Our operating systems homework help is the antidote to your complicated process synchronization questions

Process synchronization is the method of coordinating processes that use shared data. It helps in maintaining the consistency and efficiency of shared data. Process synchronization enables the scheduling of processes, ensuring that there is continued access to shared data and that there are no inconsistencies.
In process synchronization, different processes are managed in such a way that they do not share common resources at the same time. This avoids mistakes where one process may change the values in a resource and the second process may work with the same resource with wrong values and create errors. If a resource is critical, only one process should be allowed to use it. Only after this completes should the next process be allowed to use the critical resource. When the resource is free and several processes want to access it, it may be decided by which process has the next turn to use it. Another way is to use a hardware lock. A process is allowed into a resource only when it acquires a lock and locks it for itself. Then no other process is allowed to use the resource. A software solution is to use a semaphore. This is a variable shared between different processes. This semaphore informs the processes when they can use the critical resource.
Some of the topics under process synchronization include:
1.    Critical section problem
•    Mutual exclusion
•    Races
2.    Synchronization hardware
3.    Bakery algorithm
4.    Semaphores

A process is a dynamic activity in a computer, whose properties change with time. It is different from a program. At any time several processes are running to support the operating system, the hardware, and the software. The current status of a process is called a process state. The state includes the value of the program counter and values in various registers and relevant memory locations. At different times, process states are different. All processes are managed by the operating system. It allocates time to the CPU. It also gives them access to various resources like memory and hard disks. The OS maintains a process table to keep track of the details of all the processes, such as their states, use of different resources, and so on. If a process has all the resources it needs and is allowed to use the processor at this time, it is said to be running. If a process has access to all resources but is not allowed to use the processor, it is said to be ready. If a process does not have access to some necessary resources, it is said to be waiting. The operating system controls the ready and waiting processes utilizing queues.
A process is the execution of a program. A good example is if you open two tabs on your computer when you are running two processes. Operating systems allow processes to be divided into different threads to enable proper execution. When a process is divided into threads it’s held in a control block. Threads, therefore, enable the execution of different parts of the program code. In threads, different codes can be executed at the same time. Some of the popular concepts that you must be familiar with are:

Process management in xv6

This is the management of the commands that are used for programming in a specific topic. The process includes different sets of functions which include the environment variables, process identifier, and security context.

Process scheduling

Process scheduling includes the process manager which handles the removal of processes that are running from the CPU. It also selects another process. Scheduling is very important in multiprogramming since it allows one to either load a program or remove a running program. With process scheduling, a program can be removed without affecting other running programs


Threads (thread of execution) are parts of a program that can run independently of each other at the same time. During the execution of a program, several threads in it may begin, run and end, some of them simultaneously. This saves time and allows different resources to be used by different threads at the same time. It also allows better use of multi-processor architecture in a system. A thread is lightweight compared to a process. A thread runs only inside its program and can use only the resources allocated to its program. Each thread has a different program counter and execution stack. These give the context in which a thread runs. The execution stack provides memory to the thread. The program counter allows the thread to use control flows like goto and loops. Different threads in a program may share some memory locations and some other resources. For example, if some threads are busy in an intensive calculation, other threads may give a quick response to the user. More care is needed in the use of threads as they may reach their ends in the wrong order. Race conditions are also more probable in threads and it is more difficult to debug programs with threads.

Want Professional help with operating systems homework involving memory management?

Memory Management is a function of the operating system. The operating system keeps track of the use of primary memory by various processes. It allocates some blocks of memory to some processes. The OS keeps track of when some memory is no longer needed by a process. It releases that memory. The memory includes stack memory which contains variables and is declared at beginning of the program or a block. There is also heap memory. This contains memory allocated and released dynamically during the execution of programs. In the hardware, the memory may be divided into frames. The memory need by programs may be in pages. The memory needed by pages may be put into frames of hardware. Some parts of the frames may remain empty when the page does not fill it. Frames of a program may not be contagious. The operating system keeps track of which frame is used by which program. The OS may swap memory to and from primary memory to secondary memory as needed. Such secondary memory is called virtual memory. It enables programs that require more memory than can be satisfied by primary memory.

File systems and I/O management control how data is stored and also retrieved. Without the file system, data would not be arranged. In fact, it would be one large file in which one would not know where the second part of a file starts.

