What are the 4 characteristics of secondary storage?

Factors affecting the choice of a secondary storage device include:speed (how quickly data can be accessed)cost per storage unit (i.e. price per gigabyte or megabyte)durability (toughness)portability (how easy it is to move it from one computer to another)

What are primary and secondary devices?

A computer’s internal hard drive is often considered a primary storage device, while external hard drives and other external media are considered secondary storage devices. … In this case, primary storage typically refers to random access memory (RAM), while secondary storage refers to the computer’s internal hard drive.

What is an example of secondary storage?

Secondary storage is non-volatile , long-term storage. … solid state storage devices, such as USB memory sticks. optical storage devices, such as CD, DVD and Blu-ray discs. magnetic storage devices, such as hard disk drives.

What are the four types of secondary memory?

Secondary memory has four categories like as Magnetic Storage, Optical Storage, Flash storage, and Online Cloud System.

What is difference between primary 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 costlier than secondary memory whereas Secondary memory is cheaper compared to primary memory.

What is primary storage and secondary storage?

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. …

What are 2 types of primary storage?

Primary storage (also known as main memory ) is the component of the computer that holds data , programs and instructions that are currently in use.Primary storage is located on the motherboard . … The two main types of primary storage are ROM, which is non-volatile , and RAM, which is volatile .More items…

Is prom a primary storage device?

Examples of Primary Storage ROM: Unlike RAM, Read Only Memory (ROM) is both a non-volatile and permanent form of primary storage. … PROM: Programmable Read Only Memory is an advanced form of ROM that will allow writing data – but only once. Similar to a blank CD or DVD, PROM does not comes with data stored on the chip.

What is an example of primary storage?

A primary storage device is a medium that holds memory for short periods of time while a computer is running. … RAM (random access memory) and cache are both examples of a primary storage device.

What is secondary storage?

Secondary storage is non-volatile , long-term storage. It is used to keep programs and data indefinitely. Without secondary storage all programs and data would be lost the moment the computer is switched off.

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.

Is ROM a secondary memory?

ROM is a type of non-volatile memory, which means that the data stored in ROM persists in the memory even when it receives no power – for example when the computer is turned off. In that sense it is similar to secondary memory, which is used for long term storage.

What is the other name of secondary memory?

Also called auxiliary storage, auxiliary memory, external storage, secondary memory .

What are the main characteristics of secondary memory?

Characteristics of Secondary MemoryThese 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.
