Which of these applications is NOT an example of distributed computing?
A. Excel: Excel, developed by Microsoft, is a spreadsheet application that can handle complex computations. To enhance performance, Excel is designed to use all of a computer's processors simultaneously for concurrent computation, especially when dealing with spreadsheets containing numerous formulas.
B. The Great Internet Mersenne Prime Search (GIMPS): GIMPS is a collaborative project aimed at discovering Mersenne prime numbers. Volunteers contribute by running the GIMPS application on their personal computers. This application checks numbers for primality and communicates with a central server when a Mersenne prime is found. As of 2019, GIMPS had successfully identified 17 Mersenne primes.
C. Beowulf Cluster: A Beowulf cluster consists of a group of computers networked together, running software that facilitates efficient communication between them. These clusters are typically employed for computationally intensive tasks, such as speech recognition and astrophysics simulations.
D. SiteWhere: SiteWhere is an open-source platform designed for establishing sensor networks. It allows users to install the platform on a server and configure sensors to interact with this server. Applications of SiteWhere include home automation, vehicle tracking, and other similar use cases.
