Tehnology of 2009

Like everything else that changes and has trends, so does technology. In a sense, that makes it no different from fashion, cars or anything else that comes and goes. Yet unlike those things, technology is always evolving. Newer and better all the time, smaller, faster, higher capability and capacity than the last. Technology helps us to make our work more faster and easier. It is also one means of entertainment and one of this is texting. Trend already changing communications with some clients is text messaging. Texting has become a preferred mode of correspondence with many, especially the younger set, and will be as standard as e-mail in the years ahead. It seems more likely to gain ground as a communications mode once a professional relationship is established.

Computer Ethics

I can say that computer ethics keeps the privacy of individual works like documents, files, software, music, or movies from copying or stealing . It is immoral or unethical stealing other works while they exerted efforts to make it. Their are so many immoral or unethical activities done using computers like stealing and destroying other files by using and spreading viruses to destroy other files, reading peoples e-mail messages and non-public files, stealing accounts of a company, writing in a way that is harmful to the society. For example, if you are working to an animation house, and producing animated films to children, you near responsible for their contents. Do the animation include scenes that can be harmful to the children.
