The document discusses different types of computer memory. There are two main types: primary and secondary memory. Primary memory, also called main memory, is volatile and holds data temporarily, including RAM and ROM. RAM is further divided into SRAM and DRAM. ROM is non-volatile and includes PROM, EPROM, and EEPROM. Secondary memory is non-volatile external storage used to permanently store data, and is slower than primary memory.

- 3. Primary Memory It also known as Main memory. Usually volatile in nature. Hold or store data and application temporarily. Data is lost in case of power failure or power turn off. Faster than secondary memory It is of two types : a)ROM b)RAM
- 4. RAM(Random Access Memory) A RAM memory chip is an Integrated circuit made of millions of transistors and capacitors. Volatile in nature. It consists of : S RAM (Static RAM) D RAM (Dynamic RAM) http://www.wifinotes.com/computer-networks1/types-of-computer- memory.jpg
- 5. ROM(Read Only Memory) http://4.bp.blogspot.com/_4VViu-- CS_c/SwJjKKQzY8I/AAAAAAAAAAM/wmiLgfam This is a memory from which we can only read but cannot write Non-volatile in nature. Cheaper than RAMs. It consists of: PROM EPROM EEPROM
- 6. Secondary Memory It is known as External Memory. Non-volatile in nature. It is used to store data permanently in the computer. Slower than primary memory. http://touque.ca/EC/students/LiM /Definition_Images/secondary_sto rage.jpg
