PROMs can only be programmed once. They are more fragile than ROMs. A jolt of static electricity can easily cause fuses in the PROM to burn out, changing essential bits from 1 to 0.

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.
What are the disadvantages of ROM?
ROM or "read-only memory" cannot be altered. Once a ROM chip or other ROM media is created, it cannot be changed by user-accessable means and is therefore inflexible.
What is the physical part of the PC that keeps track of the hardware resources on the system is the?
the ROM BIOS chip
Where would you look for a computer's startup information?
your ROM chip
The process of upgrading or refreshing the ROM bios chip is called ROM?
The process of upgrading or refreshing the ROM BIOS chip is called flashing BIOS. The power menu in BIOS setup allows you to configure automatic power saving features.
What is programmed chip?

What is an M66t?
The M66T is an IC chip that works as a simple melody generator which has an onboard ROM that is programmed for musical performance in telephones and musical toys.

the ROM BIOS chip
The ROM bios chip is the most important chip on the motherboard?
Yea the CPU,and the ROM bios chip is the most important chip on the motherboard,even the dma also.
Why is an operating system software handed from hard disk then a Rom chip?
The operating system has nothing to do with the ROM chip
What chip in a printer contains data for fonts?
The ROM Chip
An embedded operating system resides on what chip?
A ROM chip
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.
does ROM exist as a chip on the motherboard?
Yes. Every motherboard has a Rom chip on it. Typically, the one most noteworthy is the Rom chip that holds the information for the motherboard. It carries boot instructions, the setup program, BIOS programs, and POST routine. This chip is usually not altered. Older motherboards carried removeable ROM chips that could be replaced, but are now mostly onboard or soldered on permanently.
