DIGITAL COMMUNICATIONS I INTRODUCTION TO DIGITAL COMMUNICATIONS 1 A. A computer program collects data at a steady rate of 14.4 kbps. When the program is finished, the size of the data file is 1.44 MB. The program was collecting data for a period of the most nearly a) 2.0 min b) 10 min c) 13 min d) 14 min B. An 8 GB RAM module uses 32-bit words. A bidirectional bus transmits data from the memory module. Assuming whole words are read simultaneouslhy on the same bus cycle and disregarding parity bits, what width bus is needed to transmit data between the CPU and the memory module? b) 16 c) 32 d) 64 C. A 3.5 in hard drive is advertised as a 1.5 TB drive. It contains four two-sided platters. Each surface is formatted to have 718,357 tracks with 63 sectors per track. The fewest bytes used to store a file is most nearly a) 1024 B b) 4096 HB c) 5120 B d) 8192 B
