The Evolution of iPhone: The Technological Improvement

3년 전

Hello steemstem community;

I hope this will be a good medium to introduce myself to the community. My name is Babajide, I am a Mechanical Engineering student. I got to know about steemit and steemstem from some friends, @sogless and friends, and I immediately got interested in the idea because I love writing.

I’ve been observing the community for some days now and I pretty am aware of how things are being done in the community. With the help of some great guys like @sogless, @mrbreeziewrites and my mentor @katerinaramm, I’ve been able to pull something out.

For my first stem post I’m going to go into technology, I am going to be talking about the evolution of the popular Apple’s iPhone series. Most people use the iPhone and do not the technological advantages the iPhone holds, and when I talk of the technological advantages, I mean the specifications. So will be seeing the specifications your iPhone holds and the technological improvements the Apple iPhone series had over the years.

THINGS YOU SHOULD KNOW

Before I go into the main discussion of the day, I’ll like to talk about some terms I’ll be using as we go on.

GPU (Graphics Processing Unit): It is defined by wikipedia as “a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles”. It is the unit that is responsible for everything related to graphics as far as a system is concerned. As far as phones are concerned we have Adreno, Mali, PowerVR as examples of GPU. Apple used some the PowerVR GPU series for their iPhones until they introduced their own Apple GPU in the iPhone 8 series.

CPU (Central Processing Unit): It is defined by wikipedia as “the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.”. They are responsible for the execution of commands given to the system. Anytime you see CPU as we go on, note that it is the CPU speed rating I’m referring to.

Chipset: It is defined by google as "a collection of integrated circuits which are designed to function together as a unit, especially to perform a particular task within a computer system.”. They are responsible for the control of the communications between the processor and the external devices. Have it in mind whenever you see chipset that we’re talking about the chipset technology used.

WLAN (Wireless Local Area Network): It is defined by wikipediaas "a wireless computer network that links two or more devices using wireless communication within a limited area such as a home, school, computer laboratory, or office building. This gives users the ability to move around within a local coverage area and yet still be connected to the network.”. It is the technology responsible for linking the phone to a Wi-Fi network.

On Monday 3rd June, 2018, I went to get some sausage rolls from “Iya Mahmoud” to break my fast. I met some guys there arguing about whether or not iPhone 1 existed or not. A guy claimed he met and saw iPhone 1, iPhone 2, iPhone 3 whilst it existed. I didn’t argue as I also claimed I only know of the iPhone 4 which I met. When I got home I sat down and thought, why don’t you make this your first steemit article? And I told myself this is it. Mr Jide you have to work on the evolution of iPhone.

A SHORT STORY ON iPHONES

Most people just own an iPhone device without knowing the base. Who cares about base?, that’s the question most people will ask, but do you know what privilege you hold to be educated about the evolution of iPhones from the scratch?.

The apple iPhone is a series of digital devices which is a product of the Apple Inc. company. It is a phoning/telecommunication device that runs on an operating system owned by the Apple Inc. called the iOS. It has been in existence from the year 2007 to date with a lot of technological advancements coming through the years. It started with the iPhone which is the first generation of the series of the Apple iPhone brand and is currently with the iPhone X which is the latest iPhone in market.

The iPhone would have never been in existence if not for the intelligence of Late Steeve Jobs who was the CEO of Apple Inc. and his team. It all started with Steeve Jobs suggesting an investigation on how touchscreen will be of help to the development of devices. iTunes which is also a product of the Apple Inc. was then released in January, 2001 with an intention of synchronising devices with the iPod.

The first device to use this iTunes is the ROKR E1 which is a product of the partnership between Apple Inc. and Motorola and was released in September 7, 2005. In January 9, 2007, Steeve Jobs the managing director of Apple Inc. announced the iPhone at the Macintosh convention due to the fact he wanted something unique to the Apple Inc.
iPhone was later released in June 29, 2007 which is about a decade ago. It then ran in cycle untill it got to the latest iPhone X (2017) most of us wish to own.

THE EVOLUTION OF iPhones.

Yeah, due to the hard work of the Apple Inc. team, the iPhone didn’t stop with the iPhone, they had to work on more series as technology advances and from the look of things, technologically Apple Inc. is top notch.

Here below is the list of the Apple iPhone series from the first iPhone to the latest iPhone X.

  • iPhone
  • iPhone 3G
  • iPhone 3GS
  • iPhone 4
  • iPhone 4S
  • iPhone 5
