image uses 18 bits to represent a pixel. Compute the maximum number of different colors that can be represented? 2. For n devices in a network, determine the number of cable links required for a mesh, ring, bus, and star topologies? 3. Color pictures are to be downloaded at the rate of 900 pictures per minute. Compute the required bit rate of the channel. Assume each picture consists of 768 (height) x 1280 (width) color pixels. Each color pixel value is specified by 24 bits. 4. The loss in a cable is usually defined in decibels per kilometer (dB/km). If the signal at the beginning of a cable with - 0.5 dB/km has a power of 24 mW, determine the power of the signal at 18 km?
