Software engineers Essay There have also been improvements in the protocols applied by the internet. In its inception the type and the capacity of data that could be passed through the internet was limited because the mechanism that enable its functioning, referred to as protocols, could not support complex data formats and large data sizes. Software engineers, web designers and application designers have worked so hard over the years that it is currently easy to pass data over the internet in almost all existing formats. The most common web browsers support the sending of multimedia over the internet, furthermore the live streaming of videos and clips is possible with the protocol applied with the latest versions of browsers (Jayne, 1999). It is even possible to chat with friend over the internet and the teleconferencing mechanism that the internet technology has been targeting for so long is now in place. Education is an aspect that requires creativity and integration of various modes of data delivery, the use of plain text, videos, audio streaming, visual aid and real life examples characterises the current American educational system. Volume and integration of various data makes education material quite voluminous, moreover the interaction between the tutor and the student at a personal level is a key characteristic of a good learning session. Therefore, the improvement in the internet protocols that have made it possible to transfer large amounts of data, multimedia and even hold chart sessions is an aspect of the development in the internet technology that has really had a positive impact on the development of e- learning. Security has been a key area of concern with regard to the development of internet and its usage (Tanenbaum, 2001). The well known protocols employed by the internet, the rapid rate of improvement in the internet technology that are hard to keep up with in terms of security protocols and the nature of internet, especially the aspect of an infinite number of potential access point and the lack of a body that is charged with the implementation of policies that govern its usage, are some of the factors that have made the realisation of internet security a designers nightmare (Keeton, 2002). The number of conmen operating in the net is considerable and thus security has always been an issue. The protocols employed by the recent versions of browsers make it possible to integrate security devices or software that increases the level of security. The use of firewalls and implementation of good security mechanisms by most internet providers has in a way developed some sense of security in internet usage. Security in an education system aids the smooth flow of information to the students. Furthermore, the emergence of electronic payment methods that implement watertight security mechanism has made it possible to transfer money from one corner of the globe to the other in a matter of seconds without having to worry so much about it finding its way into someone elses hand (Kwok-Wing, 2001). A secure system is surely a psychological boost to the student and will thus promote learning and transfer of money between the knowledge seeker and provider. The use of computers depends on three major components: Hardware, user and software. Considerable improvements have been noted in all the three areas over the years and are seen as some of the factors that have made it easy for the transfer of data over the internet and the use of such data by the intended end user. The hardware in computers refers to the physical parts that make up the computer system. Some of the hardware in a computer system is the monitor, mouse, keyboard, hard disk and RAM. Initially computers used to cover large spaces and had large power consumption rates (Thelin, 2004). The current generation of computers are built under the consideration of convenience, performance and user friendliness.

Investigate the rate of reaction between Calcium Carbonate and Hydrochl

Investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid at different concentrations Aim: To Investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid at different concentrations. Background Knowledge: I know from my knowledge of science, that by adding together a carbonate and an acid, that a salt, water and Carbon Dioxide are produced. Therefore in order to measure the rate of reaction, one of these products needs to be measured, and the rate at which it is produced can be used to define the rate of the reaction. The methods that can be used are either to measure the mass of the solution at intervals. Or to measure the produce of gas (Carbon Dioxide). Prediction: Using the known formula: ACID + CARBONATE SALT + CARBON DIOXIDE + WATER I can predict the reaction of my experiment to be: HYDROCHLORIC + CALCIUM Ã   CALCIUM + WATER + CARBON ACID CARBONATE CHLORIDE DIOXIDE The Chemical Formula is listed below: 2HCl + CaCO3 CaCl2 + H20 + CO2 I think that as the molarity of the acid goes up, the amount of gas produced will also go up. I have based this on my knowledge that calcium carbonate does not react in water. Therefore in solutions with little acid and more water, the calcium carbonate will not react as much as it would in pure acid for example. To make each of the different strengths of the acid, water is added to a solution of 2M hydrochloric acid. Therefore in the 0.2 value, there will be a lot of water, and so it is not expected that much gas will be produced. My predicted graph shows what I expect. On the x-axis, as the molarity increases, the gas produced on the y-axis does likewise. However there will be a point reached where the maximum limit of gas has been prod... ...a clear trend that as the molarity of the acid increases, the volume of carbon dioxide will also do the same. There is an even trend going up, with a straight line to fit as the line of best fit. The reason for this pattern is the same as that that was made in the prediction. As the concentration of the acid increases, there are more HCl molecules and so there is more chance of the calcium carbonate molecules colliding with these and so reacting to form calcium chloride. With the reaction occurring more often, the products will form in a greater quantity and so more carbon dioxide is produced. This reflects the rate of the reaction on the graph and proves my prediction and its theory correct. Evaluation: As the experiment was computer generated, it simulated how the experiment would have been conducted. It accounted for human errors in all aspects of the expriment.

