1. If a textbook page is scanned, converted to PDF, and fitted to a standard 8.5 x 11-inch page for printing, the page image would be a pixel (picture element) array that is 816 pixels wide and 1056 pixels high; this is a total of 861,696 pixels per page.

If eight (bits) are used to represent the color of each pixel:

a) How many different color levels can a single pixel represent?

b) If each pixel has an 8-bit color code, how many bits are needed to represent each page image?

c) If a data communications textbook has 450 pages, how many bits are needed to represent a PDF file that includes all 450 pages.

d) How long would it take (in seconds) to transmit a PDF file of the textbooks 450 pages over a T-1 connection at 1.544 Mbps (1,544,000 bps)?

e) How long would it take (in seconds) to transmit a PDF file of the textbooks 450 pages over an OC-3 fiber optic circuit at 155.52 Mbps (155,520,000 bps)?

f) How long would it take (in seconds) to transmit a PDF file of the textbooks 450 pages over a 500 Mbps (500,000,000 bps) Carrier Ethernet circuit?

g) How long (in seconds) would it take to transmit a PDF file of the textbooks 450 pages in a 1 Gbps Ethernet LAN?

h) True color images use 24-bits to represent the color of each pixel. What formula should be used to calculate the total number of bits needed to represent a single textbook page if the PDF image used True color pixels instead of 8-bit pixels? Assume that the pixel array remains 816 by 1056. You do not have to perform the calculation specified in your formula.
