In its ancient age of computers the size of computers was too much big such that it occupies a space of approx two rooms. After invention of Integrated Circuits its size becomes much small. In the middle era of computers we were using desktop computers which can be fitted on a small desk. At present we are using Laptops and Smartphone, which helps us to do our computing task anywhere. We can take these computing devices with us everywhere. In other words we can say that we can carry our office with us. The new era that we are seeing in past few years or that we will see in next few years is the era of Wearable Computers. Spy camera, Spy voice and video recording device, watch with computer, Spectacles with computing capabilities are few examples of this kind of devices.