Support for Imperialism Declined From 1880-1902

In the late 19th Century, following on from the ‘Scramble for Africa', Britain continued the aim of expanding her empire through the process of imperialism from the period 1880 to 1902. ‘New imperialism’ is an expression used to demote a change in attitudes to empire in the last quarter of the 19th century. However imperialism is said to mean ’the wish to maintain the unity and increase the strength of an empire which contains within its limits various more on less independent states.’The reason for new imperialism was to reinforce the idea of a white self government; as well as to increase Britain’s empire, by 1900 Britain had taken control over 1/5 of the world’s land. However, it has to be noted that there were significant fluctuations in popularity during this period such as after the outbreak of the Second Boer War. The rapid expansion or empire came of a time when the electorate had been significantly widened. It also came at the t ime of the revolution of the popular press. Now printing techniques made newspapers, magazines and books cheaper and more commonly available.90% of the population are illiterate. Since many newspaper owners were staunch imperialists, many newspapers focused on imperial issues, as so many of the population was illiterate it could be argued that the idea of imperialism was mostly for those of the upper and middle classes; this is backed up by the fact that the working class resented the concept of imperialism as it was seen as a distraction from their work and wages. Support was particularly strong in upper-class public elite groups, such as the landed aristocracy, and among middle-class businessmen.There is, however, a debate about the extent to which the mass of the working class supported imperial ideology. Teaching the values of the empire was not continued. Imperial lessons were taught in the schoolroom, pupils would learn about the supremacy of the royal navy, the name of the co lonies and trade routes, schoolboys stressed patriotic themes. Frowning literacy amongst the young ensured that children especially boys – war the targets of a large range of magazines and novels produced in the 1890s and early 1900s.Many of the stories produced during  this period were set in distant parts of the British empire and were designed both to excite the imagination and to reinforce a sense of patriotism and duty, stories like this appeared in magazines such as Boys Own Paper, Chums, Pluck and Union Jack. It was during the 1880s that youth organisations with military style structures and patriotic, imperialistic values were first set up (boys brigade was set up in Glasgow 1883). One of the most popular forms of entertainment in the late Victorian and Edwardian period way the shows put on by music halls.These shows were designed to appeal to a predominantly the middle/upper class audience and many had a strong imperialistic and patriotic theme (the term jingoism, meaning ‘extreme patriotism’ came from a music hall song). British people living in the late 19th century were subjected to many indirect forms of indoctrination. Towns were full of billboards advertising products and services, which often used imperial images; thus increasing the appeal for the imperial message.Some of the most enthusiastic of such working-class demonstrations came during the Boer War of 1899-1902, this method of protest was known as mafficking. When news of the relief or Mafeking reached Britain in May 1900, there were huge demonstrations throughout the country. Some historians have argued against the view that the mass of the working class was fervent imperialists. Price, for example, many members of the working class volunteered to fight in the Boer war in an effort to escape poverty rather than because they supported the cause.Similarly, Peeling, argues that, just because music hall songs were jingoistic, it does not mean the audience fully support ed the views expressed as the presence of a product does not presume its acceptance. For some liberals there was the moral issue of using force to spread British international power. It was not until the Boer war the anti-imperialism gained a significant political voice. The Boer war was a turning point regarding support for imperialism as, it was the first time the brutality of Britain had been seen so vividly.Families were herded into concentration camps and approximately 110,000 were killed; from this we can see that the support for imperialism changed due to the impact it had on other people which ultimately led to a mass of loss support by the British public and politicians. From about 1880, Britain adopted a more aggressive form of imperialism and there was extensive support for this amongst and their extensive support for this amongst the British. Support was particularly strong within the conservative party and amongst the working classes.The working class was less easily co nvinced of the benefits of patriotism. The empire may have provided some employment but it did not lead to high pay and increasing prosperity. Economic issues were particularly significant in shaping enthusiasm for imperialism. Many elements of Chamberlain’s vision of a great global empire with Britain at the centre, they were taken up through the media and popular entertainments central to his thinking was the notion that Britain was helping the uncivilised and racially inferior native people this image appealed to the majority of people in Britain.In 1880 Gladstone became Prime minister; after winning the election in 1879 and therefore replacing Disraeli, the conservative. As Gladstone travelled throughout England highlighting his policies to the public, it is evident that his ambitions were that to be supported by the public. Furthermore we must recognise that Gladstone was one of the first politicians who saw the importance of speaking to the electorate;this was not only because times were changing but also because a higher percentage of the population were getting the vote as a result of the reform acts.An example of this would be the 1832 act which enabled women to vote. The 1900 general election, (Khaki) resulted in a conservative victory and a continuance of conservative rule. It appeared as I popular support lay with the government that had taken Britain into a war against the Boers. But there was considerable media coverage of the brutality of the war. The extensive international opposition to Britain’s methods weakened support for imperialism at home. Many working-class men volunteered for military service to escape poverty not because they wanted to show their patriotism.Also, several politicians mainly from the left did not agree with the concept of imperialism as to them it was just the preservation of capitalists. In conclusion, although there was a rapid increase in the support for imperialism due to the several sources such as bo oks, schools and entertainment in facilities such as music halls, from 1880-1902 the policy’s impression on the public began to change due to other factors such as because of the Boer war’s brutality as well as because of capitalists at the time who were seen as draining the countries resources.

