomic clocks. At a speed of 300,000 kilometres per second or the speed of light, these signals travel across space. The precise location of these satellites is verified by ground stations by receiving their signals. A computer, an atomic clock, and a radio are installed on every satellite. It continuously sends its position and time shifts since it recognizes the Earth’s orbit and the clock. The scientific use of the GPS is offering historically beyond-reach data in exceptional amounts and with extraordinary clarity. The movement of the polar ice sheets, the tectonic plates of Earth, and volcanic activity are all being measured by scientists using GPS. Ever wondered how birds find their way?

If you were lost in the middle of the woods and couldn’t see the sun, you might use a compass to figure out which way to go. For more than a thousand years, people have used magnetic compasses to navigate. But how do the other birds find their way?

The Earth’s magnetic field is recognized for shielding the planet and its people from risky cosmic rays and plasma emitted by the sun. However, birds use this magnetic field for navigation in a unique manner, similar to a GPS, and they can turn it on and off with great flexibility. Researchers have discovered two factors that are essential to a bird’s internal GPS: eyesight and scent. The perfume is unusual because we don’t typically associate birds with a sense of smell. The scent, it turns out, plays an important role in helping birds navigate. A bird can identify magnetic fields visually, allowing it to use a visual compass to navigate over long distances. Scientists have discovered a protein called cryptochromes in their retinas that enables signalling and sensing activities, assisting birds in navigating the great distances they travel while migrating.

Researchers detected a little magnetite area on the beaks of several birds. Magnetite is a magnetised rock that functions as a miniature GPS device for birds, providing information about its position relative to the Earth’s poles. Birds are considered to be able to navigate vast distances across places with few landmarks, such as the ocean, by using both beak magnetite and eye sensors.

What is Creative Destruction?

 

The eighties and nineties were the era of VHS tapes. Invented by the Japanese company JVC, Video Home System (VHS) – or the ‘deck’ as it was locally known – was an instant hit around the world. Even in small towns of India, video shops that rented VHS players and cassettes were a lucrative business.

The era, however, did not last long. Along came the Compact Discs. Music, movies, data files – the flashy CDs could store anything. They could be played on TVs (hooked with CD players) and computers. Today, whatever CDs are left behind are used as reflectors on bicycles or for art-from-waste projects.

Streaming and cloud storage have made the CD obsolete, just like its predecessor. Tomorrow, the streaming system could be replaced with something else. This process of evolution of technology – from VHS tapes to streaming platforms or landline phones to smartphones – is called Creative Destruction.

The technological advancements defined above are recent, but the concept of creative destruction has been defined and debated by economists, sociologists, and political thinkers since the 19th century. The industrial revolution and colonialism were the two defining historical events that shaped its definition.

Foundational theories

 Creative Destruction is a critical component of the capitalist system of economics and politics.Yet, a first clear definition for the  process was given by the father of communism –an opposing economic and political throught Karl Marsx. Though he did not use the term Creative Destruction, he defined the concept as a ‘’contant upheaval and change within the capitalist system.’’

In his exhaustive work tirled, ‘capital; Acriyique of Political Economy; published as three volumes in 1867, 1885, and 1894. Marx writes: “The bourgeoisie cannot exist without constantly revolutionizing the instruments of production, and thereby the relations of production, and with them the whole relations of society.”

This encapsulates the process of technological innovations that we see today. Take for instance the case of Artificial Intelligence (AI). It is the new “instrument of production that is replacing older technologies and even humans in some cases. As a result, the “relations of production also changes, with new skills becoming essential for upward mobility in the job market. The “relations of society” has also changed as engineers with Al skills now draw higher pay packages compared to engineers in other sectors.

Much later, in the 20th Century, German economist Joseph Schumpeter popularized the term Creative Destruction, which was coined by another.

German economist Werner Sombart. In his book Capitalism, Socialism and Democraay, published in 1942. Schumpeter extrapolates the Marxist thought to describe the destructive process of a transformation caused by innovation for instance, the slow death of landline phones.

Schumpeter says Capitalism is a method of economic change which can never be stationary. The fundamental impulse that keeps the system running is new consumer goods, new methods of producing or transporting them, new markets to sell them, and new forms of organisations that the system creates. This is a fairly accurate description of how businesses work in our world today.

Modem examples

Schumpeters work is pretty accurate in defining the current startup era. He says innovative entry by entrepreneurs is the disruptive force that sustains economic growth, even as it destroys the value of established companies that enjoyed some degree of monopoly. A classic example for this is the case of social media eating into the market control of mainstream medin

However, Schumpeter was pessimistic about the sustainability of this process. Seeing it as leading eventually to the undermining of capitalism’s own institutional frameworks. The capitalist process in much the same way in which it destroyed the institutional framework of feudal society abo undermines its own, he said.

