Ascii Code

Samuel Mercuri MGF 1107 Pickle Project 7 Computers do not recognize letters, text, or words. They only deal with numbers. To get computers to work with text, we have to represent each character as a number. The text files you read and write are actually stored, loaded into memory, and transposed into numbers. When the file is shown on your screen, the numbers are transposed again into letters and text. The first 31 ASCII codes control commands, or non printable characters that control how the data will be interpreted. ASCII is a computer code originally based on the letters of the English alphabet.It is an acronym for American Standard Code for Information Interchange and is used to represent text in computers, communications equipment, and texting devices. Each letter and number is given an ASCII code. Certain commands are also given an ASCII code. For example, the ASCII code for A is 65, and the ASCII code for 4 is 52. Work on the ASCII code started in 1960, and in 1968 President L yndon B Johnson mandated that all computers purchased by the United States government support ASCII code. Computers use ASCII code to communicate with each other. http://www. ascii-code. com/The following table shows the ASCII code for letters, numbers, and commands. The ASCII code for the word â€Å"Bears† would be: 66 101 97 114 115. Note that the ASCII code is different for uppercase and lowercase letters. B: 66 e: 101 a: 97 r: 114 s: 115 By the same token- the code: 68 105 115 110 99 121 would read â€Å"Disney† once transposed. 68: D 105: i 115: s 110: n 99: e 121: y You could see these as an example of how we use our computers to communicate. We type letters and words, the computer transposes them into a code that it can understand and sends it to your friend’s computer.Your friend’s computer understands the code and transposes it back into text so your friend can read what you wrote.

Let’s say Program A can’t convert its data to the format of program B. But if both programs can input and output ASCII code, then the conversion may still be possible. Most e-mail transmissions are limited to ASCII characters.Because of this, it is not possible to use special formatting such as Italics or underlines. This is also why graphic files, music, spreadsheets, or documents with non ASCII characters in them must be sent as attachments to the e-mail. When they reach their destination, they will be â€Å"decoded† for use. http://www. telacommunications. com/nutshell/ascii. htm These words come together to make sentences. So for example: â€Å"Who let the dogs out? † would look like this: 87 104 111 32 108 101 116 32 116 104 101 32 100 111 103 115 32 111 117 116 63 87 104 111: Who 2: space bar 108 101 116: let 32: space bar 116 104 101 : the 32: space bar 100 111 103: dogs 32: space bar 111 117 116 63: out? Some people will even use ASCII code to draw pictures called â€Å"ASCII art†.

Examples of ASCII files would be . txt, . asp, . html, and . php. Binary code is used to transfer raw data such as music, vide os, or pictures.If someone tries to decode a document containing such raw data using ASCII, they will probably get a response that the file is corrupted. There are programs online that can transfer between ASCII code and binary code. http://www. coreftp. com/docs/web1/Ascii_vs_Binary_transfers. htm There is also an upper case ASCII table which is not officially recognized. It tends to vary based on the computer or font being used. Some characters in this table are more common than others.

