You can access any data at any location as long as its on a server using the World Wide Web. Thatbenefit highly benefits school systems. There is also the benefit of communication to friends from far away.The biggest disadvantage of World Wide Web is the ever increasing gap between internet haves andhave nots. With the increasing use of WWW in developed countries and among different classeswithin under developed and developing countries, those without access to the internet areconstantly losing opportunities in work related fields.Mobile devices
By Sheilee CherryAn electronic telecommunications device often referred to as a cellular phone or cellphone. Mobilephones connect to a wireless communications network through radio wave or satellitetransmissions. Most mobile phones provide voice communications, Short Message Service(SMS),Multimedia Message Service (MMS), and newer phones may also provide Internet services such asWeb browsing and e-mail.Depending on what type of cell phone, they can do anything from sendinga simple text message to streaming live television. With technology increasing at the rapid rate it hasbeen, newer and newer features are being added to mobile devices.You can carry a mobile phonewith you so you dont miss important calls. If you are lost, you can call for directions. If you are in anaccident, you can call the police or ambulance - and if the phone has a camera, you can take picturesof the accident. You can listen to music, text, and play games when youre bored. Most mobilephones have a calculator and a phone book. You can use a mobile phone to call your customers orboss if you are running late to a meeting. You can surf Internet & Connect with the whole world byMobile. You can chat & video conference. Keep in touch with friends and family. Good foremergencies. Employees can keep in touch at all times. Customers can contact staff 24/7.Phoneshave internet connection. More work available. They have cameras. You can check your emails. Canbe used worldwide. It can fit in your pocket.They can damage your ear. Sometimes the reception ispoor in some areas, limiting your connectivity (you cant talk underground or on planes). People usethe phone while they are driving, and this can cause problems .They can limit your face to face timewith friends and family. They can get you in trouble at school. Can be expensive.Can be hard to findthe right package.Can ruin the connection to the computer. Staff can abuse their phones if they haveinternet connection. Can be hard for older people to use. Because of their smaller size, they can beeasy to lose.Image/Video CaptureImage capture is mostly used digitally now using a mobile phone for instance. Cameras used to be onfilms but now with digital cameras you can take them anywhere they are lighter and have no film soyou can take as many pictures as you need. Another way to capture an image is by using a scanner.These aren’t used as much but if you have an image on a piece of paper you can use the scanner toscan what is on the page and then have it digitally on your computer. It is good for uploading art thatyou have drawn on paper to your computer.
By Sheilee CherryCompressionIs a data encoding method that compresses data by losing some of it? It stores files and combinethem into archives that take up less physical space in memory. When using the lossy technique thefile size will become smaller which is not a bad thing at all, this may be used when uploading animage onto the web, but the image will quality will become worse. The compression techniquemakes the file size smaller than the lossless.Digital file formatsImage file formats are standardized means of organizing and storing digital images. Image files arecomposed of digital data in one of these formats that can be rasterized for use on a computerdisplay or printer. An image file formatmay store data in uncompressed,compressed, or vector formats. Oncerasterized, an image becomes a grid ofpixels, each of which has a number ofbits to designate its color equal to thecolor depth of the device displayingit.The TIFF (Tagged Image File Format)format is a flexible format thatnormally saves 8 bits or 16 bits percolor (red, green, blue) for 24-bit and 48-bit totals, respectively, usually using either the TIFF or TIFfilename extension. TIFFs flexibility can be both an advantage and disadvantage, since a reader that
By Sheilee Cherryreads every type of TIFF file does not exist.TIFFs can be lossy and lossless; some offer relatively goodlossless compression for bi-level (black&white) images.The BMP file format (Windows bitmap) handles graphics files within the Microsoft Windows OS.Typically, BMP files are uncompressed, hence they are large; the advantage is their simplicity andwide acceptance in Windows programs.Streaming methodsStreaming media is multimedia that is constantly received by and presented to an end-user whilebeing delivered by a provider. Its verb form, "to stream", refers to the process of delivering media inthis manner; the term refers to the delivery method of the medium rather than the medium itself.A client media player can begin playing the data (such as a movie) before the entire file has beentransmitted. Distinguishing delivery method from the media distributed applies specifically totelecommunications networks, as most other delivery systems are either inherently streaming (e.g.,radio, television) or inherently nonstreaming (e.g., books, video cassettes, audio CDs). For example,in the 1930s, muzak was among the earliest popularly available streaming media; nowadays Internettelevision is a common form of streamed media. The term "streaming media" can apply to mediaother than video and audio such as live closed captioning, stock ticker, and real-time text, which areall considered "streaming text".Live streaming, delivering live over the Internet, involves a camerafor the media, an encoder to digitize the content, a media publisher, and a content delivery networkto distribute and deliver the content.Data transfer rates
By Sheilee CherryMedia playersMedia player is a term typically used to describe computer software for playing backmultimediafiles. While many media players can play both audio and video, others focus only on onemedia type or the other. Such players are known as either audio players or video players and oftenhave a user interface tailored for the specific media type.Windows Media Player (abbreviated WMP) is a media player and media library applicationdeveloped by Microsoft that is used for playing audio, video and viewing images on personalcomputers running the Microsoft Windowsoperating system, as well as on Pocket PC and WindowsMobile-based devices. Editions of Windows Media Player were also released for Mac OS, Mac OSXand Solaris but development of these has since been discontinued.QuickTime is an extensible multimedia framework developed by Apple Inc., capable of handlingvarious formats of digital video, picture, sound, panoramic images, and interactivity. The classicversion of QuickTime is available for Windows XP and later, as well as Mac OS X Leopard and lateroperating systems. A more recent version, QuickTime X, is currently available on Mac OS X SnowLeopard, Lion, and Mountain Lion.VLC media player (also known as VLC) is a highly portablefree and open-sourcemedia player andstreaming mediaserver written by the VideoLAN project. It is a cross-platform media player, withversions for Microsoft Windows, OS X, GNU/Linux, Android, BSD, Solaris, iOS, Syllable, BeOS,MorphOS, QNX and eComStation.VLC media player supports many audio and video compressionmethods and file formats, including DVD-video, video CD and streaming protocols. It is able tostream over computer network and to transcode multimedia files.
By Sheilee CherryAspect ratioThe aspect ratio of an image describes the proportional relationship between its width and itsheight.It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, nomatter how big or small the image is, if the width is divided into x units of equal length and theheight is measured using this same length unit, the height will be measured to be y units. Forexample, consider a group of images, all with an aspect ratio of 16:9. One image is 16 inches wideand 9 inches high. Another image is 16 centimeters wide and 9 centimeters high. A third is 8 yardswide and 4.5 yards high.The most common aspect ratios used today in the presentation of films in movie theaters are 1.85:1and 2.39:1. Two common videographic aspect ratios are 4:3 (1.33:1), the universal video format ofthe 20th century and 16:9 (1.77:1), universal for high-definition television and European digitaltelevision. Other cinema and video aspect ratios exist, but are used infrequently.
