1. Explain the Thread concept and how it helps to achieve concurrency.
A thread can be defined as a path of execution present in the process. A process consists of multiple threads. It is also known as a lightweight process. We can divide a process into multiple threads to achieve the parallelism. Each thread is allotted at slice of time on the CPU and then the control is switched over each other as it initiates a task which need some waiting Time and does not utilise the CPU. It may complete the time allotted to it on the CPU. The multithreading is a technique which is used to allow for simultaneous execution of multiple parts of a program to get the maximum utilisation of a CPU. The concurrency can be defined as the ability of a program for handling multiple things at a time and we can use multithreading concept to achieve this. 
When we use multiple threads along with a single code then the application will have to transition Back and forth to produce an illusion of the multitasking.
