...Portable Computing Devices Jason Coltrain ITT Technical Institute NT 1110 SAT AM Research Project Portable Computing Devices What is Portable Computing? The answer to that question is bigger than most people think. Mobile/Portable computing is defined as the ability to use technology that is not physically connected to any static network. This actually used to mean radio transmitters that operated on a stable base, usually with the help of large antennas. 2 way radios used by police officers were also considered mobile technology but now, it means people can connect wirelessly to the internet or to a private network almost anywhere. As long as a person has one of the devices capable of wirelessly accessing the internet, they are participating in mobile computing. What are portable computing devices? It could be a Tablet, which is a one-piece mobile computer. Devices typically have a touchscreen, with finger or stylus gestures replacing the conventional computer mouse. It is often supplemented by physical buttons or input from sensors such as accelerometers. An on-screen, virtual keyboard is usually used for typing. Mobile phones also known as smartphones are also portable computing devices. A mobile phone or smart phone is a mobile phone, small enough to fit in your hand and in your pocket, built on a mobile operating system, with more advanced computing capability. Portable computing devices are increasingly powerful and affordable. Their small size and functionality...

...The History of Computers http://inventors.about.com/library/blcoindex.htm "Who invented the computer?" is not a question with a simple answer. The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention. This series covers many of the major milestones in computer history (but not all of them) with a concentration on the history of personal home computers.

...Input Devices Input devices – is devices that we put INTO the computer from the real world to receive data or information. ID can be as human interaction as keyboard and mouse or simply environmental data as sensors. This is the list of possible examples of input devices such as : Camera , Compact Disk, Keyboard , Mouse , Digital Camera, Microphone , Drawing Tablet , Scanner, Disk Drive , Joystick , Touch Screen, Barcode reader , Business Card reader , Magnetic-stripe reader, etc. First of all, an input device is any hardware device that sends data to the computer, without any input devices. In other words the input unit is formed by the input devices attached to the computer. An input unit takes the input and converts it into binary form so that it can be understood by the computer. Camera is used during live conversations. The camera transmits a picture from one computer to another, or can be used to record a short video. Compact Disk (CD) - The CD can be put into another computer, and the information can be opened and added or used on the second computer. There is one possible thing like a CD-R or CD-RW can be used as an output device. Keyboard is a way to input letters or numbers into different programs or web-bourses. A keyboard also has special keys that help operate the computer. For ex. key “Microsoft” that helps us to open “start” section whenever we need. Mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the...

...The History of Information Technology March 2010 Draft version to appear in the Annual Review of Information Science and Technology, Vol. 45, 2011 Thomas Haigh thaigh@computer.org University of Wisconsin, Milwaukee Thomas Haigh The History of Information Technology – ARIST Draft 2 In many scholarly fields the new entrant must work carefully to discover a gap in the existing literature. When writing a doctoral dissertation on the novels of Nabokov or the plays of Sophocles, clearing intellectual space for new construction can be as difficult as finding space to erect a new building in central London. A search ensues for an untapped archive, an unrecognized nuance, or a theoretical framework able to demolish a sufficiently large body of existing work. The history of information technology is not such a field. From the viewpoint of historians it is more like Chicago in the mid-nineteenth century (Cronon, 1991). Building space is plentiful. Natural resources are plentiful. Capital, infrastructure, and manpower are not. Boosters argue for 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...

...From the Abacus to the PC: A Selective History of the Computer Thousands of years ago, the abacus was invented; it was this seemingly simple device that aided a human with calculations, which would be used as the conceptual model to build the computer. Looking back, one of the earliest instances of computer technology in action was not found in a computer at all but in a loom. The Jacquard loom, patented in 1804, was programmed by punched cards to create patterns in woven cloth (Keats 72). Charles Babbage, the English mathematician and many others would eventually use punch cards to program the computers they developed. The computer has taken many forms through the ages, and it would not be until almost 100 years later that the first fully electronic computer, the Atanasoff Berry Computer (ABC), would be developed, ushering in the age of electronic computing. The earliest computing device known, the abacus, a tool for counting and calculating, was invented thousands of years ago, and it consisted of beads on a frame whose numerical value was indicated by their position on the frame (Fernandes). In addition to being beads on a frame, an abacus was a stone or an area on the ground with grooves in which pebbles were placed and then manipulated for calculating. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used (“Abacus”). The abacus used the biquinary numbering system, a numbering system used in some early computers...

...Emerging Cloud-Computing Industry Case Study Analysis Introduction The character of a company -- the stamp it puts on its products, services and the marketplace -is shaped and defined over time. It evolves. It deepens. It is expressed in an ever-changing corporate culture, in transformational strategies, and in new and compelling offerings for customers. Those are the words that start the chronological history on the IBM website [1]. I couldn’t agree anymore with that statement. I am often very fascinated by the evolvement of technology stories I get to hear quiet often from my fellow senior coworkers. One of the stories I enjoy is about the large IBM370 computer my workplace once owned in 1970’s. From my understanding it occupied a whole room and it required several people to operate. That was less than a half century ago. Today the smart phone’s memory is much higher than that computer. For my time what I could relate to, is the floppy disk which of course is obsolete today. I am sure my kids will be fascinated by the floppy disk someday just like I get fascinated by circular slide rule that predated the calculator era. In place of floppy disks or another external memory, in the cyber world today, cloud computing is taking place of all those external memories. IBM website defines Cloud computing as, the delivery of on-demand computing resources everything from applications to data centers over the Internet on a pay-for-use basis [1].

