I. Introduction
The purpose of this paper is to investigate the evolution of and current trends in improving system performance with respect to RISC, pipelining, cache memory, and virtual memory.
II. Reduced Instruction Set Computing (RISC)
Reduced Instruction Set Computing also known as RISC is a type of microprocessor architecture. It is a CPU design strategy. The purpose of RISC was for design simplification. It increases the number of executed instructions thus increasing the CPU performance. (Joy)
The RISC design was first proposed and implemented in the 1960s and has been constantly evolving. Since the late 1980’s, RISC has been more than doubling its performance every year and half. The RISC industry, which includes IBM and Sun Microsystems, is ever expanding with the focus on the speed of executing instructions per second along with the evolution of the computer industry. (Joy)
III. Pipelining
One characteristic of RISC processors is pipelining. With pipelining, instructions are able to be executed in a shorter period of time. The first step in pipelining is to find the instructions, then read the registers, decode the instructions, execute the instruction, access the data memory operands, and then load the results into the register. There are three different types of pipelines: graphic pipelines, instruction pipelines, and software pipelines. (Martin)
Pipeline processors first started being designed in the 1980’s by IBM. In the late 1980’s pipeline processors were development with a parallel programming concept. This concept allows tasks to be executed in…...

Evolution of Computer Applications & Architecture

...Evolution of Computer Applications and Architecture By Ken Jacobi, Computer Architecture (IT-501) In discussing the evolution of computer architecture, we find that there are many angles on how people tend to view things. Some will take consideration in how things have changed over the last few years. Others will take a stronger look at the direction of where they believe technology is going. A third focus is in regards to the unexpected mistakes that people have made. In conjunction with the past, how can these mistakes be avoided in the coming future and evolution of technology; both for equal and competitive reasons. In part with this, we can turn to the very basic view about what makes a good design. Many architectural topics once began with the idea that if you build something and develop it correctly, change is not something one should expect. If it’s developed right the first time then you don’t have to change it. In this successful strive, people have come to the underlying conclusion that this is a very unrealistic position to be. A very good place to stress the relevance here is by dating back to the start of an exciting architectural turn of events that have gotten us to where we now are: the birth of modern computing. Many will say that this “landmark” of progress has lead to an evolutional launch that we constantly live within. It’s safe to say that these embarking events once began somewhere amongst the early 1970s. Coming out of...

...Final Project: Expository Essay Samantha A. 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...

Computer Evolution

...The History of Computers Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past. The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations...

...Chapter 1 The Problem and its Settings Background of the study As we move into the 21st century, technology has greatly improved and has become better. It is continuously growing and changing in many aspects until now. It makes the people’s life easier than the usual and is greatly helpful and useful especially to the students. Technology invented gadgets like computers and laptops that students can use in their studies. These gadgets changed how students learn, process and obtain new or old information. These can also use when it comes to finishing their task and completing their school works because students can freely visit many educational websites. Students can also play educational games, which can help them improve their critical thinking and problem-solving skills. However, technology has also negative effects like other things. Like computers, instead of using it for research purposes, students tend to use it for playing games like DOTA and Couter Strike. Students also use it for just viewing or signing in their social networking pages. Computer is a factor that distracts or steals away the attention or the focus of the students in their studies. Students abuse the power of technologies. Computer technology has positive and negative effects in the lifestyle of the students. Computer were invented to help students and not the be abused by the students which brings negative effects. But, majority of the results that were gathered presents that most students...

...Computer technology is advancing at a rapid rate, causing the diversity and availability of assistive technology computer resources to have a tremendous impact for special education students across the United States. Assistive technology provides an opportunity for students with physical, emotional, and mental disabilities to acquire universal access to tools and opportunities for learning. Despite studies showing the benefits of assistive technology, many school districts fail to achieve the fullest potential that assistive technology can offer. This paper will define assistive technology, identify several obstacles of effective implementation, and present various approaches to overcoming those obstacles.  Assistive technology is defined as "any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that issued to increase, maintain, or improve functional capabilities of individuals with disabilities" (Individuals with Disabilities Education Act, 1997). “Is society too dependent on technology?” Tom thought to himself as he drove to Colorado. He was on a family trip to visit his parents. It was a long trip and he had never been there before so he decided to use his navigation system to get there. He typed in his destination and headed to Colorado. On the way, his four-year-old son threw a juice cup, which spilled all over the navigation system. He did not think he would need a map, and now his family and he are...

