Comparing DEC Alpha and Intel Pentium Processors The main difference between the architectures of Digital Equipment Corporation's (DEC) Alpha and Intel's Pentium processors are the instruction sets. In this paper I intend on defining both RISC and CISC processors. In doing this I will be comparing DEC's Alpha 21164 (a microprocessor that implements the Alpha architecture) and also Intel's Pentium processors (from the Pentium-R through the Pentium II). Reduced Instruction Set Computing or RISC

Yellow Fever is a viral infection that is caused from the bite of an infected female mosquito, they are mainly found in areas of Africa and South America. There are three main types of the Yellow Fever virus: Sylvatic yellow fever, Intermediate yellow fever, and Urban yellow fever. Sylvatic yellow fever also known as jungle yellow fever is started by mosquitoes breeding in tree holes in areas, such as banana plantations; monkeys become infected when they are bitten by an infected mosquito, it continues
Topic The Morris Worm changed the world of computer security at a time when it was merely an afterthought. In 1988, when the worm was released, system administrators were confronted with a cyber-attack that they never expected or saw before. Although the level of damage that was caused by the Morris Worm was caused by an out of control college student’s project, the individual responsible, Robert Morris, faced criminal charges. Robert Morris was a first year graduate student at Cornell in his first
Introduction This paper discusses about the historical event that takes place within the operating system and their recent development and progression. Therefore it is essential to have a clear comprehension on the operating system that is still accessible to recognize its fundamental strengths and weaknesses. Hence, it is imperative to evaluate the operating system we are reviewing to distinguish between them. Meanwhile, this paper also inspects on the difference between the open source and proprietary

These computers would be programmed (usually in FORTRAN) and the information passed onto the Cray. The results would then be transfered back to the front end computers.

“UNIX was the first operating system designed to run on ‘dissimilar’ computers by converting most hardware specific commands in machine language into an independent programming language called ‘C ’” . UNIX was the basis of AT&T’s telephone system and the government’s wide area network system. Then it became the basis of communication between engineers and scientists, and eventually the basis of communication for everyone worldwide. It has held this remarkable spot since 1969. However, in the 1990s
Vaccines and You As I walked into my medical building today, I made note of a sign in the front door. “Measles has been recorded in California, Utah, and Colorado. Please be aware of the symptoms, and vaccinate your children.” If you didn't already know, measles is a very contagious viral disease that is marked by a fever and rash. It’s most prevalent in children and can be dangerous, even fatal. However, in 1960 a vaccine was developed that could prevent the disease before it happens. Since then
Expert Systems: The Past, Present and Future of Knowledge-based Systems Expert Systems were invented as a way to decrease the reliance by corporations on human "experts" -- people who apply reasoning and experience to make judgements in a specific field, such as medicine, insurance underwriting or the operation of a power-plant. Hence, an expert system should include a database of facts and a way of reasoning about them. In many, but not all, applications it is also helpful to have a way for
Are powerful, special-purpose computers. They were originally viewed as small mainframes - hence the prefix 'mini'. However, they have become increasingly powerful and have replaced mainframes for many functions. Examples include Digital Equipment's VAX machines and IBM's AS/400s. They typically cost in the $100,000s. Tasks minicomputers might be used for include: Plant control: Many industrial plants require a central computing facility to collect data from various sensors and then to act accordingly
Would you intentionally put your children in harm’s way? Of course not! Parents would never want their children to suffer, especially if there was a way to protect them. However, some parents put their children at risk for deadly diseases by refusing to vaccinate them. If your children are not properly vaccinated, then they are vulnerable to harmful diseases. Vaccines have eliminated many diseases and saved millions of lives. There is currently no federal law that requires vaccination. However, if
Vaccinations have become a huge topic in the mainstream media in recent years; Governor Jerry Brown signed bill SB277 on June 30th, 2015 which removes religious or philosophical exemptions, leaving only medical exemptions applicable for school children to attend school. This leads to the heated debate over whether parents/families should have the right to refuse vaccinations or should all parents of children have to comply with a one-size-fits all vaccine mandated schedule to attend school? If we
The Anti-Vax Issue According to World Book Advanced Encyclopedia, immunization is defined as the process of protecting the body against disease by means of vaccines or serums (Hinman). While medical science backs up the efficiency and necessity of vaccines, within the past decade, a rise in parents disbelieving the medical community and neglecting to immunize their children has occurred. This “fear of vaccines” is nothing new, but with the ever-increasing safety of vaccines, the benefits of
Same as any other area in computer science, viruses become a great deal indeed throughout the years. Return to the origin of computer viruses, although there were no viruses or worms developed, Mathematician John Von Neumann had described the theories of self-replicating programs in 1949. In 1971, Bob Thomas has developed “The Creeper Virus”. It was an experimental self-replicating program. It infected DEC PDP-10 Computers to run the TENEX Operating System. The Reaper program was later developed

Making coffee production climate smart and climate friendly involves introducing trees in plantations, optimizing fertilizers production and use, and reducing emissions from fermentations and wastewater production. Vax Rkxoort et al discovered that commercial polyculture systems, in which leguminous trees and fruits trees are grown together with coffee plants, segregate substantial amounts of carbon, compared to shaded and unshaded monocultures and also make relatively

In 1978 Bill Joy and his UNIX team received funding from the federal government to devise software for the VAX computer that would allow it to link to the ARPANET network, a precursor of the internet. His team beat DEC's own programmers in the bid to work for the Pentagon's Defense Advanced Projects Agency. In 1982, Bill Joy was recruited by entrepreneur Scott

Even during prehistoric times man has relied on different types of machine to improve life and make it easier. Throughout time man has improving robotics into the machines that we have today.

Intermission Riff The song that I chose to write about is Intermission Riff composed by Ray Wetzel and originally recorded by Stan Kenton and his Orchestra. I have chosen three of my favorites versions and performances of this song. The first one is an original recording by Stan Kenton and his orchestra performing live in London in 1972. Another version is specifically on of my favorites because it incorporates voices and lyrics to the song. The final version I will discuss is one played by a
