Computer software can be divided into two main categories: application software and system software. Application Software: Application Software includes programs that do real work for user. Example: Payroll systems‚ Inventory Control‚ Manage student database‚ Word Processor‚ Spreadsheet and Database Management System etc. Application software consists of the programs for performing tasks particular to the machine’s utilization. Examples of application software include spreadsheets‚ database systems

probabilistic approach to finding failure-causing inputs based on Bayesian estimation. According to our probabilistic insights of software testing‚ the test case generation algorithms are developed by Markov chain Mote Carlo (MCMC) methods. Dissimilar to existing random testing schemes such as adaptive random testing‚ our approach can also utilize the prior knowledge on software testing. In experiments‚ we compare effectiveness of our MCMC-based random testing with both ordinary random testing and adaptive

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

Circuit Switching: | Packet Switching: | 1.) In circuit switching‚ there are various nodes used in the network through which the signals are passed from one system to another. 2.) In this a number of nodes are available between two devices and hence multiple paths are available to pass a signal. 3.)

APPLICATION SOFTWARE- is all the computer software that causes a computer to perform useful tasks (compare with computer viruses) beyond the running of the computer itself. A. Programming Language-is an artificial language designed to communicate instructions to a machine‚ particularly computer. Programming languages can be used to create programs that control the behavior of a machine and/or to express algorithms precisely.
