Introduction

In a not so distant past, we had so many limitations to what we could do with computers and especially mobile devices like cell phones. Could you imagine 5 years ago being able to video conference from your phone that is small enough to fit in your pocket? I’m going to cover some of the technological advancements in mobile technology, as well as different Cpus and manufacturers in our ever so changing society.
In today’s society, technology moves at a very fast pace. So fast in fact, that a top of the line computer you buy today, could possibly, and more than likely be obsolete in a years’ time. You may have in fact bought a computer in 1998 for a mere $2200 that could have had a 450 MHz CPU, 128Mb ram, and an 8000Mb hard drive to say the least. Today that computer is basically useless compared to the advanced of today’s computers. A low-end computer today runs around $400. Technological advancement is at an all-time high.

Findings

The brain of a computer is called the CPU or central processing unit. In the past this varied in size, pin configuration, speed and shape, depending on its use and manufacturer. As years have gone by, these Cpu’s have become more sophisticated to say the least. We are now able to not only make them smaller and faster, but now we are able to incorporate more than one Cpu on a single chip. This is what is called a multi-core processor. It’s like taking multiple computers and harnessing the power into a single computer. Why might you ask do we need the multi-core processor? As our society grows, so does the need for more intense programs. We require more in-depth and more efficient applications. The need has arisen for things to be done much faster and more precise. The ability to work on multiple programs at once (also known as multi-tasking) has become an everyday occurrence in the workplace. We have the need to be more productive and more efficient. This alone fuels the need for more productive Cpu’s. A single-core Cpu has speed limitations. There is only so much it can do. So engineers designed the multi-core cpu. With these they achieve the much needed speed and power for power hungry programs. With these advancements also come drawbacks. Heat is a very big issue, along with power consumption. As most businesses have gone to laptops for mobility, these two problems had to be dealt with. The answer to this problem has somewhat been rectified by the use of new types of architectures. Architecture is how the chip is put together. Not only different types of materials are used, but the way the circuits are layered on the chip. Multi-core processing has become the mainstream in Cpu designs.

Intel and AMD are the two mainstream manufactures of Cpu’s. Intel produces many different flavors of multicore processors: Pentium D is used in desktop computers, while their Core 2 Duo is used in both desktop computers as well as in laptops. AMD on the other hand has the Athlon series Cpus in the desktop line up, and the Turion series processors for the laptop series. Each of these chips have their own characteristics that make them fit each application. The laptop processors are lower power consumption and less heat dissipation, while the desktop chips aren’t as delicate. The need for lower power consumption saves valuable battery life, while the lower heat dissipation help with longevity. There are many, many different styles and brands other than the ones mentioned. There have been a couple other manufactures of Cpu’s in the past, but they faded along the way, until now. With technology at its present state, we are able to incorporate a few of these processors into mobile devices such as cell phones, as well as tablet computers. These devices are much more portable than even laptops, making them the new wave of must haves! Mobile devices perform a wide variety of tasks such as Web browsing, video playback, mobile gaming, SMS text messaging, and location-based services. Due to the growth in the availability of high speed mobile and Wi-Fi networks, mobile devices will also be used for various performance-intensive tasks that were previously handled by traditional PCs. The next generation of smartphones (called “Super phones”) and tablets will be used for a wide variety of tasks such as playback of high definition 1080p videos, Adobe Flash-based online gaming,
Flash-based streaming high definition videos, visually rich gaming, video editing, simultaneous
HD video downloads, encode and uploads, and real-time HD video conferencing. Yes you heard me, the ability to video conference on your smartphone! What an innovation! No more need to be in the same office, we can now conference face-to-face with our phones. Imagine talking to someone in China from our town of Owosso, Michigan by not only voice but seeing them too. No more impersonal phone conversations. This is made possible by the new generation of mobile processors. The current generation of mobile processors is not designed to deal with this tidal wave of high performance use cases. The quality of experience on devices based on single core CPUs rapidly degrades when users run several applications concurrently, or run performance intensive applications such as games, video conferencing, video editing, and more. In order to improve CPU performance, engineers employ several techniques, such as using faster and smaller semiconductor processes, increasing core operating frequency and voltage, using larger cores, and using larger on-die caches. Even though engineers may be able to squeeze out higher performance by increasing frequency and voltage, the performance increase would drastically reduce battery life. In addition, processors that consume higher power would require larger cooling solutions resulting in an undesired expansion in device size. Therefore, increasing the operating frequency of the processor to meet the ever-increasing performance requirements of mobile applications is not a viable solution for the long run. To satisfy the rapidly growing demand for performance and form factor sleekness in mobile devices, the industry has begun to adopt newer technologies such as Symmetrical
Multiprocessing and Heterogeneous Multi-core computing. NVIDIA Tegra is the world’s most advanced mobile processor built from the ground up as a heterogeneous multi-core SoC
(System-On-a-Chip) architecture with two ARM Cortex A9 CPU cores and several other purpose-built cores to handle specialized tasks such as audio, video, and graphics. Purpose-built cores require fewer transistors, operate at lower frequencies, deliver higher performance, and consume much lower power than general purpose processing cores for tasks such as audio, video, and graphics processing. Nvidia has been a long time manufacture of video cards and computer chipsets, but this is a giant leap for them becoming the first dual-core mobile processor manufacturer. I have firsthand experience with this new Cpu as I own a smartphone that contains this technology, and it has been a very impressive experience working with it. To think, I have more processing power in my hand than even some desktop computers! It handles multi-tasking with ease. I’m able to surf the web, watch a video, even record HD video all from the palm of my hand. The videos it takes are amazing to say the least! Clarity, quality, sound, web-surfing, conferencing, and the vast amount of free apps available compound the user experience only available due to this tiny little chip inside a mobile device not much bigger than a credit card.

