Similarities between ram and rom?
There are none as RAM allows random write access while ROM only allows read access (the very reason why it's called ROM because it stands for Read-Only Memory).
Similarities between the ulna and the radius?
what is the similarities between the ulna and the radius
What is the similarities between for and while statement?
similarities
What are the similarities between a switch and a hub?
what are the similarities between network switch and a hub
What is the similarities between imperialists and anti-imperialists?
There are zero similarities between the two.
What is the explanation for the four types of ROM?
ROM- read only memory.. types are masked rom, prom, eprom and eeprom.
What are the kind of ROM?
ROM can be broadly of three types, namely PROM (programmable read only memory), EPROM (erasable PROM), and EEPROM (electrically EPROM). Many versions of EEPROMs are available.
What type of rom it is sim card?
A SIM card (subscriber identity module) is similar to an EPROM (erasable-programmable ROM), with anywhere between 8 KB to 256 KB of storage capacity.
What similarities exist between ROM and a secondary computer?
None whatsoever.
What is a type of ROM that is erased in blocks and currently holds a system's BIOS?
Flash EPROM
What are the 2 main types of ROM called?
PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory)
What are examples of primary memory?
examples of primary memory are RAM, ROM, PROM, EPROM , etc.....
What is the classification of ROMs?
Rom :- Read Only Memory. The storage of data and instructions in Rom is permanent. It does not depend on the power supply. The memory which does not lose its content when power is turned off is known as non-volatile memory. There are three types of Rom :- Prom = Programmable read only memory Eprom= Erasable Prom EEprom=Electrically erasable prom
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.
Can ROM be erased or added to?
No. However there are forms of ROM that can be changed, like Programmable Read Only Memory (PROM) and Erasable Programmable Read Only Memory (EPROM).
Why eeprom is better than eprom?
The advantages were "accumulative", so a history of the development of ROM is best to explain them: First came ROM - Read-Only Memory. Unlike RAM, ROM could not be written to but had the advantage that it was non-volatile which means its contents are permanently there, they do not disappear when power is removed. But the contents were put there in the factory, you could not "program" the contents yourself. Then came PROM - Programmable ROM. With PROM you could, if you owned a programming machine or "programmer", set the contents of the PROM yourself, one time, before your put it in the electronic circuit board. Next came EPROM - Eraseable PROM - with EPROM if you needed too you could take the EPROM out of the circuit board, put it in an EPROM eraser to reset the contents, and then program it again in the programmer. The EPROM eraser was a small box that the EPROM was placed inside. When the box was turned on ultra-violet light shined into the EPROM thorough a small "window" on the top of each EPROM, erasing the contents. Finally came EEPROM or E2PROM - Electronically Erasable PROM. With EEPROM you didn't need the eraser or the programmer! The EEPROM can be programmed, again and again while it is on the circuit board, by sending a sequence of signals to certain pins on the device.
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.
