Building Information Systems

Overview

System Construction Process

1).Identify a large IT problem to solve


2).Break the large problem into several smaller, more manageable piece.


3).Translate each piece (small problem) into computer programs


4).Piece together each program into an overall comprehensive IS that solves the problem ....etc

Quantum Information Technology

The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics. This document aims to summarize not just quantum computing, but the whole subject of quantum information theory. It turns out that information theory and quantum mechanics fit together very well. In order to explain their relationship, the paper begins with an introduction to classical information theory .The principles of quantum mechanics ....etc

The World Wide Web has become an invaluable information resource but the explosion of information available via the web has made web search a time consuming and complex process. Index-based search engines, such as AltaVista, Google or Infoseek help, but they are not enough. This paper describes the rationale, architecture, and implementation of a next generation information gathering system “ a system that integrates several areas of Artificial Intelligence (AI) research under a single umbrella. Our solution to the information explosion i ....etc

Embedded system is a combination of computer hardware, software and, perhaps, additional mechanical parts, designed to perform a specific function.

Embedded systems are usually programmed in high level language that is compiled (and/or assembled) into an executable (machine) code. These are loaded into Read Only Memory (ROM) and called firmware, microcode or a microkernel. The microprocessor is 8-bit or 16-bit.The bit size refers to the amount of memory accessed by the processor. There is usually no operating system and ....etc

Steganography ,from the Greek, means covered or secret writing, and is a long-practiced form of hiding information. Although related to cryptography, they are not the same. Steganography's intent is to hide the existence of the message, while cryptography scrambles a message so that it cannot be understood.

Steganography includes a vast array of techniques for hiding messages in a variety of media. Among these methods are invisible inks, microdots, digital signatures, covert channels and spread-spectrum communications. Today, thanks to moder ....etc
