...special features, which is why it should eventually occupy the place of the VCR in American households. Introduction I’d like to start things out by taking a survey. How many of you remember having a CD player in your house fifteen years ago? Not very many of you, I see. Of course, we all have CD players now. It took a little over a decade and some major price drops, but eventually we all threw out our old vinyl and cassettes and opted for the excellent sound quality and convenience of CDs. Just as the CD took the place of cassettes, many people believe the DVD, or digital versatile disc, will soon take the place of VHS tapes. Many of you may not even know what a DVD is, so before I go any further, let me show you what one looks like. (Take out DVD disc) It’s the same size as a CD, but it has two sides. Just like a VHS tape, it plays movies directly on your television. DVD video players were originally released in early 1997, and their first year sales were twice that of CD players, which is strong evidence that the DVD is here to stay. Why is the DVD so popular, and what makes it better than VHS? There are three main reasons: sound quality, picture quality, and special features exclusive to DVD. (Transition: Let’s start with the sound quality of DVD) Body I. The sound quality of DVD is far superior than that of VHS. A. DVD discs utilize digital technology, which is the same technology used by compact discs. 1. This means that you will...

FKT can read AccessData, Expert Witness, SafeBack, SMART and raw format files, CD and DVD files. Proprietary format tools run an option to compress or not compress image files of a source drive, to save space on the target drive. Hashing helps check the integrity of the data. Various tools can integrate metadata into the image file But there exits an inability to share an image between different vendors’ computer forensics analysis tools. Like ILook imaging tool IXimager produces IDIF, IRBF, and IEIF but can be read only by ILook. Proprietary format tools produce a segmented file of 650 MB. Maximum file size per segment can be 2 GB. 2. Disk-to-disk copy: UNIX/Linux dd command does disk-to-disk copy. dd command is very easy and effective in a Linux machine. But for that we need equal or larger space in the target disk to copy full image from the source disk. Raw formatting is a technique in which we use dd command to generate image files which are split into smaller segments and are exact bit-by-bit replica of the original disk. These are sequential flat files of the source drive. Hardware and software duplicators are available for disk to disk copy. Hard duplicators like Logicube Talon,etc and software duplicators like SafeBack, EnCase, etc. Raw format is faster data transfers and has the ability...

It is not a comprehensive list but we have prioritised resources that are up-to-date and available. The resources have been listed under four categories; primary level, secondary level, special needs/disabilities and resources for parents & carers. Resources falling into more than one category are listed in all relevant lists. A suggested age-range is given for each resource; however the maturity of children and young people varies so this should be used as a guide only. The Sex Education Forum advises professionals to make their own choices about which resources to use. We do not endorse the resources on this list. The questions in the box below can help to choose and use a resource that will contribute to good quality sex and relationships education. Choosing a resource Is the resource consistent with the values set out in the school or college SRE policy? Is it factually correct and up-to-date? Does it encourage active and participatory learning? Is the resource contemporary in terms of the realities of young people’s lives? Does the resource portray positive images of a range of young people? Does the resource show positive role models for young men and young women – and avoid stereotypes relating to gender and sexual orientation?

...the computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting of input from human operators and the output of results formatted for human consumption. The interface between the computer and the human operator is known as the user interface. A computer is like a brain which can think, calculate, retrieve and organize information for its human master. This brain is supplied with parts that provide allow for input to it and allow it produce output for presentation to the one using it. Central Processing Unit The thinking part of the brain of the computer is the CPU or Central Processing Unit. This component provides all the control and manages calculations and manipulation of data. Computer manufacturers are always trying to squeeze more speed and multiprocessing capability (doing multiple things at the same time) out of it. This has led to the dual core or multiple core CPU which is popular today. A core is basically a computer so that a dual core computer is really 2 computers in one. Computer speed is usually measured in GHz which means Gigahertz which in turn mean billions of cycles per second. The basic idea is that the higher the number of cycles, the faster the computer is. Today the computer manufacturers are depending on the combined power of multiple cores to provide the power instead of the number of GHz. Memory The CPU has no memory.

