The memory space, where a given application is executed is called - process. A Process is the memory set aside for an application to be executed in.
Within this process the thing, which is really executed is the thread.
The key difference is that processes are fully isolated from each other; threads share (heap) memory with other threads running in the same application.
Threads share the address space of the process that created it; processes have their own address.
Threads have direct access to the data segment of its process; processes have their own copy of the data segment of the parent process.
Threads can directly communicate with other threads of its process; processes must use inter-process communication to communicate with sibling processes.
Threads have almost no overhead; processes have considerable overhead.
New threads are easily created; new processes require duplication of the parent process.
Threads can exercise considerable control over threads of the same process; processes can only exercise control over child processes.

Plumbing pipe threads are squared and conduit pipe threads are tapered.
screw thread are single threads which means they are not double
The threads
different paths of control in a program that a computer might run at the same time if it has parallel processing support for multithread execution. threads and processes are two ways of supporting multitasking on a uniprocessor or multiprocessing on a multiprocessor. threads are lighter weight: take less OS resources to implement but only support limited protection and security. processes take more OS resources but can support full protection and security. Many operating systems support both processes and threads, allowing each process to have many threads.
-> Difference between process based and thread based multitasking: 1) threads share the same address space where as process doesn't. 2) context switching between threads is usually less expensive than between processes. 3) cost of communication between threads is relatively low.

Capillitial threads are very minute forms of slime mold. A columella has numerous threads radiating from all sections of the cell.
A thread is like any other class, except that there is the capacity to run multiple threads - multiple processes - simultaneously.

A cagoule is more puffy and has threads usually hanging out
Process --1------------m-- Threads 1 process to many threads Bring up your Task Manager (if you are using a windows), Performance tap, you can see the number of process and the number of threads, usually the number of threads is a lot higher than the number of processes.
In operating systems, a child process is a new process created by an existing process, which operates independently and has its own memory space. Whereas a thread is a subset of a process, sharing the same memory space and resources as the parent process. Threads are lighter weight and more efficient compared to processes in terms of resource utilization.
