Computer chips and storage elements are expected to function as quickly as possible and be energy-saving at the same time. Innovative spintronic modules are at an advantage here thanks to their high ... Researchers aim to streamline the time- and resource-intensive process of screening ligands during catalyst design by using virtual ...

Franklin Releases Apple Ii clones

In this course, we use Microsoft's Excel spreadsheet application software. Everything you do on your computer will rely on both hardware and software. For example, right now you may be viewing this lesson in a web browser and using your mouse to click from page to page. As you learn about different types of computers, ask yourself about the differences in their hardware.

View our project gallery — play some of the games or try out some of the apps that students have created. You can “remix” the project to make it your own, or build something new in App Lab, Game Lab, or Web Lab. In this series of eight short videos, you’ll learn how the internet was invented, what HTML is, and how search engines like Google work.

Officially known as the Track Write, the automatically expanding full-sized keyboard used by the ThinkPad 701 is designed by inventor John Karidis. The keyboard was comprised of three roughly triangular interlocking pieces, which formed a full-sized keyboard when the laptop was opened -- resulting in a keyboard significantly wider than the case. This keyboard design was dubbed “the Butterfly.” The need for such a design was lessened as laptop screens grew wider. Xerox PARC physicist Gary Starkweather realizes in 1967 that exposing a copy machine’s light-sensitive drum to a paper original isn’t the only way to create an image. So in 1971, Starkweather transferred to Xerox Palo Alto Research Center , away from corporate oversight. Within a year, he had built the world’s first laser printer, launching a new era in computer printing, generating billions of dollars in revenue for Xerox.

The J-Phone line would quickly expand, releasing a flip-phone version just a month later. Cameras would become a significant part of most phones within a year, and several countries have even passed laws regulating their use. Dubbed a “Personal Data Assistant” by Apple President John Scully in 1992, the Newton featured many of the features that would define handheld computers in the following decades. The handwriting recognition software was much maligned for inaccuracy.

The 1401 mainframe, the first in the series, replaces earlier vacuum tube technology with smaller, more reliable transistors. Demand called for more than 12,000 of the 1401 computers, and the machine´s success made a strong case for using general-purpose computers rather than specialized systems. By the mid-1960s, nearly half of all computers in the world were IBM 1401s. The TX-0 (“Transistor eXperimental - 0”) is the first general-purpose programmable computer built with transistors.

More than one hundred Paragons were installed over the lifetime of the system, each costing as much as five million dollars. The Paragon at Caltech was named the fastest supercomputer in the world in 1992. Paragon systems were used in many scientific areas, including atmospheric and oceanic flow studies, and energy research. It would serve as the model for several other significant multi-processor systems that would be among the fastest in the world.

Intel's Touchstone Delta Supercomputer System Comes Online

The DN100 is based on the Motorola microprocessor, high-resolution display and built-in networking - the three basic features of all workstations. Apollo and its main competitor, Sun Microsystems, optimized their machines to run the computer-intensive graphics programs common in engineering and scientific applications. Apollo was a leading innovator in the workstation field for more than a decade, and was acquired by Hewlett-Packard in 1989.

The autonomy of the individual systems and the fact that these systems were connected by wide-area networks with latency higher than the latency of the interconnection network of a supercomputer posed serious challenges to this vision. Nevertheless, several “Grand Challenge” problems, such as protein folding, financial modeling, earthquake simulation, and climate/weather modeling, run successfully on specialized grids. 8 compulsory modules at level 5, covering programming skills needed for software projects and specialist topics such as Graphics Programming and Data Science. As you represent a broad role in IT, your job will be similar to that of systems analysts, systems designers and applications programmers, whose roles are more specialized but nonetheless work on a consultancy basis.

unplugged Activities: Computer Science Without The Computer

Such material can be letters, numbers, or facts like grades in a class, baseball batting averages, or light and dark areas in a photograph. Processed data becomes information, data that is organized, meaningful, and useful. In school, for instance, an instructor could enter various student grades , which can be processed to produce final grades and perhaps a class average . Data that is perhaps uninteresting on its own may become very interesting once it is converted to information. This architecture was first developed in the 1980s by Acorn Computer Group, which spun off Advanced RISC Machines Ltd., now known as ARM.
