Because tapes are best read in a forward motion.
To access a tape randomly would be extremely slow. You would have to continually rewind and check if the data was the reverse of what you were looking for.
It is very impractical and slow.
Tapes are good for storing large amounts of data cheaply and securely. (IE, smaller risk of failure, low cost per TB, easy to store in a bank vault or warehouse.)
Random Access Memory, as verses Sequential Access Memory (delay lines, magnetic tape, magnetic drum, magnetic disk, etc.)
Advantages: One of the cheapest forms of data storage. Disadvantage: low density (bulky), not random access (slow).
Sequential access memory. Typically implemented with long shift registers, acoustic delay lines, or fixed head magnetic drums/disks.
Yes, or at least Mostly Yes. RAM is random (RAM=Random Access Memory) and most forms of RAM today are volatile. But magnetic core memory (from the 1950s, now only available in museums) is not.
random access memory
RAM is for Random Access Memory and it is used as sort of a temporary data holding place for the CPU (Central Processing Unit). It holds the code of the program you are running and data being processed.
I think the answer you're looking for is disk storage... But I'm not positive!
