(a) Core memory
(b) Virtual memory
(c) RAM
(d) Dynamic memory
(e) None of the above
Ans.(b)
Sol. Virtual Memory is the memory that appears to exist as main storage although most of it is supported by data held in secondary storage, transfer between the two being made automatically as required.

(a) 1617
(b) 1801
(c) 1824
(d) 1901
(e) 1917
Ans.(a)
Sol. In 1617 a treatise in Latin titled Rabdologiae and written by John Napier was published in Edinburgh. Printed three years after his treatise on the discovery of logarithms and in the same year as his death, it describes three devices to aid arithmetic calculations.The devices themselves don't use logarithms, rather they are tools to reduce multiplication and division of natural numbers to simple addition and subtraction operations.
