Reliability, availability and serviceability
Reliability, availability and serviceability (RAS), also known as reliability, availability, and maintainability (RAM), is a computer hardware engineering term involving reliability engineering, high availability, and serviceability design. The phrase was originally used by International Business Machines (IBM) as a term to describe the robustness of their mainframe computers..
Reliability, Availability, Serviceability
<system, design, hardware, software> (RAS) Three key
attributes of a computing system design. See reliability,
availability, and serviceability.
The term "RAS" is fairly common in the computing industry
(particularly computers and storage) as computing becomes more
fundamental. For example, a vehicle may depend on dozens of
computers, and the consequences of the failure can be
significant (e.g., an ambulance's engine won't start).

Reliability (computer networking)
ABILITY OF A COMPUTER NETWORK PROTOCOL TO NOTIFY THE SENDER OF WHETHER DELIVERY OF DATA WAS SUCCESSFUL
Reliability properties; Strong reliability properties; Reliable messaging; Reliable messaging service; Reliable messaging system; Reliable communications; Assurance (computer networking); Reliable delivery
In computer networking, a reliable protocol is a communication protocol that notifies the sender whether or not the delivery of data to intended recipients was successful. Reliability is a synonym for assurance, which is the term used by the ITU and ATM Forum.

Reliability, availability and serviceability
Reliability, availability and serviceability (RAS), also known as reliability, availability, and maintainability (RAM), is a computer hardware engineering term involving reliability engineering, high availability, and serviceability design. The phrase was originally used by International Business Machines (IBM) as a term to describe the robustness of their mainframe computers.
Computers designed with higher levels of RAS have many features that protect data integrity and help them stay available for long periods of time without failure This data integrity and uptime is a particular selling point for mainframes and fault-tolerant systems.
