Suppose you were told that the horizontal resolution of a digital photograph taken is stored as a 16bit number at offset 434. Suppose you were told that the file format dictates big endian ordering. What is the horizontal resolution of the digital photograph in hex and decimal?Again, suppose you were told that the horizontal resolution of a digital photograph taken is stored as a 16bit number at offset 434. But this time, suppose you were told that the processor is Intel x86 and that the file format does not “trump” the normal little endian ordering that would then be presumed. What is the horizontal resolution of the digital photograph in hex and decimal?What if you were told that the horizontal resolution is stored as a 32bit number, presuming big endian ordering? What is the resolution in hex and decimal?What if you were told that the horizontal resolution is stored as a 32bit number, presuming little endian ordering? What is the resolution in hex and decimal?Answer the following questions considering the MBR shown in Figure 2.Recreate and fill-in the following table:Partiton

b. What would you do to calculate the size of each partition in bytes?

c. Estimate how big this hard drive is (i.e. 80GB, 100GB, 160GB, etc).

d. What does the line shown separating “row 496” and “row 512” represent?
