There are two types of lithosphere: - Oceanic lithosphere, which is associated with Oceanic crust - Continental lithosphere, which is associated with Continental crust Oceanic lithosphere is typically about 50-100 km thick (but is no thicker than crust beneath the mid-ocean ridges), while continental lithosphere is about 150 km thick.
Pooling is a feature of SAS clients that increases the efficiency of connections to SAS. Pooling is only available for SAS Workspace Servers. When a SAS client application is configured to access a pooled workspace server, the client application maintains a collection of reusable workspace server processes called a pool. By reusing server processes, pooling avoids the processing that is associated with creating a new process for each connection. If your client application uses frequent, quick connections to SAS, pooling might greatly improve your server performance.
A media pool is a collection of tapes or disks that have the same management properties. All media in a Removable Storage system belong to a media pool, and each media pool holds only one type of media. Data management programs use media pools to gain access to specific tapes or disks within a library.
