Managing Information Systems In Organizations Essay

Managing Information Systems In Organizations INTRODUCTION In recent years, there has been an abundance of new technologies in the information systems field. These new technologies have altered the very development process itself. Information systems have gone from being a series of one level databases to three dimensional reality, virtual reality, and multimedia systems. In the early days of information systems, the demands were for data, with no real function of artificial intelligence. However, as the 21st century approaches, business has taken on an entirely different function, and the need for individual information systems has grown immensely. This demand for information technology is in all areas of business: corporations,†¦show more content†¦Data models were used for the first time to describe physical structures from a logical point of view. With this distinction between the logical and physical information, value systems were developed which could integrate all the data of a given application into one collection. The fourth generation consisted of relational databases and began in the 1980s, resulting in database systems that could store data redundancy free under a central control and in a clear distinction between physical and a logical data model. Systems based on relationship modeling occurred during this period of time. The systems based on relationship modeling are provided with a high degree of physical data independence and the availability of powerful languages. Less of the system is visible to the user, with changes taking place in the background. A shift from record orientation to set orientation marks this fourth generation. As of 1991, there was a fifth generation predicted, post-relational, which we are currently experiencing, and perhaps surpassing. Other applications can benefit from database technology. The development of extensible systems, logic-oriented systems, and object-oriented systems are part of this generation. R.G.

THE CONVERSION J. Neil C. Garcia (b. 1969) It happened in a metal drum. They put me there, my family that loved me. The water had been saved just for it, that day. The laundry lay caked and smelly In the flower-shaped basins. Dishes soiled with fat and swill piled high in the sink, and grew flies. My cousins did not get washed that morning. Lost in masks of snot and dust, their faces looked tired and resigned to the dirty lot of children. All the neighbors gathered around our open-air bathroom. Wives peered out from the upper floor of their houses into our yard. Father had arrived booming with his cousins, my uncles. They were big, strong men, my uncles. They turned the house inside-out looking for me. Curled up in the deepest corner of my dead mother’s cabinet, father found me. He dragged me down the stairs by the hair into the waiting arms of my uncles. Because of modesty, I merely screamed and cried. Their hands, swollen and black with hair, bore me up in the air, and touched me. Into the cold of the drum I slipped, the tingling too much to bear at times my knees felt like they had turned into water. Waves swirled up and down around me, my head bobbing up and down. Father kept booming, Girl or Boy. I thought about it and squealed, Girl. Water curled under my nose. When I rose the same two words from father. The same girl kept sinking deeper, breathing deeper in the churning void. In the end I had to say what they all wanted me to say. I had to bring this diversion to its happy end, if only for the pot of rice left burning in the kitchen. I had to stop wearing my dead mother’s clothes. In the mirror I watched the holes on my ears grow smaller, until they looked as if they had never heard of rhinestones, nor felt their glassy weight. I should feel happy now that I’m redeemed. And I do. Father died within five years. I got my wife pregnant with the next. Our four children, all boys, are the joy of my manhood, my proof. Cousins who never shed their masks lay them for all their snot and grime. Another child is on the way. I have stopped caring what it will be. Water is still a problem and the drum is still there, deep and rusty. The bathroom has been roofed over with plastic. Scrubbed and clean, my wife knows I like things. She follows, though sometimes a pighead she is. It does not hurt to show her who is the man. A woman needs some talking sense in to. If not, I hit her in the mouth to learn her. Every time, swill drips from her shredded lips. I drink with my uncles who all agree. They should because tonight I own their souls nd the bottles they nuzzle like their prides. While they boom and boom flies whirr over their heads that grew them. Though nobody remembers, I sometimes think of the girl who drowned somewhere in a dream many dreams ago. I see her at night with bubbles springing like flowers from her nose. She is dying and before she sinks I try to touch her open face. But the water learns to heal itself and closes around her like a wound. I should feel sorry but I drown myself in gin before I can. Better off dead, I say to myself and my family that loves me for my bitter breath. We die to rise to a better life. How to cite Humalit Poems – Torres, Essay examples

