Finally, Sony offers a few exclusive features to its Plus subscribers: They’re able to save game data to a 150GB cloud storage system and set the PS3 to automatically download some system updates and demos as soon as they’re available. Cloud computing is a system in which applications and storage “live” on the Web rather than on a user’s computer. Other application and Web servers (both physical and virtual) provide specific services to the system. Then there’s a software-as-a-service (SaaS) system known as utility computing, in which a company offers specific services (such as data storage or increased processor power) for a metered cost. Control nodes (a node is any device connected to a network that can transmit, receive and reroute data) rely on XML languages like the Web Services Description Language (WSDL). A platform can be an operating system, a computer’s architecture, a computer language or even a Web site. Extensible Markup Language (XML): A computer language that describes other data and is readable by computers.
Without memory, the microprocessor would have to search and retrieve data from a more permanent storage device such as a hard disk drive. Storage: In grid computing terms, storage refers to permanent data storage devices like hard disk drives or databases. Other banks, like Virtual Bank and ING Direct, ask you to choose security questions, such as, “What is your favorite pet’s name?” You provide the answers to these questions. Adventure tour guides lead tourists and adrenaline-seekers on activities like kayaking, white-water rafting, horseback riding, zip lining, scuba diving or snorkeling, fishing and even shark diving. You can also post ongoing status messages, a form of micro-blogging, so that other members can follow your current thoughts or activities. The SETI project created a program called [email protected], which networks computers together to form a virtual supercomputer instead. This is called peer-to-peer sharing, or P2P. The research includes the way proteins take certain shapes, called folds, and how that relates to what proteins do. Life rafts have come a long way in recent years. There are thousands of different ways that motes might be used, and as people get familiar with the concept they come up with even more.
Depending on the software you’ve used, the finished film will be in one of several formats. With the software installed, you’re ready to log on. Keep a written log of decibel readings (there are inexpensive machines that document decibel levels), recordings of the noise and date/time, copies of any written complaints you send to them and so on. The purpose of middleware is to allow different computers to run a process or application across the entire network of machines. Ironically, a hacker could conceivably create a grid computing system for the purpose of cracking encrypted information. An information architect needs a similarly diverse understanding of industry standards for creating, storing, accessing and presenting digital information. Applications based on the same open standards are easier to integrate than ones built on different proprietary standards. It’s hard to protect a system from hackers, particularly if the system relies on open standards. If the system robs users of computing resources, it’s not an efficient system. Other users are still able to access their own machines, but they can’t leverage the entire network. These protocols limit network access to a select number of users. Simple Object Access Protocol (SOAP): A set of rules for exchanging messages written in XML across a network.
That means that two different grid computing systems may not be compatible with one another, because each is working with a unique set of protocols and tools. The Search for Extraterrestrial Intelligence (SETI) project is one of the earliest grid computing systems to gain popular attention. It’s possible to create a grid computing system right now and several already exist. Most computers are upgradeable, which means it’s possible to add more power or capacity to a single computer, but that’s still just an incremental increase in performance. It’s also important that each user connected to the network doesn’t experience a drop in his or her computer’s performance. How do you make sure the user doesn’t tie up all the system’s resources? These computers act both as a point of interface for the user and as the resources the system will tap into for different applications. A grid computing system should tap into unused computer resources without impacting everything else. The potential for grid computing applications is limitless, providing everyone agrees on standardized protocols and tools.
