Peer-to-peer systems were originally made famous by file sharing applications, but they have proven to be useful for various purposes. The purpose of this thesis is to introduce some of the benefits and issues in peer-to-peer systems from user\u2019s perspective. This thesis is done as a systematic literature review. The first part of the thesis is about defining peer-to-peer as well as client\u2013server model, which is critical in order to understand the peer-to-peer architecture. A comparison of these revealed that peer-to-peer systems involve the user more as they are based on cooperative resource sharing rather than asymmetrical request-response communication. This thesis also highlights some of the most used applications for peer-to-peer systems, and the attempt to find the benefits and issues from user perspective is based on these examples. Some of the benefits found include operational reliability, improved performance caused by user cooperation and a good base for privacy. On the other hand issues found were the phenomenon of free-riding and legal issues on resource sharing.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-06-23T07:22:19Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-23T07:22:19Z (GMT).