Availing operating systems project help on deadlocks from us gives you full value for your money

A deadlock occurs when one process holds some resource and is waiting for a resource held by a second process. At that time the second process is waiting for the resource held by the first process. Thus both processes cannot proceed further. For a deadlock to occur, there should be some exclusive resources. Only one process can use them at one time. One process should hold some such resources and be waiting for more exclusive resources. It cannot access these resources until the other process releases these. The other processes must also be waiting in a cyclic situation. One way to prevent this is to know in advance which resources a process will need and plan accordingly. Another way is for the operating system to take action to resolve the deadlock. The operating system can note which resource is held by which process and request for which resource is pending. The operating system can of its own, release some resources held by some processes to remove the deadlock. The third way is to ignore the problem as rare and reboot the system when it occurs.
We know how important your project is. Apart from summarizing what you have studied, it also makes up a huge chunk of your final grade. Completing a project on deadlocks effectively can be challenging.  However, our affordable operating systems project help service has got your back.

Popular topics covered by our operating systems coursework help service

We are an established platform that has cut a niche in the academic writing realm. Our operating systems coursework service is a one-stop solution to all homework in this area. Some of the popular topics that our experts have assisted in with include:

Scheduling and synchronization in xv6

Scheduling and synchronization in xv6 allow two processes which include creating a thread on the CPU and then allowing the scheduler thread to pick specific processes for execution. It also allows the switching of processes depending on their importance.

Memory management in xv6

Memory management in xv6 enables the allotment of processes based on their importance. A process is assigned its fair share of the available memory. When a process has removed a space created, then the memory is updated automatically. A different process then takes up the use of that memory when added.

The xv6 file system

Storing and organizing information in a hard drive may look simple but a lot is involved. The xv6 file system directs and stores all its data in an IDE disk. This reduces the chances of data loss because it supports crash recovery. This means that when there is a crash the systems will still work after recovery or restart. The xv6 file system also enables different processes to operate on the same system concurrently.

Task Scheduling

Different tasks are allowed the use of resources at different times. Some tasks may need to be completed before some other tasks can begin. Some tasks may have a higher priority than others. Some multi-processor systems may allow several tasks to run at the same time. A task scheduler receives requests from various processes for use of processors and resources. It decides which processes should be given which resources at a given time. A single CPU can handle only one program at a time. But if it rapidly switches between different programs, it appears as if the CPU is handling several programs at the same time. In a Round Robin scheduling, a task uses the CPU for some time. Then it stops and saves its values. The second task starts and uses the CPU for some time. This process continues and all tasks get their opportunity. Different tasks may be given small equal slices of time to use the processor. Another way is to give different priorities to tasks and allow tasks with higher priorities to operate first.

File System

Hard disks, flash drives, and optical disks all use different file systems. File systems organize the data into files for better convenience. Disk drives are the most common medium for storing files. Disk drives are divided into one or more partitions. Each partition has a file system. Data on disk drives can be written, erased, and rewritten easily. Access to data drives is direct. The time and effort needed to access different parts of the disk do not change much. The most basic layer of this file system is the physical layer. This includes electronic devices, motors, controls, magnetic media, etc. The input/output controls need device driver software. These are often written in assembly for efficiency. Their controller cards are assigned different ports to listen to. These also have special commands to use on them. The file allocation module can connect the physical blocks to logical blocks. The logical file system can contain metadata and block numbers of the files. It manages file names and directories/folders of files.

Primary and Secondary Storage

Secondary storage computers store data in primary storage or Random Access Memory for registers, main memory, ROM, PROM, cache, etc. Secondary storage like peripherals hard disks, flash drives, CDs, magnetic tapes, and optical disks are used for a large amount of data. Primary storage is faster but secondary storage is cheaper. Both are used depending on requirements. Secondary storage is persistent. Even in the absence of electric power data is maintained. In primary storage, when electricity is switched off, the data is lost. It is volatile. ROM and PROM are not volatile. Primary memory is faster than secondary memory by an order of a million times. To save time in accessing files on secondary memory, caching is used. When the secondary memory is accessed, some data is stored in primary memory anticipating that it will be used again in the future. This requires a judgment of what data will be needed later. File structures are designed in such a way that less disk access is needed.
