Introduction: Voice over IP or VoIP is a relatively new modern way of digital voice communication that relies on many communication protocols, technologies, methodologies, and transmission techniques. The distinctive feature of VoIP is that communication happens over the internet. VoIP is a revolutionary technology that has the potential to compete with the world’s telephone systems. Some engineers have indicated that the creation of VoIP is basically a clever “reinvention of the wheel” that relates to telephone communication.

Contrary to the misconception that VoIP induces, it does not deal only with voice transmission. VoIP technology can be considered a medium of transmission also for fax, SMS, voice messaging applications that are transmitted via the Internet rather than the PSTN or public switched telephone network. Some may refer to VoIP as IP telephone but these two terms are actually different since IP telephone has to do with digital telephony systems that use IP protocols for voice communication, while VoIP is actually a subset of IP telephone that transports phone calls and other type of digital information.

VoIP has a relatively short history since it began spreading in 1994 as a way of communication developed by some Israeli people. Later in 1995, the first VoIP company launched on the market, "Vocaltec". By releasing an internet phone software that could be added to a computer and its peripherals while using the internet, Vocaltec's software made it possible to allow users making phone calls over the internet. Quality was less than the normal phone of course and it required a symmetric setup at both end users (same design).

1998 was the year where VoIP became recognized worldwide as the potential technology making it possible to create high quality voice calls in 2 ways: computer to phone and computer to computer. Businesses began to

...How to Write a Critique The critique is a rigorous critical reading of a passage. As such, it picks up where the objective summary leaves off. In fact, a critique often includes a brief summary so that its readers will be able to quickly grasp the main ideas and proofs of the passage under examination. Critiques come in all shapes and sizes, but a good way to get used to writing critically is to plan your earliest critiques along the following lines. First, read the passage thoroughly. Make plenty of notes, ask lots of questions, and highlight or underline anything you may wish to quote in your paper. Spend some time on this step. It is impossibly to adequately critique something if you don't fully understand it. Next, write a summary. Identify the author's main point (thesis) and list the types of proofs he or she employs to persuade the reader to believe or accept the thesis. For example, does the author use historical anecdotes, quote noted authorities, provide statistical evidence, or appeal to a reader's sense of patriotism or generosity? These are all common types of proofs used in persuasive writing. You should also try to figure out why the author is writing, and to whom. Remember that the purpose of a paper and its intended audience can affect the way the paper is written. Now, set your own agreement or disagreement with the author aside for a moment and investigate the validity of his or her argument. Does the author provide complete and accurate information...

Gatsby Initial Impressions

...Initial impressions of Gatsby - Chapters 1-4 We see and hear relatively little of Gatsby in the opening chapter of the novel; he is presented as an almost ephemeral, ghost like figure. However we are drawn to his character by the way he is described: ‘There was something gorgeous about him, some heightened sensitivity to the promises of life’. Consequently, Every time he is mentioned there is always something to interrupt which adds to the mysteriousness of his character. At the end of chapter 1 we catch a glimpse of him where he is bonded with strong romantic imagery, he comes out to see ‘the silver pepper of the stars’ and is spotted when ‘the silhouette of a moving cat wavered across the moonlight’. Fitzgerald combines the purity and romance of Gatsby’s dream with these symbols. On the contrary when he gives a ‘sudden imitation that he was content to be alone’ by stretching out his arms towards the ‘dark water in a curious way’ the purity of his character seems to disappear as the ‘single green light, minute and far away’ suggests the ill omen of his character. In Chapter 3 Fitzgerald uses the part scene to introduce Gatsby to the reader, here Gatsby emerges as a mysterious character who is the subject of gossip, He is well known but ironically nobody seems to have any verifiable information about him. Nick then describes him and says ‘he had one of those rare smiles with a quality of eternal reassurance in it’ the way Gatsby us portrayed is one of extreme modesty, he appears...

My Communication Class

...During the in class exercises I truly learned a lot about myself. I was completely amazed at how I never knew the things about myself. I remember on the first day of class we had this ice breaker/Activity we had done that really made me get in the spotlight. We had to introduce ourselves. As I walked in front of the class I realized that I was truly nervous. The closer and closer I got to the front of the class the more nervous I became. When I finally had reached the front I had turned to my peers and realized that all eyes were all on me. Being overwhelmed, I continued you on to the introduction of myself by saying “Hi, my name is Roman Guillory…” and the rest of my introduction. As I closed my remarks and had a seat I just set back and watched my peers as they tackled the same situation. Watching them speak made me feel better because I realized that they were feeling the same way that I had felt when I was up there. Another activity that I remember doing is the group activity. We all had to cut things out the magazine representing what looked ugly to us and what looked good. This activity really engaged us to communicate with each other effectively and ultimately decide which things we should do as a team. Even though we all had different personalities and viewed different things as looking bad or good, we all came to a considerable decision on what will be glued to the poster and what wasn’t. All in all, I truly liked most of the activities that we did in class and some them...

Case Study 2 Internal Control

...Case Study 2 -Internal Control Due by Sunday of week 5, 11:59PM, Mountain Time LJB Company, a local distributor, has asked your accounting firm to evaluate their system of internal controls because they are planning to go public in the future. The President wants to be aware of any new regulations required of his company if they go public so he met with a colleague of yours at a local restaurant.
