What differenc between ROM and RAm?
ROM isn't erased when you turn the power off, whereas RAM is.
What is the memory that holds items that can be read but not erased or changed?
Rom
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 is memory that cannot be changed or erased?
Read Only Memory or ROM. There are also Erasable ROMs called EPROMs, EAROMS, EEROMS, and Flash Memory. The erasable ROMS will only be erased under special circumstances, and when in use they act the same as a normal ROM.
Which type of ROM can be erased by UV light?
The type of ROM that can be erased by UV light is called a PROM (Programmable Read-Only Memory). PROM chips have fuse links that can be erased using UV light, allowing the chips to be reprogrammed.
What is correct CD-rom?
CD rom means: Compact Disc-Read-Only MemoryIt's a disk that cannot be erased, only read.
What is a type of ROM that is erased in blocks and currently holds a system's BIOS?
Flash EPROM
Which type of rom can erased and re-written without having to remove the chip from the computer?
An EEPROM chip
What is the permanent memory chip inside your computer called?
"Permanent" memory is called ROM. ROM stands for Read Only Memory. Under normal circumstances, ROM can not be modified or erased, even if the computer loses power.
WHAT is ultraviolet E PROM?
A type of ROM(Read Only Memory) which can be programmed and can be erased after programming using ultraviolet rays.
What is rom define its types?
ROM: Read Only Memory. Rom is memory that normally can only be read, but not written to. Types of ROM: 1. ROM: Basic, hard-coded ROM that has its data implanted at the time of manufacture. 2. PROM- Programmable ROM: Usually is manufactured as blank ROM, and can be written to 1-time by 'burning' fuse links inside the device. 3. EPROM- Erasable Programmable ROM: A PROM device that can be erased through some means. This term is not generally used, as a more-specific method of erasing is usually part of the acronym (See EEPROM and MPROM below). A chip that can be erased by applying light to a window may use this term. 4. EEPROM- Electronically Erasable Programmable ROM: This indicates that the ROM device is erasable through an electronic signal, applied to an "Erase" input. When the correct logic signal (high or low depends on manufacture of the device), the device is "erased" back to it's default state. 5. MPROM- Magnetically Erasable Programmable ROM: This is similar to an EEPROM, except that the device is erased by exposing it to a magnetic field. Another use of the term 'ROM' is CD-ROM (or DVD-ROM). This is a removable media format that is contained on an optical disk. As these discs can only be written to once, they are considered to be Read-only memory. (Note that "rewritable" disks exist...they are commonly designated as "CD-RW" and "DVD-RAM" or "DVD-RW") and would be similar to an EPROM in application.
Why rom is non volatile memory?
ROM is involatile because its name means Read Only Memory, hinting that the data stored on it cannot be altered. The word involatile means long term and not changeable.
