HISTORY OF COMPUTER DATA STORAGE A STAGE BY STAGE PICTORIAL PRESENTATION
HISTORY OF COMPUTER DATA STORAGE A STAGE BY STAGE PICTORIAL PRESENTATION F rom the beginning of mankind, man tried to find a way to store information for the following generations. When people nowadays hear the word storage or computer storage they normally think aboutCD Rom, USB key or DVD. Things like the floppy disk or the punch card are nearly forgotten. In fact, the history of information storage goes back to pre-historic times where mankind used red and yellow ochre, hematite, manganese oxide and charcoal to paint information about their life on rock walls, caves and ceilings. N owadays we are used to having hundreds of gigabytes of storage capacity in our computers. Even tiny MP3 players and other handheld devices usually have several gigabytes of storage. This was pure science fiction only a few decades ago. For example, the first hard disk drive to have gigabyte capacity was as big as a refrigerator, and that was in 1980. Not so long ago...
Dear Friends,
ReplyDeleteThis video shows the effect of Nonlinearity in a simple pendulum you can watch out the oscillations in the video.U have to follow its continuous oscillation upto 36 seconds after that the oscillation break up into three different styles and it revert back to its continuous form and combined three into one wave after 1.20 seconds so in between the time limit 36 to 1.20 the oscillatory system behaves under Nonlinear force.
Hope u all understand the effect of Nonlinearity.
Best wishes,
