...Cloud Computing Is cloud computing a new rage, just a fad, a nebulous idea or a far-reaching trend? Cloud computing has become a buzz word in working and learning environments around the globe. Newsstands and Internet pages everywhere are inundated with articles, whitepapers and websites dedicated to defining the many facets of cloud computing such as hosting a website on the cloud, building a cloud infrastructure, cloud security, vulnerabilities, capabilities, pros and cons and cost. IEEE.org (IEEE CLOUD COMPUTING) has dedicated pages on their website to reference nothing but articles of interest and white papers surrounding cloud computing. The barrage of information can be daunting. Jon Oltsik (Oltsik) eloquently discusses industries’ bewilderment with cloud computing when he writes: When discussing cloud computing, I often think of Joni Mitchell's haunting lyrics from the song,Both Sides Now (jonimitchell.com). In Mitchell's world, clouds can be wonderful "ice cream castles in the air" or annoying disturbances that "only block the sun." This duality prompts Mitchell to declare, "It's clouds illusions I recall, I really don't know clouds at all." Joni's cloud confusion mirrors current industry bewilderment over cloud computing. Like many other industry initiatives, cloud computing has a number of meanings. Finally, industry confusion is no more. A guideline has been prepared by the National Institute of Standards and Technology (NIST). NIST is responsible...

...its “natural advantages” and promise that one day a mighty settlement will rise there. Speculative development is proceeding rapidly and unevenly. But right now the settlers seem a little eccentric and the humble structures they have erected lack the scale and elegance of those in better developed regions. Development is uneven and streets fail to connect. The native inhabitants have their ideas about how things should be done, which sometimes causes friction with new arrivals. In a generation everything will be quite unrecognizable, but how? This is a guide to the growing (if ramshackle) secondary literature in the history of information technology: monographs, edited volumes, and journal articles written to explore different aspects of computing from historical perspectives. Except as a frame in which to situate these secondary...

For other uses, see Computer system (disambiguation). "Computer technology" redirects here. For the company, see Computer Technology Limited. Computer | | A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved. The first electronic digital computers were developed between 1940 and 1945 in the United Kingdom and United States. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] In this era mechanical analog computers were used for military applications. Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple...

...how software and hardware interact to create a network or platform. In other words computer architecture is the design of the network base on the needs of the user, the system if it is there or needs to be built, and the technology that needs to go into the project. System design is all how all the hardware is set up while the instruction set architecture is the program language. Table of Contents Introduction What OS file system should we use? What types of processors? Cluster Architecture? Data Backup LAN or WAN Web-based diagram Introduction to Coast to Coast computing We can get in a plane and be across the country in a few hours but what if we need to work together faster than a few hours? Is it possible? How hard is it to have users in California work with users in Washington, New York, and Florida? What has to be done to make this happen? How secure will it be to have such a network? This and many other questions come up when a company starts thinking of expansion beyond the building or city they headquartered at. When looking at a network a business wants to be sure it is using the most cost effective form for the network. The base of a network is the architecture. For small businesses a peer to peer architecture would be best. There are three types of peer-to-peer architecture: collaborative computing, instant messaging, and affinity communities. In collaborative computing the unused CPU processing power along with any free disk space is combined with...

...storing, and communicating information, including all types of computer and communications systems as well as reprographics methodologies. It refers to anything related to computing technology, such as networking, hardware, software, the Internet, or the people that work with these technologies. Many companies now have IT departments for managing the computers, networks, and other technical areas of their businesses. IT jobs include computer programming, network administration, computer engineering, Web development, technical support, and many other related occupations. Since we live in the "information age," information technology has become a part of our everyday lives. That means the term "IT," already highly overused, is here to stay. The role of information technology systems in a business environment can be classified into four broad categories. These categories include function performance, communication through networking, management and enterprise roles. Information technology provides commercial and industrial systems for businesses. These systems enable businesses to function effectively and efficiently. Function IT Systems Function IT systems are applications that allow individuals to function effectively in the workplace. Examples of common IT systems that enhance workplace functions are word processor applications, spreadsheet applications, statistical analysis software and computer aided design (CAD) programs.

It's a nothing that feels like something, perhaps a black hole, perhaps a lonely place. They have words for it, perhaps "void", "emptiness", "nothingness". Nothingness is not nothing. It comes and it goes, so it's got to be something. You can look at it. You can hold it. You can throw it out. And when you throw it out, what's left?... ...And that's all we're going to say about that. This little introduction has nothing to do with the articles on the site.

...From the earliest times the need to carry out calculations has been developing. The first steps in involving the development of counting and calculation aids such as the counting board and the abacus. The word ‘computer’ is an old word that has changed its meaning several times last few centuries. Originating from the Latin by the mid-17th century it meant ‘someone who computes’. The American heritage dictionary (1980) gives its first computer definition as ‘a person who computes’ meaning to calculate. Today, the word computer refers to computing devices that can store, retrieve and process data. The term ‘computer’ is derived from Latin word “computer” meaning to calculate. In the past computer is restricted only to arithmetic calculation. In the past time the weight of the computer is very heavy and also has large surface area. It can moved from one place to another place. It is as big as one class room. It also cannot be operated with one or even with few persons. It has own staff members for only one computer to be operated. The first compute is shown in below...

