Primary Memory.
1.RAM: Random Access Memory(RAM) is a memory scheme within the computer
system responsible for storing data on a temporary basis, so that it can be promptly
accessed by the processor as and when needed.
RAM stores data randomly and the processor accesses these data randomly from the RAM storage.
2. ROM (Read Only Memory): ROM is a permanent form of storage. ROM stays
active regardless of whether power supply to it is turned on or off.
Secondary Memory:
1. HARD DRIVE(HD): A hard disk is part of a unit, often called a "disk drive," "hard drive," or"hard
disk drive," that store and provides relatively quick access to large amounts of data on an
electromagnetically charged surface or set of surfaces..
2. Optical Disk: an optical disc drive (ODD) is a disk drive that uses laser light as part of the process
of reading or writing data to or from optical discs. Some drives can only read from discs, but recent
drives are commonly both readers and recorders, also called burners or writers. Compact discs,
DVDs, and Blu-ray discs are common types of optical media which can be read & recorded
such drives.
3. Flash Disk:- A storage module made of flash memory chips. A Flash disks have no mechanical platters or access
arms, but the term "disk" is used because the data are accessed as if they were on a harddrive. The
disk storage structure is emulated.
