Presented by: @Paul Kahoro

2. What is Computing?
Computingis anygoal-orientedactivity requiring, benefiting from algorithmic processes -e.g. throughcomputers. Computing includes designing, developing and building hardware and software systems; processing, structuring, and managing various kinds of information.
Thefieldofcomputingincludes:
•Computerengineering
•Softwareengineering
•Computerscience
•Informationsystems
•Mobiletechnology

4. Small computing is associated with mobility of hardware, data and software in computer applications. Information at any time, any place, and in any form. Whether in the office, at home or virtually any place on earth. Mobile computing is the use of computers in a non-static environment.
Nomadic, Ubiquitous Computing, Pervasive Computing, Internet of Things.

5. Forms of computing:
•Ubiquitous Computing
•Nomadic Computing
•Mobile Computing
•Pervasive Computing
•Invisible Computing
•Wireless Computing

6. What is ubiquitous Access?
Small Computing supportsUbiquitous computingwhich is a concept incomputer sciencewhere computing is made to appear everywhere and anywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format.

7. Forms of computing cont..
•Nomadic computing is the use of mobile computing technology to connect to the global Internet or use specific data resources from a stored location while moving around from one place to another.
•Mobile computingishuman–computer interactionby which acomputeris expected to be transported during normal usage. Mobile computing involvesmobile communication, mobile hardware, and mobile software. Communication issues include ad hoc and infrastructure networks as well as communication properties,protocols, data formats and concrete technologies.
•Pervasive computing is the growing trend towards embeddingmicroprocessorsin everyday objects so they can communicate information. The words pervasive and ubiquitous mean "existing everywhere."Pervasive computing devices are completely connected and constantly available.Pervasive computing relies on the convergence of wireless technologies, advanced electronics and the Internet.

10. Improved decision making:
Increased productivity and reduced costs
Improved customer relations
Advantages Of Small Computing
•The ability to collect, access and evaluate critical business information quickly and accurately means better decision making.
•Mobile computing can lead to increased individual productivity, increased sales per sales person, more service calls per repair person, less time spent by professionals on administrative work, and much more.
•Mobile computers gives your field worker the ability to answer customer questions, check order status and provide other services anytime their customers need them from wherever they happen to be.

11. Applications of Small Computing
Healthcare
e-Learning
Mobile banking, stocks,

12. Advances in Small Computing Technologies
•More computing power in smaller devices.
•Flat, lightweight displays with low power consumption.
•New user interfaces (due to smaller dimensions).
•More bandwidth per cubic meter.
•Multiple wireless interfaces: wireless LANs, wireless WANs, IRDA, Bluetooth etc.
•Battery/power improvements.

13. Challenges and Limitations
•Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently HSDPA and HSUPA 3G networks. These networks are usually available within range of commercial cell phone towers. Higher speed wireless LANs are inexpensive, but have very limited range
Insufficient bandwidth
•When working mobile one is dependent on public networks, requiring careful use of VPNs.
Security standards
•When a power outlet or portable generator is not available, mobile computers must rely entirely on battery power. Combined with the compact size of many mobile devices, this often means unusually expensive batteries must be used to obtain the necessary battery life.
Power consumption

14. Challenges and Limitations Cont…
•Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.
Transmission interferences
•More car accidents are related to drivers who were talking through a mobile device. Cell phones may interfere with sensitive medical devices. There are allegations that cell phone signals may cause health problems.
Potential health hazards
•Screens and keyboards tend to be small, which may make them harder to use. Alternate input methods such as speech or handwriting recognition require training
Human interface with device

15. Future of Small Computing
Mobile computing field is rapidly growing day by day. And the technologies used in Mobile computing is increasing rapidly.
In future we will see many amazing products of mobile comuting technology.
