Hello Musa,
There are a lot of details when it comes to the licenses, and it can get confusing which option is the best for you.
According to the NI Software Policies, there are two types of licenses - non-concurrent and concurrent.
The non-concurrent licenses are assigned to specific users or computers at certain sites. The number of licenses assigned cannot exceed the number of non-concurrent seats purchased. There are two types of non-concurrent licenses: named-user and computer-based.
The concurrent license is for a software installed on unlimited computers at certain sites if no more than X instances of the software are in use at any given time, where X equals the number of concurrent seats purchased. This license type can only be purchased as part of a VLA. There are two types of concurrent licenses: managed and unmanaged.
To read more on each type, check out the following article:

You decide whether the license will be user- or computer-based after the purchase. The following forum reply explains the difference between user-based and computer-based license types:
Re: volume license questions - NI Community
To participate in the Volume License Program, you need to:
- Purchase five or more licenses of the same type of NI development software.
- Designate an individual to act as an NI Volume License Agreement (NI VLA) administrator.
- Follow the usage guidelines as described in the NI Software License Agreement.
As for the second questions, you must renew your subscription to keep using the software. Therefore, when you purchase a development license with a subscription, after the expiration of the term, you won't be able to use the development environment unless you renew the subscription.
Please let me know if you need any further clarification.
