SLA - Computer Definition
A portion of a service contract that addresses service parameters such as availability (uptime and downtime), mean time to respond (MTTR), mean time to repair (MTTR), and overall network throughput, all of which can be crucial in a mission-critical and time-sensitive application environment. See also downtime, throughput, and uptime.

(2) (Service Level Agreement) A contract between the provider and the user that specifies the level of service expected during its term. SLAs are used by vendors and customers as well as internally by IT shops and their end users. They can specify bandwidth availability, response times for routine and ad hoc queries, response time for problem resolution (network down, machine failure, etc.) as well as attitudes and consideration of the technical staff. SLAs can be very general or extremely detailed, including the steps taken in the event of a failure. For example, if the problem persists after 30 minutes, a supervisor is notified; after one hour, the account rep is contacted, etc.