Conclusion

In conclusion, before multicore processors the performance increase from generation to generation was easy to see, an increase in frequency. This model broke when the high frequencies caused processors to run at speeds that caused increased power consumption and heat dissipation at detrimental levels. Adding multiple cores within a processor gave the solution of running at lower frequencies, but added interesting new problems. Multicore processors are an important innovation in the microprocessor timeline. With skilled programmers capable of writing parallelized applications multicore efficiency could be increased dramatically. In years to come we will see much in the way of improvements to these systems. These improvements will provide faster programs and a better computing experience. The world of multi-core processing is just in the beginning stages; just imagine where we will be in 5 years….10 years! Just think of the endless possibilities we have just over the horizon. Things we do with this technology today is just a preview of what is to come.…...

...Running head: Technology and Management Technology and Management The latest technology can be seen on sales floor and in offices. Innovations in technology have improved operations at companies of all sizes and helped turn small local businesses into global businesses. Coming from the state of Maine, a retail store Laurie Rodriguez used to work had more than 200 retail stores in the New England area. Working in retail, one must expect the same from each store and to mainly focus on Customer Service. The use of wireless phones has become like a lifeline as much as a necessity because salespeople continually call to know when to deliver products. There is a wireless service that is installed in all stores and is at the point of sale registers, without these, manual is no longer among options, customers want to be out fast and efficiently, these point of sale registers allow for the effectiveness of the customer’s wish, standing in line at a register does not increase sales, or improve the business, but only decreases a little. These devices are lifelines when the store is overrun with shoppers, which seems to be just about every day. Staying in touch when on the road and responding to customer inquiries in a timely manner should be a must, when using cell phones, e-mail, text messaging and social networking’s and other advances in communication will keep small businesses connected to their customer bases and improve communication within the company (Kooser, 2011).......

...Technology has made life easier for people and it is now becoming something that people rely on too much. In today’s world technology is seen everywhere you go, you can see it in a workplace, schools, public places and in our homes. Technology is a great thing as long as people remember to use it as a tool and not a way of life. Because people rely on technology, it has caused problem like loss of work, vehicle accidents, and lack of proper communication. People should know how to live without fully relying on technology and sadly, not many do know how to live without it. People will argue that technology is the future and that people need to know how to use it to live. Workplaces will argue that technology has improved productivity and reduced costs. Schools will argue that technology has made learning easier for most students and it is something they need to learn to be ready for life outside of school. Most people will just simply argue that they cannot live without technology. These are all good points and yes because of technology, we have been able to get more work done in less time. Sure technology can do the work faster and with fewer mistakes as a person and learning how to use technology is something that everyone needs to know. However, we have relied too much on technology and the question should not be can you live without technology, the question should be, do you know how to live without technology. Today’s jobs mostly run on technology and less by humans....

With todays technology it makes it very easy to relive past conversations and go back to recorded moments. With modern day advances, individuals hold the ability to be able to capture a moment at anytime and share it around the world with whom they choose. We are also able to play games, entertain ourselves, see others, and talk to our friends at a single push of a button within just a couple of minutes. Technology continues to grow within industries making it easier to communicate and stay organized all due to a tiny handheld gadget. The better the technology the easier it is for people to stay connected with each other. Although there have been several groundbreaking inventions in history, it is noticed that the cell-phone has had a noticeable impact on society, especially among todays youth. With children now gaining access to a variety of these devices it is apparent that many lack basic elements in communicating. With a participant group of roughly twenty-five people, each student was asked to perform an “E-Fast” where the group would go certain amount of time restricting themselves from different forms of technology. Under the “E-Fast” and outside research it was noted that unlimited access to texting, and social media sights could result in a great amount of miscommunication between users. Both......

