Gordon Moore, co-founder of Intel, predicted 50 years ago that the number of transistors fitted into smaller integrated circuits would be doubled approximately every two years. That was the baseline for the explosive growth of computing powers. The size of the electronic components slowly became smaller and the processing power of the devices got stronger as time went by.

The mainframe computers, used in the early 1960s and 1970s to run enterprises and large corporations, occupied the size of a living room. They subsequently shrunk to mid-range servers and desktop computers. Integrated circuit chips and microprocessors used in computers got more and more powerful, the size of the storage devices got much smaller, and the size of the storage capacity got increased.

Desktop computers slowly transformed to become more portable in the form of laptops and notebook computers. Laptop computers are equipped with a rechargeable battery that can let users work on their computers for their personal or business needs whenever and wherever they wanted.

The Personal Digital Assistant (PDA) is used as the mobile computing device for managing contacts and performing some basic business-related tasks.

Then came the era of smartphones. When Steve Jobs introduced the iPhone in 2007, there were some smartphones already available on the market. However, the introduction of iPhones by Apple and the subsequent launch of the Android platform by Google led the way to strong and healthy competition in the smartphone industry.

What we are seeing now in the wearable devices trend is history repeating itself. But this time, Google took an early lead in launching the Android Wear platform in 2014, whereas Apple announced its first wearable watch in April 2015.

Major companies such as Samsung, LG, Pebble, and Jawbone have all jumped onto this bandwagon with varieties of wearable device available on the market already.
