Computers - Essay Example This essay is an evaluation of computer networks dedicated to laptop desktop connection. Data communication is the transfer of information from the sender to the receiver through a communication medium. The most common media for this process include cables, air/waves and satellite etc. Telephone communication starts with the sender initiating a connection by dialing the recipient’s number from his data transmission equipment (DTE) (Harte and Ofrane 2006). Once he does this, the call passes through either a public switched network (PSTN) or a private branch exchange (PBX) depending on the nature of the call. A PBX is a telephone switching exchange that is dedicated to controlling telephone communication within a company or an organization. It connects calls within the company by providing extensions to calls that originate from various offices instead of hiring lines for every department. It also connects calls to outside networks. A PSTN connects local and international calls, in a large network structure that is not restricted to a specific subscriber or organization (Harte and Ofrane 2006). Once the call is switched to his address, the receiver is alerted and to complete the connection, he has to switch on his DTE to start transmission. Telephone switching companies also offer internet connection services through their satellites which act as gateways to wide area networks. This connection involves transmission of digital signals through analog transmitting lines. For this to occur, modems are connected on both ends of the transmission for the purpose of modulating (converting digital signals into analog) the signals from the sending machine and demodulating (converting analog signals back into digital form) signals on the receiving machine (Hennesy 2006). This is because computers only understand digitized information which is in binary form i.e. 1s& 0s A

Analysis of Silkos Style - Essay Example The writer has introduced his work by a rhetoric question to the reader â€Å"What about Silko’s Style?† putting across the argument topic. And in the conclusion gave the final appeal and suggested the reader to decide which argument is better. The piece invokes the reader’s curiosity as a question is asked and then points are laid down so that the reader is persuaded to accept the writer’s argument (Faigley and Selzer). The writers chose a direct and simple language to make it easier for the reader to understand his point. As a reader, the piece is easy to grasp the point and makes it interesting to read. The point from the first paragraph â€Å"simple, straightforward, unadorned – because she wants her readers to accept her narrative as credible and trustworthy†, was the most significant as it shows that rhetorical choices made by writers are for achieving certain effects on readers (Faigley and Selzer). The writers repeated the word rhetoric many times in the second paragraph however it does not seem redundant because they have used it carefully and in a different manner each time. Another point that is about Silko’s writing style is discussed a few times in the piece however it is for stressing the point of rhetoric choices writers make and the words used every time are different. The central point of the piece is â€Å"Textual rhetorical analysis employs rhetorical terminology† (Faigley and Selzer). As the writer used a rhetoric question, similarly in news paper’s articles, motivational and public speakers and in many literary works rhetoric question and rhetoric analysis is used to persuade the audience. This reminds of a very good orator US President Obama’s acceptance speech in 2008, in which he posted a famous rhetoric question â€Å"What is that American promise†, and is claimed that his rhetoric strategies persuade, bring home the point and convey his vision to his audience in a very clear manner and their hearts and minds get swayed (Leanne, 1).
