Thread vs Process

[ramsun]

Hello, I am student of the BSC.I.T. and I want to know the difference between the Thread and Process. I have try to check the details about it, but I am not able to get the details of it. So, if anyone from you knows what is the difference between them then please help me to get that.

Hello, if you are talking about the process then it is a collection of the virtual memory space, your code, all of your data and all of the resources which you use. And a thread is a code that is gets executed in serial manner within that process. So, if you consider the thread then it is executed by the processor. So, each and every application contains one process minimum. But, your single process can have multiple threads.

If you are using java programming language then your thread implementation can be performed as below:
First you will define a class which contains that thread as below:

class Testing extends Thread

• When the parent thread creates object and it gets executed by the use of the function as name of the start().
• It will simply create a child thread and then it will call the run() function.
• And the termination of the thread will be done when you will make use of the stop() function.

Hey, you need to consider the points given below for getting the difference between the Thread and Process:
Threads :.
● If you are using Thread then it will directly share your memory.
● It will also share you file descriptors.
● It have the capability to share your filesystem context.
● You are able to share signal handling.

Processes:
● It won't share your memory by default.
● In case of the processes it is not possible to share file descriptors.
● You are not able to share the filesystem context.
● Don't share signal handling.

Hello, for creating a thread or process you need to make use of the following syntax:
Creating a thread:

clone(c_stack=1x230cc540, flags=CLONE_TA|CLONE_FT|
CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|
CLONE_SETTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID,
parent_tidptr=1x230cc3e4, tls=1x230cc562, child_tidptr=1x230cc3e4)

Creating a process:

clone(c_stack=0, flags=CLONE_CHILD_CLEARTID|
CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f4936ecc770)

Hey, if you are making use of the thread in your process then it will simply share a single address space and also able to access one another variable. But, your processes can be executed on different addresses and it is necessary to inter process the communication for exchanging the information. In other term you can simply call that the process which is Heavyweight is called as a Process and the process which is a Lightweight is called as a Thread. If you make use of the thread than process then it will provide you faster response. And that is why it will be used for the switching between the threads.
