SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin

Introduction Network architecture is a combination of topology and protocols. In this paper‚ I will discuss topology‚ which is the defined as the shape of a network or how a network is laid out. Topology also consists of how the different components or nodes of a network are connected and how they communicate with each other. Topologies are either logical or physical. In addition‚ in the sections of this paper‚ I will compare and contrast some different conventional architecture and what types of topologies
