    Butler’s Information Resources department played a major role in establishing the new VoIP system at Butler University. The IS department began this entire project by first researching the current system at Butler and identifying what they currently had, and what they needed. They looked at the features provided by Centrex and how their current system worked and developed a plan of what they needed to improve and add to their system. Butler’s IS department researched other systems, listened to vendor presentations, and set up interviews with numerous potential providers in order to narrow down their decision of what system they would be installing. The IS department came across a system called VoIP that was extremely intriguing to them. Although it was a fairly new and expensive system, they saw it as an opportunity to improve their current system drastically. “Only twelve to thirteen percent of the market had VoIP installed in 2004. Even though the telecommunications landscape was changing with an emerging trend of increasing IP lines, the current statistics were still daunting and left us wondering if this was a good path to…

    Anwar F. Accawi starts the essay “The Telephone” by telling about the way people in his village looked at the time was to notify that time was not important for the people who lived in his village at his period. Accawi in his first paragraph writes that “time didn’t mean much to anybody, except may be to those who were dying , or those waiting appear in court…” from these lines Accawi tries to states that time was not important for every people in his village except for some who were dying and some who were waiting appear in court. Furthermore he tries to explain the shoddiness of the villagers by starting that the villagers didn’t even wanted to know the time. Accawi takes this point as a negative impact of villagers; he expresses the uneducatedness of the villagers by printing “now could you? Satisfied with her answer,” he compares the current situation with his time period.…

    The Telephone

    “Before the telephone came to Magdaluna, Im Kaleem’s house was bustling at just about any time of day, especially at night, when its windows were brightly lit with three large oil lamps, and the loud voices of the men talking, laughing, and arguing could be heard in the street below—a reassuring, homey sound” Anwar F. Accawi (p. 46). It’s hard to imagine that a single device such as the telephone, albeit a breakthrough in technology, could change not only a person’s day to day life, but an entire village. These men in the village experienced all of the luxuries the village had to offer at no cost, Im Kaleem provided the men with a place to gather for conversation, games, drinks and sexual services. The children used to hang around Ima Kaleem’s courtyard playing games waiting for a call down from some of the men requesting errands in exchange for money. But that all changed once the telephone was installed, most of the men would now sit at Abu Raja’s store, “they were always looking up from their games and drinks and talk to glance at the phone in the corner, as if expecting it to ring any minute and bring news that would change their lives and deliver them from their aimless existence”. (p.46) Exposure to the telephone not only affected the men in the village, but it also affected the women, children and their entire way of life.…
