Multithreading is that the ability of a program or an OS process to manage its use by quite one user at a time and to even manage multiple requests by an equivalent user without having to possess multiple copies of the programming running on the pc . Each user request for a program or system service (and here a user also can be another program) is kept track of as a thread with a separate identity. As programs work on behalf of the initial request for that thread and are interrupted by other requests, the status of labor on behalf of that thread is kept track of until the work is completed.

A thread may be a path that's followed during a program’s execution. the bulk of programs written nowadays run as one thread. Let's say, for instance, a program isn't capable of reading keystrokes while making drawings. These tasks can't be executed by the program at an equivalent time. This problem is often solved through multitasking in order that two or more tasks are often executed simultaneously.

Multitasking is of two types: Processor-based and thread-based. Processor-based multitasking is completely managed by the OS, however multitasking through multithreading are often controlled by the programmer to some extent.

The concept of multi-threading requires an accurate perception of two terms – a process and a thread. 

Threading is employed widely in almost every field. Most generally it's seen over the web nowadays where we are using transaction processing of each type like recharges, online transfer, banking etc. Threading can be defined as a segment that offers the code into small pieces that are very lightweight and have less strain on CPU memory in order that it is often figured out and may achieve the goal within the aspired profession. The concept of threading is meant thanks to the matter of fast and regular changes in technology and fewer add different areas thanks to less application.
