A web server is a computer that runs websites. It's a computer program that distributes web s as they are requisitioned.
The basic objective of the web server is to store, process and deliver web s to the users. These web s are mostly static content that includes HTML documents, images, style sheets, test etc.
A software for which the original source code is made freely available and may be redistributed and modified according to the requirement of the user. Open source software is that by which the source code or the base code is usually available for modification or enhancement by anyone for reusability and accessibility.
Open source code is the part of software that mostly users don't ever see. The Rapid Application Development or RAD model is based on Model needed tonight and iterative model with no or less specific planning. In general, RAD approach to software development means putting lesser emphasis on planning tasks and more emphasis on development and coming up with a prototype. In disparity to the waterfall model, which emphasizes meticulous specification and planning, the RAD approac.
Pseudocode is an informal way of programming description that does not require any strict programming language syntax or underlying technology considerations. It is used for creating an outline or a rough draft of a program. System deers write pseudocode to ensure Model needed tonight programmers understand a software project's requireme. Software maintenance is a part of Software Development Life Cycle. Its main purpose is to modify and update software application after delivery to correct faults and to improve performance. Software is a model of the real world. When the real world changes, the software requires alteration wherever possible.
Description: Software maintenance is a vast activity which includes optimization, error. The spiral model is similar to the incremental development for a system, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, De, Construct and Evaluation. A software project repeatedly passes through these phases in iterations called Spirals in this model. Description: These phases are - Planning: This phase starts with the gathering of business requireme.
The Prototyping Model is a Systems Development Methodology SDM within which a paradigm output or an early approximation of a final system or product is constructed, tested, and then reworked. It is done till an appropriate paradigm is achieved to help develop the entire system or product. This model works best in situations when all the details or requirements are not known well in advance. Systems de is the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements.
It is the process of defining, developing and deing systems which satisfies the specific needs and requirements of a business or organization.
Description: A systemic approach is required for a coherent and well. To prevent incorrect operation of a software or system, debugging is used to find and resolve bugs or defects. When various subsystems or modules are tightly coupled, debugging becomes harder as any change in one module ma. The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach.
It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion. This model is divided into different phases and the output of one phase is used as the input of the next phase. Every phase has to be completed be.

Systems De Definition: Systems de is the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements.
Description: A systemic approach is required for a coherent and well-running system. Bottom-Up or Top-Down approach is required to take into all related variables of the system. A deer uses the modelling languages to express the information and knowledge in a structure of system that is defined by a consistent set of rules and definitions.
The des can be defined in graphical or textual modelling languages. Some of the examples of graphical modelling languages are a. Flowchart : A schematic or stepwise representation of an algorithm. De methods: 1 Architectural de: To describes the views, models, behaviour, and structure of the system.
Web Server Definition: A web server is a computer that runs websites. Description: The main job of a web server is to display the website content. If a web server is not exposed to the public and is used internally, then it is called Intranet Server. All websites on the Internet have a unique identifier in terms of an IP address.
This Internet Protocol address is used to communicate between different servers across the Internet. These days, Apache server is the most common web server available in the market. Apache is an open source software that handles almost 70 percent of all websites available today. Most of the web-based applications use Apache as their default Web Server environment. IIS is owned by Microsoft.
Definition: The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach. Every phase has to be completed before the next phase starts and there is no overlapping of the phases. Description: The sequential phases described in the Waterfall model are: 1.
Requirement Gathering- All possible requirements are captured in product requirement documents. Analysis Read - the requirement and based on analysis define the schemas, models and business rules. System De -- Based on analysis de the software architecture. Implementation Development of the software in the small units with functional testing. Integration and Testing Integrating of each unit developed in phase and post integration test the entire system for any faults. Deployment of system - Make the product live on production environment after all functional and nonfunctional testing completed.
Maintenance Fixing issues and release new version with the issue patches as required. Advantages: 1. Easy to use, simple and understandable, 2. Easy to manage as each phase has specific outputs and review process, 3. Clearly-defined stages, 4. Works well for smaller projects where requirements are very clear, 5.
Process and output of each phase are clearly mentioned in the document. Disadvantages: 1. When the product is in testing phase, it is very difficult to go back and change something which is left during the requirement analysis phase.
Risk and uncertainty are high. Not advisable for complex and object-oriented projects. As testing is done at a later phase. So, there is a chance that challenges and risks at earlier phases are not identified.
