Pupils delight in the wealth of opportunities for understanding more Essay

Pupils delight in the wealth of opportunities for understanding more about the world - Essay Example Geography is a subject that investigates the shared interactions amongst human beings and the environment. Therefore, it is correct to say that environmental issues are the subject matter of geography. As a subject, geography looks into the ways in which the natural environment is used in terms of human actions towards the biosphere, atmosphere, lithosphere and hydrosphere. Such actions impact the issues relative to the environment, such as vegetation coverage, land usage, water resources and renewable sources of energy. This paper will examine the significance of history and geography for students in relation to an event such as The London Evacuations during World War II. The most significant learning from the London evacuations that became unavoidable during World War II pertains to improving people’s judgment, which is why many scholars and leaders have held that schooling in the modern world should be primarily historical (Streatfield, 2000). Commenting on the education pr ocess in the newly set up democracy in the US, President Jefferson had correctly remarked that â€Å""the people are the ultimate guardians of their own liberty. History by apprising them of the past will enable them to judge of the future. It will avail them of the experience of other times and other nations; it will qualify them as judges of the actions and designs of men" (Jefferson, 1998, p.121). History does not provide answers to questions that come to our mind but assists us in getting to know how we can make better decisions in the future. After getting to know of the London evacuations during World War II, students realize the hardships faced by people and the blunders that were made in terms of causing immense suffering to millions of people. Such events particularly enlighten students and make them to think as to why they occurred and whether they could be avoided (Krug, 1967). In understanding the shortcomings of becoming party to such destructive happenings, the coming generations will have a clear viewpoint of the sufferings and will never repeat the same mistakes again. In studying the events that led to the Second World War, students are forced to think after growing up that the historical events that led to loss of life and to hardship for majority of the people should not occur again. In this context, enough evidence exists to indicate that there is a common agreement about the working of cognitive psychology. People capable of thinking independently believe that history supports common cultural understandings and dialogue. The London Evacuations during World War II create a need for identity that is vastly related with ideas of mutual cultural understandings. It is also recognized by many that issues of identity are the main concern in psychological studies and it has been found that losing identity leads to loss of the sense and of importance, which is exactly what The London Evacuations during World War II led to. History or memory of the past is of great importance in the creation of individual identity (Mink, 1969). Geography too is equally important in making meaningful contribution towards understanding human experiences relative to the natural environment. A major strength of geography is that it relates to both physical and social sciences. The subject promotes values, skills and cognitive procedures and assists students in

The Pros and Cons of Using Encryption as a Key Technological Solution Essay

The Pros and Cons of Using Encryption as a Key Technological Solution to Corporate Security - Essay Example Moreover, the encryption can be employed to offer high level security to e-mail, network communication, data and information stored on hard drives or any portable or mobile disks, as well as other information that necessitates safety (Cook, 2000). This paper discusses some of the main areas and aspects of encryption and its main applications, organizational implications and the evolution of old and current practices. Application of Encryption Encryption is technique of translation of information and data into a clandestine code. Additionally, the technique of encryption is the most efficient method to assure data security. In this way, to interpret an encrypted file, we should have access to a password or else secret key that facilitates us to decrypt it. Unencrypted information as well as data is known as plain text; hidden or encrypted data is known as cipher text (Webopedia, 2010). An unbelievable development of the Internet has energized companies as well as customers in a simila r way through its assurance of altering the means we subsist and work. It is very simple to purchase and sell goods all through the world using a computer or laptop. However safety and security is a main distress on the Internet, particularly when we are utilizing it to transmit sensitive data and information among diverse groups of people (Tyson, 2010). In case of Encryption techniques we need to encrypt a huge number of secret information and data. For example in case of web based business or corporate data transfer we need some sort of sensitive and high value information like credit-card information, confidential communication, social security information, susceptible business details, personal details and bank-account information. In this scenario, the information security is offered on computers and over the Internet through a multiplicity of techniques. An easy and straightforward security technique is to simply put sensitive information on removable storage media similar to moveable pen drives or peripheral hard drives. However the majority well-liked types of safety the entire depend on encryption, the procedure of hiding and encoding data and information in such a manner that just the person (or computer) that has the decoding key is able to decode the message (Tyson, 2010). Evolution of Encryption In its first kind, people have been trying to hide certain data and information that they desired to keep in their own control through alternating parts of the information by means of signs, pictures as well as numbers. Earliest Babylonian merchants employed intaglio, a part of plane stone engraved into a collection of images as well as a number of writings to recognize them in trading matters. However, through this method, they are creating what these days we recognize as 'digital signature.' The people are acquainted with that a specific 'signature' having relation to this merchant, however just he had the intaglio to generate that specified signature. C ertainly, technology nowadays has developed at such fast swiftness that requires caring for information develops by decreasing the dependability of older encryption
