Operating system assignment help service by FreeAssignmenthelp.com is highly profetions by computer science students. OS is the software that administers the hardware and software resources of a computer and allows the system generated programming to perform a specific task. Operating system facilitates the users to communicate with the computer by interpreting manual input into machine language. Moreover, a computer is void without an operating system. So get operating system assignment help from FreeAssignmenthelp.com.The operating system supervises the Random Access Memory and all significant processes within the system.
History of operating system
The general features of an OS were first developed in the year 1960 that was capable of performing various operations at a synchronous speed automatically. Until 1960, no multiple features were include into it. After that 1960, the operating system was re-modification with hardware add-ons. The addition of hardware in operating enabled them to operate input/output interrupts, run-time library, parallel processors, link loading, spooling, multi-tasking, buffering, batch processing, record sorting etc.
Classification of operating system
With the advancement in technology, there have been immense improvements in operating systems. Our operating system assignment help experts discuss the various classifications of operating systems:
An operating system regarded as real time is a multi-tasker that aims to execute real-time applications. This operating system implement significant scheduling algorithm in order to response quickly in a deterministic manner. Real time OS are often based on time-sharing and event-oriented designs. Operating system assignment help experts throw further light on them:
- Event-Oriented: Swap tasks based on its priority and external events associated with it.
- Time-Sharing: Swap tasks based on their clock interrupts.

This is a type of operating system that allows access of a single computer by multiple users at the same time. Multi-user systems are designed respective to time-sharing configuration that enables the access of multiple users by sharing time period. For OS assignment help, trust UrgentAssignmenthelp.com.
In this system of OS, a group of independent computers are linked together to form a network and appear as a single computer. Moreover, when group of computers performs cooperative operations, it is known to be a distributed system. Our OS assignment help stresses on distributed Operating system.
When a particular virtual machine is used as a guest operating system but implemented as a tool for running multiple virtual machines, it is known as template. According to our OS assignment help experts, the template system of OS is utilized in managing cloud computing mechanism and virtualization.
This is a compact form of OS which is implemented to perform specific hardware-oriented functions. Students seeking OS assignment help should focus on this.
Application of operating system
Our OS assignment help experts highlight the wide-ranging applications of operating systems below:
Management of memory
OS administers both the primary and main memory of a computer. Main memory represents long arrays of bytes each having significant addresses location. Main memory accelerates the storage process which can be directly accessed through the CPU. Operating system performs the following tasks to manage memory. Our operating system assignment help experts emphasize on these:
- Track the functioning of primary memory i.e. trail the memory parts in use, parts that are not in use
- Allocate memory on request of processors
- It decides the percentage of memory allocation to processes in case of multi-programming systems. Our operating system assignment help experts can throw further light on it if you avail operating system assignment help
- De-Allocate memories when none of the processes need memory, especially at the time of termination
- Plays an efficient role to record the delay between service request and service response. Get more details through operating system assignment help samples.
Management of processor
Our operating system assignment help experts pinpoint the process scheduling performed by OS:
- Track the status of process and activity of processor (CPU). This task is advanced by using the program of traffic controller
- OS assigns a processor to a significant and viable process
- When there is no need of process, the OS de-allocates it from the processes

Management of file
This is an important topic in operating system assignment help. For the purpose of easy navigation and simplified usage, a file is ordered into directories. OS performs the following functions in order to manage a file.
- Track the location of information stored, status and use of data etc.
- Decides the allocation of resources to a significant program
- De-allocates the resources or data when no longer in use (important sub-topic in operating system assignment help)
- OS prevents the unauthorized access to data and programs by using passwords and security firewall.

Management of device
A device can perform network communication through its respective drivers. Operating system assignment help highlights the major role of OS in device management by the following activities.
- With the help of I/O controller, OS keeps track of all the devices
- Allocates devices to a particular program process
- Take necessary actions to determine efficient allocation of devices
- Also performs the de-allocation activities when needed
- Compilers, assemblers and interpreters are coordinated by the OS

Some examples of operating system
- GUI – Abbreviation of Graphical User Interface, it is an operating system that comprises of visual indicators like graphics and icon. This is an easy way to interact with the electronic devices rather using command line texts. GUI is implemented in all versions of Microsoft windows but not supported in MS-DOS.
Examples are GUI OS, Windows 98, Windows CE, System 7.x. Students seeking operating system assignment help, visit MyAssigmenthelp.com.
- Unix – Unix is the most popular and widely used operating system developed by the contribution of various programmers, institutes and organizations. This is a command line specific OS primarily, but also allows room for additional applications such as Windows-X. Unix is a command line oriented OS and hence consist of various shells. Moreover, Shell is a significant modification to the UNIX OS. Make your concept clear with operating system assignment help.
- Linux – It is an open-source and free operating system. The kernel of Linux performs on diverse platforms such as Alpha and Intel. Since it is a free expanded and distributed OS, the programmers can easily integrate new functions or eradicate programming bugs by accessing all of its source codes. For sample operating system assignment help, visit UrgentAssignmenthelp.com.
- Mac OS X – It is the successor of original Mac OS which was the primary operating system of Apple. Apple has recently launched the advanced version MAC OS 9 loaded with all new features unique from any other operating systems. Some of the distinct features of MAC OS 9 are 3D acceleration, inbuilt technologies like open GL, sharing facilities of files with other MAC users through internet network, 3.0 Color sync, Access to networks like TCP/IP, computing synchronization by the application of Hot Sync software.
