Some of the advantages of information technology include:
Globalization - IT has not only brought the world closer together, but it has allowed the world's economy to become a single interdependent system. This means that we can not only share information quickly and efficiently, but we can also bring down barriers of linguistic and geographic boundaries. The world has developed into a global village due to the help of information technology allowing countries like Chile and Japan who are not only separated by distance but also by language to shares ideas and information with each other.
Communication - With the help of information technology, communication has also become cheaper, quicker, and more efficient. We can now communicate with anyone around the globe by simply text messaging them or sending them an email for an almost instantaneous response. The internet has also opened up face to face direct communication from different parts of the world thanks to the helps of video conferencing.
Cost effectiveness - Information technology has helped to computerize the business process thus streamlining businesses to make them extremely cost effective money making machines. This in turn increases productivity which ultimately gives rise to profits that means better pay and less strenuous working conditions.
Bridging the cultural gap - Information technology has helped to bridge the cultural gap by helping people from different cultures to communicate with one another, and allow for the exchange of views and ideas, thus increasing awareness and reducing prejudice.
More time - IT has made it possible for businesses to be open 24 x7 all over the globe. This means that a business can be open anytime anywhere, making purchases from different countries easier and more convenient. It also means that you can have your goods delivered right to your doorstep with having to move a single muscle.
Creation of new jobs - Probably the best advantage of information technology is the creation of new and interesting jobs. Computer programmers, Systems analyzers, Hardware and Software developers and Web designers are just some of the many new employment opportunities created with the help of IT.
Some disadvantages of information technology include:
Unemployment - While information technology may have streamlined the business process it has also crated job redundancies, downsizing and outsourcing. This means that a lot of lower and middle level jobs have been done away with causing more people to become unemployed.
Privacy - Though information technology may have made communication quicker, easier and more convenient, it has also bought along privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge.
Lack of job security - Industry experts believe that the internet has made job security a big issue as since technology keeps on changing with each day. This means that one has to be in a constant learning mode, if he or she wishes for their job to be secure.
Dominant culture - While information technology may have made the world a global village, it has also contributed to one culture dominating another weaker one. For example it is now argued that US influences how most young teenagers all over the world now act, dress and behave. Languages too have become overshadowed, with English becoming the primary mode of communication for business and everything else.

v.i.d.e.o editing
The term video editing :
- non-linear editing system, using computers with video editing software
- linear video editing, using videotape
Video editing is the process of re-arranging or modifying segments of video to form another piece of video. The goals of video editing are the same as in film editing — the removal of unwanted footage, the isolation of desired footage, and the arrangement of footage in time to synthesize a new piece of footage.
Early video recorders were very expensive, and the quality loss of copying was so great, that 2 inch Quadruplex videotape was edited by visualizing the recorded track with ferrofluid, cutting with a razor blade or guillotine cutter and splicing with tape. Improvements in quality and economy, and the invention of the flying erase head, allowed new video to be inserted cleanly into an existing tape. This technique was referred to as linear editing. If an early scene needed to be lengthened, all the later scenes would need to be added again. Multiple sources could be played back simultaneously through a vision mixer to be mixed or keyed.
Modern non-linear editing systems are computer-based, though there was a transitional analog period using multiple source VCRs or LaserDisc players. Footage is played into a computer and captured on a hard drive. Editors use software such as Avid's Media Composer and Xpress Pro, Apple's Final Cut Pro, and Adobe's Premiere to manipulate the captured footage. High definition video is becoming more popular and can be readily edited using the same software along with related motion graphics programs. Clips are arranged on a timeline, music tracks and titles are added, effects can be created, and the finished program is "rendered" into a finished video. The video may then be distributed in a variety of ways including DVD, web streaming, Quicktime Movies, iPod, CD-ROM, or videotape.
For the home market, consumer-friendly products such as Adobe Premiere Elements, AVID Express DV, CyberLink PowerDirector, Final Cut Express, Sony Vegas, Pinnacle Studio, ULead VideoStudio, Roxio Easy Media Creator, Magix Movie Edit Pro and muvee autoProducer have come on the market with the emergence of computer video editing for the home PC. Two free programs that are bundled with computers are Apple's IMovie and Microsoft's Windows Movie Maker.

