Why do you think the world is running out of IPv4 addresses? The internet really started in the 70s as a DARPA research project. At the time, there were 60 or so institutions expected to connect. As the interested research community grew, the addressing scheme was expanded from 8 bits (256 addresses in the predecessor to Internet Protocol (IP) known as Network Control Protocol (NCP)) to 32 bits (the IPv4 addresses we have today). At the time, it was still expected that the internet would serve largely defense, research, and educational institutions.
He noticed the Net was having a much stronger influence over him than his PC ever had (324). Carr does not say if it is positive or negative that the Net was having such a strong influence on him. Like it or not, the Web has made such an impact on society that Carr concludes, “What’s clear though, is that for society as a whole the Net has become, in just twenty years since the software programmer Tim Berners- Lee wrote the code for the World Wide Web, the communication and information medium of choice… by choice or necessity, we’ve embraced the Net’s uniquely rapid-fire mode of collecting and dispensing information” (318). It does not matter if one uses the Web as a want or need, the Web has become the communication and information medium of choice. Carr discusses the disadvantages and advantages, but feels ambivalent and does not feel strongly for or against the Web.
The current version of the Internet Protocol IPv4 was first developed in the 1970s, and the main protocol standard RFC 791 that governs IPv4 functionality was published in 1981. With the unprecedented expansion of Internet usage in recent years, especially by population dense countries like India and China, the impending shortage of address space (availability) was recognized by 1992 as a serious limiting factor to the continued usage of the Internet run on IPv4 (Das, 2013). The Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP). It is a communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion.
Computer business systems have been around for 40 years. Desktop computers have been around for 20 years. Why do business systems, in general, still need more development? o Please respond to Question 1 no later than Saturday, Day 5. There are many reasons why there needs to be constant development of new systems.
For example, the University of Michigan had fewer than 10,000 students prior to the war, but in 1948 its enrollment was well over 30,000. Syracuse University also embraced the spirit of the Bill and saw its enrollment skyrocket from approximately 6,000 before the war to 19,000 in 1947. Another provision was known as the 52–20 clause. This enabled all former servicemen
”Several terabyte+ drives have recently broken the $0.10/gigabyte barrier, making the next milestone $0.01/gigabyte, or $10/terabyte.” (Komorowski, 2009) With Moore’s law in effect, I believe we will see a 100 TB hard drive within the next twenty years. Engineers at Florida International University have already uncovered a way to break the 2D limitation of magnetic hard drives, by going 3D and drastically increasing the areal density. As of now, they are potentially capping 60 TB
The Pentium chip which is the most common 1993 chip from Intel contained 3,100,000 transistors. The technology behind transistors over the years has changed, they are made smaller so that microprocessors could be fitted with more, which gives faster processors. The co-founder of Intel, Gordon E. Moore in 1965 described how the amount of transistors for integrated circuits which had doubled every year, Moore predicted that for at least the next ten years the trend would continue. Now more than forty five years later this prediction is still somewhat correct. Moore stated that this could continue another decade or two, but would eventually reach its limits at atomic levels of miniaturization.
Explorer 1 had an orbital life cycle of about twelve years, and mission duration of four months. Upon re-entry to earth in 1970, it had completed an astounding 58,000 orbits around the Earth. At the same time as the Vanguard rockets (the satellites proceeding Explorer 1), President Eisenhower and the rest of his cabinet were trying to decide under which agency this new “space” issue fell under the jurisdiction of, to which they found no answer. President Eisenhower instated the National Aeronautics and Space Act which was the creation of the National Aeronautics and Space Administration or more commonly known as NASA. NASA would go on to become the most influential organisation in the world in relation to anything space related.
One of the first points that Hornsby tries to make is that Carr’s argument has not been proven by any long term studies. Carr is just basing his essay’s argument off of his own experience and personal opinions. In 2008, however, a study was done at UCLA that gave sufficient evidence that searching the web actually aids and improves a person’s brain function. The article states that”UCLA scientists have found that for computer-savvy middle-aged and older adults, searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function.” (Internet Altering our Brains .1) If this study is accurate then it
The influence of technology on the application process is more subtle; nobody is getting into a school because of a good tweet. The University of Chicago uses its alumni and student email networks, for example, to crowdsource its famously clever essay prompts. And the vast majority of applicants even to new-media-friendly schools still opt for the traditional written essay. And that’s fine, says Tufts’ Coffin. The point isn’t to force potential students to play by a new set of rules, let alone provide them techno-shortcuts.
