what is difference between primary key and secondary key
you suck yousuck!
primary memory is RAM, ram is volatile and is used to store information while it is being processed. secondary memory is basically hard drive space that is permanent. volatile memery is lost when power is disconnected
primary memory stores the necessary programmes or system software which are required to execute application programs while secondary memory is needed to bulk storage of programs and data .
Primary Memory is connected with the motherboard. Examples of primary memory are RAM, ROM, PROM, etc. it works very fast. Secondary Memory are those which are connected to the computer from outside. Examples of secondary memory are floppy disk, cd's, DVDs, etc.
They are both storage devices
primary memory consist of RAMsecondary memory consist of ROM
Cache memory is smaller and quicker, primary memory larger and slower.

Primary memory vs Secondary memory Processor access the primary memory in a random fashion. Unlike primary memory, secondary memory is not directly accessed through CPU. The accessing of the primary memory through CPU is done by making use of address and data buses, whereas input/ output channels are used to access the secondary memory. The primary memory is embedded with two types of memory technologies; they are the RAM (Random Access Memory) and ROM (Read Only Memory). The secondary memory is accessible in the form of Mass storage devices such as hard disk, memory chips, Pen drive, floppy disk storage media, CD and DVD. Primary memory is volatile in nature, while secondary memory is non volatile. The information that is stored in the primary memory cannot be retained when the power is turned off. In case of secondary memory, the information can be retrieved even if the power is turned off because the data will not be destructed until and unless the user erases it. When the data processing speed is compared between the primary and secondary memory, the primary memory is much faster than the secondary memory. In the cost perspective, the primary memory is costlier than the secondary memory devices. Because of this reasons most of the computer users install smaller primary memory and larger secondary memory. As the secondary memory is permanent, all the files and programs are stored in the secondary memory most and as the primary memory interacts very fast with the micro processor, when the computer needs to access the files that are stored in the secondary memory, then such files are first loaded into the primary memory and then accessed by the computer.
Primary storage in a device is the place where all data is preferably stored by default. Although if it is found to be full , the data gets stored in the secondary storage memory.
No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.
Secondary memory provides more storage space compare to primary memory.
Intenal memory is only primary memory. The term secondary memory is used for External storage like hard disk etc.
"Describe different types of primary and secondary memory of a computer?
You have to keep on remebering the memory
primary memory & secondary memory
Usually the hard drives are considered secondary. The RAM (Random Access Memory) is the primary memory.
The computer uses microchips for primary and secondary memory. Virtual memory uses a portion of the computers hard drive. The former have faster access times than the latter.
If my memory serves me well its less than 2.0 ohms for the primary and between 10,000 -11,000 ohms for the secondary, Mike
primary memory-he is called primary memory because this is the internal memory of CPU .This memory tempararey scope for data.this memory is called vallatile memory because when the power swiched off store data is finished.This memory relatively fast for primary memory
