1. Suppose a machine has 20GB of storage space available on a hard disk and receives data over a telephone connection at the rate of 14,400 bps. At this rate, how long would it take to fill the available storage space?
2. Suppose a picture is represented on a monitor screen by a rectangular array containing 1024 columns and 768 rows of pixels. If eight bits are required to code the color and intensity of each pixel, how many byte-size memory cells are required to hold the entire picture?
3. How many cells can be in a computer's main memory if each cell's address can be represented by three hexadecimal digits?© BrainMass Inc. brainmass.com October 9, 2019, 3:57 pm ad1c9bdddf
1) Rate of reception = 14,400 bits/sec
8 bits = 1 Byte, hence
14400/8 = 1800 B / sec
1800 B in ------ 1 Sec
20 * 10^9 * 8 bits in ----? sec
(20 * 10^9 * 8) / 1800 ...
The solution determines the data communication rate.
