Here we are trying to eradicate some of your technical myths.

Magnet near a PC can spoil some components: This is generally a very common myth that a magnet placed near a PC is harmful for some of its components. This was absolutely accurate in case of a floppy drive. The floppies have a magnetic coating on its storage area. A magnet placed near it can really data spoiled in a floppy. But, this is not true in case of hard drives, laptops, memory cards etc., this is just an illusion nothing else. They are just immune to magnetic radiations. of course if a magnet is placed near a CRT we do see some discolouration of the display, which is because the CRT usees a magnetic field to control and direct the Cathode rays onto the picture tube. Although prolonged exposure of the CRT to a powerful magnet may cause some depreciation in the efficiency of the CRT there is no short term effect as such.

Stop' a USB device before unplugging: Another technical myth is about USB device. It is believed that removing USB from an unplugged device can corrupt data stored in a USB. Actually,

it is absolutely safe and sound to remove a USB, when it is idle

This is the same case like we can easily remove a keyboard, a mouse, printer or a scanner from a computer when they are not in use.

Computer monitor emit harmful radiation: Some computer users think that a monitor emits harmful radiations that can cause dangerous diseases like skin cancer and brain tumor. But actually this assumption is absolutely wrong. No doubt a monitor emits some radiations and prolonged exposure to those radiations at short distances may cause eye strain, but the rays emitted are so weak that they can’t cause any harmful disease.

A high-speed flash cards in a digital camera lets you take photos faster: This is an illusion at best, some users think that high speed flash card aids in clicking photos in fast speed.
