Software development life cycle
The software development life cycle is also known as software development performance. SDLC is a structure which is compulsory for development of software products.

Unified Process
It is a popular iterative and incremental software development process framework. The best-known and extensively documented refinement of the Unified Process. Unified process can be applied to different software organizations with different degrees of technical and managerial complexity across various areas and organizational cultures. UP is also referred to as the unified software development process.
• The Business Modeling discipline focuses on understanding business being automated by the system and capturing such knowledge in a Business model.
• The Requirements discipline focuses on understanding the requisites of the system that automates the business and capturing such knowledge in a Use-case example.
• The Analysis & Design discipline focuses on wearing down the requirements and planning the system and capturing such knowledge in an Analysis/Design model.
• The Implementation discipline focuses on enforcing the scheme grounded in the Implementation model.
• The Test discipline focuses on testing the system against the requirements based on the Test model.
• The Deployment discipline focuses on deploying the system based on the Deployment model.

... middle of paper ..., are represented in modern computers as strings of binary digits, or bits. Bits are used because 0 and 1 can be encoded in clearly recognizable electrical states, such as high and low voltage. A handful of primitive data types is represented and treated by a CPU, including integers, real numbers, types, Boolean values, and memory addresses.

In conclusion, the exploration of the different ways data is represented in modern computers, focusing particularly on the relationship between data representation and the CPU. The introduction of basic concepts and terminology of systems architecture and the understanding of the same helps in the foundation for the in depth knowledge of the hardware implementations of data processing, storage, and communication.

System Development Life Cycle Essay

- Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1). The first phase in SDLC is planning. In this phase, the potential system development project is identified. Project manager summarizes all strength and weakness that possible to occur using their professional skills (Hoffer, George, & Valacich, 2008)....   [tags: Information Systems, Software]

Linear Sequential Life Cycle Model Essay

- What is the waterfall methodology. According to several software engineering sites, the waterfall methodology is also known as the linear-sequential life cycle model and also known as the traditional approach to software development. The waterfall model is as follows: Requirement of gathering and analysis, flowing down to, System design, then flowing down to Implementation, followed by Testing, and then Deployment of the system, and the final phase of Maintenance. The idea of the waterfall approach is that once a phase is completed, the process continues to move down the chain until all of the phases are completed and there is a product to deliver; the method is unidirectional....   [tags: Agile software development, Waterfall model]
