What is Memory ?

A place where we can store the data or set of instructions to access them while performing the operations.

There are two types of memories :-

1. RAM (Random Access Memory)

2. ROM (Read Only Memory)

1. RAM : - Random access memory one of the storage devices which performs read and write both operations. But RAM is volatile in nature it losses the data when there is no power supply. It is fast when programming when compare to ROM.

There are two types of RAM : -

1. DRAM (Dynamic Random Access Memory)
2. SRAM (Static Random Access Memory)

ROM (Read Only Memory) : -

Main  advantage of ROM is that we can easily altering data or re-programmable . Advantage of ROM is it is non-volatile in nature which does not losses any data when there is no power supply. Motherboard my consist of more than one ROM chips.

Types of ROM : -

1. ROM - Read Only Memory
2. PROM - Programmable Read Only Memory
3. EPROM - Erasable Programmable Read Only Memory
4. EEPROM - Electrically Erasable Programmable Read Only Memory
5. Flash EEPROM memory
