3.1. Pipes and Filters In a pipe and filter style each component has a set of inputs and a set of outputs. A component reads streams of data on its inputs and produces streams of data on its outputs‚ delivering a complete instance of the result in a standard order. This is usually accomplished by applying a local transformation to the input streams and computing incrementally so output begins before input is consumed. Hence components are termed “filters”. The connectors of this style serve

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

The Software Crisis • The most visible symptoms of the software crisis are o Late delivery‚ over budget o Product does not meet specified requirements o Inadequate documentation • Some observations on the software crisis o “A malady that has carried on this long must be called normal” (Booch‚ p. 8) o Software system requirements are moving targets o There may not be enough good developers around to create all the new software that users need o A significant portion of developers’ time must often

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

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. Definition of programming language * The description of a programming

Identifying and comparing the main components of blood. By Jason T Morrison. Blood‚ what an amazing substance. It has only been since being set this task by one of my tutors‚ Dr C Dublon that I have truly realised how amazing blood really is. Blood is not as some people may think just made up of one component‚ but many different components working together in an almost symbiotic relationship. The average human being carries approximately five litres of blood‚ which is equivalent to about
