processes are concurrent if they exist at the same time.concurrent process can function completely indepently to one another. two process are concurrent if their execution can overlap in time; that is, the execution of the secon process starts before the first process completes. concurrent processes generally interact through the following mechanisms: Shared variables Message passing

concurrent server is a server which can handle multiple requests at a time.
Concurrent processes require access to shared resources, synchronization mechanisms to coordinate access to those resources, and a way to manage communication and data exchange between processes. The operating system must provide support for process management, scheduling, and inter-process communication to enable concurrency. Additionally, proper error handling and robust design are essential for successful execution of concurrent processes.
The three most common concurrent transaction executive problems are uncommitted data, lost updates, and inconsistent retrievals. It is believed that concurrency control can help these problems.
In geometry, three or more lines are said to be concurrent if they intersect at a single point.
Concurrent Execution in DBMSDatabase Management systems usually allow multiple transaction to run concurrently even though it causes a lot of complications with consistency of data. Ensuring consistency when multiple transactions execute concurrently, requires extra effort. It is much simpler to allow only one transaction to run at a time but concurrent execution of transactions has its own advantages: Improved throughput and resource utilization :Concurrent execution means that CPU doesn't have to be idle while it is waiting for I/O activity to complete. This is because transactions can run in parallel on CPU along with I/O activities. This means that resources can be utilized effectively by having multiple transaction run concurrently.Less waiting time : Without concurrency, a short transaction might need to wait for a long transaction to finish causing delay in its execution. With multiple transactions running on the system, new transactions have to wait for less time before getting executed.
Concurrent lines or line segments occur when 3 or more lines meet at the same point
View Serializable is a correctness criterion in database management systems that ensures that the final result of executing concurrent transactions is the same as if they were executed one after the other. This property helps maintain data consistency and ensures that the database remains in a consistent state despite concurrent transaction execution. Transactions are said to be view serializable if their interleaved execution produces the same results as if they were executed sequentially.
