INFS 211: Introduction to Information Technology Session 10 – Mobile Computing Lecturer: Dr. Ebenezer Ankrah, Dept. of Information Studies Contact Information: eankrah@ug.edu.gh Session Overview Just 30 years ago, the idea of a powerful personal computer that could fit on a desktop was a dream. Today, you can carry computers around in your backpack; fit them in your pocket and even incorporate them into your clothes. Mobile computing devices – portable electronic tools such as cell phones, PDA/Smart phones, portable media players and notebooks are dramatically changing our day to day lives, allowing us to communicate with others, remain productive and access a wide array of information no matter where we are. This section will cover the advantages and limitations of mobile computing and the various types of mobile computing devices. Slide 2 Session Overview At the end of the session, the student will Understand the advantages and limitations of mobile computing Be able to distinguished between the various mobile computing devices Understand how cell phone components resemble a traditional computer and how they work Slide 3 Session Outline The key topics to be covered in the session are as follows: Mobile Computing Types of Mobile Computing Devices Applications of Mobile Computing Limitations of Mobile Computing Slide 4 Reading List http://www.encyclopedia.com/topic/Mobile_Computing.aspx http://www.doc.ic.ac.uk/~nd/surprise_96/journal/vol4/vk5/report.html http://www.wisegeek.com/how-has-the-source-of-computing-power-changed-over-time.htm Alan, E., Kendall, M., & Poatsy, M.

Topic One Slide 6 Mobile Computing Mobile computing refers to the use of small and portable computing devices in wireless enabled networks that provide wireless connections. Mobile Computing is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link. The main concept involves Mobile communication, Mobile hardware and Mobile software. Slide 7 Mobile Computing As the internet becomes increasingly popular, a new paradigm is being developed in networked computing known as nomadic computing or mobile computing. Mobile computing aims to provide a network infrastructure and corresponding terminal capability to perform all desktop-like computing functions seamlessly at any place or time, even while the terminal is moving. Slide 8 Mobile Computing This means that anytime and anywhere, a user would be able to browse the web, check e-mail, play digital music, and perform all other computing activities without having to
