Titlesort descending Summary
Hardware partition

A discrete and isolated subset of processor, memory, and other resources within a physical server, treated as its own server for licensing purposes.

Hardware thread

A discrete computational unit to which the operating system can assign an independent instruction stream; sometimes relevant under the Per Core License Model and Server/CAL License Model.

Home Use Program

Permits employees of organizations purchasing Office applications with SA (Software Assurance) as well as other eligible organizations to buy discounted Per User subscriptions to Office 365 Home or Office 365 Personal, or Per Device licenses for client applications. See HUP for a detailed entry.

HPC Workload

Refers to a scenario involving Windows Server-based high performance computing (HPC) clusters licensed via volume licensing programs where client access is “free,” meaning neither Windows Server CALs (client access licenses) nor External Connectors are required.

HUP

The Home Use Program (HUP) permits employees of organizations purchasing Office applications with SA (Software Assurance) as well as other eligible organizations to buy discounted Per User subscriptions to Office 365 Home or Office 365 Personal, or Per Device licenses for client applications.

Hyper-threading

A hardware performance enhancement technology that allows each physical core within a physical processor to execute two (rather than one) independent instruction streams simultaneously; can be a factor under the Per Core License Model.

Hypervisor

Technology that allows multiple VMs (virtual machines), each running its own OSE (Operating System Environment) and applications, to execute concurrently on a physical device without interfering with one another.
