What is the difference between processes and threads?
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.

Is thread same as a function?
No. A process is composed of one or more threads. Threads can invoke any function of the process.
Which is not shared by the threads of the same process?
stack
What resources are used when a thread is created?
When a thread is created the threads does not require any new resources to execute the thread shares the resources like memory of the process to which they belong to. The benefit of code sharing is that it allows an application to have several different threads of activity all within the same address space. Whereas if a new process creation is very heavyweight because it always requires new address space to be created and even if they share the memory then the inter process communication is expensive when compared to the communication between the threads
What is thread based multitasking?
-> 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.
Describe the actions by the Kernel to switch between different kernel-level threads belonging to the same process?
1- State of current process is Saved. 2-Restore State of incoming process.

What of these components are shared by a multithreaded process?
There r some resources shared by different threads o the same process while some r not. The threads shares the address space,file,global variables. But each threads has its own stack , copy of registers(including PC).
What is the differences between a process and a thread in Linux?
A single process can have multiple threads that share global data and address space with other threads running in the same process, and therefore can operate on the same data set easily. Processes do not share address space and a different mechanism must be used if they are to share data.If we consider running a word processing program to be a process, then the auto-save and spell check features that occur in the background are different threads of that process which are all operating on the same data set (your document). processIn computing, a process is an instance of a computer program that is being sequentially executed[1] by a computer system that has the ability to run several computer programs concurrently. Thread A single process may contain several executable programs (threads) that work together as a coherent whole. One thread might, for example, handle error signals, another might send a message about the error to the user, while a third thread is executing the actual task of the...
What is the difference between process and thread in net?
A process is a collection of threads that share the same virtual memory. A process has at least one thread of execution, and a thread always run in a process context. Thread is used to allocate and distribute the CPU work scheduling, many programs a re assigned to different threads and they are most of the time independent of each other. Eg: We can open many instance of MS word and MS Excel in our PC, all are monitored and managed by threads. Process is nothing but a program in execution, many threads can run under a process or many thread can combined under the one thread.
What level of classification do humans share with lizards?
Humans and lizards share the same level of classification as vertebrates, belonging to the Phylum Chordata.
What resource are typically shared by all of the threads of a process?
There r some resources shared by different threads o the same process while some r not. The threads shares the address space,file,global variables. But each threads has its own stack , copy of registers(including PC).

What chemical processes do produces and consumers not share?
they do not share the same process (which is photosynthesis)
What is a thread and how does it relate to a process?
A process is composed of one or more threads of execution. Multiple threads allow a process to perform two or more operations concurrently. This is particularly useful in machines with two or more processors as the threads can execute simultaneously. All the threads of a process run in a shared memory space; separate processes run in separate memory spaces. A process must have at least one thread, the primary thread. However, threads can spawn new threads as required. Each thread has its own call stack but shares the same data segment and virtual address space as the process.
