What type of memory can hold data for long periods of time even when the computer is off?

Nonvolatile memory.
For small amounts of memory a nonvolatile memory can be created by using conventional semiconductor CMOS static RAM ICs with battery backup (this is used in the CMOS memory on Windows computers and the PRAM on MacOs computers).
For medium amounts of memory semiconductor NOVRAM ICs can be used, but they contains both SRAM and EEPROM in the same IC package and requires a "warning signal" from the power supply to copy the contents before power actually fails.
For large amounts of memory magnetic memories are about the only way (e.g. ferrite magnetic core, Spin-Torque MRAM ICs, magnetic tunnel junction MRAM ICs).
ROM and Flash memory are nonvolatile, but are too slow on writes for practical use.

What part of the computer holds data for long periods of time even when there is no power to the computer?
Secondary Storage or Hard Drive
What are two types of computer memory and their function?
The 2 types of computer memory are ROM and RAM. These stand for Read Only Memory and Random Access Memory, respectively. Read Only memory is the type of memory that is non-volatile, which means that the data contained here is never lost, even when the computer is shut down. RAM on the other hand is the type of memory which is volatile-- which can be lost the moment the computer is turned off. It temporarily just stores the data that's being processed when the computer is on.
What is the Difference between prom and RAM?
PROM is "Programmable Read Only Memory" RAM is "Random Access Memory" Prom is used to retain data even when the computer is turned off. RAM is used by the computer to run applications when the computer is running. RAM is high speed memory that can be read/written while the computer is running. Applications and data are loaded into RAM every time your computer is turned on. PROM, ROM, EPROM are all versions of memory that typically contain the same data every time the computer is turned on.
Where The information stored in RAM is erased when the computer is turned off?
Main computer memory is called volatile memory. It holds data only as long as it is provided power. When you turn off the computer, you remove power from the memory chips and they loose the ability to hold data. If you want to keep your information, ensure you save it to the computer hard drive before you switch off the computer.
What is the difference between volatile memory and non volatile memory?
volatile memory: The data is lost on reboot. This is the ram memory. Random-access-memory.non-volatile memory: The data is saved to a hard drive or flash drive, or it could be a hard coded chip. This is ROM memory. Read-only-memory.Volatile memory: you will lost all of your data when your electricity go out. Ram is volatile memory. When you shutdown your computer. Info that haven't saved is destroyed.Nonvolatile memory: All data that stored in this type of memory wil retain when you shutdown your computer. Rom is of type nonvolatile memory.Non-volatile holds its data even when the power is turned off.Volatile memory: you will lost all of your data when your electricity go out. Ram is volatile memory. When you shutdown your computer. Info that haven't saved is destroyed.Nonvolatile memory: All data that stored in this type of memory wil retain when you shutdown your computer. Rom is of type nonvolatile memory.
What is the use of paged memory?
Paged memory is used to extend the real physical memory of the machine by copying blocks of data from the memory to a drive. That way you can run many programs simultaneously even if they consume more memory than you physically have in your computer. When a program requires to access the data that is "paged to disk" the operating system will read this data into memory.
What is the different between volatile and non volatile?
Volatile memory is temporary memory that is lost when then computer is shut off (RAM). Non-volatile is permanent memory that that holds its data even when the computer is shut off (ROM, NVRAM). Volatile memory is memory that disappears after you turn off your computer RAM is a big example of that because all the memory on RAM disappears after you turn off your computer. Non-Volatile memory is memory that even if you turn off your computer it will still be there. A huge example of that is hard drive memory. volatile= disappears after the computer is turned off Non-Volatile= never disappears.
What does flash drive means?
The amount of data/information the flash drive can store at one time.
ROM preserves its contents even when the computer is what?
Off ROM (Read Only Memory) is typically used to write permanent data or instructions to a system for use even after the computer is turned off. Examples of ROM are your BIOS and Firmware
Describe the main types of primary and secondary storage?
Primary storage includes Random access memory (RAM) which is fast and volatile. Secondary storage consists of devices like hard disk drives (HDD) and solid-state drives (SSD) which are slower but non-volatile, allowing data to be stored for longer periods even when the power is turned off.
What is a flash stick?
A "flash stick" is another word for a USB flash drive. The term "flash" is used because it consists of flash memory data storage. Flash memory is is a non-volatile computer storage (computer memory that can retain the stored information even when not powered) that can be electrically erased and reprogrammed.
Why computer does not run without memory?
because the computer has no where to store it's files. The computer wont even start up without memory.
