Byte

will work against each other, Nagle's algorithm won't send it's last packet unless it gets an ACK, but the delayed ACK won't be sent because the server still doesn't have all the data it needs. This can cause a slowdown if the buffer sze is 100,000 bytes (Cheshire, 2005). 5.Why does UDP exist? Would it not have been enough to just let user processess send raw IP packets? We could use IP to send information between hosts, but we would have no way of knowing which application it needs to go…

In the twenty-first century, many of us think of money as paper or even as bytes of data to be exchanged electronically. But coins were the commonest medium for money in the past and continue to be in much of the world today. Even the United States has re-introduced a dollar coin. At the start of the Republic, Romans were still using the barter system, and cattle -- pecus -- were the standard of exchange. In fact, it was from pecus that the Latin word for money, pecunia, was derived. Eventually…

Josiah Avery walked through his home office door and sighed. It had been an extremely long day. He eased his tall, athletic frame into leather, winged backed chair and let the cares and concerns of the day tumble freely to the floor. As he opened his worn attaché case and placed his hand inside, Josiah smiled. He could fill the smooth, beveled edge of a new Microsoft Surface Pro 4 tablet pc. What a beautiful piece of hardware! Windows 10, 8 GB (gigabytes) RAM for incredible fast…

the vice president for research and development at Apple. The Apple I was similar to the Altair 8800 except it did not use internal expansion cards. Wozniak’s design of the Apple I included a twenty-five dollar processor on a 256 byte ROM circuit board, 4K or 8K bytes of RAM and a 40 by 24 display controller. A user of the Apple I had to provide a power supply, keyboard, and display on their own because the computer did not have those…

‘survival machines’, and disagrees with the concept of humans having any kind of soul to distinguish them from other species. In addition to this, in his book ‘River Out of Eden’ (1995), he states ‘there is no spirit-driven life force … life is just bytes and bytes of digital information’. His reductive materialistic ideas are scientifically sound; however, Keith Ward argues that without the soul, humanity lacks any sense of final purpose. If we do not have a soul, and we are nothing more than…

Tiananmen Square Protest 1989 People protest for a reason, there is a problem with something and they want a change, they want to be heard. They can last for a long time, days, months and years until they get what they want. During protest things can get out of hand and people become violent and that’s where everything gets too far. Today protesting isn’t as bad as it was before, we try to result to agreements and there aren’t as many deaths as there were as before. In 1989 Tiananmen Square was…

Gwendolyn Brooks was one of the few poets able to move between the academic poets of the 1940’s and militant writers in the 1960’s, creating a fresh style of poetry that reflected the philosophic struggle each African American woman dealt with during this time. Her words spoke of the pain which comes with trying to better one’s life, especially in the face of extreme poverty and racial inequality. Upon initial reading one may see a theme of the stereotypical African American female, often…
