The BIOS stores the date, the time, and your system configuration information in a battery-powered, non-volatile memory chip, called a CMOS (Complementary Metal Oxide Semiconductor) after its manufacturing process.
Is BIOS volatile or nonvolatile quizlet?
The BIOS setup has also been called the “CMOS setup” or “CMOS RAM,” because settings were initially held in a battery-backed CMOS memory circuit. Subsequently, BIOS settings were stored in non-volatile flash memory. this is the type of battery that will power the CMOS when the PC is not plugged in.
Is DRAM memory volatile or nonvolatile?
DRAM is a volatile memory and retains data only as long as there is power supplied. The basic building block for DRAMs are the bit cells that store individual bits of information.
Which memory is non-volatile?
Examples of non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.
Is eeprom memory volatile or nonvolatile?
There is no clear boundary dividing the two, but the term “EEPROM” is generally used to describe non-volatile memory with small erase blocks (as small as one byte) and a long lifetime (typically 1,000,000 cycles).
Is SRAM volatile or nonvolatile?
Static random access memory (SRAM) loses its content when powered down, and is classified as volatile memory. The memory is volatile because there is no data when power is restored to the device. Another example of volatile memory is the dynamic random access memory (DRAM) used in all desktop computers and laptops.
What type of storage is a full length movie?
Data storage of DVD (digital versatile disc) is high when compare with CD. The storage capacity of a DVD is 4.7 GB (4,700 MB). To store a full length feature movie, it is better to store the movie by using DVD.
Is main memory volatile?
The primary memory is most volatile which means data in primary memory does not exist if it is not saved when a power failure occurs. The primary memory is a semiconductor memory. It is costlier compared with secondary memory.
Is ROM volatile memory?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
What are examples of volatile memory?
Below are some examples of volatile memory:
- System RAM (DRAM)
- Video RAM (VRAM)
- Processor L1 and L2 cache.
- HDD and SSD disk cache.

Where is non volatile memory stored?
Non-volatile memory typically refers to storage in semiconductor memory chips, which store data in floating-gate memory cells consisting of floating-gate MOSFETs (metal–oxide–semiconductor field-effect transistors), including flash memory storage such as NAND flash and solid-state drives (SSD), and ROM chips such as …
Why RAM is a volatile memory?
Volatile memory is computer storage that only maintains its data while the device is powered. … However, the data in RAM stays there only while the computer is running; when the computer is shut off, RAM loses its data. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost.
Where is volatile data stored?
Volatile data is mainly the only time a person will write data, and examples include hard disks and removable media. Dynamic random access memory (DRAM) and static random access memory (SRAM) are two places where volatile data will be stored.
What type of memory is DRAM?
There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM). DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory.
What type of memory is BIOS?
BIOS software is stored on a non-volatile ROM chip on the motherboard. … In modern computer systems, the BIOS contents are stored on a flash memory chip so that the contents can be rewritten without removing the chip from the motherboard.
Which type of memory is eeprom?
EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified.
