Application Level:
An example of a highly important protocol which will be utilized at application level, is HTTP or hypertext transfer protocol. HTTP is the protocol used within web browsers and the entire internet to send and receive specific web page data. HTTP is a controlling protocol, as it determines how documents should be sent, and what the browser should do in response to commands. When accessing a web page, a HTTP command is sent to the pages web server, so that the server may send that specific page’s data to the user. PCO’s Learning Centre will be using the hypertext transfer protocol on a regular basis. In order for students to access web pages, the HTTP must exist to ensure speedy and accurate navigation, especially in a learning

Ethernet is often built into hardware devices such as network interface controllers, to allow the sending and receiving of data packets to that piece of hardware. Ethernet can be used to create a wired local area network, which can subsequently communicate with other LAN’s, ad infinium, which in turn creates the internet. Ethernet uses a system called CSMA/CD or Carrier Sense Multiple Access with Collision Detection. This system is able to deal with collisions which happen when two messages are sent at the same time. When two nodes on a network attempt to exchange data at the same time, they collide and create an error. When this happens, all nodes involved are notified. The Ethernet protocol will then set a random time interval, after which the node will re-attempt the transmission. This will be done until the message is successfully sent. Just as the hypertext transfer protocol and transmission control protocols will be used every single time a student at PCO’s learning centre accesses internet, so too is the ethernet protocol. This, however, will be done in a slightly different way. As the students will be using Wi-Fi to connect to the modem, ethernet will not be used. In saying this, ethernet will be used to connect to the NAS and the printer. For example, if two students want to print something, and they do so at the exact same time, the messages will collide. As the printer is connected through ethernet, the printer, and two computers will be notified of the collision. The ethernet protocol will then set a random time interval, and the printing request will be sent again at different times for each computer. Although this is a reasonably complex process, in real time, the students will have no idea this is happening, and the printer will print both students documents like nothing has
The moral philosophy best describes my personal decision making is virtue ethics (Ferrell, Fraedrich, & Ferrell, 2013). It best description of me as virtual ethics having exceptional moral character (Ferrell, Fraedrich, & Ferrell, 2013). My character displays honesty, integrity, and helpfulness (Ferrell, Fraedrich, & Ferrell, 2013). For example, a friend attempted to commit suicide as a result of a wife asking for a divorce through email (Ferrell, Fraedrich, & Ferrell, 2013). However, while working I received a phone call from him stating his desire not to live anymore (Ferrell, Fraedrich, & Ferrell, 2013). Meanwhile, I called his son to ensure that he wasn’t alone however, his son drove to the house and found his father sitting and with a
On Monday, 02/01/2016, at approximately 18:48 hours, I, Deputy Stacy Stark #1815 was dispatched to handle a telephone report for Identity Theft. I returned a telephone call to the victim, Lisa A. Gross (F/W, DOB: 08/12/1962). Gross lives at 1617 Camp Creek Murphysboro, IL 62966.
Application Virtualization: Application virtualization conveys an application that is facilitated on a solitary machine to a substantial number of clients. The application can be arranged in the cloud on high-review virtual machines be that as it may, in light of the fact that a substantial number of clients get to it, its expenses are some common by those clients.
From 2011 and onward, my family had fallen into bankruptcy for paying out of pocket for my older brother’s medical expenses and surgery costs due to his diagnosis of heart failure. In 2013, when I took the standardized ACT exam two times, I scored both times an 18 which was below my university’s 2014 entering freshmen class’s composite score average of 24.5 (copy of score report is attached). Furthermore, upon taking the LSAT two times with over four months of self-studying for the September exam, I scored first a 141, and a 140 on my last attempt. When taking both examinations, I have not been able to afford tutoring pertaining to the exams or a preparation course. Although I have worked numerous jobs during the past few years in college,
In the beginning of the course, we discussed “NGD”. The two areas of “NGD” that we focused on were number and geometry. Number is discrete, finite, time, or sound. Geometry is continuous, infinite, space, or vision. Bronowski mentioned how “it’s said that science will dehumanize people and turn them into numbers” (374). This tragically became true during the Holocaust where people were no longer considered human beings, but rather numbers. We discussed various mathematical topics concerning numbers like the well-ordering pair. In the well-ordering pair, ever subset has a least member. There are also figurative numbers, squared numbers, and even Pythagorean triples.