Today, most technology majors are focussed on continuous innovations that push boundaries of human imagination. As we grapple to get a grasp over the everevolving trends in technology, its important to leam about the great minds that prophesied this era.

What is the history behind QR code?

“Can you please scan the code,” is one of the most common phrases used during transactions in today’s digital world. QR codes are ubiquitous these days-in cafes, bazaars, roadside fruit carts, and even at pani puri stalls. A whole range of consumer and businesses have adjusted to the digital world that has brought QR codes back, especially in the last few years with the advent of the cashless economy. However, have you ever wondered who designed the QR Code and for what purpose?

The invention of the QR Code

Similar to the evolution of several technologies, QR Codes originated from necessity. In 1994, a Japanese company called Denso Wave invented the QR code, which was used to label car parts. The idea was to replace the numerous bar-code labels that had to be scanned on each box of auto parts with a single label that contained all of the data from each label, making it easier to keep track of the different kinds and quantities of car parts. Following that, there was an increased interest in more product traceability across the world, particularly in food and pharmaceuticals.

The International Organization for Standardisation (ISO) added the QR Codes to their list in the year 2000, giving it international certification. They rapidly understood the significance of the QR code and began using them in production, shipping and transactions. Later on, with the development of smartphones, there was no slowing in increasing the utilisation of the QR codes’ popularity.

How QR Code is helping the world?

Undoubtedly, using QR Codes to access websites, networks, and payment details is the quickest method. To get started, all someone has to do is scan the code and do not need to enter any URL.

Among the numerous advantages of QR codes are their increased sustainability and the ability to update information without having to print brand-new materials. They are also utilized to communicate information on leaflets, packaging, and store displays in addition to serving as mobile menus and facilitating contactless payments. Without requiring prior knowledge or financial education to utilise them for payments, QR codes facilitate the digital shift and provide a positive user experience. The three steps of starting an app, scanning a QR code, and entering an e-PIN are easy and fast. A digital revolution is endlessly possible with QR codes’ innovative and engaging way of bridging the real and virtual worlds.

What is AI fiction?

Al fiction is a constantly evolving genre that gives us a peek into the potential umides and downsides of intelligent machines whether it is books written by humans with robots and Al as central characters or stories composed entirely by machine learning algorithms. Al fiction never fails to captivate readers and stimulate discussions about what is in store for technology in the future. Artificial intelligence hum long barn a popular topic in soner fiction from haar

One recent devettipment in Al fiction is the merger of novels written retimly by artial de The first Al generated novel 1 the Road caine at in 2018 hased on data gathered by namically exhand ca on a road trip from New York to New Orleans it was moted by an operimental 2016 sort story co-written by Al and sapanese researchers troulated as The Day a Computer Visite a Novel which nearly won a literary prize. In the same year, Sunspring, an Al-authored screenplay, was placed in the top 10 at a London sci-fi film festival. In the first year of the pandemic, we got Pharmako-Al, a genre-bender philosophical book co-written by an Al and K. Allado-McDowell, founder of Google’s Artists and a machine intelligence programme, GPT-3. These experimental works of fiction represent an intriguing new avenue for Al fiction. With machine learning algorithms capable of generating coherent narratives and dialogue, it is possible that we may soon see a flood of novels, stories, and even movies written entirely by Al.

Science fiction (sci-fi) & Al

For generations, sci-fi has foreseen the pervasive influence of Al in our daily life. Its representation in mainstream media has played a pivotal role in shaping public opinions towards this technological advancement Films such as The Terminator and Ex Machina have helped to shape the cultural narrative around Al, with many people viewing intelligent machines as potential threats to human safety and autonomy. At the same time, this type of speculative fiction has also explored the more positive aspects of Al, from the helpful robots of Wall-E to the benevolent supercomputers of 2001: A Space Odyssey. As Al technology continues to evolve, it’s likely that all the good, bad, and ugly visions of intelligent machines will continue to be explored in fiction.

How does the internet connect across continents?

It connects through a vast undersea network of fibre optic cables across countries and continents.

 Fibre optic cables lie submerged on the ocean floor across the Earth. These cables allow us to quickly send our emails and videos, and connect our browsers to places in far-away lands.

To put it simply, when we open an Australian website in Mumbai our PC sends a signal through the submarine cable to the web server that is hosting that website and then receives the data of the website in return over the same cable.

Earlier communication satellites were used to transmit data, but since optical fibres are capable of transmitting large volumes of data at a much faster speed, submarine cables have come to be used instead in most cases. Submarine cables now account for more than 99 per cent of all international communications.

The first submarine communications cables were laid in the 1850s to send telegraphs. Modern cables use optical fibre technology to carry digital data. There is a massive network of submarine fibre optic cables that connects a large portion of the continents except Antarctica.
