We are living in the age of information. Information has been expanded exponentially. This is causing some really challenging hardship to IT industry as well as academia. We need new techniques and tools to manage large volume of data, Big data. Form this prospective, the concept of distributed system were emerged. The primary objective of this concept was to reduce the computation time on large amount of data and sharing of resources. Later on the concept of grid computing , more specialized form of distributed computing became buzzword in IT field. At present these concept were merged into new concept such as big data, machine learning and cloud computing. NO body want bye a mainframe or rack server, instead they bye or leased required resource on cloud infrastructure managed by AMAZON or Microsoft AZURE. It cost minimum as well as required no time for set up and configurations.
On this regards, I have prepared a small presentation on Introduction to distributed system, lecture given at CDCSIT, TU, First Semester. The power point slide can be reached here. The reference taken in preparing these slide was the text book " operating system concept" by Abraham Silberschatz.
