What is secondary memory and types?
Secondary memory is called also Backup or Auxiliary memory . Primary memory has two categories like as RAM and ROM. Secondary memory has four categories like as Magnetic Storage, Optical Storage, Flash storage, and Online Cloud System. Primary memory is more costly to secondary memory.
What are the primary and secondary storage devices?
Primary memory usually refers to Random Access Memory (RAM) , while secondary storage refers to devices such as hard disk drives, solid state drives, removable “USB” drives, CDs, and DVDs.
Is ROM a secondary storage device?
Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory( hard drive ,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.
What is difference between primary and secondary memory?
Primary memory is directly accessible by Processor/CPU. Secondary memory is not directly accessible by the CPU. ... The memory devices used for primary memory are semiconductor memories. The secondary memory devices are magnetic and optical memories.
What is advantage of secondary memory?
Moving infrequently used data to secondary storage immediately lowers costs since secondary storage comes in higher capacities and is less expensive than primary storage. This is important if you are using secondary storage for backup purposes which requires having large amounts of storage capacity for duplicated data.
