Mobile cloud computing is a way of using the internet to do work with things like phones and computers, even when you're not near a computer. Instead of storing data, programs, and other information on the device (e.g. a phone or laptop) you use a cloud service so you can access it from anywhere. It's like having a big filing cabinet in the sky, where all your information is stored and you can get to it from any device like a laptop, tablet, or phone. This way you don't have to use up storage space on your device or have to move information from device to device.
