LAN Intrinsic Software
A standalone program that has been modified to work on a LAN by including concurrency controls such as file and record locking is an example of LAN intrinsic software. This type of software is specifically designed and developed to function within a local area network (LAN) environment.

Explanation
LAN intrinsic software refers to software programs that are explicitly built to take advantage of the capabilities and features offered by a LAN. In the context of the given question, the program has been modified to incorporate concurrency controls, such as file and record locking, which allow multiple users on the LAN to access and manipulate data simultaneously while preventing data inconsistencies and conflicts.

Concurrency Controls
Concurrency controls are mechanisms implemented in software to manage and regulate access to shared resources in a multi-user environment. In the case of a LAN, where multiple users may access the same program or data simultaneously, concurrency controls become essential to ensure data integrity and prevent data corruption.

File and Record Locking
File and record locking are specific types of concurrency controls used to manage access to files and records within a program. File locking ensures that only one user can modify a file at a time, preventing conflicts and inconsistencies that may arise from concurrent modifications. Record locking, on the other hand, allows multiple users to access a file simultaneously but restricts their ability to modify the same record simultaneously.

LAN Intrinsic Software Example
In the given scenario, the standalone program has been modified to include file and record locking mechanisms, which enable concurrency controls and facilitate proper data management in a LAN environment. This modification transforms the program into LAN intrinsic software, as it has been specifically tailored to function effectively within the LAN's context.

By incorporating concurrency controls, the modified program can handle multiple users accessing and modifying data concurrently without compromising data integrity. This ensures that users can work collaboratively and efficiently within the LAN environment, taking full advantage of the network's capabilities.