...History and Development of the Digital Computer Prior to the advent of digital computing, human clerks who calculated in accordance with effective methods we referred to as “computers.” Human computing has evolved greatly since that time; giving the need for computing and the advancement of technology an entirely new growth opportunity. A digital computer is “a device that processes numerical information; more generally, any device that manipulates symbolic information according to specified computational processes” (Digital Computer). Each computer is programmed with a basic set of instructions that are the identifiers of what capability that system has to perform functions. Computers are devices used to carry out a myriad of logical operations, and most often consist of at least one processing element. A computer most often contains a memory bank for information storage. Though the idea of computing has been around for a long while, it wasn’t until the mid-1900’s that “computers” came alive. The dinosaurs of the mid-1900 were mammoth machines housed in large buildings and warehouses and consumed more energy for one operating system than hundreds of today’s mini machine’s do. Today’s computers are miniscule in size in comparison to that of their ancestors and have the capability of far more computing power. As technology has evolved, the computer has taken the shape of laptops, music players, gaming systems and automobiles; each of these tangible items relies on some sort...

...Cloud Computing Cloud computing is the delivery of computing as a service rather than a product. Resources like software and information are provided to computers and communication devices as a utility like electricity or water. This cloud computing service is done through a computer network, which is the internet typically. Cloud computing is known as encapsulation by some users since the physical location and configuration of how the resources are shared to the devices is often not revealed to the end user. It is like using the electricity. The end user doesn’t have to know the whereabouts of the physical location where the electricity is produced nor how the components are configured from there to their home. They just use the feature or resource instead. Similar to this cloud computing describes the consumption of IT services through the common most computer network available in the world, the internet. Virtualized resources can be shared remotely with ease-of-access exploiting the facilities provided by the internet. The end user must have a tool or an application (Web Browser) installed on their local computers which provides the platform for the sharing of resources. Providers of cloud computing deliver applications or tools via the internet, which are accessed using web browsers and desktop mobile apps, while the main resources (business software and data) are stored in a server located in a remote location. Screen-sharing technology is used sometimes to provide...

...Cloud Computing Reginald L. Butler Dr. Jim Marion CIS 109 September 10, 2013 Cloud Computing History and Origns This quarter at Strayer University I took a course called Intro Management Information Systems online. There were many concepts and technologies we studied, but the one I was most fascinated about was Cloud Computing. Cloud technology has become very popular among consumers over the past decade. The tech is used in a wide variety of electronic devices such as PC’s, smart phones, tablets, streaming devices, etc. Even more important is the impact of cloud computing on the business market. They ways in which a company can use the cloud are limitless if they so choose to invest in the technology. Recently, both Sony and Microsoft stated that cloud technology will play a pivotal role with their next generation consoles coming out this fall. With all the talk of cloud computing going on today one has to wonder how did it become so popular? What are the origins of this new found tech and what will cloud computing evolve to in the future? Cloud computing is a technology that the world is just becoming familiar with, but the tech is not new. According to Wallace (2013), cloud computing was once referred to as “on-demand infrastructure” and has been around since the mid 90’s. Latter in 1995, the on-demand infrastructure was known as “Shared Web Hosting” which features included multi-tenant, automated provisioning, and an easy-to-use interface or (UI) as it’s known...

...Learning Team D: Week 3 Article Analysis "Cloud Computing” Tinesa Robinson, Brian Stanley, Shanelle Chapman, Shameka Neal, Vernae Ellis ECO 561 November 10, 2014 George Sharghi, Instructor The National Institute of Standards and Technologies defines cloud computing as, “ a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” (NIST, n.d). This concept has been around since the 1960’s but it was not until the late 1990’s that this market started to show signs up growth and demand, as significant increases in internet bandwidth availability made this market attractive for consumers and business due to advantages in flexibility, web storage and cost reduction. When a term becomes universal in the consumer market, like cloud is today, that is a sign of an emerging concept. Emerging concepts become a matter of precedence for businesses, as they want to be able to offer this product or service at the beginning of its cyclic climb in the market. It is safe to say that cloud computing caused a paradigm shift from traditional networking and storage to this new virtual interconnectivity framework and with that the jockeying for market has begun. Will this industry turn into a monopoly, oligopoly or a purely competitive market? ...

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...

...vA Very Brief History of Computer Science Written by Jeffrey Shallit for CS 134 at the University of Waterloo in the summer of 1995. This little web page was hastily stitched together in a few days. Perhaps eventually I will get around to doing a really good job. Suggestions are always welcome. A translation of this web page into French has been prepared by Anne Dicky at the University of Bordeaux. Before 1900 People have been using mechanical devices to aid calculation for thousands of years. For example, the abacus probably existed in Babylonia (present-day Iraq) about 3000 B.C.E. The ancient Greeks developed some very sophisticated analog computers. In 1901, an ancient Greek shipwreck was discovered off the island of Antikythera. Inside was a salt-encrusted device (now called the Antikythera mechanism) that consisted of rusted metal gears and pointers. When this c. 80 B.C.E. device was reconstructed, it produced a mechanism for predicting the motions of the stars and planets. (More Antikythera info here.) John Napier (1550-1617), the Scottish inventor of logarithms, invented Napier's rods (sometimes called "Napier's bones") c. 1610 to simplify the task of multiplication. In 1641 the French mathematician and philosopher Blaise Pascal (1623-1662) built a mechanical adding machine. Similar work was done by Gottfried Wilhelm Leibniz (1646-1716). Leibniz also advocated use of the binary system for doing calculations. Recently it was discovered that Wilhelm Schickard (1592-1635)...
