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.
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.
Computer memory that requires power is known as volatile memory. This type of memory, such as Random Access Memory (RAM), retains data only while the device is powered on. Once the power is turned off, any information stored in volatile memory is lost. In contrast, non-volatile memory, like hard drives or SSDs, retains data even when power is removed.
It stores data, even when the computer is switched off.
of course not!
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.
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.
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.
non-volatile storage
The contents of these chips are lost when the computer is switched off because they use volatile memory, such as RAM (Random Access Memory). Volatile memory requires a constant power supply to maintain the stored data; when the power is cut off, the data is erased. In contrast, non-volatile memory, like hard drives or SSDs, retains data without power.
To connect secondary storage devices and to save the data permanently even while computer is turned off.
The part of a computer that stores data, programs, settings, and the operating system while the computer is off is the hard drive or solid-state drive (SSD). These storage devices retain information even when the power is turned off, allowing for data retrieval when the computer is powered back on. In contrast, RAM (random access memory) only holds data temporarily while the computer is on.
No... Your DVR uses hard drive technology that saves data to a disk that retains its contents even if unpowered.
