Context for Item 1: If a textbook page is scanned, converted to PDF, and fitted to a standard 8.511-inch page for printing, the page image would be a pikel (picture element) array that is 816 pixels wide and 1056 pixels high this is a total of 861,696 pixels per page: 1) 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 textbook's 450 pages over a T-1 connection at 1.544Mbps(1,544,000 bps)? e. How long would it take (in seconds) to transmit a PDF file of the textbook's 450 pages over an OC-3 fiber optic circuit at 155.52Mbps(155,520,000 bps)? f. How long would it take (in seconds) to transmit a PDF file of the textbook's 450 pages over a 500 Mbps (500,000,000 bps) Cartier Ethernet circuit? B. How long (in seconds) would it take to transmit a por file of the textbooks 450 pages in a a 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 PoF mage 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
