Today the technological advancement has achieved a point that was thought of nothing more than science fantasy a few decades ago. With the emergence of multimedia enable devices users start accumulating large repositories of digital data. Due to the low cost digital storage these archives are progressively being digitalized. These progressions persist at an incredible velocity. These advancements in the information technology have culminated in a collection of immense amounts of information...
It is a hardware device that provides terminals such as PCs and other devices with a main connection of local or wide area network. It connects to the terminal server from their RS-232C or RS-423 serial port. The interface cards connect the outer side of the terminal server to a local area net work by using modems and terminal server does not need his own network interface card or modem. It facilitates the organizations to connect devices with a serial interface to a local area network...
IPSec IP Security provides secure communication over LANS, WANS, and the Internet. IPSec was developed by the IETF Internet Engineering task Force as an extension of IP protocol. The introduction of such Internet Protocol Security addresses several issues which emerged. IPSec mainly have solved 2 problems: host-to-host authentication and encryption. In host-to-host authentication by the overture of IPSec allowed hosts to be able to identify the communicating host and be sure that they are...
First, we must design and develop the website of school. Then we can upload our website to the web hosting company and pay for it. Maybe we can get a fix ip address from ISP and start the web server (for example: Microsoft IIS), after that, we can use own server to operate the website. Therefore, this can be carry out when the project has finished. Can student use the internet to submit their homework? This requirement can carry out easily. We just want to start the ftp server service and set...
Summary This critique will examine the RAF St Athan excavation report by Barber et al. (2006) and asses the aims and purpose of the excavation. It will also consider the arrangement and presentation of both text and illustrations for clarity and reasoning. A general critique of the complete report and the conclusions given will also be commented on. Site and rationale for excavation In the early 2000s the Defence Aviation Repair Agency (DARA), located at RAF St Athan in the Vale of Glamorgan,...
The first types of MS-DOS kept every file in a single directory. This was time-consuming and cumbersome particularly when users added more and more files. To retrieve one file, the file Manager explore from the beginning of the list until more over the file was found on the end of the list was reached. If the user couldn't remember how the file was named the chances are it would never be seen again. Microsoft implemented a hierarchical directory structure in Version 2.0 and inverted tree...
Data mining is what tech industry is getting into. Companies have billions of data points and looking for a means to convert it into revenue. Data mining includes dozens of techniques to collect the information and data and convert it into something from which everyone can benefit. This chapter will introduce you to the report, what all is presented here and what all results were derived. A Network Intrusion Detection System (NIDS) is an intrusion detection system which tries to capture the...

Before discussing wireless networks, it is necessary to take a broad look at networking in general and to see why malicious and selfish behavior is such a relevant issue. For this purpose, we will consider the Internet. The Internet is probably the most impressive achievement ever in networking: A simple set of brilliant engineering rules has led to the deployment of the most pervasive network that, in spite of its size (or rather, thanks to it), supports a growing number of services and...
The goal of this paper is to study the use of mobile devices in health care sector. Mobile technology helps to swiftly access information, help in patient safety, reduce cost and improve workflow to make efficient decisions. Mobile Devices provide remote access, portability, and connectivity which was not available in traditional computers. Mobile devices can be used in various forms like SMS alerts and reminder, use of RFID to decrease medical errors, manage assets and patients, identification...
