  • A Look At Public Key Encryption - 1,210 words
    A Look at Public Key Encryption Encryption is the process of disguising information by transforming plain text into gibberish, or ciphertext, which cannot be understood by an unauthorized person. Decryption is the process of transforming ciphertext back into plaintext that can be read by anyone. Example of encryption can be found in history, for example in the era of the Cold War, the Solviet Union and the United States would send electronic messages to one military point to another, encrypted. If the enemy intercepted the message, they would have to crack this message to get the information. Typically when governments used encryption they used a very complex method of encrypting messages. E ...

    A Quantum Computer... a future technology Mike Damewood By the strange laws of quantum mechanics, Folger, a senior editor at Discover, notes, an electron, proton, or other subatomic particle is "in more than one place at a time," because individual particles behave like waves, these different places are different states that an atom can exist in simultaneously. Ten years ago, Folger writes, David Deutsch, a physicist at Oxford University, argued that it may be possible to build an extremely powerful computer based on this peculiar reality. In 1994, Peter Shor, a mathematician at AT&T Bell Laboratories in New Jersey, proved that, in theory at least, a full-blown quantum computer could factor ...

  • Cable Modems: Cable Tv Meets The Internet - 3,910 words
    ... downstream traffic travels through the cable modem's Media Access Control mechanism. The MAC mechanism's functions are fairly complex. The MAC mechanism's main purpose is to implement MAC protocols under the direction of the CMTS. MAC protocols are used to time-share the cable media among the various cable modems in a cable data network. The MAC processes can be implemented in hardware, or a combination of software and hardware. Both the CMTS and the MAC mechanism implement MAC protocols to perform ranging procedures to compensate for cable media delays and line losses. The CMTS also interfaces with the MAC mechanism in each cable modem to assign upstream frequencies and upstream time s ...

The storage and retrieval of data interacts in many ways. In most instances computerised data is obtained from paper based information. An example of this is the wages system. On a daily basis, a member of the management team would verify that staff has attended work and take note of the hours, unless there is a clocking in machine. At the end of the week, the total hours worked by each employee would be calculated along with any overtime and bonus. This information is then entered into the organisations computer system. When this task is compl ...

    ... f destroying computer data. Although the system as a whole might be devastated, the data can sometimes be restored through special techniques. Crimes using computers are more prevalent. There are numerous crimes that can be committed using computer, but they are not new crimes. The crimes were already in practice before it's invention but new technology makes them easier to commit and provides less of a chance of getting caught. Money is the root of a lot of crimes, for instance, embezzlement is "the act of stealing money that is entrusted to you"(1), or stealing from somebody that you work for. Banks are one of the best places to steal money from because, obviously, that's where a large ...

  • Electronic Commerce - 1,116 words
    Electronic Commerce Electronic Commerce Introduction: As the internet grows in popularity every day, so too does electronic commerce. Electronic commerce, simply put, is the exchange of money for goods and services via electronic means. In other words, electronic commerce is usually when you purchase something off of the internet. Electronic commerce is often referred to as e-commerce, or e-business. In this paper I will be discussing the technical side of e-commerce, security, different points of view regarding e-business, and of course my personal opinion and experiences. Background Information: First I would like to discuss the types of e-business. E-business can be anything from purchasi ...

  • Encryption - 713 words
    Encryption The electronic age has brought forth many technological advances. With these advances came the need for security and tighter control on how we send information electronically over the Internet or through a network. Date encryption is, in its simplest terms, the translation of data into a secret code. In order to read an encrypted file, the receiver of the file must obtain a secret key that will enable him to decrypt the file. A deeper look into cryptography, cryptanalysis, and the Data Encryption Standard (DES) will provide a better understanding of date encryption. Cryptographic Methods There are two standard methods of cryptography, asymmetric encryption and symmetric encryption ...

    Government Intervention On The Internet Introduction During the past decade, our society has become based solely on the ability to move large amounts of information across great distances in a very short amount of time and at very low costs. The evolution of the computer era and our growing need for ultra-fast communications has caused a global network of interconnected computers to develop, commonly referred to as the Internet or the world wide web. The Internet has influenced practically everyones life in some way whether it was done directly or indirectly. Our children are exposed to the Internet at school, and we are exposed to the Internet simply by just watching our television sets. Th ...

    Mathematical Codes Mathematical Codes Mathematical codes are used by millions everyday for a variety reasons, but all intending to keep something private. The coding theory has actual applications in consumer electronics and with other areas of mathematics. Encryption, which involves enciphering and encoding, is used to protect data against organized crime, government and multinational institutions. A use of arithmetic, prime numbers, and prime factorization is used within coding theory. The study of enciphering and encoding, and deciphering and decoding is called cryptography (Gardner 17). Encryption is encoding or enciphering a message so that the contents are hidden from outsiders (Frsen ...

Network users are able to share files, printers, and other resources; send electronic messages; and run programs on other computers. A network has three layers of components: application software, network software, and network hardware. Application software consists of computer programs that interface with network users and permit the sharing of information, such as files, graphics, and video, and resources, such as printers and disks. One type of application software is called client-server. Client computers send requests for information or requests to use resou ...
