Apple’s iPhone In-Depth Architectural Look

We have by today already four generations of smartphone offered by Apple under the name of iPhone. And if we read all the news in different parts of the world number 5 is on the go. We could define the iPhone as being a multimedia-enabled smartphones from U.S. technology corporation Apple Inc. From all version of it, we will speak a little about the iPhone 4 anatomy.

In order to enjoy the full potential of this gadget I think it is well to know all the parts of it, inside and outside. If you have owned a previous version of this brand, iPhone 3GS that is, most things are already a common factor. Let’s take them part by part and dissect every component.

1st let’s speak a little about the design, size and weight of this device. All the models in the iPhone brand have been designed under a rectangular shape. About iPhone 4 we could add that it has been produced with a black or white aluminosilicate glass. The glass in particular is made from aluminium, silicon and oxygen. Other materials used include in most part stainless steel. The interaction between users and phones is made through a widescreen multi-touch display measuring 3.5 inches diagonally. Both models iPhone 4 and 3GS, have a height 4.5 inches and weight of 4.8 ounces. The factors that differs these two models are the width and depth. For iPhone 3GS we encounter a width of 2.4 inches and a depth of 0.48 inches. For the iPhone 4 model the numbers are 2.31-inch width and 0.37-inch depth.

But all those “exterior” things are useless if the technology inside the case isn’t state of the art. Let’s speak a little about the storage space, memory and processor. The 3GS model was created in three versions for flash memory storage space: 8GB, 16GB or 32GB. In all cases the RAM inside had the value of 256MB. With the new iPhone 4 model there were some changes made. 1st of all they eliminated the 8GB version. Also the quantity of RAM inside doubled reaching 512MB. That could be a reason why Apple Inc. only sold the 8GB version of the iPhone 3GS at the time of publication. Other technical details for iPhone 3GS would be an 833-MHz ARM Cortex-A8 processor. The 4th version offered a 1-GHz Apple A4 processor which is more powerful as the numbers show.

Leaving all those in-depth technical details let’s focus on camera and battery. Every iPhone model was built with a rechargeable lithium-ion battery and a camera. The difference was made by the performance of these components. One example would be that a 3GS battery produces a talk time of up to 12 hours and its camera produces 3 megapixels. It is obvious that things got an improvement with iPhone 4. In this case the battery has a talk time life of up to 14 hours. Although two more hours aren’t a “life saving” difference, more is always better I always say. A difference could be seen also on cameras. On this last model we encounter two of them, the front one made especially for video calls and with a 0.3 megapixel. The back one had also an improvement over it reaching a power of 5 megapixels.

Last but not least we will talk about the connectivity and interfaces. In every case, the iPhone model uses a Wi-Fi chip for wireless Internet service. Also you should know that iPhone 3GS was adhering to the Institute of Electronics and Electrical Engineers’ 802.11b/g duo of standards. In iPhone’s 4 cases we encounter IEEE 802.11b/g/n. Other external components would be a headphone jack and USB connector for charging the battery. Remembering some interfaces we should include in the list sleep/wake, volume up/down, ring/silent and home buttons.

These are basically the main components and some of the main stats of this wonderful device which is iPhone. Many more things could be said about Apple’s smartphone and this happens especially because iPhone 5 is on the horizon. Until the official release we could only speculate all the details, but I am sure none of us iPhone owners will be disappointed if we decide to purchase the new product. Let’s just hope the advancement in this piece of gadget won’t stop very soon because after all we are speaking here about the “king of smartphones” at this hour.
