...gain the necessary qualifications that will help me in my future business endeavour. I have found that after so long out of the education system it has been a difficult transition juggling study and work. The first units that were chosen for me in study period 2, I thought were difficult to understand having never written an essay before and without the knowledge or know how, I was not able to complete these units. SSK12 has given me a good understanding of what it takes at becoming a university student and in particular the skills on writing essays. As I have mentioned previously up until study period 2, I had never written an essay and did not fully comprehend how important the set out of a university essay was.

...Cell Phones – The first generation of cell phones transmitted voice through an analog wireless connection.

A cell phone is used for full duplex two-way radio telecommunications (for both voice and data) over a cellular of stations known as cell sites. Landline Phones – Landline phones use analog voice. They are connected to the Central office by a local loop that is 2 copper wires in a twisted pair. Landline phones get their power from this local loop. Also call POTS nowadays or Plain Old Telephone Service. SMS/Text Messaging – SMS stands for Short Message Service. The control channel (a pathway from your cell phone to the cell tower) provides the pathway for SMS messages. When you send an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to the phone as a little packet of data on the control channel. Fax Machines – Fax Machines connect to another device on the other end of the line. They convert the images to data and transmit them over the analog telephone lines. If the spot of paper that the photo cell was looking at were white, the fax machine would send one tone; if it were black, it would send a different tone.

...First & Last Name First & Last Name English 101/Section # Date Essay #2 The Committer vs. the Non-Committer        There are many types of men in the world, and each type displays a variety of distinguishable characteristics. Women should become aware of these characteristics before considering a prospective mate. The smallest of personal details, from where and how they met (including the first date), the way he walks and talks, the clothes he wears, the career choice he's made, the vacation spots he frequents, or the automobile he drives can offer valuable, meaningful, insightful clues to whether or not a man will ever settle down with anyone. There are two main types of men in the world: the committer and the non-committer. The committer is serious about finding the right woman. He asks friends and relatives for introductions. He is usually open to blind dates and avoids the bar scene when looking for a quality woman. On the first date, he is polite and will not bring up the subject of money at the restaurant. He takes her to places where they can talk one-on-one. The non-committer is just looking for a woman. There is no room in his life for the woman. He, on the other hand, loves the bar scene. He usually finds a million excuses why he can't find the right woman and uses such excuses to explain why he is still unattached. On a date, he orders trendy food such as sushi to impress his date, and he monopolizes the conversation. He may even take her to places where...

Villages in Bali have many different kinds of temples, but they all have a pemangku (priest): the more important ones also have a klian (secretary) and a beddesa (calendrical expert). The klian and bedesa are elected; the pemangku may be designated by patrilineal succession, elected by the congregation or chosen by God through a possessed temple medium (Barth, 1993). There...

Summary of on the Meaning of Plumbing and Poverty

...Bryce Gray English 1103 Summary & Strong Response On The Meaning Of Plumbing and Poverty Summary In her essay “On The Meaning Of Plumbing and Poverty,” Journalist Melanie Scheller examines the cultural identity of the rural poor. The author brings the readers attention to her call to action about poverty in America while using facts and personal background. While caring for a woman in a psychiatric ward, Scheller witnesses the woman’s obsession for flushing the toilets in her unit. This memory creates an opportunity for her to write an essay about growing up in rural North Carolina. In the 1960’s the author was growing up with her mother and five other siblings, moving from place to place in search of a home where the rent was affordable. Scheller mentions how she lived in a house with five rooms, with one room in particular for her and her siblings to gather in to complete homework or watch television. Furthermore, Scheller describes how “in the South” of her childhood, if a family did not have indoor plumbing they were labeled as white trash and strongly stereotyped at school. They often had comments thrown at them such as “White-trash children had cooties- everybody knew that”(321). When Scheller is granted a college scholarship, she describes the feelings of happiness and delight she encounters when given the opportunity to use as many clean toilets and take as many hot showers as she wishes. Having this newfound privilege is a blessing but she is ashamed...
