For the I/O device to get 512 words when the I/O device uses 4 as the word count. (512 words is 2048 bytes) a) Compute the total time from after receipt of the address to the end of the last transaction. b) Compute the transactions per second. c) Compute the bandwidth. For the I/O device to get 512 words when the I/O device uses 32 as the word count. d) Compute the total time from after receipt of the address to the end of the last transaction. e) Compute the transactions per second. f) Compute the bandwidth.

Are special characters that allow you to search for multiple words at the same time.

Write a program which asks you to enter a name in the form of first middle initial last. so you might enter for example samuel p. clemens. use getline to read in the string because it contains spaces. also, apparently the shift key on your keyboard doesn’t work, because you enter it all lower case. pass the string to a function which uses .find to locate the letters which need to be upper case and use toupper to convert those characters to uppercase. the revised string should then be returned to main in the form last, first mi where it will be displayed.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
