Operating Systems

A computer can run without an operating system but each piece of software would have to be written to "talk" directly to the computer's hardware - displaying something on the screen, saving to discs etc. An operating system provides a standard layer that connects to the hardware so that applications can ask the OS to do something and not worry about the details.

#include <stdio.h>

int curr[5][5],maxclaim[5][5],avl[5];

int alloc[5]={0,0,0,0,0};

int maxres[5],running[5],safe=0;

int count=0,i,j,exec,r,p;

int main(){

printf("\nEnter the number of resources: ");

scanf("%d",&r);

printf("\nEnter the number of processes: ");

scanf("%d",&p);

for(i=0;i<p;i++){

running[i]=1;

count++;

}

printf("\nEnter Claim Vector: ");

for(i=0;i<r;i++) scanf("%d",&maxres[i]);

printf("\nEnter Allocated Resource Table:\n");

for(i=0;i<p;i++){

for(j=0;j<r;j++) scanf("%d",&curr[i][j]);

}

printf("\nEnter Maximum Claim table:\n");

for(i=0;i<p;i++){

for(j=0;j<r;j++) scanf("%d",&maxclaim[i][j]);

}

printf("\nThe Claim Vector is: ");

for(i=0;i<r;i++) printf("\t%d",maxres[i]);

printf("\nThe Allocated Resource Table:\n");

for(i=0;i<p;i++){

for(j=0;j<r;j++)

printf("\t%d",curr[i][j]);

printf("\n");

}

printf("\nThe Maximum Claim Table:\n");

for(i=0;i<p;i++){

for(j=0;j<r;j++) printf("\t%d",maxclaim[i][j]);

printf("\n");

}

for(i=0;i<p;i++)

for(j=0;j<r;j++) alloc[j]+=curr[i][j];

printf("\nAllocated resources:");

for(i=0;i<r;i++) printf("\t%d",alloc[i]);

for(i=0;i<r;i++) avl[i]=maxres[i]-alloc[i];

printf("\nAvailable resources:");

for(i=0;i<r;i++) printf("\t%d",avl[i]);

printf("\n");

//Main procedure goes below to check for unsafe state.

while(count!=0){

for(j=0;j<r;j++){

if(maxclaim[i][j]-curr[i][j]>avl[j]){

running[i]=0;

A multiprocessor system is any device with multiple processors(processing cores).

These days, you can buy up to an 8 core PC, (apple's new mac pro) http://blogs.zdnet.com/Apple/?p=485

But most people with gaming PC's have at least a duo-core processor. They used to be very expensive, but now they are affordable. But you'll usually hear that term associated with PC or computing devices. It makes everything faster, especially multitasking.

Windows, Mac

vxworks is used to control network and communication devices. vxworks is similar to unix but it uses less processing power than unix.

One can find an open source document management system from numerous sites. Examples of such sites include Alfresco, Contineo, Iron Mountain and File Expert.

Yes, the PC's operating system manages hardware, runs applications, provides an interface for users, and stores retrieves and manipulates files. An OS would be, for example, Windows 10.

An operating system is made simpler to understand and use by abstracting complex details through user-friendly interfaces and streamlined functionalities. By presenting information and options in a clear, intuitive manner, users can perform tasks without needing to understand the underlying complexities. Additionally, automation of routine processes and the use of graphical user interfaces (GUIs) allow users to interact with the system more easily, reducing cognitive load. This simplification ultimately enhances user experience and accessibility, enabling a broader range of individuals to utilize the technology effectively.

Backing store management refers to the operating system's ability to manage secondary storage, such as hard drives or SSDs, to support processes that cannot be fully loaded into main memory (RAM). It involves techniques like paging and swapping, where data is temporarily stored on disk to free up memory for active processes. This function ensures efficient use of memory resources, enables multitasking, and maintains system performance by allowing larger applications to run on limited physical memory. Overall, backing store management plays a critical role in system stability and responsiveness.

No, Windows 7 Home Basic (and Window 7 Starter) does not support themes on its own. You can, however, download and install Personalization Panel which can run themes on your Home Basic computer.

Your computer do not find a operating system to boot up (Windows, Linux etc.) It's needed for you to navigate visuals on your screen.

This error might display if your boot-files are damaged or missing, or your hard drive is disconnected or damaged.

You will have to replace the faulty hardware/files. Reinstalling your OS is usually a solution for this.

acc. to me,multiprogramming is based on system level and multitasking is based on user level.operating system can execute a program or application once at a time.it means the code related to other applications would be stored in operating systems but it will activate when that particular application is activated by user. acc. to me,multiprogramming is based on system level and multitasking is based on user level.operating system can execute a program or application once at a time.it means the code related to other applications would be stored in operating systems but it will activate when that particular application is activated by user. acc. to me,multiprogramming is based on system level and multitasking is based on user level.operating system can execute a program or application once at a time.it means the code related to other applications would be stored in operating systems but it will activate when that particular application is activated by user.

An interactive or hands on computer system provides online communication between the users and the system.The users gives instuction to the operating system or to a program directly,and receiver an immediate response.

I'd say this question isn't very specific, but PCs definitely use what can be called a "client" OS while servers use a "server" OS.

To execute code and provide a graphical user interface.

Well, microsoft's windows operating system is on about 90% of the computers currently in use, so I would assume a number close to that would be the % of the computers coming preloaded with windows.

There is nothing in the CPU hardware itself. This is handled by "anti-virus" software.
