Unit 1. Lab 1. Fixed Line vs. Cellular Debate A cellular network or mobile network is a wireless network distributed over land areas called cells‚ each served by at least one fixed-location transceivers known as a cell site or base station. In a cellular network‚ each cell uses a different set of frequencies from neighboring cells‚ to avoid interference and provide guaranteed bandwidth with each cell. When joined together these cells provide radio coverage over a wide geographic area. This enables

The first category of faults flips random bits in random instructions of the program text to emulate hardware faults. These faults are easy to inject‚ and they cause a variety of different crashes. It is difficult to relate a bit flip with a specific error in programming‚ and most hardware bit flips would be caught by parity on the data or address bus. The next two faults categories‚ excluding the OMISSION faults‚ emulate specific programming errors common to kernel code according to earlier studies
