what is difference between primary key and secondary key
primary memory consist of RAMsecondary memory consist of ROM
Intenal memory is only primary memory. The term secondary memory is used for External storage like hard disk etc.
No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.
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.
Secondary memory provides more storage space compare to primary memory.
"Describe different types of primary and secondary memory of a computer?
primary memory & secondary memory
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.
You have to keep on remebering the memory
primary memory secondary memory cache 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.
primary and secondary
Addresses of virtual memory is found in descriptor table lies in primary memory but the content of the page is stored in secondary memory.
The primary memory or primary storage refers to the RAM - Random Access Memory and the CPU Memory. Secondary memory refers to the hard disk.
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
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 .
They are both storage devices
For new computers it can be both.
two types of memory i.e. primary and secondary memory.