Networking Models In Flying Ad Hoc Networks â€Myassignmenthelp.Com

Question: Discuss About The Networking Models In Flying Ad Hoc Networks? Answer: Intorducation Worldwide Interoperability for Microwave Access (WiMax) refers to the delivery of services to long mile wireless broadband access (Bernardos et al., 2014). It provides both multipoint and applications. It has able to improve the network security during transmission to last mile. WiMax uses three data encryption standards for protecting the data and information. WiMax uses Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) to encrypt all traffic on its network (Makris, Skoutas Skianis, 2013). The data encryption standards used by WiMax is described as below: Triple DES used to implement original Data Encryption Standard (DES) algorithm, hackers used for figuring out how to vanquish effortlessly. Triple DES was important standard and most used symmetric algorithm in organization (Osseiran et al., 2014). Triple DES uses three different keys that are 56 bits each. The key length is 168 bits; researchers would suggest that 112-bits in key quality is more similar to it. The Advanced Encryption Standard (AES) is algorithm trusted as standard by the U.S. Government. It is used in 128-piece frame. AES uses keys of 192 and 256 bits for encryption purposes (Sahingoz, 2014). It is used in many cases in the organization for providing security to the data and security of the business organization. RSA is a key encryption algorithm and standard for encrypting transmitted on Internet. RSA is used as an asymmetric algorithm because of its uses of a couple of keys (Viani et al., 2013). The key is an algorithm that is use to encrypt message. There is a private key to decode it. The limitation of RSA encryption is a data that takes aggressors a lot of time. The two examples of WPAN technologies are Bluetooth and Zigbee. There are various security challenges in the Bluetooth devices and technology. There are various attacks against confidentiality and data integrity (Ayyash et al., 2016). Bluetooth does not provide native client verification. The authorization of the Bluetooth device is not done that causes explicit behavior of other connected devices. There is a huge threat of DoS attacks on the Bluetooth devices during transmission of data and information. There can be malicious entry of external parties during the transmission process of data and information. The sensitive data and information might be damaged and corrupted during the wireless transmission. Bluesnarfing is a threat to this technology that allows the attackers to increase the use of the Bluetooth enabled devices. It looks for the IMEI number of the Bluetooth devices and get connected through this. After connecting with the parent Bluetooth devices, the connected device breaches all the data and information from the Bluetooth device. Bluejacking causes data breach from the Bluetooth enabled mobile phones. The attacker starts the bluejacking by sending false message to the mobile phones (Jiang et al., 2017). These span messages and phishing mail causes damage to the mobile phones. ZigBee is a wireless communication with low power and low-rate that aims to provide cryptographic keys for security. The link between the two devices is maintained by the security orotocol of the ZigBee. There are various physical attacks on the ZigBee radio regarding the frequency breach (Osseiran et al., 2014). The data packets collected during the wireless communication ca be breached. Shaikh, Faisal Karim, and Sherali Zeadally. "Energy harvesting in wireless sensor networks: A comprehensive review." Renewable and Sustainable Energy Reviews 55 (2016): 1041-1054. This paper deals with the harvesting of energy in the Wireless Sensor Network (WSN). WSN consist of large number of static sensor nodes that helps in low processing. There are various sources of energy for the WSNs including Radio Frequency-based energy harvesting, Solar-based energy harvesting, Thermal-based Energy Harvesting and Flow-based energy harvesting. There are various approaches discussed in the paper for the energy harvesting. As argued by (), the energy harvesting system might cause damage to the ecological balance of the nature. The harvesting from different sources causes depletion of the resources in the environment. Choochaisri, Apicharttrisorn Intanagonwiwat, (2017) argued that log lasting devices consumes more battery and causes energy draining. The energy-efficient reliable systems provides benefit to the users in the form of ultra-energy efficient sensors. Ulukus, Sennur, et al. "Energy harvesting wireless communications: A review of recent advances." IEEE Journal on Selected Areas in Communications 33.3 (2015): 360-381. This paper discusses about the new technologies implemented in the energy-harvesting sector. As commented by Fontes et al., (2017), the new advances in the energy harvesting have changed the traditional scenario of energy harvesting. There are various potential model used in recent market for energy harvesting. On the other hand, Choochaisri, Apicharttrisorn Intanagonwiwat, (2017) argued that the use of the modern techniques in the energy harvesting have increases the initial cost of various energy sources and also depleting the natural resources. Various equations and theories discussed in the paper that utilizes the traditional concept of energy harvesting and converting it into modern technology (Osseiran et al., 2014). The possible improvement in the traditional theory has been upgraded into modern tactics. The VLSI model is used for understanding the complexity and energy of decoding and encoding in system.
