Medina University of Phoenix Final Project: Expository Essay Computer technology has developed tremendously over the decades and centuries to become so modern in every aspect including education and personal leisure. It is breath taking to see how modernized out computer technology is today as opposed to the limited computer technology that was available in history. The changes that have occurred over history to today will be discussed and focused upon in this essay. The Mechanical Era: Early Computing Devices The Abacus The abacus was the first machine to be used computational science. It is considered to be the first computer. This machine was inspired by one of Charles Babbage’s designs. The abacus could process 15 digit numbers and calculate fourth-order differences. In 1885 the machine won gold medal at an exhibition in Paris and also helped calculate the orbit of mars! The abacus is still in use today. Imagine that a computing device from centuries ago still being used to this day! Charles Babbage Charles Babbage was an English mathematician, philosopher, inventor and mechanical engineer ("Charles Babbage", 2012). Babbage is known to have invented the first programmable computer. As stated earlier his design inspired the abacus and other complex designs. He won the Gold Medal of the Royal Astronomical Society for inventing an engine for calculating mathematical and astronomical tables. Babbage was also Lucasian Professor...

...not only state and national boundaries, but the international boundaries as well. At the Tenth United Nations Congress on the Prevention of Crime and Treatment of Offenders, in a workshop devoted to the issues of crimes related to computer networks, cybercrime was broken into two categories and defined thus: * In a narrow sense, the term cyber crime has been defined as any illegal behavior directed by means of electronic operations that target the security of computer systems and the data processed by them. * In the broader sense, cyber crime has been defined as any illegal behavior committed by means of, or in relation to, a computer system or network, including such crimes as illegal possession [and] offering or distributing information by means of a computer system or network. The extent of cyber crime is so vast and complicated that an act which may be crime in one nation may not be so in another. Some of the basic examples of cyber crime are unauthorized access, damage to computer data and program, computer sabotage, unauthorized interception of communications, computer espionage, etc. Thus, the fact is that there can be no exhaustive and complete definition of this term, as it is so wide that its arena increases every day. Once computer had been regarded as a boon for the human world, but today, there has been a change in the outlook. To the utter disgrace, India had been ignorant of such a law as cyber law until the last decade. It was only when there was...

...Parker Devry University MDD 410 September 23, 2012 Professor Kimberley Martin A New 3-D Innovation: The Leap “The distance between you and the virtual world is about to get smaller.” (Trinh, 2012). Leap Motion is about to release a new device that will change how we control and interact with our computers. The device is called The Leap and it is a 3-D motion tracking device. It can be connected to a computer or any other computing device and the user can use the gestures of their hands instead of keyboard or mouse. It is kind of like the X-box Kinect but “more powerful, more accurate, smaller, cheaper, and just more impressive.” (Pierce, 2012). The Leap is set for public release in February of 2013. Leap Motion has set the price at $69.99. The device is currently about the size of an usb flash drive but could end up being as small as a dime before being released to the public (Pierce, 2012). It can track your movement to 0.01 mm (Pierce, 2012). Also it can track all ten of your fingers and thumbs individually as well as anything you may have in your hands. It creates a 3-D workspace of about eight cubic feet, however multiple devices can be linked together to create a bigger space. According to David Pierce on the website www.theverge.com, “VGA camera sensors within the device create the space”. The Leap can open up the possibilities for many different uses. The most basic thing it does is virtually turn any computer type display into a touch screen. However you don’t...

...affect marketing for a particular product or service. These five are economic, technological, regulatory, competitive, and social. Depending on the industry, some or all may affect the marketing strategies used by that particular industry. The industry chosen is the computer manufacturing industry. Below are three chosen environmental forces that impact this industry. The first market force that impacts the computer industry is economic and the decline of consumer spending. Since the economic downturn in 2007, consumers tightened their wallets and began to spend less than what they had been spending in prior years (Hartley, Kerin, & Rudelius, 2013, p. 73). This led to slumped sales within the computer industry. Several other markets experienced this slump, and it primarily occurred from consumers judging their purchases on necessity instead of desire. In addition, computer parts such as hard drives, motherboards, peripherals and more were already experiencing a drop in price over the last ten years. Currently, the prices for manufacturer parts dropped to 50 percent (Hoover’s INC, 2012, ch. 11). As the economy slowly heals, consumers are still wary about spending excess money (Chappell, 2011). The computer parts industry and others rely on consumer spending in order to make a...

...Accounting Information Systems July 28, 2012 Summary of United States vs. Bo Zhang Bo Zhang, a Chinese computer program, was a contract employee assigned to the Federal Reserve Bank of New York (FRBNY), between May 2011 and August 11, 2011, to work on further developing a specific portion of the Government Wide Accounting program (GWA) source code (FBI, 2012). Mr. Zhang was not a United States citizen and was here on a VISA. The United States had spent approximately $9.5 million to develop the GWA code. The FRBNY was given the task of moving the Government Wide Accounting program, developed to help track the billions of dollars the United States government transfers daily, from an antiquated IBM mainframe computer to the Internet, according to a person familiar with the project (Chicago Tribune, 2012). In the summer of 2011, Zhang stole the GWA Code and, without authorization from FRBNY, copied it onto his hard drive at the FRBNY and an FRBNY-owned external hard drive. He then transferred the code to his private office computer, his home computer, and his personal laptop (FBI, 2012). Zhang used the GWA code to access the government system and submit fraudulent documentation to immigration authorities to help foreign nationals obtain visas to enter and work in the United States. Zhang falsely represented to immigration authorities that certain foreign nationals worked full-time for his computer training business. At least one individual...

History : Flame was discovered first in May 2012 by MAHER Center of Iranian National CERT, Kaspersky Lab and CrySyS Lab (Laboratory of Cryptography and System Security) of the Budapest University of Technology and Economics. (Wikipedia, 2012) It has discovered that a module from the early 2009-version of Stuxnet, known as “Resource 207,” was actually a Flame plugin.This means that when the Stuxnet worm was created in the beginning of 2009, the Flame platform already existed, and that in 2009, the source code of at least one module of Flame was used in Stuxnet. (About Us: Kaspersky, 2012) Key Features: 1. Size—20MB, which is huge for a malware program. 2. The malware uses five different encryption methods and a SQlite database to store structured information. 3. It attacks the computers which are using the Microsoft Windows Operating System. 4.
