The memory units that follow are specified by the number of words times

the number of bits per word. For each of the following cases, determine $($i$)$ How many

address lines and input$-$output data lines are needed in each case; and $($ii$)$ How many bytes

are needed in each case. $($a$)32K**16$; $($b$)3G^{**}8$; $($c$)7M**32$; $($d$)256**64$

I want the solution especially for point $($b$)$ and $($c$)$
