General Information

What is mobile programming?
It is programming mobile devices
Why we need this ucking course group?
Because mobile devices differs in some ways from
the desktop devices (called computers or
workstations)
Lower performance (we need tricks to get things
done rapidly)
Less memory (we need algorithms that consume less
memory)
Network capasity is smaller
Lower data rates
Much larger latencies
Why we are here?
We must learn those tricks in order to be a
competent mobile (device) programmer
This course group (Specialization Studies in
Mobile Programming) is created to help you to be
a programmer who can create software for mobile
devices

General information (HW)

Mobile technology has been developed extremely
rapidly in recent times
Computation power of microprocessor is increasing
steadily (according to the Moores observation)
We can build smaller and higher-speed components
Processing power is doubled in every year
Memory capasity is doubled in a year and a half
Performance of the mobile devices is roughly ten
years back from the desktop devices
This means that applications that were possible
ten years ago are now possible in mobile devices

4
General information (DataComm)

Data transmission rates are increasing
Optical signaling
Costs of wireless devices are going down
And data transmission rates ate increasing also
in wireless area
More and more devices are connected together
When we talk about the connections itself, we
call the system as network
When we are more concerned what can be done with
these connected devices we call the system as web

5
General information (SW)

Current trandlines in software developments are
Effective software component reuse (functions,
objects, containers, etc.)
Mastering the distribution of applications(also
in diverse hardware environments)
Because we have multiple devices in a network (or
web), building applications are more demanding
(than in single device environment)
Distributing technology is more and more
important
Ajax (Asynchronous JavaScript and XML) is one
cross-platform technique usable on many different
operating systems, computer architectures, and
Web browsers
it is based on open standards such as JavaScript
and XML, together with open source
implementations of other required technologies.
