Question

List the components of the process that are shared across all threads in a multithreaded process. Briefly explain why it is important that the other components of the process be unique to each thread.

• Program Text

• PID

• Program Counter

• CPU Registers

• Data Section

• Stack

• Heap

• Open Files

Answer 1

Program Text :

The process that can be defined as the represetation of the activity of an entity and it representes the basic unit of the work that should we implimented in the system.

In order to put this in the format of the simple terms , we can write that in the format of program in a file and then we can execute the program .

This is all becomes a process and it performs all the tasks in a program .

PID or Process Identification :

It means the Process Identification .

It provides the unique identification to the system in order to identify the hardware type of item or the some of the types of the registers.

And it is always a non-negitive number.

Program Counter :

The program counter is a type fof register in a computer processors and it contains the address of the instruction that is been execute at the present time

If any one of the instruction that can be fetched then the program counter should incresed and store their value by 1.

It mainly contains the address of the current instruction in the specific tyoe of register.

CPU registers :

The CPU register is a type of register and that can holds the data in a small type of format .

The holding data can be placed on the computer processor in a system in order to work .

The registers can also hold the instruction types , and provides the storage address and some kind of the data .

Here we have the some instructions those can be specify the registers as a part of the instrction .

Data section :

The data section is a type of portion where we can place the diffrent types of data in order to prcocess and fetch the execution .

And we commonly dentoedint the format of the (.data).

It is the type of portion of the object file and that is corresponding to the virtual address space .

And that virtual address space that contains the static variables ,gloabal variables , local variables.

STACK :

It is the type of data structure and we can use this stack in ordr to store the collection of the objects.

And the individual operations like adding of an item and the storing of an item process with the help of the push operation .

In order the retreive those value we have the pop operation for the fetching of the process.

And this stack has the several types of application the the computer programming.

HEAP :

It is the special type of the tree data structure and that is in the type of tree format where the tree is a complete binary tree.

This Heaps can be of two types mainly the MIN_HEAP and the MAX_HEAP.

And these can be represented the key that can be preseneted in the root of the value of the node and that must be the grateset among the keys presented from all of its children nodes.
