A sparse matrix contains many (often mostly) zero entries. The basic idea when storing sparse matrices is to only store the non-zero entries as opposed to storing all entries. Depending on the number and distribution of the non-zero entries, different data structures can be used and yield huge savings in memory when compared to a naïve approach. One example of such a sparse matrix format is the (old) Yale Sparse Matrix Format [1]. It stores an initial sparse N×N matrix M in row form using three arrays, A, IA, JA. NZ denotes the number of nonzero entries in matrix M. The array Athen is of length NZ and holds all nonzero entries of M. The array IA stores at IA(i) the position of the first element of row i in the sparse array A. The length of row i is determined by IA(i+1) - IA(i). Therefore IA needs to be of length N + 1. In array JA, the column index of the element A(j) is stored. JA is of length NZ. Another possibility is to use quadtrees
Memory.
memory
Memory cache stores frequently used instructions and data on a computer. Cache memory is stored on a memory chip in an area of the RAM.
MAR-memory address register used stored the address of the memory loaction MBR- memory buffer register is the actully data.
Permanant information is stored in hard drives, usb drives, cds, dvds and the temporary information is stored in RAM (Random Access Memory).
Computer memory
Computer memory is what data the computer can keep stored. A computer can return to your favorite web address because it is stored in it's memory for example.
Memory.
The memory in the computer is stored in the form of bits and bytes
Where data can be stored.
a program that is stored in the memory of the computer that executes it

non volatile memory is the computer memory that can retain stored information when not powered . examples flash memory . read only memory.(F) ram.volatile memory is the computer memory that requires power to maintain stored information in other words it need power to reach the computer memory volatile memory retain the information as long as the power supply is on .
