 # DevTest Labs concepts
 
 This article lists key DevTest Labs concepts and definitions:
 
 ## Lab
-The infrastructure that encompasses a group of resources, such as Virtual Machines (VMs), that lets you better manage those resources by specifying limits and quotas.
+A lab is the infrastructure that encompasses a group of resources, such as Virtual Machines (VMs), that lets you better manage those resources by specifying limits and quotas.
 
 ## Virtual machine
 An Azure VM is one type of [on-demand, scalable computing resources](/azure/architecture/guide/technology-choices/compute-decision-tree) that Azure offers. Azure VMs give you the flexibility of virtualization without having to buy and maintain the physical hardware that runs it.
 
 [Overview of Windows virtual machines in Azure](../virtual-machines/windows/overview.md) gives you information to consider before you create a VM, how you create it, and how you manage it.
 
 ## Claimable VM
-An Azure Claimable VM is a virtual machine available to any lab user with permissions. Lab admins can prepare VMs with specific base images and artifacts and then save them to a shared pool. Then the lab users can claim a VM from the pool when they need one with that specific configuration.

 A VM that is claimable isn't initially assigned to any particular user, but will show up in every user's list under "Claimable virtual machines". After a VM is claimed by a user, it's moved up to **My virtual machines**  and is no longer claimable by any other user.

 Policies help in controlling cost in your lab. For example, you can create a policy to automatically shut down VMs based on a defined schedule.
 
 ## Caps
-A mechanism to minimize waste in your lab. For example, you can set a cap to restrict the number of VMs that can be created per user, or in a lab.

 ## Security levels
 Security access is determined by Azure role-based access control (Azure RBAC). To understand how access works, it helps to understand the differences between a permission, a role, and a scope as defined by Azure RBAC.
