Whenever UV light of a specific frequency is passed through, it burns the previously stored data and thus empties it to be filled with another program. However, to erase the previously stored data, ultraviolet (UV) rays are required.
EPROM: Erasable Programmable Read Only Memory (EPROM), unlike PROM, allows for writing and rewriting several times.Using a PROM, a computer geek can program it once with the help of a special tool called a programmer, wherein he burns a specific program into the memory that cannot then be rewritten. PROM: Programmable Read Only Memory (PROM) is a blank version of ROM that can be written/modified just once.This memory is usually soldered onto the main circuit board of the smartphones and cannot be replaced. It is technically called eMMC which stands for embedded multi-media card. When it comes to smartphones, ROM is generally referred to as the internal storage capacity. It’s fair to say that if it weren’t for ROM, you wouldn’t ever be able to fire up your computer. ROM: Read Only Memory Commonly referred to as Read Only Memory, ROM retains its contents even after the computer is turned off that’s why a computer can be switched on in the first place. It contains the programming that helps a computer or smartphone ‘boot up’. ROM, on the other hand, is a type of memory where data has been pre-recorded. Their replaceability makes them suitable for computer systems whose memory modules can be replaced/upgraded. DRAM is comparatively cheaper than SRAM, but the operating speed is slow. DRAM: Dynamic random access memory (DRAM) is a type of RAM that stores data using a pair of transistors and capacitors.It is generally not replaceable by the end user. SRAM is generally used as a cache memory for processors. SRAM: Static random access memory (SRAM) is a type of RAM that stores data using a 6- transistor memory cell.Now, let’s look at two main types of RAM available in the market. These days, motherboards come with more than one RAM slot, which gives you the flexibility to increase your RAM capacity, enabling better operational speed and computational performance. RAM: Random Access Memory If you ever open up your computer cabinet (computer tower), you will find one (or two) oblong chips installed in a slot on the motherboard. However, there’s a fair amount of the populace that can’t really distinguish between RAM and ROM and wouldn’t be able to explain how they function differently! As always, let’s brush away the cobwebs surrounding these common and useful tech terms. You certainly would have learned about them in your computer class, or perhaps you recognize the terms and at least know they are related to computer memories. That being said, RAM is more commonly encountered by the common person. If you’re not an alien reading this from a galaxy far, far away, then you have probably heard these terms countless times- RAM and ROM. ROM can hold data even without electricity, while RAM needs electricity to hold data.
ROM is a form of permanent storage, while RAM is a form of temporary storage.The differences between ROM (Read Only Memory) and RAM (Random Access Memory) are: ROM is a type of computer memory that stores data that has been pre-recorded. RAM is a type of computer memory that stores data that is currently being used so that the processor can access it quickly.