John Browns Effect on World History - 866 Words

Since the publication of John Browns article in 1798, we have learned an enormous about ancient Egyptian history. Some of what we have learned (certainly not all) includes (1) the English alphabet can be translated into hieroglyphics, therefore a new era of Egyptology started and lead to wonderful discoveries, such as Tuts tomb, and the hieroglyphic burial content that surround sarcophagi and tomb walls are readable, as is the Book of the Dead and hieroglyphic writings such as autobiographies and chronologies; (2) the dates of the Pharaonic Dynasties and kingdoms (i.e., Old, Middle, and New) which are now much more firmly established; (3) that the ability to interpret he historical inscriptions on great monuments (e.g., Thutmose III†¦show more content†¦The identical text is carved into the black basalt stele fragment in three scripts: (1) Hieroglyphic; (2) Demotic; and (3) Greek. Considering what Herodotus tells us about life in ancient Egypt, it is certain that the rebirth of Egyptology in the 19th century is not entirely based on new knowledge, but rather the rediscovery or absence of what had already been known. Herodotus told us much about ancient Egyptian life in his histories. He was very clear about the purpose of the pyramids, as he quoted, Or rather to make the causeway the works on the mound where the pyramids stand in the underground chambers which Cheops intended as vaults for his own sepulcher. He also detailed extensively, the process of mummification, After the expirations of that space of time which must not be exceeded, the body is washed and wrapped round from head to foot, with bandages of fine linen cloth, smeared over with gum, which is used generally by the Egyptians in the place of glue, and in this state it is given back to the relations who enclose it in a wooden case which they have had made for the purpose, shaped into the figure of a man. Surprisingly, although Herodotus had been available to scholars for many centuries by the time John Brown wrote his article, neither mummification nor the accurate purpose of the pyramids is identified in John Brown Article.
