What are the disadvantage of primary storage?

Answer 1

Well for mac you can only back up your data when you have a secondary storage hard drive, for windows it gives you more space to download and to use it, basic

Answer 2

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.

Answer 3

It is very fast to access and can be sent directly to the CPU. the only disadvantage is that storage is small and temporary.

Answer 4

Stores less data