you TUBING
This was what i learned ...you tube..kinda useful for us future teachers not?...there are lots of materials up thr..we just need to adapt n adopt..easy =)..have fun peeps..a good add on to out learning portfolio for dis sem!
(an artical about you tube..a short 101)
YouTube is a video sharing website where users can upload, view and share video clips. YouTube was created in February 2005 by three former PayPal employees. The San Bruno-based service uses Adobe Flash Video technology to display a wide variety of user-generated video content, including movie clips, TV clips and music videos, as well as amateur content such as videoblogging and short original videos. In October 2006, Google Inc. announced that it had reached a deal to acquire the company for US$1.65 billion in Google stock. The deal closed on November 13, 2006.
Unregistered users can watch most videos on the site, while registered users are permitted to upload an unlimited number of videos. Some videos are available only to users of age 18 or older (e.g. videos containing potentially offensive content). The uploading of videos containing defamation, harassment, commercial advertisements and material encouraging criminal conduct is strictly prohibited. Related videos, determined by title and tags, appear onscreen to the right of a given video. In YouTube's second year, functions were added to enhance user ability to post video 'responses' and subscribe to content feeds.
Few statistics are publicly available regarding the number of videos on YouTube. However, in July 2006, the company revealed that more than 100 million videos were being watched every day, and 2.5 billion videos were watched in June 2006. 50,000 videos were being added per day in May 2006, and this increased to 65,000 by July.In January 2008 alone, nearly 79 million users had made over 3 billion video views.
In August 2006, The Wall Street Journal published an article revealing that YouTube was hosting about 6.1 million videos (requiring about 45 terabytes of storage space), and had about 500,000 user accounts. As of April 9, 2008, a YouTube search returns about 83.4 million videos and 3.75 million user channels. It is estimated that in 2007, YouTube consumed as much bandwidth as the entire Internet in 2000, and that over 13 hours of video are uploaded every minute. In March 2008, its bandwidth costs were estimated at approximately $1 million a day.
As of Q1 2008, YouTube was not profitable, with its revenues in 2007 being noted as "not material" by Google in a regulatory filing. Exact revenue or profit numbers are not published, but a June 2008 Forbes magazine article projected the 2008 revenue at $200 million, noting progress in ad sales. At that time, the price for an ad on the YouTube home page was $175,000 per day (plus a $50,000 commitment to buy Google/YouTube ads elsewhere), and a branded channel (distinguished by a customized background) cost advertisers $200,000.

audio EDITING
Audio editing
Audio editing is the process of taking recorded sound and changing it directly on the recording medium (analog) or in RAM (digital).
Audio editing was a new technology that developed in the middle part of the 20th century with the advent of magnetic tape recording. Prior to magnetic tape, editing (and the repairing of breaks) was performed on wire recorders with solder and extra wire to reinforce the new joint. After World War II, reel-to-reel tape machines became prevalent and edits were made with straight razors and "splicing" tape to connect pieces of magnetic tape that had been cut. Audio editors would listen to recorded tapes at low speeds, and then located specific sounds using a process called scrubbing, which is the slow rocking back and forth of the tape reels across the playback heads of the tape deck.
With the development of microcomputer technology, sound recordists were able to digitize their recordings and edit them as files within a computer's RAM. The earliest audio editor was written by Soundstream Inc specifically for the PDP-11 minicomputer platform. Digital audio workstations appeared using proprietary software and hardware solutions but after the personal computer became widely available in the mid '80s, much the power of a DAW came into the hands of home and small business users through software audio editing programs written specifically for personal computers. The earliest program to become widely used in this application was a wave editor called Sound Designer in the late 1980s and early 1990s. Sound Designer was created by a company called Digidesign who achieved early industry dominance. Today, the most popular retail audio editing programs not associated with specific hardware are: Audacity, Adobe Audition, Sound Forge, Samplitude, Adobe Soundbooth and Goldwave.[citation needed]
In recent years, with the growing popularity of GNU/Linux, a number of Free software software projects have sprung up in order to develop an open source audio editing program. This movement has been bolstered recently by the development of ALSA, and the Linux low latency kernel patch, which allow the GNU/Linux Operating System to achieve audio processing performance equal to that of commercial operating systems. The multi-platform package Audacity is currently the most fully-featured free software audio editor.

what is photoshop?!?!
Adobe Photoshop, or simply Photoshop, is a graphics editing program developed and published by Adobe Systems. It is the current and primary market leader for commercial bitmap and image manipulation, and is the flagship product of Adobe Systems. It has been described as "an industry standard for graphics professionals" and was one of the early "killer applications" on Macintosh.Photoshop CS3, the current tenth iteration of the program, was released on 16 April 2007. "CS" reflects its integration with other Creative Suite products, and the number "3" represents it as the third version released since Adobe re-branded its products under the CS umbrella. Photoshop CS3 features additions such as the ability to apply non-destructive filters, as well as new selection tools named Quick Selection and Refine Edge that make selection more streamlined. On April 30th, Adobe released Photoshop CS3 Extended, which includes all the same features of Adobe Photoshop CS3 with the addition of capabilities for scientific imaging, 3D, and high end film and video users. The successor to Photoshop CS3, Photoshop CS4, will be the first 64-bit Photoshop on consumer microcomputers.
