What Kind of Data Can Be Lost When A Computer Is Turned Off?
The Data which is lost or have the chance to be lost when the computer is turned off is RAM (random access memory) and the reason is RAM is a volatile memory it is not fixed but a changeable memory while the ROM (read-only memory) is non-volatile it is fixed and only change when the developer wants to change.
A data is a computer is stored in different manners and the memory is the primary place and the data is stored in a manner that it is accessible by the CPU of the computer. RAM is the fast storage place where data can be achieved very easily with not much delay. The RAM is a direct connection with the CPU through the memory bus and the data can be accessed by it quickly. The data for the active program and the OS all are stored in the RAM. That’s why because of the flexibility the RAM losses the data when the power is turned off. The data stored in ROM is related to the instruction to start the program and for the computer initiation .in the case of the full storage of the ROM than the virtual memory is used because it is slower than the RAM.
Let’s discuss the types of memory who has the chance to lose when the computer is turned off in the following:
Main RAM:
The Main RAM has different characters than the volatile RAM. the browser, word processor, and different programs all use it as the scratchpad in a manner to add remove or update the data in it. Millions of the small transistors enveloped in the integrated chips are present in the main RAM. It works at a high speed, and the chance of it being lost at the time of the power loss is high.
Cache RAM:
In the main memory, the microprocessor has the extra memory units which are called a cache and they are at the three stages of the cache L1, L2, and L3 and the speed of the working is up to 1 billion of a second or as we say 60 to 80 times more than the regular RAM.it is quite expensive than the regular RAM and the microprocessor has the million or fewer characters of this memory. But like the standard RAM, it has the chance to be lost when the computer is turned off.
