1. Essay about Mobile Computing
Background and Introduction
The recent trend in mobile computing has led to a plethora of relatively inexpensive high power computing devices that can fit in a shirt pocket.
These new devices are capable of internet connectivity and are location aware, making this new technology both highly useful and just as dangerous
in the hands of malicious hackers. In November of 2009, the first iPhone virus was released. It was not malicious and only changed the user's
background picture. [1] This first worm was written as a proof of concept to warn of the potential dangers of viruses for mobile devices. The author
stated in a later interview with ABC his reasons for creating the virus: "I think to raise awareness for one, somebody with more...show more content...
Problem Statement Currently, there is no simple way to recover lost source code or analyze malicious code that can be run on mobile devices such as
the iPhone. The goal of this thesis is to develop techniques for static analysis of iPhone binaries to facilitate malicious code identification and recovery
of source code for software companies. Technical Approach
In "Reverse Compilation Techniques," [5] Cifuentes relates decompilation to the reverse of compilation. In compilation, thecompiler takes in a specific
High Level Language (HLL) and converts it to a corresponding Low Level Language (LLL), usually through some intermediate steps. With
decompilation the low level representation is converted back to a HLL representation. Cifuentes refers to the 3 stages as front–end, UDM and back
end. The UDM, or Universal Decompiling Machine, is a general format that any front end can generate and any back end can understand. Given a
perfect UDM, decompilation would simply be a matter of targeting the decompiler by writing a new front end or back end. However, "In practical
applications, this result is always limited by the generality of the intermediate language used."[5]. This thesis was written in 1994. Cifuentes' original
UDM did not consider object oriented programs (OOP) in its implementation. Since that time, new paradigms have emerged and OOP has become
highly prevalent. The concept of decompilation is often considered impossible since, during

2. Wireless Technology Essay
Wireless Technology
Wireless technology is an industry that has seen much growth and progress in the years following the inception of the internet and cell phones. Our
society has progressed to the point to where we can no longer function without this technology. Business, travel, and everyday life now are dependant
on wireless technology.
Wireless technology is just what its name implies, communicating or computing without wires and phone lines. Wireless technology uses a variety of
different devices such as desktop and laptop computers, personal digital assistants (PDA's), cell phones, and many others.
The major benefit of wireless technology to users is the immediate access it offers to resources. Whether it is...show more content...
Horizontal integration delivers benefits such as data mining, real–time transaction processing, and decision–support systems. Wireless data–translation
protocols allow contrasting devices to efficiently use information from all sources.
Wireless technology has also lead to the advent of PDA–cell phone hybrids called smart phones. The combination cell phone and organizer also has
Web access, email and messaging capabilities, an MP3 player, Bluetooth support, and a digital video camera.
PalmSource made wireless device–to–device communication more popular by putting an infrared port on every Palm OS handheld. From the advent
of the first Palm OS handhelds in 1995, the concept of "beaming" information became a norm in the business world. Business cards, applications, and
content began to move from one device to another with ease. PalmSource is now innovating again by pioneering Bluetooth in mobile devices such as
handhelds and cell phones.
Bluetooth is a cable–replacement technology for passing information between devices not unlike infrared. The advantage that Bluetooth has over
infrared is that devices using Bluetooth do not have to be pointed at one another, the distance between devices can be much greater, the speed of
transmission is much higher, and the data passed can be encrypted and
