Serviceability includes various methods of easily diagnosing the system when problems arise. Early detection of faults can decrease or avoid system ...
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
Serviceability engineering may also incorporate some routine system maintenance related features (see: Operations, Administration and Maintenance (OA&M.)) A service tool is defined as a facility or feature, closely tied to a product, that provides capabilities and data so as to service (analyze, monitor, debug, repair, etc.) that product.
In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: . Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability
In comparison to science education and mathematics education, computer science (CS) education is a much younger field. [13] In the history of computing, digital computers were only built from around the 1940s – although computation has been around for centuries since the invention of analog computers. [14]
