How can be erase data stored in ROM?

A standard ROM or PROM cannot be erased, only erasable PROM can be erased. It is done with either UV light or electronically depending on the type of EPROM.


What type of light bulb emits UV rays?

Ultraviolet (UV) light bulbs emit UV rays.


Is UV light hot?

UV light itself does not produce heat, so it is not hot. UV light is a type of electromagnetic radiation that is invisible to the human eye.


Are UV light and UV rays the same thing?

Yes, UV light and UV rays refer to the same thing - ultraviolet radiation. UV radiation is a type of electromagnetic radiation that is not visible to the human eye. UV light or UV rays are terms used to describe this form of radiation.


How can uv light cause more than one type of effect?

UV light is a type of radiation that generally has negative consequences on living cells.


Is UV light the same as sunlight?

UV light is a component of sunlight, but sunlight also contains other types of light. UV light is a type of electromagnetic radiation that is not visible to the human eye.


What is the difference between PROM and EPROM?

EPROM (Electronic Programmable Read Only Memory) chips can be erased if it needs to be updated or fixed. It can be erased electronically only These are comparatively expensive than PROMs. PROM (Programmable Read Only Memory) chips are relatively once written and to rewrite them you need to replace entire data on it. These are relatively less costly. PROM is the Programmable ROM that allows the user to store data. an instrument called a PROM programmer does the storing by 'burning in', once the data has been burned, the data cannot be erased! On the other hand, an EPROM allows the data to be erased by the help of uv lights. i.e EPROM is uv light erasable and electrically reprogrammable.


Can polystyrene pass UV light?

Polystyrene does not transmit UV light very well as it is a type of plastic that is typically opaque to UV radiation. UV light tends to be absorbed or reflected by the polystyrene material rather than passing through it.


What is the most effective type of light that kills bugs?

The most effective type of light that kills bugs is ultraviolet (UV) light. UV light attracts insects and disrupts their biological processes, ultimately leading to their death.


What are the key properties and applications of UV transparent plastic?

UV transparent plastic is a type of material that allows ultraviolet (UV) light to pass through it. It is commonly used in applications where UV light needs to be transmitted, such as in UV sterilization equipment, UV curing systems, and UV light filters. Key properties of UV transparent plastic include high transparency to UV light, good chemical resistance, and durability.


What emits UV light?

Objects that emit UV light include the sun, black lights, and certain types of artificial light sources such as UV lamps and LEDs. UV light is a type of electromagnetic radiation that is not visible to the human eye but can cause fluorescence in certain materials.


What type of light from sunlight is absorbed by ozone?

Ultraviolet (UV) light from the sun is absorbed by ozone in the Earth's atmosphere. Specifically, ozone absorbs UV-B and UV-C wavelengths of light, providing a protective layer that shields the planet's surface from harmful radiation.
