The hard disk sometimes called the “hard drive” (which is actually the mechanism that holds the hard disk), is a spindle of magnetic discs that can hold several gigabytes of data. ... Memory, on the other hand, is not the same as disk space! Memory refers to the random access memory (RAM) inside your computer.

Answer: Physical memory is how much RAM you have installed in your computer. For example, if you have two 512 MB memory chips in your machine, you have a total of 1 GB of physical memory. ... Available memory refers to how much RAM is not already being used by the computer.

A computer's memory is used for temporary storage, while a computer's hard drive is used for permanent storage. Whoever selected the term memory for temporary computer storage did the world a disservice since people tend to permanently store information in our memories.

Storage. Whereas memory refers to the location of short-term data, storage is the component of your computer that allows you to store and access data on a long-term basis. ... An important distinction between memory and storage is that the former clears when the computer is turned off.

RAM is volatile memory, meaning that when power is turned off, any information or data stored in RAM is lost forever, whereas the SSD uses non-volatile memory which retains the information or data stored on is even when it is powered off.

KEY DIFFERENCE Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor. Primary memory is costlier than secondary memory whereas Secondary memory is cheaper compared to primary memory.

Both RAM and hard drive memory are referred to as memory, which often causes confusion. RAM stands for Random Access Memory. Physically, it is a series of chips in your computer. ... Programs that are currently running, and open files, are stored in RAM; anything you are using is running in RAM somewhere.

Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD speed so much faster.

The term "drive" originally referred to the thing moving the storage media - like a floppy drive is something you put a floppy disk into and it spins it. A tape drive is the thing that drives the tape around the read-write heads. ... So a hard disk drive is referring to both the disk and the drive at the same time.

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 storage refers to the main storage of the computer or main memory which is the random access memory or RAM. Secondary storage, on the other hand, refers to the external storage devices used to store data on a long-term basis.

Memory cache is stored on RAM, which is faster to write and access, but will be wiped out when the computer turns off or in certain other situations. Disk cache is written to the hard drive, which is slower to read and write, but it will stay on the disk.

Difference between Primary and Secondary Memory While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.

SSD vs. HDD: What's the difference? A hard disk drive (HDD) is an old-school storage device that uses mechanical platters and a moving read/write head to access data. A solid-state drive (SSD) is a newer, faster type of device that stores data on instantly-accessible memory chips.