An Introduction To Encryption And Decryption

An Introduction To Encryption And Decryption CHAPTER 1 This thesis proposes a VHSIC Hardware Description Language (VHDL) design of Encryption and Decryption Algorithm for Data. In this chapter, the challenges of cryptography is firstly presented. This chapter also briefly discusses the problem definition, scope of work and the thesis objectives are also highlighted.Finally, the chapter end with the chapter organization. The dissertation presentation is provided at the end 1.1 An introduction to Encryption and Decryption, a type of cryptography Encryption and Decryption, a type of cryptography, refers to the process of scrambling information so that the observer cannot be detecting the data. Cryptographic key is a piece of data used to encrypt or decrypt to plaintext. (Alex Brennen V., 2004) The Crypto, from the word cryptographic mean is it has its origins in the Greek word KRUOTOS, which means hidden. Thus the objective of cryptography is to hide information so that only the intended recipient can read it.[2] . Cryptographic is a protocol or method of performing encryption and decryption (Alex Brennen V., 2004). There are two types of cryptographic: symmetric and asymmetric key. Figure 1.1 is example a symmetric cryptographic has a single key, which is used for both encrypting and decrypting information. Data Encryption and Decryption is a well-known example of symmetric cryptographic. In symmetric cryptographic, public-key cryptographic uses complementary pair of keys to divided the process of encryption and decryption. This process is shown in Figure 1.2. This part is discuss about the symmetric-key cryptographic only.[3]. The proposed projects is to create the algorithms where it is use to convert of information, rearranging the original massage produce output referred as ciphertext Plaintext Plaintext Ciphertext Key Figure 1.1: Symmetric Cryptographic Plaintext Plaintext Ciphertext Encryption Key and Decryption Key Figure 1.2: Public-Key Cryptographic 1.2 Problem Statement At present there are many encryption and decryption, especially in the communication system provided in a variety of application. Encryption and decryption is particularly impacted in the field of military communications and reliable security data to protection for transmitting. This ciphertext is used in the military is to send information such as direction, strategy, secret codes and other information that can not be know by the national foe during the war.[4] Creating this system is the process by which information can not be detect by the national foe. The information can not be recognizing by the national foe because this system is using the process to encrypt data and decrypt data. [4] 1.3 Scopes of Work Based on available software resources, limited time frame and expertise, this research project is narrowed down to the following scope of work: 1. The project is only to design fixed 64-bit input of data block size, 64-bit output of data block size and 56-bit of key size based on an Encryption and Decr yption algorithm . 2. The projects is limited to design, to synthesis, to simulate and to verify the design in Altera Quartus II software. Objective The project are to create a system that can protect electronic data (secret information) which Consist of encryption and decryption process and to fully design an encryption and decryption algorithm using VHDL. The objectives of this project are

Global financial crisis and its effects on Nokia Company Assignment

Global financial crisis and its effects on Nokia Company - Assignment Example On one side, many people believed those responsible for the crisis were the ones receiving bailouts, whereas on the other end, the worldwide financial problems were to affect the livelihoods of almost every individual on the planet due to global interconnection. The subprime turmoil came about in large potion due to the financial tools such as securitization used by banks (Sheila, 2008: 20). Through securitization, banks would pool some of their loans into sellable assets. In so doing, they off-load the risky loans onto others. For this matter, banks knew they would make millions of cash through money-earning loans. However, these money-earning loans tied up for decades, therefore, banks turned them into securities. Security buyers received payments regularly from all mortgages. As a result, the U.S. banks off- loaded their risks. Upon testing this instrument, financial gurus saw securitization as perhaps the greatest innovation of the 20th century. With economic slump entrenching it s effects into the global economy, the divisions of the Nokia including telecommunication and mobile phones division started backing up the pillars of Nokia. In spite of the global deep recession, Nokia grasped potential, quickly came to its feet, and soon started streamlining its business. Financial crisis affected most financial institutions. However, as the securitization business continued buoying, high street banks got into a form of investment banking where they bought, sold, and traded risks. Same investment banks not contented with trading risks, selling and buying, they ventured into home loans and mortgages while they lacked the right management and controls. Many banks took huge sums of money inform of loans thus increasing their... This paper seeks to address the global issue of the financial crisis unfolding, and tries to consider the effects the crisis had on money lending institutions. Also, the change in the financial state of Nokia company is being considered against the background of the crisis. The subprime turmoil came about in large potion due to the financial tools such as securitization used by banks . Through securitization, banks would pool some of their loans into sellable assets.

Financial crisis affected most financial institutions. High street banks got into a form of investment banking where they bought, sold, and traded risks. Same investment banks not contented with trading risks, selling and buying, they ventured into home loans and mortgages while they lacked the right management and controls. Many banks took huge sums of money in form of loans thus increasing their exposure to financial problems. When people eventually began noticing the risk, their confidence fell down at an alarming rate. As a result, the level of lending slowed down at once and in other cases ceased . September 14, 2008 witnessed Lehman Brothers collapse. Following its collapse, governments worldwide struggled to rescue their gigantic financial institutions as the state of the failing stock and housing sectors persisted. In conclusion, global financial crisis was inflicting and driving even the developed economies bankrupt.

