SMARTWATHCES

A smartwatch is a wristwatch with screen and the ability to do much more than tell you the time.They are wearable comuputers,that can  run mobile apps, using a mobile operating system. They can be used as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, also called 'watch phones', feature full mobile phone capability, and can make or answer phone calls or text messages.

Smartwatches have an electronic visual display,a rechargeable battery and touchscreen. Peripheral devices  include digital cameras, thermometers, accelerometers, altimeters, barometers, compasses, GPS receivers, tiny speakers, and SD card .Software include digital maps, schedulers and personal organizers, calculators, and different watch faces. It supports wireless technologies like Bluetooth, Wi-Fi, and GPS.

How do they work??


Watches can cooperate with an app in a smartphone to carry out their functions,for which they are paired, usually by Bluetooth, with a smart phone. Some of these only work with a phone that runs the same mobile operating system; others use a unique watch OS. Paired, the watch may function as a remote to the phone. This allows the watch to display data such as calls, SMS messages, emails, and calendar invites, and any data that may be made available by relevant phone apps.

Everyday Cloud !!

Cloud Computing - delivering hosted services over the Internet. Cloud computing is getting IT services, such as email, customer relationship management or web conferencing, over the internet.Instead of buying hardware and software up front, you pay a monthly charge based on the number of users.In simple words,when you  type a query into Google, the computer does nothing with regards to answer, it's just a messenger. The words you type are sent over the Net to one of Google's numerous clustered PCs, which find  your results and send them promptly back to you. The real work in finding your answers might be done by a computer sitting in California, Dublin, Tokyo, or Beijing!!Preparing documents over the Net is a newer example of cloud computing.
