Changes to the design included a matte black HDD cover replacing the original gloss black version.
What are the differences between Primary and Secondary Memory? Both these memories vary in the speed, cost and capacity. Primary memory is considered as a main memory that is accessed directly by the computer, so as to store and retrieve information.
Secondary memory is considered as an external or additional memory, this memory is not directly accessed by the CPU because, the secondary memory is an external storage device, It can be used as a permanent memory, because even the computer is turned off we can retrieve the information.
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 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.
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.
The following table list out some of the key differences between the primary and secondary memory: Primary memory The memory devices used for primary memory are semiconductor memories The secondary memory devices are magnetic and optical memories.
Primary memory is known as main memory Secondary memory is known as additional memory or back memory These memories are also called as internal memory These memories are also called as external memory Primary memory is temporary The secondary memory is permanent Commonly used primary memory main memory available in the range of MB to 8 GB RAMs.“Secondary storage” is a generic term that means storage not part of main memory/” RAM”.
It might be disk, an SD card, magnetic tape, punched cards, etc, etc. ROM indicates a memory device that can be read from, but not written to.
To rope in more and more mobile lovers, Smartphone manufacturers are trying frantically to add extra CPU cores and RAM to their new phones. There was a time when there were only numbered smartphones with 3GB RAM, but at present it seems to have come a deluge of Android devices boasting 3GB RAM.

Difference Between RAM and ROM February 7, Posted by Kasun RAM (Random Access Memory) is a fast accessible memory that stores data during its operation while ROM (Read Only Memory) stores permanent data that is used for its functions, such as the information for booting the computer.
