The advent of technology began with the introduction of the computing power of the ENIAC, the first computer to be ever built. Starting the construction in the year 1943 and not finishing till the year 1946, the Eniac was being built in the University of Pennsylvania which is quite a shock to me and many others as almost all the times the answer to a question like, “Where was the first computer ever built?”, is generally either Harvard or Stanford. Anyways, shaping the masterpiece of the future in an Ivy League university were J. Presper Eckert and John Mauchly. The fathers of the first-ever computer ever built were aware that the thing they are building will change the course of humanity for good and will do miracles that would have never happened before. 

Slowly but steadily the technology advanced and in the 90s finally we saw a haul in the tech industry. The idea back then was to create a dot-com service that would eventually land some money in pockets. To be a dot-com millionaire was the dream of everyone in Silicon Valley. The founders and associates of major players like Microsoft and Apple had already been declared billionaires by some fancy magazine whose annual subscription was more than I could afford back then.

How Android came and conquered?

The name of the Android OS has been for quite a while now in the tech industry and it is the only major player in the sector. According to The Verge, there are more than 3 billion Android devices running currently at this moment. The only threat that has ever emerged to it is from Apple in the form of iOS but Apple has never been able to overtake Android in the numbers game. The main reason for this is probably because of the limitation in the use of iOS to Apple devices only. Apple’s strict control over the user’s device and the end-to-end closed control over the OS is what has made them lose the numbers game.

The first version of android

The first version of android which publicly launched in 2008 marked the beginning of the good times which the tech enthusiasts have been waiting for quite a long time now. The launch of the first iPhone by Steve Jobs in 2007 was a major breakthrough but due to its end-to-end control over the software made the geeks quite disappointed as they were not able to play and fool around with it. For them, it was just a device that could only be used how the manufacturing company wanted it to be used. If they say that you cannot change how the icons look then you could possibly never be able to change the icons. The same was the case with everything an average consumer would like to play and fool around with.

Android Vs iOS

The consumers felt welcomed and warmth with Android and a sense of participation in how their device would look and how it feels to work with. The people were happy and the developers of Android were overwhelmed by the response they got from the public. Where iOS was based on pure monarchy, Android came and introduced Democracy to the market and won the battle. Android is still winning this battle due to the new and innovative technologies it has brought and supports. The capabilities with Android are just endless and can be stretched to any level.
