Part A
Define the term Grid Computing. Explain how grid computing is different from cluster computing.
Answer
Grid computing is a distributed computing model where a network of geographically dispersed, heterogeneous computers work together to solve large-scale problems, treating the entire network as a single virtual supercomputer. Unlike cluster computing, which typically involves a group of homogeneous nodes located in close proximity connected via a high-speed local network to perform parallel tasks, grid computing focuses on resource sharing across administrative domains, often utilizing heterogeneous hardware and slower wide-area network connections.
What is meant by cloud computing? Explain the need for cloud computing.
Answer
Cloud computing is an on-demand delivery model for IT resources—such as servers, storage, databases, and software—over the internet with pay-as-you-go pricing. The need for cloud computing arises from the requirement for scalability (adjusting resources based on demand), cost-efficiency (avoiding heavy upfront capital expenditure on hardware), high availability, and the ability to rapidly deploy applications without managing underlying physical infrastructure.