1.“If, for example, students were not ultimately rewarded for spending their early adulthoods pursuing undergraduate, graduate, and professional degrees, or if the hardest-working and most productive workers were paid the same as the median worker, then citizens would have little incentive to develop expertise, to exert effort, or to excel in their work.”
It's important to gather information that is understandable by your students. The procces of gathering evendce in childrens learning can make a huge difference. there are many different kinds of assesments that help you as a teacher better educate your students. your lessons plans and what you teacer is very important to what they understand and how they learn.
In the early 60’s, a group of visionaries anticipated the very idea of the Internet that shortly after the cold war, the U.S Department of Defence (DOD) began to realize the incredible potential value that shall come from a control center system that protects the flow of information between in case of nuclear attacks, by establishing a network of computers geographically distributed and sharing data. So, they funded the Advanced Research Project Agency (APRA) to start a project (Bellis, 2011). APRA proceeded with the idea as a military experiment. Meanwhile, at the CERN (Centre Europeen de Recherche Nucleaire) in Switzerland, a proposal was made with an academic approach for a technology that will enable collaboration in the physics community to connect research institutes and universities together, allowing scientists to share files and academic study resources (Gribble, 2011). The Internet development had many groundbreaking milestones to cover, mutating it from a simple package of protocols into a complete working platform of worldwide information. The spotlight is thrown on the beginnings of ARPANET, HTML (Hypertext Mark-up Language) technology and the WWW (World Wide Web) birth at CERN, till reaching the Internet development in the late 20th Century.
One of the most widely used technologies is the Internet, or also known as the World Wide Web. “In August 1981 about 200 computers hosted Web servers. By July 1998 there were over 36 million Web servers, that are hosts to approximately 150 million people” (Strauss). The Internet proves to be very beneficial to education, since students have unlimited access to millions of websites with tons of information. There are only so many newspapers, journals and magazines that you can find in libraries or subscribe to. Therefore, the Internet offers an unlimited pile of information that students can always have. Moreover, students are enriched with the most current information in any subject, along with regular updates. Students are able to use the Internet anytime of day, as long as they have a computer at hand. The research process will not have to end when the school day is over (Wissick, 82).
The human body is everything that makes up, well, you. The basic parts of the human body are the head, neck, torso, arms, and legs. Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The following paragraphs are going to explain the functions of two different body systems.
The student’s information is at risk each time a file from a message, hyperlink or image is accessed. To address such a challenge the instructor needs to make sure that all communication is on a secured hypertext transport protocol site. This authentication is provided by the institution that the educator is affiliated with and it ensures that communication between the student and the instructor is on a secured network regardless of the browsers and servers used.
The Internet offers a huge wealth of information, both good and bad. The Internet began as a small university network in the United States and since then has blossomed into one of the biggest if not the biggest telecommunications network covering the entire world. It can be considered as one of the most valuable types of technology. During the past several years we have come to become more and more dependent on the Internet and in particular moving huge chunks of data across large distances. The Internet allows people to communicate with each other across the world within mere fractions of seconds with the help of E-mail. The Internet also allows for expressing opinions and obtaining up-to-date information from the World-Wide-Web. New software is being developed everyday which uses Internet as the carrier for long distance voice calls and video conferencing which would hold the key to the future of our society.
Since the development of the Internet in late 1980s, communication has changed enormously. The Internet has altered the lives of people in the world in a way that was never imagined before. As little as a decade ago, if someone tried to explain the Internet and World Wide Web, it would have been difficult, if not impossible, to understand. Computers were just beginning to become popular and few individuals realized the capacity of one PC, let alone the power of a network of electronic technology. By linking together computers, users could remotely access others on the network, share information, and send electronic mail as easily as pushing a button. Millions of people with shared interests, exchange information and build communities through Web sites, email and instant-messaging software.
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate.
