Mobile computing allows users to access information and computing resources while mobile. It began in 1981 with the Osborne 1 portable microcomputer. Today's mobile devices like smartphones and tablets use wireless networks to access the internet and cloud-based apps and data from anywhere. They utilize mobile operating systems like Android and iOS and rely on technologies like 4G LTE for high-speed data connectivity on the go. The future of mobile computing may include more powerful devices using nanotechnology, as well as virtual assistants accessible through natural language commands to help users remotely.

2. So, What is Mobile Computing?
Mobile computing is human–computer interaction by
which a computer is expected to be used normally
during transportation or Simply “Computing on the
Go”.
With an Objective to Display, collect, and transfer
information from a mobile device to an information
system using one or a combination of various data
transfer methods.

3. How did it all start?
It all started in 3 april 1981 when…
The Osborne 1 was the first commercially
successful portable microcomputer, released by
Osborne Computer Corporation. It weighed 10.7
kg (23.5 lb), and ran the then-popular CP/M 2.2
operating system. The computer shipped with a
large bundle of software that was almost
equivalent in value to the machine itself.

4. The revolution that took place in the
evolution
Leading computer manufacturers of that time invested more money on
their research, making the portable computers more compact and
powerful. After just 33 years of evolution, we today have..

5. What does mobile computing require?
• A Mobile Computing Device (MCD)
• A Wireless network or data connection
• An Information System Component
• Data or Objective to act on

6. Mobile Computing Device (MCD)
Mobile computing devices include the following…
• Laptops
• Netbooks
• Smart Phones
• Tablets
• Wearable Computers

7. How are they connected?
In the present Mobile computing has become more dependent on
Communication.
Wireless data connections used in mobile computing take three general
forms,
• 2G – GPRS/EDGE/CDMA
• 3G – WCDMA/HSPA
• 4G – HSPA+/LTE/LTE-advanced

8. Limitations of wireless Network access still threatens the future of
Mobile Computing.
Mobile Internet access is generally slower than direct cable
connections, using technologies such as GPRS and EDGE, and more
recently HSDPA and HSUPA 3G and 4G networks. These networks are
usually available within range of commercial cell phone towers. Higher
speed wireless LANs are inexpensive but have very limited range.

9. Requirements of a MCD
• Powerful hardware
• Power efficiency
• Storage
• Connectivity
• Large power reserve
• Reliable software
• Durability

10. Technology used in Laptops and
Netbooks
• These portable version of computers use the same technology as
used by desktops.
• They are less powerful than desktops but, they posses a built in
battery backup enabling the user to use the machine on the go
without any external power sources.
• Laptops also come withWLAN connectivity enabling the user to
connect to a network, some even have built in wireless modems that
support 3G and 4G networks for connectivity on the go.
• They have a compact chipset with the compact version of processor
chips as used in Desktops.

11. Smartphones and Tablets
• The Hardware of a Smartphone
• Smartphones run on 100-2224 MHz processors (single to Quad
cored). These processors could not come close to powering a
desktop computer, but for the somewhat limited tasks that a
smartphone performs those processors are very effective.
• The processors used are ARM processors, which have tens of
megabytes of onboard memory. MP3 players, routers, printers, and
other technologies use these processors.

12. Mobile Operating System
• Smartphones software is arranged as a “stack”.
• The software stack contains:
• Application suite- used for simple applications like menu screens and
message inboxes
• Application execution environment- application programming interfaces,
instituted recently so tech-savvy phone-owners can create their own
programs
• User interface framework- deals with what is actually seen on the screen of
the phone
• Kernel- manages the hardware (drivers and management systems)
• Middleware- libraries of software that enable applications like security,
web browsing, and messaging

13. Operating Systems
There are many mobile operating systems.
• Java ME Platform
• Palm OS
• Symbian OS
• Linux OS
• Windows Mobile OS
• BlackBerry OS
• iPhone OS
• Google Android Platform

14. Wearable Computers
• Google Glass is a wearable computer
with an optical head-mounted display
(OHMD) that is being developed by
Google in the Project Glass research
and development project, with a
mission of producing a mass-market
ubiquitous computer. Google Glass
displays information in a smartphone-
like hands-free format, that can
communicate with the Internet via
natural language voice commands.

15. Future of mobile computing
• Better performance will be achieved if NanoTechnology is applied
into this field.
• Disaster detection can be improved.
• Remote computing can be used to access a virtual assistant (AI).
• Can be used to take care of the sick and aged people.
• Radical technology can me used to make MCDs more powerful and
reliable.
• Mobile cloud computing can be done to sync massive amounts of
data and provide free resources to the public.

16. Fiction into Future
• It is possible that near human intelligence can be achieved in
computers in the near future, But the mystery that’s waiting to be
revealed is that “Is it possible to take the AI with us everywhere?” say,
the fictional character JARVIS,Virtual Assistant of Iron Man.

17. Yes, It’s Possible
• The answer for that question lies in Mobile cloud computing
technology,There are indeed infinite possibilities out there we just
have to explore them.

and transform us.”
