Computer Fundamentals 6512. A certain memory is specified as 32K × 8. Determine (a) the number of address input lines, (b) thenumber of data input lines, (c) the number of data output lines and (d) the type of decoder.(a) 15; (b) 8; (c) 8; (d) 1-of-15 decoder3. It is desired to construct a 64K × 16 RAM from an available RAM chip specified as 16K × 8.Determine the number of RAM chips required for the same.84. The following data refer to a hard disk: number of tracks per side = 600; number of sides = 2;number of bytes per sector = 512; storage capacity in bytes = 21 504 000. Determine the numberof sectors per track for this hard disk.35Further Reading1. Tocci, R. J. and Ambrosio, F. J.
