​​Why are local disks in computers labelled with alphabets C, D, E and not with A and B?

Have you seen a floppy? Floppies were a type of disk storage used earlier before the current system of storage came into existence. Floppy disk drives were named with the letters A and B. When hard disk drives became standard in most computers, they were logically labeled 'C' since the first two letters were already used for these floppy drives. Though floppy disk drives are no longer widely used, hard disks are still labeled from 'C' onwards.

​​How does a Musical Water Fountain Works?

Image
A Musical Fountain, also known as a dancing fountain, is a type of animated fountain for entertainment purposes that creates an aesthetic design (including three-dimensional images). This is achieved by employing the effects of timed sound waves and timed light (including laser) against water particles.  Modern-day fountains employ a computer-controlled pneumatic arrangement, essentially a pressurized cylinder of water with the provision of an expulsion mechanism(like a piston) and a nozzle at the outlet that is programmed to squirt water with a specific force for a specific duration while the computer also manages the audio output. The circulation system is also modernized with the help of pressure sensors and pumps to maintain continuity.  Old school fountains used the principle of siphoning to maintain continuity where the water level was maintained slightly above the height of the canons that squirted water such that any drop in water level resulted in a siphoning suction being est

​​Why do we Hiccup?

Hiccups can be annoying but they’re usually short-lived. However, some people may experience recurrent episodes of persistent hiccups. At its most basic, a hiccup is a reflex. It happens when a sudden contraction of your diaphragm causes the muscles of your chest and abdomen to shake.

If you find yourself getting hiccups often, eating smaller meals and minimizing carbonated beverages and gassy foods might be helpful.

General Knowledge :

If you place your feet into a plastic bag with a piece of garlic, you'll be able to both tastes and smell the garlic after an hour. If you grind a marine sponge through a sieve into salt water, it'll reorganize itself back into a sponge. It's the only animal that we know of that can do that. Everyone is a genius at least once a year. A real genius has his original ideas closer together. If you are not learning constantly, you are not growing. If you are not growing, you are not succeeding.