Equalization in Canada verses Equalization in Australia Essay

Equalization in Canada verses Equalization in Australia - Essay Example Equalization is one of four major federal transfer programs. The others are the Canada Health Transfer, the Canada Social Transfer, and the Territorial Formula Financing (the main source of revenue for territorial governments). Equalization is the federal government's main device for reducing fiscal inequalities between the 'have and have-not' provinces (Mapleleafweb). The grant to receive equalization funding is calculated by a formula assessing each province's revenue raising ability against a five-province standard. Presently eight Canadian provinces receive equalization: Quebec, Nova Scotia, Newfoundland, British Columbia, Prince Edward Island, Manitoba, New Brunswick, and Saskatchewan. This program is the Canadian government's most important initiative for reducing fiscal discrepancies between provinces (Equalization Program). Equalization payments allow less prosperous provincial governments to offer their residents public services such as hospital fees, electricity, water and other basics that are comparable to those in other provinces and at similar taxation levels. Each province receives unconditional equalization payments. ... For 2005-06 eight provinces are expected to qualify for $10.9 billion in equalization entitlements. The provincial governments may spend the equalization money they receive in any way they desire, unlike conditional transfer payments such as the Canada Health and Social Transfer. The equalization payments guarantee equal levels of health care, education, and welfare in all the provinces. Equalization payments do not involve payment transfers from wealthy provinces to poorer provinces. Instead the federal treasury provides the funds for these payments. In other words, for example, a wealthy citizen from a poorer province like New Brunswick, pays more into equalization than a poorer citizen in wealthy province like Ontario. Since Ontario has a bigger population and wealth, the citizens of Ontario as a whole pay more federal taxes and therefore their total contribution in equalization payments is greater than that of New Brunswick. Equalization payments also aid by encouraging national unity. Quebec, the most populous of the poorer provinces, is the largest single beneficiary of the payments. 70% of the 10 million Canadians of the poorer provinces reside in Quebec when British Columbia and Saskatchewan are removed. The history of Equalization dates back to Confederation and the Constitution Act of 1867. Two basic principles that Canada's founding fathers based the separation of legislative powers: 1) The central government must retain much of its revenue generating power for the purpose of building railroads 2) 'Coordinate federalism' in which provincial governments act independently and autonomously within predefined powers and must be the basis for the division of powers between provinces and the central government. The great

Buddhism Essay Example | Topics and Well Written Essays - 750 words - 13

Buddhism - Essay Example Atman can be seen as a particle of the universal soul (Brahman), which lives in each person. In turn, Buddhism denies such understanding of the soul and its varieties. Unlike Hinduism, Buddhism does not regard the human soul as an unchanging essence, because for Buddhism the soul is a flow of human experiences, feelings and sensations. Such an understanding seriously affects the idea of ​​rebirth that is represented in Hinduism and Buddhism: in Hinduism, reincarnation implies that the constant soul changes its body, while Buddhism focuses on the fact that it is about the rebirth of the soul, the resumption of its existence. Despite the contradiction between the different versions of Hinduism, they all share certain fundamental ideas (Whitman 608). According to the general Hindu notions, beyond the volatile physical world there is a single universal, unchanging, and eternal spirit called Brahman. The soul (Atman) of each being in the universe, including the gods, is a part of that spirit. In fact, â€Å"Hinduism believe in the existence of Atman, that is the individual soul and Brahman, the Supreme Creator† (Nandan and Jangubhai 30). The soul is regarded as an eternal and immutable essence, which has the opportunity to live after human death. When the flesh dies, the soul does not die, for it passes into another body, in which it has a new life. The fate of the soul in each new life depends on its behavior in previous incarnations. The law of karma says that no sin is left without punishment and no virtue - without reward; if a person has not received the deserved punishment or reward in this lif e, he/she will get them in one of the following. Human behavior determines the higher or lower status of the later incarnation (Nandan and Jangubhai 27). Though Buddhism and Hinduism share the concept of rebirth, the Buddhist concept differs in details from the Hindu one. The doctrine of rebirth presented in Hinduism involves a permanent soul, the essence of

