Which is secondary memory RAM or ROM?

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 class 5 secondary memory?

With respect to class 5 Computer Memory, secondary memory is used to permanently store user-programs, as well as raw and processed data. Both the process and data can then be repeatedly used whenever required. For example floppy disk, hard disk, compact disk. Secondary memory is used to store data permanently.

What is secondary memory in psychology?

secondary memory (SM)

memory that retains a large number of items relatively permanently, in contrast to primary memory. The term was used in dual-store models of memory before being replaced by long-term memory. [ introduced by William James ]

What are the main characteristics of secondary memory?

Characteristics of Secondary Memory

• These are magnetic and optical memories.
• It is known as the backup memory.
• It is a non-volatile memory.
• Data is permanently stored even if power is switched off.
• It is used for storage of data in a computer.
• Computer may run without the secondary memory.
• Slower than primary memories.

What is need for secondary memory?

Secondary storage therefore needed because it is non-volatile, meaning it retains its contents without the need for a power supply. It also has the large storage capacity needed to store the operating system and all the programs and files needed by a modern computer system.

Is an example of secondary memory?

Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. ... For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM.

What is difference between primary memory and secondary memory?

KEY DIFFERENCE

Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor. ... Primary memory is both volatile & nonvolatile whereas Secondary memory is always a non-volatile memory.

What is main memory and secondary memory?

The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept.

What are some examples of secondary storage device?

Examples of secondary storage media include recordable CDs and DVDs, floppy disks, and removable disks, such as Zip disks and Jaz disks. Each one of these types of media must be inserted into the appropriate drive in order to be read by the computer.
