Week 2 Checkpoint
The business world is constantly evolving and part of that evolution is the way it uses wide area networks. Business’s often employ several different types of data in order to stay current but also to maximize their profits. On a typical wide area network, three types of medium that often are used are voice, traditional data, and video. Because of the reliance on telephone calls, businesses have many options. A private branch exchange is used by many larger businesses that need more than one employee to have access to a phone call. This is simply a phone switch that is either bought or leased in which a company can control. This gives their employees an easy way to access a certain call from many levels of a facility, but also gives them the option of calling within the network. Voice over internet protocol is using the internet to send telephone calls. A traditional private branch exchange makes use of existing telephone systems while voice over internet protocol instead relies on internet service provider’s network. A private branch exchange can also have voice over internet protocol functionality. Traditional data and video are also things a company may need to use in order to conduct business. Video data is as it implies data that gets processed in the form of a video. Video files can be traditional data files for sending, but streaming services can also be used. A video stream is essentially a video played on demand without a permanent download and can be viewed as it loads. Traditional data covers all other aspects of data such as text files and encryption keys.

Israeli Palestinian Conflict

...5/8/2014 Israeli–Palestinian conflict - Wikipedia, the free encyclopedia Israeli–Palestinian conflict From Wikipedia, the free encyclopedia The Israeli–Palestinian conflict (Arabic: ‫اﻟﻨﺰاع اﻟﻔﻠﺴﻄﯿﻨﻲ‬ ‫​- اﻹﺳﺮاﺋﯿﻠﻲ‬ al-Niza'a al'Filastini al 'Israili; Hebrew: ‫​הסכסוך הישראלי-פלסטיני‬ Ha'Sikhsukh Ha'YisraeliFalestini) is the ongoing struggle between Israelis and Palestinians that began in the mid-20th century.[1] The conflict is wide-ranging, and the term is sometimes also used in reference to the earlier sectarian conflict in Mandatory Palestine, between the Zionist yishuv and the Arab population under British rule. The Israeli–Palestinian conflict has formed the core part of the wider Arab–Israeli conflict. It has widely been referred to as the world's "most intractable conflict".[3][4][5] Despite a long-term peace process and the general reconciliation of Israel with Egypt and Jordan, Israelis and Palestinians have failed to reach a final peace agreement. The remaining key issues are: mutual recognition, borders, security, water rights, control of Jerusalem, Israeli settlements,[6] Palestinian freedom of movement,[7] and resolving Palestinian claims of a right of return for their refugees. The violence of the conflict, in a region rich in sites of historic, cultural and religious interest worldwide, has been the object of numerous international conferences dealing with historic rights, security issues and human rights, and has been a factor hampering tourism in and...

U.S./Israel-Palestine Notes Preface to the First Edition (1986) St. Augustine tells the story of a pirate captured by Alexander the Great, who asked him "how he dares molest the sea." "How dare you molest the whole world?" the pirate replied: "Because I do it with a little ship only, I am called a thief; you, doing it with a great navy, are called an Emperor." The pirate's answer was "elegant and excellent," St. Augustine relates. It captures with some accuracy the current relations between the United States and various minor actors on the stage of international terrorism: Libya, factions of the PLO, and others. More generally, St. Augustine's tale illuminates the meaning of the concept of international terrorism in contemporary Western usage, and reaches to the heart of the frenzy over selected incidents of terrorism currently being orchestrated, with supreme cynicism, as a cover for Western violence. The term "terrorism" came into use at the end of the eighteenth century, primarily to refer to violent acts of governments designed to ensure popular submission. That concept plainly is of little benefit to the practitioners of state terrorism...

...John Fitzgerald "Jack" Kennedy (May 29, 1917 – November 22, 1963), commonly known by his initials JFK, was an American politician who served as the 35th President of the United States from January 1961 until he was assassinated in November 1963. After military service as commander of Motor Torpedo Boats PT-109 and PT-59 during World War II in the South Pacific, Kennedy represented Massachusetts's 11th congressional district in the U.S. House of Representatives from 1947 to 1953 as a Democrat. Thereafter, he served in the U.S. Senate from 1953 until 1960. Kennedy defeated vice president and Republican candidate Richard Nixon in the 1960 U.S. presidential election. At age 43, he was the youngest to have been elected to the office,[2][a] the second-youngest president (after Theodore Roosevelt), and the first person born in the 20th century to serve as president.[3] To date, Kennedy has been the only Roman Catholic president and the only president to have won a Pulitzer Prize.[4] Events during his presidency included the Bay of Pigs Invasion, the Cuban Missile Crisis, the Space Race—by initiating Project Apollo (which would culminate in the moon landing), the building of the Berlin Wall, the African-American Civil Rights Movement, and increased U.S. involvement in the Vietnam War. Kennedy was assassinated in Dallas, Texas on November 22, 1963. Lee Harvey Oswald was arrested that afternoon and charged with the crime that night. Jack Ruby shot and killed Oswald two days later...
