multimedia in plain words

In general sense, multimedia is just two or more media. Nevertheless, when most people refer to multimedia, they generally mean the combination of two or more continuous media, that is, media that have to be played during some well-defined time interval, usually with some user interaction. In practice, the two media re normally audio and video, that is, sound plus moving pictures.

AUDIO – An audio (sound) wave is a one-dimensional acoustic (pressure) wave. When an acoustic wave enters the ear, the eardrum vibrates, causing the tiny bones of the inner ear to vibrate along with it, sending nerve pulses to the brain. These pulses are perceived as sound by the listener.

VIDEO – The human eye has the property that when an image is flashed on the retina, it is retained for some number of milliseconds before decaying. If a sequence of images is flashed at 50 or more images/sec, the eye does not notice that it is looking at discrete images. All video systems exploit this principle to produce moving pictures.

abort, retry, ignore poem

The infamous Abort, Retry, Ignore message box of Windows, with no option given to close it. Found this classic and fun poem about the "Abort, Retry, Ignore" message. I have been able to trace back the source to Annoyances.org. Here it is: Once upon a midnight dreary, fingers cramped and vision bleary, System manuals piled high and wasted paper on the floor, Longing for the warmth of bed sheets, still I sat there doing spreadsheets. Having reached the bottom line I took a floppy from the drawer, I then invoked the SAVE command and waited for the disk to store, Only this and nothing more. Deep into the monitor peering, long I sat there wond'ring, fearing,
 Doubting, while the disk kept churning, turning yet to churn some more.
 But the silence was unbroken, and the stillness gave no token.
 "Save!" I said, "You cursed mother! Save my data from before!"
 One thing did the phosphors answer, only this and nothing more,
 Just, "Abort

an inflating flashbag

This is a flash drive. A flashbag, more accurately. When it is empty, it is slim and as data is filled into it, the bag starts to inflate until it is full. How ingenious! The creators have applied micro- pumps to achieve this, as stated in their site . When the device is about to blow off, it gives a message - "There is not enough free space". At times when it is not plugged in, it remains inflated relative to the amount of data it is holding. There are other innovative products from the creators of flashbag - such as C'ALL future phone , Balloophone , AllTunes , GMEA , Trings and Remobeads . Great, PlusMinus ! Kudos to your grey cells.