What higher food prices mean for both consumers and producers at your Essay

What higher food prices mean for both consumers and producers at your own country Which are the factors that drive the food prices higher What, and for whom, are the costs and benefits of such an increase - Essay Example Consequently, the producers’ increases food prices to the consumers so that they can manage continuous food production. This paper will discuss the impacts of increasing food prices to both the producers and consumers. Additionally, it will discuss the factors that drive the food prices high and what or for whom, the cost and benefits of such increase are. Increase in food prices may affect producers positively or negatively. High food prices may affect the demand of food negatively. When the food prices goes high, the demand may go low since consumers may decide to go for cheaper substitutes or may decide to entirely forego that kind of food. For instance, increase in soft juice prices, meat and juices reduce their consumption, since people will opt for alternative food that is cost friendly2. On the other hand, producers may benefit directly from the high prices of food since they will be making more profit. Food prices hikes due to increase in demand hence producers will be able to produce in bulk which will also earn them a lot of sales which in turn increases their profits. To the consumers higher food prices have detrimental effects since some people will be spending more money on food in such a way that they will not have money to spend on non-food items. People who are below average financially, might not afford some food if the prices are hiked hence they might opt to skip some meals which is dangerous to human health. Additionally, the chronic diseases will be in the rise since consumers cannot meet the required dietary needs3. Most people will buy food for general satisfaction without looking into the nutritional value of food. High food prices interfere with the consumer preference. If the consumers visits the market and find that the preferred food is expensive than usual, they shift their preference towards the

International Business Risks Essay Example | Topics and Well Written Essays - 2000 words

International Business Risks - Essay Example Sales Convention and UNIDROIT Principles of International Commercial Contracts are quite prominent. For the understanding of the international business the legal system of a country is essential, as the business practices of a certain county are being regulated by its laws. These business regulations set out the ways in which the business transactions are to be carried out and also define the liabilities and privileges to the parties involved in the transaction (contract). There are broadly four basic legal systems that are being practiced around the world. Firstly it is the Islamic Law, secondly the Common Law, thirdly the Civil or Coded Law, and lastly the Marxist Legal System. They are discussed as follows: The Islamic law is developed from the interpretation of the Holy Book Quran Majeed and the Hadith i.e. practices of the Prophet Mohammad P.B.U.P. The philosophy of law in Islamic community is greatly different from the one that is practices in the Western Countries. One the most important aspect of the Islamic law is the undesirability of payment or receipt of interest. This prohibition of interest had also largely influenced the business and banking practices, though, the sanctity of contracts, risk sharing, individual's rights and duties, and property rights are welcomed. Moreover, investments in casinos, gambling and alcohol are strictly prohibited. Due to the restrictions discussed above, ... Instead of money borrowing, businesses have evolved to rely on leasing arrangements for the acquisition of fixed assets. In case of banks largely in Iran and also Pakistan fixed service charges are being charged rather than the interest charge, while the depositors on the other hand are being provided with shares rather than interest payments. (Aswathappa, 2003) 2. Socialist Law This system of law has developed from the Marxist socialist system and is being practiced in the former communist countries in some or the other forms. A crucial is being played by ideology. In contrast to the civil law code those are being incorporated by governments of different point of views, the socialist codes are meant for the societal and personal transformation. This system is not a decided set of rules, but actually intends to attain a Communist society. China and Russia are the two countries which come to ones thought when talking of Communism. As there is no set of rules, both of the countries have adopted dissimilar paths for their respective economic and political development. 3. Common Law The fundamental principles of the Common law come from the English law. The common law has evolved over the years from the collective opinion of the judges and from decisions given in individual cases. A majority of commercial law such as contracts, agency and torts are construed from the principles that emerged from individual quarrels that were resolved in antagonist procedure. One of the key aspects of the common law is this that it is being maintained that similar decisions should be given out for similar cases. Due to this reliance on the decisions of the earlier cases enables the businessmen to shape
