Programming Applications and Frameworks (IT3030)

1. Compare and contrast web applications with web services, indicating the need for web services. WEB SERVICES 1.Web services are server-side application components ,which provides a set of services. 2.Services of the web service are exposed via an API                      Modular,well-defined,encapsulated interfaces are used for loosely coupled integration                         between applications and systems. 3. Loosely coupled architecture,and interacts with client-side components via the API 4.Multiple types of clients can communicate with the web service via the API                     Browser- based- clients ,non- browser- based-clients(mobile apps),other web services                                     ...

Tutorial -04 01.Explain the term “distributed systems”, contrasting it from     “distributed computing” Computer based distributed systems mainly divided in to two types.according to distribution of the components. 1.Standalone Systems(Desktop Applications) 2.Distributed Systems Distributed computing  is a field of computer science that studies  distributed systems .  A  distributed system  is a  system  whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another. 02.Compare and contrast the standalone systems with distributed systems, providing examples for advantageous use of both Standalone Systems - 1.All the components are executed with a single line.                                     2.Do not need a network       ...