...Computer Technology Being a kid sitting around with your friends, there was always that one person this said, do you think this will ever happened? When I grow up all I will have to do will say door open to get in my house, everything else will be done for me. now, much to my surprise this day has now arrived. The arrival and utilization of computers in today's world is absolutely unbelievable. Things can be done with computers that could have never been done in the past. we have security systems that don't need keys, cell phones that could go on line, and receptionists are now virtually unknown due to automated voice systems. the question that everyone wants to know is, our we too dependent on computers, and what will happen when they fail us? this is an idea that nobody really likes to discuss. Going further in-depth with this idea, what have computers done to the business world. many people feel it has enhanced businesses of today's society, others feel it has ruined them. there now companies being run by very few workers due to fully automated systems, systems that need one operator a and it can produce more than that of 15 to 20 a lot of cases. what this does the company's is forces them to put new technological advances in their budget to keep up with competition and be more cost effective. This is exactly why the technology is there, to get one step ahead of the competition, and to produce more product, more often. Integrating computers into assembly...

Evolution of Computer

...Background of the study The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of time,and each gave us either a new and improved computer or an improvement to the existing computer. First generation: 1937 – 1946 - In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. It was called the Atanasoff-Berry Computer (ABC). In 1943 an electronic computer name the Colossus was built for the military. Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built. It is said that this computer weighed 30 tons, and had 18,000 vacuum tubes which was used for processing. When this computer was turned on for the first time lights dim in sections of Philadelphia. Computers of this generation could only perform single task, and they had no operating system. Second generation: 1947 – 1962 - This generation of computers used transistors instead of vacuum tubes which were more reliable. In 1951 the first computer for commercial use was introduced to the public; the Universal Automatic Computer (UNIVAC 1). In 1953 the International Business Machine...

...Rhubes Severe Computer Technology Have you ever heard of the expression “necessary evil?” If it is evil, how can it be necessary? Well, there are some things that are necessary but not necessarily easy. People sometimes call “evil” the things that they find difficult or complicated. Thus, a “necessary evil” may be a thing that needs to be done for a greater good but that it may not be easy at first. The incursion of technology and computers in our everyday lives seems to be one of those “necessary evils” that we all have to deal with at one time or another. Today, technology is an integral part of schools in America. Teachers need to learn to use technology in the classroom in order to teach. Children become acquainted with technology in a safe learning environment with their teachers at school. Students are also expected to learn to use computers and interact with some educational software. The child’s homework often includes reports, research and or presentations using technology. Since children become some kind of experts with computers and interact with a variety of software at an early age, they see computers a little less challenging than an adult with little experience in computers. Technology has also made its place among the needful things to have at home. Parents often times feel the need to provide the technology that the child requires in order to do homework and to help the child study. That way, parents end up learning the technology first in order...

...Ever-changing Technology Technology is always revolutionizing. Teachers make adjustments to these technology changes in order to allow their students to learn better. Does technology really make kids learn more or keeps their attention longer? What makes learning better for students? Researchers in this field has gone into the depths of what students prefer and what keeps them interested in the class. As we all know, technology escalates every time we blink our eyes. It will always be growing and one day we all will have to adapt to it. From calculators to computers to tablets, and now even robots, life inside the classroom is revolutionizing. In today’s world we do not see it as much, but in the future we will know it all started with us. Children nowadays see technology as a new way of life. Everything seems to evolve around it. According to “Laptop Programs for Schools”, states that schools with laptop programs see an increased students’ engagement with academic work and school, improve technology skills, and have positive effects on students' writing. Many believe that leaning from technology can have many negative effects, but most surveys and experiments that people conduct can only see positive outcomes. The future of technology will definitely be a crucial part of the future of education. Many of the ideas and thoughts about future technology in the classroom are already being put to test and becoming true. Many big named corporations and leaders are...

From the invention of the wheel to the Internet, technology has been a great factor on the way our civilization has grown. With more and more technological advances just around the corner, our civilization will continue to grow faster and faster than ever before. Computers make life easier for people every day. They help us to do tasks quicker and communicate with friends and family with the click on a button. Computers play a significant role in the school system as well. They help students to learn more efficiently and help them do their work. Computers offer the Internet which helps students research information for projects they may have. School computers also offer programs which can help anyone learn. An example of this is the program All the Right Type. This program helps students as well as teachers, to learn how to type faster and more efficiently. Also there are other programs which younger students can go on to help them with developing and reinforcing their math skills and reading skills. Programs like Math Circus and matching the word with the picture. Programs like these make it easy to understand and use computers, yet it also makes learning fun. Computers also make writing and doing homework easier to complete. With spell check and other spelling tools, it makes it easier and faster to complete work. This is because you are not spending all your time going through...
