what are the difference between primary and secondary storage?

Difference between Primary storage and secondary storage. Primary memory is the main memory (Hard disk, RAM) where the operating system resides. Secondary memory can be external devices like CD, floppy magnetic discs etc. secondary storage cannot be directly accessed by the CPU and is also external memory storage.

Thus, when a processor requests data that already has an instance in the cache memory, it does not need to go to the main memory or the hard disk to fetch the data. Cache memory can be primary or secondary cache memory, with primary cache memory directly integrated into (or closest to) the processor.

That's called volatile memory. ... The difference in them are that RAM is primary memory and ROM and Hard drive is secondary memory. RAM is also called temporary memory because data it stores data for less time or temporarily while ROM and Hard drive stores permanently although we can delete the data from ROM.

['"Primary memory" is the memory which is much quicker and has higher access speed in comparison to the secondary memory. ... ', 'After cache memory, the primary memory has the highest access speed of all other types of memory devices.']

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.

Computer data storage devices are also classified by their distance from the processor, or CPU. The closest storage is memory, or RAM. This is the only kind of data storage that directly accesses the CPU. ... For most personal computers, secondary storage is the main data storage device.

However, the Random Access Memory (RAM) is a temporary storage while the hard drive is the permanent computer storage, it lets you store data for a very long time, and its capacity is measured in Terabytes (TB) or Gigabytes (GB).

The main advantage of primary data is that they will answer a specific research question that secondary data cannot answer. Primary data are current and the source of data is known. Moreover, the information is proprietary. Primary data can be very expensive.

The difference between primary and secondary data in Statistics is that Primary data is collected firsthand by a researcher (organization, person, authority, agency or party etc) through experiments, surveys, questionnaires, focus groups, conducting interviews and taking (required) measurements, while the secondary ...

Primary data is the type of data that is collected by researchers directly from main sources while secondary data is the data that has already been collected through primary sources and made readily available for researchers to use for their own research.

It must first be copied into primary storage (also known as RAM). Secondary memory devices include magnetic disks like hard drives and floppy disks ; optical disks such as CDs and CDROMs ; and magnetic tapes, which were the first forms of secondary memory.

Primary data is a real-time data whereas secondary data is one which relates to the past. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand. Primary data collection is a very involved process.

primary - information that you collect yourself, eg tallies, measurements and photographs. secondary - information that someone else has previously collected and made available, eg on the internet.

The Difference Between Memory and Storage. Your computer's main memory is called RAM. You can think of it as a workspace the computer uses to get work done. ... There's also storage: a hard disk drive or solid state drive where data is recorded and can stay indefinitely, to be recalled as necessary.

Computers have two kinds of storage — temporary and permanent. A computer's memory is used for temporary storage, while a computer's hard drive is used for permanent storage. ... A computer's memory is where information is temporarily stored while it is being accessed or worked on.

Internal and External Memory Internal memory is normally associated with RAM (Random Access Memory) and is also known as main memory. It is typically smaller in size but has faster access times. External memory, also known as secondary memory, is separate from main memory.
