The Unified Software Development Process Framework

Reflections of chapter 1, 2 and 3: Chapter 1: Computer Technology: Your Need to Know Unified Process: The Unified Software Development Process is a popular iterative and incremental software development process framework. Fig.1.1 – Disciplines and phases in the Unified Process Phases under Unified process: 1) The Inception phase: It basically focuses on establishing the project s scope and vision. 2) The Elaboration phase: It focuses on establishing the system s requirements and architecture. 3) The Construction phase: It focuses on completing construction or building of the system. 4) The Transition phase: It focuses on completing transitioning or deployment of the system to the user community. Disciplines under Unified Process:†¦show more content†¦Ã¢â‚¬ ¢ The testing discipline includes activities that verify correct functioning of infrastructure and application software components. 4) Deployment Disciplines: †¢ The deployment discipline contains set of activities for installing and configuring infrastructure and application software components and bringing them into operation. †¢ Technical knowledge of computer hardware and system software is needed to perform deployment tasks. Chapter 2: Introduction to System architecture Computer system classes: Computer systems are classified on the basis of CPU, storage capacity, I/O capacity, and number of users simultaneously using a system, and an application software. Classes of computer systems: †¢ Microcomputer †¢ Portable †¢ Midrange computer †¢ Mainframe †¢ Supercomputer 1) Microcomputer: †¢ It is a small sized relatively cheap computer with a microprocessor and a CPU. †¢ It can also be known as a Personal computer or a workstation. †¢ It is a computer with less capacity and capability less than a minicomputer. †¢ Specially in the 1970s and 80s with the advent microcomputers became popular in the 1970s and 80s †¢ Computer memory is in the form RAM. †¢ Workstation is more powerful than a personal computer which can be specifically used for scientific purpose. 2) Portable: †¢ Portable computer is cheaper than a microcontroller as the components used are reduced in size and also a technology of a battery is improved. †¢ Again there are different types of
