Mobile Computing is computing done by users that connect intermittently with each other across a wireless network. The computing device can take many different popular forms such as:
PDA's or Personal Digital Assistants commonly referred to as handhelds.
Cell phones, many of which are now hybrid devices containing powerful computing processors capable of sophisticated client side processing.
Laptops, notebooks, and tablet computers.
The data transmission, user authorization, and traffic management protocols involved in mobile computing are the heart of the wireless computing revolution. The most dominant protocol involved with wireless networking is 802.11n. This protocol refers to a family of specifications developed by the IEEE for wireless networking. The 802.11 specification concerns itself with the connection between a wireless client and a base station, or between two wireless clients, across an over-the-air network connection.
The most popuplar mobile computing device as of today is the cell phone (mobile phone). Other popular mobile devices are GPS devices, Notebooks, NetBooks, E-Book Readers and even wristwatches, that can provide data on location, calories, pulse and physical data. Electronic cameras are one of the modern mobile computing device operated with a push of a button.
Even highway patrol cars (that looks up data on all vehicle and driver from the central police database), are also enjoying the benefits of mobile computing.
Mobile computing is changing all the time; size, energy consumption and features improvement. Mobile computing has one common feature - they all have an independent source of energy.

Mobility is the ability to have a continuity regardless of location or time. For example the ability to send email from your email account at the office or answering an email while we travel by train at the end of the day home.

A partial list of features of mobility are:
Reading and writing emails from anywhere at any time.
Syncing data to a variety of places (photograph taken on the phone can be transferred to the personal computer automatically without physically lisiting the office).
Updating or changing meeting schedules and contact details.
Updating customer sales information from anywhere - products and prices.
