-
Each term represents a different way of measuring system performance. Taken together, response time, bandwidth, throughput, and turnaround time provide a comprehensive view of system operations and performance.
-
Response time
measures the overall time between a request for system activity and the delivery of the response to the user.
Throughput
measures actual system performance under specific circumstances and is affected by network loads and hardware efficiency.
turnaround time
time applies to centralized batch processing operations, such as customer billing or credit card statement processing and measures the time between submitting a request for information and the fulfillment of the request.
Release Methodology
Disadvantages:
- Users expect a rapid response to their problems and requests, but with a release methodology, new features or upgrades are available less often.
- Even when changes would improve system efficiency or user productivity, the potential savings must wait until the next release, which might increase operational costs.
Advantages:
- When a release methodology is used, all changes
are tested together before a new system version is released.
- This approach results in
fewer versions, less expense, and less interruption for users.
- Using a release methodology also reduces the documentation burden, because all changes are coordinated and become effective simultaneously.
is a system of numbered releases used by organizations(especially software vendors) that helps organize maintenance changes and updates
Configuration Management
