Description: A host-based system is a type of distributed computing model where the main processing is carried out on a host computer, while other computers, known as clients, rely on it to perform specific tasks. In this model, the host computer acts as a central server that manages resources, data, and applications, allowing clients to access these resources over a network. This approach facilitates centralized management and resource optimization, as the processing load is concentrated on the host machine, which can result in more efficient performance. Additionally, host-based systems often provide a simplified user interface on clients, as much of the processing and business logic is executed on the server. This type of architecture is particularly useful in environments where a high degree of collaboration and access to shared data is required, such as in businesses and organizations that use enterprise applications or centralized databases. Scalability and ease of maintenance are other notable features of these systems, as updates or modifications to the infrastructure can be made on the host computer without needing to intervene in each individual client.
