what does it mean to apply information technology appropiately?

Answer
Information technology is pretty much anything having to do with computers, databases, and the Internet.

If you're applying information technology appropriately, it means you're doing your homework in terms of buying computers, software packages, network systems, database management software and hardware, and Internet access -- you don't want to buy too many computers, or spend extra money on computer features you don't need (why get high-end graphics cards in your computers if they're being used for your garden-variety business), and you don't want to invest in software packages you don't need either. For networks, you need a network system that isn't too big but isn't too small either -- and you may want to think about company growth when you set up your network.

Applying information technology appropriately also means you're using the tools at your disposal as effectively as possible to help run your business. This may involve training people on how to use certain programs/applications, or even developing your own software/systems to do whatever you need to do.

Wht is HT technology?

what is htt technology in intel p4

Answer
HT technology stands for Hyper Threading technology. The advantages of Hyper-Threading are listed as: improved support for multi-threaded code, allowing multiple threads to run simultaneously, improved reaction and response time, and increased number of users a server can support.

According to Intel, the first implementation only used an additional 5% of the die area over the "normal" processor, yet yielded performance improvements of 15–30%.

Intel claims up to a 30% speed improvement compared against an otherwise identical, non-SMT Pentium 4. The performance improvement seen is very application-dependent, however, and some programs actually slow down slightly when HTT is turned on. This is due to the replay system of the Pentium 4 tying up valuable execution resources, thereby starving the other thread. However, any performance degradation is unique to the Pentium 4 (due to various architectural nuances), and is not characteristic of simultaneous multithreading in general.

Hyperthreading allows the operating system to see two logical processors rather than the one physical processor present

Hyper-Threading works by duplicating certain sections of the processor—those that store the architectural state—but not duplicating the main execution resources. This allows a Hyper-Threading equipped processor to pretend to be two "logical" processors to the host operating system, allowing the operating system to schedule two threads or processes simultaneously. Where execution resources in a non-Hyper-Threading capable processor are not used by the current task, and especially when the processor is stalled, a Hyper-Threading equipped processor may use those execution resources to execute the other scheduled task. (The processor may stall due to a cache miss, branch misprediction, or data dependency.)

Except for its performance implications, this innovation is transparent to operating systems and programs. All that is required to take advantage of Hyper-Threading is symmetric multiprocessing (SMP) support in the operating system, as the logical processors appear as standard separate processors.

However, it is possible to optimize operating system behaviour on Hyper-Threading capable systems, such as the Linux techniques discussed in Kernel Traffic. For example, consider an SMP system with two physical processors that are both Hyper-Threaded (for a total of four logical processors). If the operating system's process scheduler is unaware of Hyper-Threading, it would treat all four processors the same. As a result, if only two processes are eligible to run, it might choose to schedule those processes on the two logical processors that happen to belong to one of the physical processors. Thus, one CPU would be extremely busy while the other CPU would be completely idle, leading to poor overall performance. This problem can be avoided by improving the scheduler to treat logical processors differently from physical processors; in a sense, this is a limited form of the scheduler changes that are required for NUMA systems.

I am applying for Tennessee Governor's School for Informational Technology Leadership. I am more interested in the Business Leadership aspect, but for my application it is asking ways information technology has helped businesses operate more effectively and asks to give concrete examples.

If you could please give me a summary of what Information technology is, and some examples of the way it has helped I will derive my own answers.

Thanks in advance.

Answer
Information technology, as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." Encompassing the computer and information systems industries, information technology is the capability to electronically input, process, store, output, transmit, and receive data and information, including text, graphics, sound, and video, as well as the ability to control machines of all kinds electronically.

Information technology is comprised of computers, networks, satellite communications, robotics, videotext, cable television, electronic mail ("e-mail"), electronic games, and automated office equipment. The information industry consists of all computer, communications, and electronics-related organizations, including hardware, software, and services. Completing tasks using information technology results in rapid processing and information mobility, as well as improved reliability and integrity of processed information.

Answer
Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit and retrieve information, securely.

Recently it has become popular[citation needed] to broaden the term to explicitly include the field of electronic communication so that people tend to use the abbreviation ICT (Information and Communications Technology), it is common for this to be referred to as IT & T in the Australasia region, standing for Information Technology and Telecommunications.

Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term is more recognizable than ever before. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.
