Processors
As we have discussed in class, the textbook is constrained by the time it takes to write and publish the information/topics. We have access to the Internet, so here is your assignment for this week.
Processors currently are silicone chips, but these devises are rapidly becoming inefficient as processing needs increase. Research some of the new processor technologies, including nanotubes and graphene. Remember to summarize your findings, then post a relevant URL along with your name.

OP SYS Memory
In the past it was not if your operating system would crash, but when it would crash. So, you back up everything. The system only did one task at a time and slowly. Today we have fourteen systems and counting.
As the computer got faster and more device was added. The operating systems also got faster and larger to hand the new demand. We have manages to break down the work load put on the computers.
Present computer structural designs assemble the computer’s memory in a hierarchical process, beginning from the highest registers, random access memory manger, CPU cache, and disk storage. A computer operating systems memory manager synchronizes the utility of these numerous kinds of memory by tracking which one is obtainable, which is to be assigned or de-assigned and how of progress data between them.

Nanotechnology can actually revolutionize a lot of electronic products, procedures, and applications. The areas that benefit from the continued development of nanotechnology when it comes to electronic products include nano transistors, nano diodes, OLED, plasma displays, quantum computers, and many more.

Silicone chips are starting to get limited. The cell processor was a great start starting off 2005 with the Playstation 3 and IBM super computer.Cell combines a general-purpose Power Architecture core of modest performance with streamlined coprocessing elements which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation.But I also see this being implemented into the cell process.

With increasing demand of everything wanting to be micronized or everything shrunk to the smallest size possible the properties of silicon is reaching its limits. Reaching the size limit of these conductors the problems of electrical leaking through layers, causing overheating, and leading to faulty logic. With carbon nanotube technology, this can greatly be reduced, nanotubes have better conductive properties then silicon, and smaller than the current hardware used today. The possibilities of nanotube technology is going to be endless, developers are just beginning to discover use and design applications for nanotubes. Is this the way of the future? I believe so.. With all the applications that can benefit from nanotubes …

As the use for silicon clearly deminishes, new processor technology such as carbon nanotubes and graphene have appealed quiet efficient from what I've asorbed from my reasech. They both have extremely intriguing properties. Carbon nanotubes have much faster circuits due to a
much higher charge in mobility values compared to organic semiconductors. Reading on in my reseach I've found it is expensive, being that it's a relatively new technology . This currently limits the
potential of these nano-carbon products.
Graphene is building block among all other allotropes such as normal graphite.
It was noted that, as the basic building block of carbon nanostructures, graphene
structures have been widely studied in the academic world.

Processors from the past has got faster based on what was put in the computer. Graphene will be the the source to the future . Soon its going to be what computer uses.
I think soon graphene will be absolete too.

One of the newest changes in processors is the material the chips are made from. The majority of computer chips were made with silicone. Just recently, chips made from carbon were not possible due to the fact that the graphene needed to be in the same form as the silicone. the new method of stamping consisted of tiny pillars that are pressed against graphene. The new method became immediately useful in cell phones, radios, and other wireless devices that require power outlet.

The use for graphene in computer processors was originally discovered by Walter de Heer, a Georgia Tech physics professor.Today's silicon-based computer processors can perform only a certain number of operations per second without overheating. But electrons move through graphene with almost no resistance, generating little heat.Graphene itself is a good thermal conductor allowing heat to dissipate more quickly. This factor makes graphene a good choice for computer processors because it can work at much higher speeds without overheating.

Nanotubes are the future of our processor's within CPU's. This Technology currently under development allows for more powerful processors, which leads to more powerful computers. IBM back in 2002 found a way to make nanotubes with silicon as the catalyst instead of metal in there nanotube fabrication process. This shift can show the most promise for circuitry in the future. With carbon nanotubes in the running to replace wires in chips and other components, silicon nanotubes could improve manufacturing yeilds of single-wall nanotubes. So with the development of these nanotubes on the horizon its just a matter of time before these small tube like structures become our future beacuse they conduct electricity well, and allow manufacture's to squeeze billons of transitors into a single chip, allowing processing demands of the futher to be met, and overheating non exsistent.

Computers will always evolve to the next level. Where silicone chips are used now and the devolepment of nanotubes and graphene are what seems to be the wave of the future soon they too will be old news. Soon enough there will be no where else to go.

reading up on graphene I found that graphene will pretty much revolutionize technology as we know it. With graphene able to reach 1000GHz of speed, jobs and work loads on the computer will be much faster.

While the sexier Graphene seems to keep coming up as the future of computing the carbon nanotube transistor technology being developed today would seem to be the heavy lifter for tomorrow’s computers. New computer chips built with carbon nanotubes will have far superior speed and energy efficiency and soon the ability to build 3-Demensional circuits.

The future of processing lies in quantum mechanics. While little progress has actually been made thus far, recent advances have shown considerable progress, and it is thought that our quantum computing capabilities will double within the next year. D-Wave Systems claims to have produced a 50-qubit system, but much of scientific community is skeptical as to whether the system exhibits true entanglement or not.

Nanotechnology is already contributing to increased data storage capacity and processing speeds. Molecules will be able to make steel beams 100 times stronger and even 6 times lighter. It will make the computers faster even though the actual size of the chips and transistors are much smaller than they are now. Nanotechnology is predicted to be developed by 2020.
Graphene is it the thinnest possible material feasible, it’s also two hundred times stronger than steel and conducts electricity better than any material known to man-at room temperature. Graphene future holds limitless possibilities into every corner of industry and manufacturing.

As a paper battery
A paper battery is a battery engineered to use a paper-thin sheet of cellulose (which is the major constituent of regular paper, among other things) infused with aligned carbon nanotubes.[113] The nanotubes act as electrodes; allowing the storage devices to conduct electricity. The battery, which functions as both a lithium-ion battery and a supercapacitor, can provide a long, steady power output comparable to a conventional battery, as well as a supercapacitor’s quick burst of high energy—and while a conventional battery contains a number of separate components, the paper battery integrates all of the battery components in a single structure, making it more energy efficient.

I found an interesting video about graphene on you tube. It discusses the Nobel Prize winners for discovering graphene. In fact, they accidentally discovered some of the technologies. I recommend that everyone watch this video. It is very interested and goes in to great detail about graphene and its possibilities.

Nanotubes are mad of extremely strong materials that have good thermal conductivity. They are shaped like tiny springs that are thousand times smaller than a human hair. Coiled nanotubes are better than a sheet of straight nanotubes. They recover better.

IBM recently has demonstrated their new graphene transistor. It can execute 155 billion cycles per second. Using standard semiconductor manufacturing processes these transistors can be produced at a low cost. The transistor has benefited from the use of a new and improved substrate called "diamond-like carbon."
