Revised Analytical about Poetry - Essay Example The study develops an understanding of the poetic approaches emphasized upon by a professor and his student in literature that are from different races. The poem theme for English B implicitly resembles an answer, written in the form of a stream-of-consciousness to the indirect question, what we can call true. The main theme of the poem and specifically in this context is the quest to look for answers in the issue of discrimination of people through color, race, and self-identification (Scott, 2006). The poem also analyzes the means and ways of dealing with this through the theme of English B analysis based on the instructor and his student’s work (Sherry & Schouten, 2006). The theme for English B analysis poem starts with a question from the student, twenty-two year old who is the only colored in his class and wonders if it would be that simple to write a page out of him that could be considered true. Therefore, the student has received an assignment to write about something that would be true, but he asks himself if it would be that simple. This question could have a dual meaning for example, if writing the task would be an easy task or not and on the other hand, if a complicated notion of truth could be easy to gather from the poem (Leach, 2004). The poem though gives answers to both questions but as for the latter, the answer has been given in the form a thread penetrating the whole poem. For example, the poem starts with ‘I wonder if it is true’(line 6) then an answer is alluded which says it is not easy for me to know what is true for me(line 16) and then the thread is concluded with ‘but we are, that’s true’(line 36). Harlem was the center of development and prosperity of Africa American community in the period of Harlem renaissance. Though Harlem was based in New York, it has been known to be associated

IEEE 802.11 Research Paper Example | Topics and Well Written Essays - 1000 words

IEEE 802.11 - Research Paper Example Wireless uses radio waves in the transmission. Wireless LAN deals with two lower layers of the Open System Interconnection (OSI) which are the physical and data-link layers. I will briefly discuss three physical specifications of the physical layer: 802.11b: 802.11b was released in 1999 and uses DSSS that provide higher bit rate. The transmission of the data can reach 11 Mbps. It operates in 2.4 GHz range. 802.11a: 802.11a was released in 2001 and uses OFDM. The transmission of the data can reach 54 Mbps. It operates in 5 GHz range 802.11g: 802.11g uses OFDM. The transmission of the data can reach 22 Mbps. It operates in 2.4 GHz range. (21) IEEE 802.11 Security: 7 Wired Equivalent Privacy (WEP): IEEE released Wired Equivalent Privacy protocol what is known as WEP for the security 802.11 standard in 1990 (15) .WEP was designed to make the communication through wireless safe and secured as much as it is in the wired local area network. WEP provides authentication and confidentiality to the security of the wireless network (21). WEP was developed on the base of RC4 stream cipher. In the encryption and decryption the same secret key must be used (1). The wireless device and the access point must have the same secret key (4). ... The process of WEP authentication is as shown in the figure: Retrieved from VoCAL (2012). The figure is taken from this website: http://www.vocal.com/secure-communication/wired-equivalent-privacy-wep/ 1. The authentication is sent from the wireless station to the access point. 2. The access point responds with challenge text sent to the wireless station. 3. The wireless station encrypts the challenge text and then sends it to the access point. 4. Finally, â€Å"If the access point can decrypt the authentication request and retrieve the original challenge text, then it responds with an authentication response that grants the client access† so the secret key in both sides should match each other. (11) The encryption of the data that are transferred between the wireless station and the access point in the WEP uses RC4 stream cipher. The process of WEP encryption is as shown in the figure: WEP uses CRC for the data integrity. WEP performs CRC (Cyclic Redundancy Check) checksum ope ration on the plaintext and generates CRC value. This CRC value is concatenated to the plaintext. The secret key is concatenated to the Initialization Vector (IV) and fed into the RC4. Based on the secret key and IV, RC4 generates key stream. The key stream and plain text + CRC message is XOR'ed together. The result is the cipher text. The same Initialization Vector that was used before is pre pended in clear text to the resultant cipher text. The IV + Cipher text along with the frame headers are then transmitted over the air. (13). The shared key in WEP never changes again, and it is used for authentication and encryption which is the problem (13). WEP problems: The major problem in WEP in terms of security is that the wireless
