Essay on THE NETWORK AS SOMEWHERE ELSE EVERYTHING AS A SERVICE AND THE IDEA OF THE CLOUD

Essay on THE NETWORK AS SOMEWHERE ELSE EVERYTHING AS A SERVICE AND THE IDEA OF THE CLOUD Essay on THE NETWORK AS SOMEWHERE ELSE: EVERYTHING AS A SERVICE AND THE IDEA OF THE CLOUD Essay on THE NETWORK AS SOMEWHERE ELSE: EVERYTHING AS A SERVICE AND THE IDEA OF THE CLOUDThe development of networks technologies have contributed to the consistent changes in the development of network systems. Today, networks are virtually essential for the development of contemporary businesses as well as non-profit organizations. The reason for the emergence of networks in contemporary organizations is the information overflow which forces users to use the network to store and process information which cannot be stored on the conventional hard drives. More important, today, organizations need to share information between all users that makes the development of networks essential because networks allow maintaining the effective communication, data sharing and processing within organizations. In this regard, the development of clouding computing has become one of the recent and mainstream trends that influence the development of the contemporary networking.In fact, the emergence of networking dates back to the early internet era, when users started to use networks to share files and information between each other. However, until the late 1990s, users could store the information they needed on their PCs using conventional hard drives, but since the late 1990s and especially during the 2000s, users have faced the problem of the information overflow, when users had to share a lot of information with many users and they needed to create networks to share information fast between many users.At the dawn of networking, users tended to create conventional peer to peer networks, which normally united several computers, where users could access the information stored on each other’s computer. This was the simplest network that involved sharing data between users. For instance, while working on a project, team members could connect their PCs into the network to get access to information or data generated by each other. However, such a network was oriented on the use by a few users since users should know, where the target information is stored. If there were multiple users, they could have difficulties to find the target information.In such a situation server to client networks emerged to meet the growing demand on networks that would allow users to access the target information any time they needed without facing any difficulties with accessing the target data. The client server network is quite different from peer to peer network because client server network connected users by one server, which users could access to get the information they needed. For instance, a company employing one hundred of employees could use such a network to connect one hundred PCs or laptops of its employees to the server, where the company’s database was available. In such a situation, an employee of the company had just to access the server to find the information he/she needed at the moment. This network system was simple but very efficient because us ers should not store all the information on their hard drives. Instead, they could rely entirely on server. At this point, it is worth mentioning the fact that there was and still is the risk of the server shutdown but such risks can be minimize or its negative effect annihilated, if the company uses redundant drives or backup server which come into play, when the main server shuts down.In fact, today, client server networks become more and more popular due to their high efficiency and relatively low risks associated with using those networks. The major advantage of client server networks is the possibility of sharing information between many users with saving hard drive space of users. At the same time, the primary concern of users, who rely on the clouding technology, is the information security. In fact, the threat of information breaches persists, in spite of the consistent enhancement of information systems. Nevertheless, users have little options to choose from because, in the time of the information overload, they just cannot rely on conventional networks within an organization, such as intranet, instead, they need broader services and opportunities provided by the clouding technology and client server networks.Thus, today, client server networks and cloud technology becomes the mainstream trend that influences consistently the development of the contemporary technology. In fact, the clouding technology boosts the development of the contemporary networking because due to cloud computing, users have got wider opportunities for networking, sharing their information without any substantial limitations on the volume of information.

Ada Lovelace - Mathematics and Computer Pioneer

Ada Lovelace - Mathematics and Computer Pioneer Ada Augusta Byron was the only legitimate child of the Romantic poet, George Gordon, Lord Byron. Her mother was Anne Isabella Milbanke who took the baby at one month old away from her fathers home. Ada Augusta Byron never saw her father again; he died when she was eight. Ada Lovelaces mother, who had studied mathematics herself, decided that her daughter would be spared the fathers eccentricities by studying more logical subjects like math and science, rather than literature or poetry. Young Ada Lovelace showed a genius for math from an early age. Her tutors included William Frend, William King and Mary Somerville. She also learned music, drawing and languages, and became fluent in French. Ada Lovelace met Charles Babbage in 1833, and became interested in a model he had constructed of a mechanical device to compute values of quadratic functions, the Difference Engine. She also studied his ideas on another machine, the Analytical Engine, which would use punched cards to read instructions and data for solving mathematical problems. Babbage also became Lovelaces mentor, and helped Ada Lovelace begin mathematical studies with Augustus de Moyan in 1840 at the University of London. Babbage himself never wrote about his own inventions, but in 1842, an Italian engineer Manabrea (later Italys prime minister) described Babbages Analytical Engine in an article published in French. Augusta Lovelace was asked to translate this article into English for a British scientific journal. She added many notes of her own to the translation, since she was familiar with Babbages work. Her additions showed how Babbages Analytical Engine would work, and gave a set of instructions for using the Engine for calculating Bernoulli numbers. She published the translation and notes under the initials A.A.L, concealing her identity as did many women who published before women were more accepted as intellectual equals. Augusta Ada Byron married a William King (though not the same William King who had been her tutor) in 1835. In 1838 her husband became the first Earl of Lovelace, and Ada became countess of Lovelace. They had three children. Ada Lovelace unknowingly developed an addiction to prescribed drugs including laudanum, opium and morphine, and displayed classic mood swings and withdrawal symptoms. She took up gambling and lost most of her fortune. She was suspected of an affair with a gambling comrade. In 1852, Ada Lovelace died of uterine cancer. She was buried next to her famous father. More than a hundred years after her death, in 1953, Ada Lovelaces notes on Babbages Analytical Engine were republished after having been forgotten. The engine was now recognized as a model for a computer, and Ada Lovelaces notes as a description of a computer and software. In 1980, the U.S. Department of Defense settled on the name Ada for a new standardized computer language, named in honor of Ada Lovelace.
