The internal hard-drive, USB flash drive, external hard-drive can all be used to save data, provided the document (for example) has been saved occasionally while the document was being worked on. If working in RAM (Random Access Memory) the data is lost as soon as the power is turned off, as RAM is a volatile memory, unless a battery back-up system is used.
What else can I help you with?
What is volatility in computer?
It is the level of secondary storage that retains data when power is turned off. For example: Memory is volatile if it loses its data when the power is removed.
What is the primary advantage in file?
It stores data, even when the computer is switched off.
When you save to your data will remain intact even when the computer is turned off?
of course not!
Read only memory - keeps its memory even when the computer is turned off?
Yes, ROM (Read Only Memory) retains its contents even when the computer is turned off. RAM (Random Access Memory), on the other hand, loses its content the instant power is switched off.
What is ROM in a computer and how does it differ from other types of memory?
Read-only memory (ROM) in a computer is a type of non-volatile memory that stores data permanently and cannot be easily modified or erased. Unlike random-access memory (RAM) which is volatile and temporary, ROM retains its data even when the computer is turned off. ROM is typically used to store essential system software and firmware that is necessary for the computer to function properly.
What is permanently installed mechanism inside the computer that stores all data that is put into the computer even after the computer is turned off?
Secondary Storage Devices (such as Harddisk drives) which are non-volatile in nature stores all data that is put into computer even after the computer is truned off.
Storage that retains its data after the power is turned off is referred to as?
non-volatile storage
What is an IDE data cable used for?
To connect secondary storage devices and to save the data permanently even while computer is turned off.
Will you erase everything off your digital video recorder - DVR - if you unplug it?
No... Your DVR uses hard drive technology that saves data to a disk that retains its contents even if unpowered.
Is cache memory non volatile memory?
No, cache memory is a volatile type of memory, meaning the data stored in cache memory is lost when the power is turned off. Non-volatile memory, on the other hand, retains data even when the power is turned off.
Can Ram be used to backup files?
Generally, no. RAM is volatile memory, which means that all data there will be lost when the computer is powered off. Normally your computer only uses it for data (and programs) which is currently in use. But there ARE devices that use RAM for data storage (e.g. PDAs and some fancy solid-state drives). These devices usually provide a battery to power the RAM when the device is turned off. Note that DVD-RAM is a rewritable non-volatile media. It retains its data when powered off but you can change the data later.
Can you backup your data even with viruses on the computer?
Yes you can. No matter what you do you can usually get stuff back off your hard drive.
