sequential access memory การใช้

• While sequential access memory is read in sequence, arbitrary locations can still be accessed by " seeking " to the requested location.
• Magnetic storage media can be classified as either sequential access memory or random access memory, although in some cases the distinction is not perfectly clear.
• Magnetic sequential access memory is typically used for secondary storage in general-purpose computers due to their higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility.
• This made manual multiplication easier, as one needed to follow two parallel columns ( instead of a vertical column and a horizontal row in the matrix notation . ) It also sped up computer calculations, because both factors'elements were used in a similar order, which was more compatible with the sequential access memory in computers of those times  mostly magnetic tape memory and drum memory.
