When the computer is switched off the data stored is Rom is lost?

If it's actually ROM, nothing should happen to it; ROM is read-only memory. It's possible that the circuits could be so badly designed that switching off power would cause a power surge through the ROM which would damage it, but any company that designed their boards that way deserves to go out of business, preferably by being sued into oblivion.

∙ 14y agoIt is read only memory meaning the contents can not be altered (written to) and it is non-volatile meaning the contents are not lost when the computer is turned off.

What happens to a computers main memory when the computer is turned off or rebooted?
All RAM (Random Access Memory) requires power to work. Once the computer is shut down, the power is lost, and so is all the data stored in the RAM. RAM is designed this way so that it remains incredibly fast. Standby made on Computers saves your current session to RAM, and continues to provide power to the RAM in order for it to continue remembering your session. If such power was lost, so would be your session. Hibernate mode on Computers, however, saves the session to the Hard Drive, which does not require power to remember things. This enables Hibernate to be so much more power efficient than Standby, although Standby is faster to resume.
Which is the most valuable a computer or data it contains?
The data; the data is what you place into the computer. Simply by having a computer doesn't make it valuable. You can always replace a computer, but you cannot replace the same data.
When you turn off the computer data stores where?
When your computer is shut down, the data is stored on your hard disc drive. RAM stores the operating system while the computer is running. Hard discs are non-volatile, so it will always be there. However RAM is volatile, and once you do not supply power to it, all memory is lost.
What is it ment by web - based storage?
It's simply storage away from a home or office computer. The data is uploaded to the internet, and stored on secure servers. If your home or office computer is lost or stolen, you can simply download everything back onto a new machine.
Can computers can only retain data temporarily?
Data held on the hard drive, is considered to be permanent. It will still be there, after the power has been removed for many years. Random Access Memory (RAM) is the working memory, held on microchips and needs power to keep the data. It will be immediately lost when the computer is switched off. This usually of little consequence as important data is always held on the hard drive. The RAM is only used for temporary data whilst working.
Programmes and data stored on RAM are lost when a computer is switched this type of memory is called?
volatile
What happens yo the data in RAM when the computer is switched off?
the information is lost after power is switched off.
What is storage back up in computing?
Storage back-up is where data stored on the computer is transferred to a disk or another drive, in case the data on the computer is lost.
How can data be stored in computer memory when switched off?
Memory means the RAM of the CPU and when your computer is switched off you can't save any form of data in your memory (RAM). This is because RAM is a place in the CPU's system where data is stored temporarily and it gets removed as soon as you turn off your CPU. (RAM requires a constant voltage to retain information.) So by turning the PC off, all data in the RAM is lost.
How could one restore data on their computer after it crashes?
"First, do a search on your computer for lost data. If you can't find it, then unfortunately, unless you've stored your date on an external hard drive or something other than the crashed computer, your data has been lost forever."
When you format a system it is asume that all the data are lost but how can you reetrive the data?
public switched telefone network
Why does a computer system need ROM?
Rom is a non-volatile memory. A computer system needs it because it stores the data permanently. If there is no ROM the data can be stored only until the system is on. Once the system is off, all the data stored in RAM(volatile memory) will be lost. So, ROM is used to store the data for a desired period of time.
What volatile thus the content is lost when the computer is switched off?
RAM
What is the unit of random access memory?
Random access memory (usually known by its acronym, RAM) is a type of computer data storage. It takes the form of integrated circuits that allow the stored data to be accessed in any order - that is, at random and without the physical movement of the storage medium or a physical reading head. RAM is a volatile memory as the information or instructions stored in it will be lost if the power is switched off.source: Wikipedia
What happend to data stored in a computers RAM if the computers power is accidentally switched off?
A data file in RAM when your computer loses power just goes away forever. It cannot be retrieved, because RAM is a temporary spot, not a permanent one.
What does volatile RAM mean?
RAM = Random Access Memory. The memory used in a computer to hold programs and data while it is running. This memory is said to be 'volatile' because when the computer is switched off and there is no power available to the memory all the stored information is lost. With 'non-volatile memory' (such as used in a USB memory stick) when the power is removed the data remains as it was and can be accessed again when power is restored.