...Technology: It’s Effect on Our Youth Growing up I remember playing outside all day, enjoying the outdoors, and riding bikes down the dirt roads, trying to find some new adventure to get into. Looking around now, I notice teenagers glued to their phones when they are out eating, walking around and even while driving. It seems like a lot has changed since I was a child. Technological advances have made our way of life easier by making communication faster than ever before, improving production rates, and making it easier to access information. However, with the good also comes the bad. I have noticed an increase in the time children spend inside, as opposed to outdoors, the changes in behavior of children and teenagers, and the decline in personal interaction. I believe that technology, if not used in moderation, could have a negative influence on our youth. I have noticed the significant change that has occurred in technology in just a generation’s time. As a child, I remember when people were purchasing their first personal computers, usually for everyone in the household to share. These computers were not nearly as fast and advanced as computers are today. Now, nearly every home in America has a personal computer, laptop or some other way of accessing the internet, like a smartphone or tablet. While access to the internet can help educate children if used in an educational way, misuse of technology, like playing violent video games, could cause a......

...How technology has changed the world? Technology is the present world. It affects people’s daily lives. Whether it inspires somebody to be the master at videogames or makes somebody a computer hacker. It has changed the generation of teenagers/young adults rapidly. It has made the generation more greedy, ignorant, and lazy. For instance, my parents did not have fancy cell phones or high-tech computers back then because it was never created. They only had a bike and ball until it was worn out. They never thru a fit for not getting what they wanted or sat at home, playing videogames for numerous hours. They would always be outside, whether the weather was hot or cold, playing soccer or having a snowball fight with their friends. And when they didn’t want to go outside, they sat down, read a book, played cards, or even drank hot cocoa. Now a day, it’s all about getting an iPod touch or a phone with a touch screen. Soon, people will have chairs that will fly around to get a soda from the fridge so they don’t have to get their butt up and walk. Though there seems to be more negative influence of technology, there may still be some silver lining. Technology is taking over our world. People don’t realize what it is doing. In the music industry for instance, when a new song comes out by a famous rock star wearing a metal jacket with no shirt on and multiple piercings, people end up coming to school dressed the same way.

...Reflexes and More Vacuous Our nation changes and improves every year, and one of the many improvements that continues to evolve is computer technology. It becomes more prominent and is changing the generations of teenagers and adults as it continues to become more popular. Many can argue that computer technology is good or bad for our minds. Nicholas Carr has shared his view that technology is making our minds vapid. He states at the end of his article “Is Google Making Us Stupid?”, “as we come to rely on computers to mediate our understanding of the world, it is our own intelligence that flattens into artificial intelligence” (345). However along with all the advancements that can help our nation there are also a few technologies such as social media and gaming that does not exactly help improve our generation. Technology may be improving to be fulfilling the wants of people, however our nation needs a generation that does not spend their entire life on the internet. Therefore, social media or gaming is a drawback to computer technology because it begins to prevent people from using their full ability of brain power which will soon prevent from furthering technology in our world to better the nation. The internet and social media have benefited people by improving the knowledge that people have. Many great advances can come out of technology, because just thirty years ago our nation did not even know about the internet. However nowadays, it is used on a daily basis to......

...Nowadays, technology is transforming the way we live, work, learn and play. Although the growing number of people complain that resource shortage and environmental pollution become serious due to the development of technology, it is undeniable that technology has made the world a better place to live. In my opinion, technology has made people's lives more comfortable. Firstly, the communication between people is becoming faster and easier. Using the internet,we can make friends from different countries and share our feelings with them online. Also, we can send E-mails to our friends in a few minutes Instead of writing letters or sending postcards, the Internet enables us to send E-mails to our friends in a few minutes and know the latest information worldwide immediately. Secondly, technology has made our lives more and more convenient. For example, at the beginning, people used to travel on foot which would take them a great amount of time and energy. But now we have cars, airplanes and high-speed trains which make our journey faster and more comfortable. With the help of modern transportation vehicles , people can go everywhere they prefer to. Finally, advanced medical treatment and technology lengthen people’s life.For example, at the stone age, our ancestors’ average age was about 25. However, after people discovered the mysteries of gene, many deceases which were considered detal before can now be treated and cured. Now people’s average age is two or three......
