Answer 1

What is a thread?

Ans:

A further abstraction of a process used to facilitate interactions between code pieces with similar goals related to a parent process.

A process is a set of instruction intended to perform a particular task, the idea of the thread is dividing the single process into multiple lightweight processes and achieve parallelism by performing the threads according to availability of resources and nature of the task.

Unlike processes which are running in different memory spaces, threads of the same process run in shared memory space.
