3. WHAT IS STORAGE & MEMORY ? STROAGE Provide capacity for all the files and information. MEMORY provide working space.

4. OVERVIEW Primary Necessary to run the computer. storage of intermediate data. Ram cache secondary Long term storage of data. HDD Tertiary Cd DVD memory card.

5. MAIN MEMORY TWO TYEPS RAM Main memory is sometimes called  RAM.  RAM stands for  Random Access Memory . “ Random means that memory cell can be accessed any orer . Rom Rom is read only memory.

6. The following are two common types of RAM: SRAM : Static random access memory uses multiple transistors, typically four to six, for each memory cell but doesn't have a capacitor in each cell. It is used primarily for  cache . DRAM :  Dynamic random access memory  has memory cells with a paired transistor and  capacitor  requiring constant refreshing. Also fpm dram , edo d ram, cmos ram, vram . Rom P rom E rom Ep rom

7. Cache memory Cache memory, also called CPU memory, is random access memory ( RAM ) that a computer  microprocessor  can access more quickly than it can access regular RAM. This  memory  is typically integrated directly with the  CPU  chip or placed on a separate  chip that has a separate  bus  interconnect with the cpu .
