A type of PROM (Programmable Read-Only Memory) called EPROM (Eraseable Programmable Read-Only Memory) is a chip that, after being programmed, can be exposed to strong ultraviolet light in order to erase it. They're recognized by the transparent window on the top surface through which you can see the silicon chip. It's through this window that UV enters to erase the chip.

What does the light with a car with a key in it mean?
This indicator light is related to the vehicle security system, which checks that the key you are using is authentic (has a de-immobilizer chip). In normal operation, it will stay lit for a few seconds and then go out. If it is flashing, you have a key with no chip in it, a bad ring antenna, or other fault in the security system.

What is flash memory and how does it relate to computers?
A flash memory is basically your computer chip that can be electrically erased and reprogrammed And it relates to your computer because you wouldn't be able to do anything if you didn't have it

How are the characteristic a ROM chip different from those of a RAM chip?
A RAM Chip (Random access memory) loses it's stored information when power is lost. A RAM chip can have data written to it. A ROM Chip (Read Only memory) does not lose it's information when power is lost, but it cannot be written to* * There are different types of ROM... ROM (Read Only memory) gets "burned" and cannot be changed. PROM (Programmable Read Only Memory) (not sure if they're used much any more) can be erased by exposing to ultra-violet light and re-programmed. EPROM (Electrically Programmable Read Only Memory) - can be re-written electrically with special software.
A ROM chip that can be programmed over and over using ultraviolet is known as what?
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer.
How do LED flashlights create light?
An LED flashlight produces light in the same as any other LED light bulb. An LED light source is actually a special kind of chip called a semiconductor. As current is passed directly over the positively and negatively charged sides of the semiconducting chip, the electrons emit photons, or light. Over the chip usually placed a lens and surrounding it is a reflector which enhances and spreads the LED's light.
