Secondary memory, also called auxiliary memory or mass storage, consists of devices not directly accessible by the CPU. Hard drives, floppy disks, tapes, and optical disks are widely used for secondary storage. The input and output of these devices is much slower than for the semiconductor devices that provide the computer's primary memory. Although access times (i.e., the time to read or write information) are slow as compared to that of primary memory, secondary memory devices have important features that are unmatched by primary memory. First, most secondary storage devices are capable of containing much more information than is feasible for primary memory (hence the use of the term "mass storage" as a synonym for secondary memory). A second, and essential, feature of secondary memory is that it is non-volatile. This means that data is stored with or without electrical power being supplied to the device, as opposed to RAM, which can retain its data only so long as electrical power is present.
It is a removable disk and a USB drive.
name one access secondary device?
To determine the memory size of a device, you can calculate it by multiplying the number of memory cells by the size of each memory cell. This will give you the total memory size of the device.
no prom is primary device
Memory slot is a place where a memory can introduced to a system. It is an interface to add a memory device. This can be various types. For introduce primary memory we use tha RAM slot. Or for secondary memory interfacing we use different types of interfacing, such as PATA, SATA etc. But for RAM interfacing we require to match FSB (BUS Speed) of the memory device, such as FSB 400 or 667 or 800 etc. External chache is noting but a chache memory that is attached to a computer system to optimise its performance. It is used to boost up the performance of a conventional computers.
Long term memory is found on secondary storage devices.
It is a removable disk and a USB drive.
Read only memory
FLASH MEMORY is used in cell phones.
Secondary Storage in a computer is memory device other than primary memory like disk ,floopy, usb ports etc. they are used to store data for future use.
hard drive, it is also the storage device or database and also the secondary memory of computer
ram is primary storage
Random Access memory
Secondary storage device is USB and also the external hard disk are external devices these are best for external memory.
The Loader is a program that moves the executable file produced by linker from the secondary storage device to memory for execution
size range of secondary memory
Secondary Memory-: is long term storage device which uses the help of input and output channels to access information.The content in it must first be copied into the primary storage (RAM) for CPU to process . It does not lose the data when device is powered off .It is nonvolatile.Eg: Hard Disk(HD),Floppy ,CD.Its Ram-random access memory to the device 3.5 &5.7 .