...------------------------------------------------- ICT * * * * Stands for "Information and Communication Technologies." ICT refers to technologies that provide access to information through telecommunications. It is similar to Information Technology (IT), but focuses primarily on communication technologies. This includes the Internet, wireless networks, cell phones, and other communication mediums. In the past few decades, information and communication technologies have provided society with a vast array of new communication capabilities. For example, people can communicate in real-timewith others in different countries using technologies such as instant messaging, voice over IP (VoIP), and video-conferencing. Social networking websites like Facebook allow users from all over the world to remain in contact and communicate on a regular basis. Modern information and communication technologies have created a "global village," in which people can communicate with others across the world as if they were living next door. For this reason, ICT is often studied in the context of how modern communication technologies affect society.

...Why the fifth point, “Meet information requirements of management”, is in the CIO’s list “Society is bombarded with data”( Scams & Fraud, 2012). Often so much information is received and as a result we feel overloaded! There's e-mail, web processing, instant messaging, voice mails, and a myriad of other means of communication that are constantly streamed to us daily. Dealing with the organization and management of information can be frustrating and make us want to pull our hair out, but nonetheless, it must be given serious attention. Businesses are driven by data, and the information derived from data is an extremely valuable asset in today's environment and most organizations are dependent on its availability and accuracy. The electronic age has brought new challenges in managing information that previously was non-existent prior to computers and the Internet. While technology has generated higher efficiency, access, and integrity with the newer ways to organize and manage information, it can be overwhelming. Managing data information has become a job in itself, yet it is an important one. In today's global economy, networks have created ways to rapidly transmit data. As a result managers must be able to obtain current data quickly in order to make informed and up to date decisions. This requires readily accessible information at their fingertips in order to analyze. Instantaneous recall information is often crucial, and in order to achieve this, efficient file management...

...History of Computer “Computer” is probably one of the most heard words nowadays. When we hear this word, we can picture a monitor with a rectangular box, keyboard and a mouse in technical sense. But literally what is computer? A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved. But the computer that we are used to seeing now is not a result of one day. It’s a result of many years. Many scholars have shared their idea to develop this device, though Charles Babbage is called the main person behind the invention of computer. A brief history of computer is provided below: I would divide the history behind computer into two parts. First one is history before birth of Jesus and second one is history after birth of Jesus. History before birth of Jesus: Actually there are not many events in this period that contribute to today’s computers but this period has...

...The computer is the most wonderful gift of science to the modern man. The computer can do all the works of man. Thus, after the invention of computer, the gap between man and machine has been bridged up. The dictionary meaning of the word "Computer" is an electronic calculating machine. It is derived from the word compute which means to reckon. But the function of the computer has expanded beyond the act of reckoning. Though a machine, it contains and provides innumerable information's and artificial intelligence of a very high order. It may seem strange, but it is true that the memory and intelligence of a computer can surpass those of a living human being. The mechanism of the computer is very simple. Information processing is the essence of computing. It is a data based machine. The data is fed into the machine. The machine is manipulated and then the due information is retrieved. Computer was invented due to the pressures of World War-II which witnessed the use of such sophisticated weapons as night bombers, submarines, and long range guns on ships and tanks, etc. The defenders have to fight back by shooting at targets and those targets of the enemy can be located by radar. Radar can inform not only about the location of the enemy but also about the direction and the speed of the enemy weapons. Detailed mathematical calculations are necessary to find out these things accurately. Firing tables are required by the front line soldiers. Thus the necessity of calculations...

This is used to provide the equivalent grades of a student. Producing their grade in a shorter time is the top purpose why it’s been develop. This is used to compute the performance of a student, have his/her exact grade within the subject and for the whole grading. Computerized grading system is used to eliminate the word “manual” in our generation. As I study the system of St Cyr Academy, I noticed that they still using manual computations of grades, a calculator to total each student’s grade. Have a slow process of retrieving and releasing of records. On what we have today, many had changed so whatever changes environment brings we should have to mingle into it. Don’t stick to what we usually do, try other things which will make the work much better. In connection to this, I decided to design a computerized grading system for them to align in the modification of the changing environment. Make their work in a fast and easier way. Minimize the effort they exerted and have the desired output they want in a shorter time. Lastly, storing and accessing old data can be done. ...

Dugan IT101-AT6 Ethical issues in Information Technology Information Technology And Resource Use As of Autumn 2003, leadership of the Network for E (N4E) is being taken over by Professor Scott Matthews of Carnegie Mellon, one of its founding members. Jon Koomey began a leave of absence from LBNL beginning in August 2003 (his LBL email and phone will still reach him while he's on leave). Koomey et al., "Sorry, wrong number: The use and misuse of numerical facts in analysis and media reporting of energy issues.", which contains the most complete summary of the controversy over electricity used by office equipment, was published in the 2002 issue of Annual Review of Energy and Environment (also LBNL-50499). vol. 27,. pp. 119-158. Email JGKoomey@lbl.gov for a copy. Baer et al. "Electricity requirements for a digital society" was published at the end of 2002 RAND Corporation, MR-1617-DOE, ISBN 0-8330-3279-8. They concluded that projections of information technology totalling 50% of electricity use in twenty years are completely implausible. Instead, their scenarios project something under five percent for office and communications equipment in all cases by 2020.
