Computer Technology

The computer technology program transforms students into technology leaders in a sustainable global economy.  This is achieved by presenting students with a strong foundation in the concepts, theories, and practices that serve as the basis for the varying aspects of information technology.  This includes the design, implementation, and adminstration of secured systems and networks.  Students have the opportunity to develope expertise in specialty areas of interest through electives in higher level technology courses.

Since the purpose of information technology is to facilitate the goals and objecties of a business or organization, students are required to complete the Minor in Business Administration.  With an understanding of how organizations operate, students will be able to move effectively design systems and networks that will support the needs of the business or organization.

Exascale Supercomputer

On 29^th July, 2015, President of the United States, Barack Obama, approved the development of an Exascale Super Computer. The Exascale Super computer will be 30 times faster and more powerful than today’s fastest Super Computers. The need to develop such a high performance Supercomputer comes after China’s surge in high performance computing. However, the US still tops the list of Supercomputers with 233 high performance machines. China has 37 Supercomputers but they lead the list of the most powerful and high performance supercomputers since June 2013.

Presently, China’s "Tianhe – 2" is the world’s faster Supercomputer.

The Tianhe – 2 can perform 100 Petaflops, i.e quadrillions of floating point operations per second.

The following table shows list of top five most powerful Supercomputers in the world. you can also view complete list of Top 500 Supercomputers in the world.

Supercomputer

The most powerful computers in terms of performance and data processing are the Supercomputers. These are specialized and task specific computers used by large organizations. These computers are used for research and exploration purposes, like NASA uses supercomputers for launching space shuttles, controlling them and for space exploration purpose.

The supercomputers are very expensive and very large in size. It can be accommodated in large air-conditioned rooms; some super computers can span an entire building.

what is computer

A computer is generally defined as a programmable machine. The two principal characteristics of a computer are: it responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded list of instructions (a program).

what is hardware

• Abbreviated as HW, Hardware is best described as any physical component of a computer system that contains a circuit board, ICs, or other electronics. A perfect example of hardware is the screen on which you are viewing this page. Whether it be a computer monitor, tablet or smartphone; it's hardware.
  Without any hardware, your computer would not exist, and software could not be used. The picture is a Logitech webcam, an example of an external hardware peripheral. This hardware device allows users to take videos or pictures and transmit them over the Internet.
  Below is a list of external hardware and internal hardware that may be found with a computer.

what is software

Software can be thought of as the variable part of a computer and hardware the invariable part. Software is often divided into application software (programs that do work users are directly interested in) and system software (which includes operating systems and any program that supports application software). The term middleware is sometimes used to describe programming that mediates between application and system software or between two different kinds of application software (for example, sending a remote work request from an application in a computer that has one kind of operating system to an application in a computer with a different operating system).

An additional and difficult-to-classify category of software is the utility, which is a small useful program with limited capability. Some utilities come with operating systems. Like applications, utilities tend to be separately installable and capable of being used independently from the rest of the operating system.
