P2P Computing Concepts and Their Discussions

Peer-to-peer is a technology concept applied at different levels of the systems architecture. Its main characteristics are direct interaction and data exchange between peer systems. It is the basis for decentralized distributed computing. The concept is widely deployed in different contexts and no formal definition exists. This paper gives an overview of the different areas peer-to-peer technology is used and introduces the main characteristics of peer-to-peer systems. It also discusses the issues and problems encountered when deploying peer-to-peer technology

Development by Using the Test Driven Approach

Test-Driven Development (TDD) is a software development technique consisting of short iterations where new test cases covering the desired improvement or new functionality are written first, then the production code necessary to pass the tests is implemented, and finally the software is refactored to accommodate changes. Test-Driven Development is related to the test-first programming concepts of Extreme Programming, begun in the late 20th century, but more recently is creating more general interest in its own right. In this paper, I am describing the test driven development cycle, development style ,benefits, limitations and how to do testing in different languages