What is commonly referred to as "MPEG video" actually consists at the present time of two finalized standards, MPEG-1 and MPEG-2, with a third standard, MPEG-4, in the process of being finalized . The MPEG-1 & -2 standards are similar in basic concepts. They both are based on motion compensated block-based transform coding techniques, while MPEG-4 deviates from these more traditional approaches in its usage of software image construct descriptors, for target bit-rates in the very low range, < 64Kb/sec. Because MPEG-1 & -2 are finalized standards and are both presently being utilized in a large number of applications, this case study concentrates on compression techniques relating only to these two standards. MPEG 3- it was originally anticipated that this standard would refer to HDTV applications, but it was found that minor extensions to the MPEG-2 standard would suffice for this higher bit-rate, higher resolution application, so work on a separate MPEG-3 standard was abandoned.

Referencing - the Harvard System

...Referencing - The Harvard System Introduction As a student, it is important that you identify in your assessment when you are using the words or ideas of another author.  The most accepted way of acknowledging the work of another author is to use a referencing system.  Within the Business School you are required to use the Harvard referencing system. This guide therefore describes the Harvard referencing style, which uses an ‘alphabetical-by-author’ approach. What is referencing? It is a method used to demonstrate to your readers that you have conducted a thorough and appropriate literature search, and carried out appropriate reading. Equally, referencing is an acknowledgement that you have used the ideas and written material belonging to other authors in your own work. There are many styles that can be used to reference. Why you should use a referencing system As a part of an academic community, it is important that you show the reader where you have used someone else’s ideas or words.  Failure to properly reference using the Harvard system may make the reader think that you are cheating by claiming someone else’s work as your own.  In the academic environment, we call this plagiarism and it is seen as a very serious offence.  Please remember that plagiarism is not just when you directly copy words from another student’s or expert’s work.  Plagiarism also occurs when you re-word someone else’s ideas in your own work and you do not give credit to the original source...

Hardware

...HARDWARE Introduction The term computer hardware refers to the physical parts of a computer which by interconnection and synchronization make up the computer system. The hardware can be divided in two groups: parts that are found in the central unit – housing of the computer called components and external parts called peripheral units. There is a range of computer components, but we will mention the most important, explaining their function and role in the computer. We can point out the following basic elements of computer system: * Motherboard (mainboard) * Processor (CPU - central processing unit) * Memory (RAM - random acces memory) * Graphic Card * Audio Card (Sound card) * Hard Drive (HDD - hard disc drive) * CD-DVD ROM (Compact disc / Digital video drive-Read only memory) * Network card (LAN Adapter - locall area network adapter) * Modem (modulator-demodulator) * Power Supply (PSU - power supply unit) * Input-Output units (I / O) Each of the following elements have distinct and essential function and role in contributing to the work of the computer, depending on the quality and performance, hardware directly affects system performance. Preserving the compatibility of components is equally important as selecting the brand and quality. Each motherboard is not compatible with any graphics card, processor or memory, because there are different standards that are mostly defined by the manufacturer or are dictated by the...

Video Compression: an Examination of the Concepts, Standards, Benefits, and Economics

... ITEC620 April 14, 2008 To accommodate the increased demand for digital video content, compression technology must be used. This paper examines the most commonly used compression formats, the MPEG-1, MPEG-2 and MPEG-4 video compression formats, their relative benefits and differences, the delivery methods available for digital video content and the economics of video content delivery. Every time a digital video disc is played, a video is watched on YouTube, an NFL clip is viewed on a Sprint-based cellular phone, or a movie is ordered through an on-demand cable television video service, the viewer is watching data that is not in the state it which it originated. Video in an unmodified state is comprised of vast quantities of data (Apostopoulos & Wee, 2000). In order to make effective and efficient usage of video data, some method of reducing the quantity of data is necessary. Apostopoulos and Wee, in their 2000 paper, “Video Compression Standards” explain this succinctly and well, “For example, consider the problem of video transmission within high-definition television (HDTV). A popular HDTV video format is progressively scanned 720x1280 pixels/frame, 60 frames/s video signal, with 24-bits/pixel (8 bits for red, green, and blue), which corresponds to a raw data rate of about 1.3 Gbits/sec. Modern digital communication systems can only transmit approximately 20 Mb/s in the 6MHz bandwidth allocated for each terrestrial (over-the-air)...
