Sep 03, · This paper explains what a real-time operating system (RTOS) is, how real-time operating systems are useful for measurement and control applications, and how they differ from standard general-purpose operating systems like Windows Apr 01, · System Programming can be defined as the act of building Systems Software using System Programming Languages. According to Computer Hierarchy, one which comes at last is Hardware. Then it is Operating System, System Programs, and finally Application Programs. Program Development and Execution can be done conveniently in System Programs operating system, executed on the top of a bare machine of hardware that allocates the basic resources of the system (e.g., CPU, memory, devi ce driver, communication port, etc), and supervises the execution of all applications within the system. Some popular commercial and Open Source operating systems are

The operating system is a system program that serves as an interface between the computing system and the end-user. Operating systems create an environment where the user can run any programs or communicate with software or applications in a comfortable and well-organized way. Furthermore, an operating is a software program that manages and controls the execution of application programs, software resources and computer hardware.
In Batch Operating System, paper on operating system is no direct interaction between user and computer. Therefore, the user needs to prepare jobs and save offline mode to punch card or paper tape or magnetic tape. After creating the jobs, hand it over to the computer operator; then the operator sort or creates the similar types of batches like B2, B3, and B4.
Now, the computer operator submits batches into the CPU to execute the jobs one by one. After that, CPUs start executing jobs, and when all jobs are finished, the computer operator provides the output to the user. It is the type of operating system that allows us to connect many people located at different locations to share and use a specific system at a single time. The time-sharing operating system is the logical extension of the multiprogramming through which users can run multiple tasks concurrently.
Furthermore, it provides each user his terminal for input or output that impacts the program or processor currently running on the system. It represents the CPU's time is shared between many user processes. Or, the processor's time that is shared between multiple users simultaneously termed as time-sharing.
The Embedded operating system is the specific purpose operating system used in the computer system's embedded hardware configuration. These operating systems are designed to work on dedicated devices like automated teller machines ATMsairplane systems, digital home assistants, and the internet of things IoT devices.
It shows the improper use of system resources. Hence, the operating system introduces a new concept that is known as multiprogramming. A multiprogramming operating system refers to the concepts wherein two or more processes or programs activate simultaneously to execute the processes one after another by the same computer system. It improves the use of system resources, thereby increasing system throughput.
Such a system is known as a multiprogramming operating system. A network operating system is an important category of the operating system that operates on a server using network devices like a switch, paper on operating system, router, or firewall to handle data, applications and other network resources. It provides connectivity among the autonomous operating system, called as a network operating system.
The network operating system is also useful to share data, paper on operating system, files, hardware devices and printer resources among multiple computers to communicate with each other.
A distributed operating system provides an environment in which multiple independent CPU or processor communicates with each other through physically separate computational nodes.
Each node contains specific software that communicates with the global aggregate operating system. With the ease of a distributed system, the programmer or developer can easily access any operating system and resource to execute the computational tasks and achieve a common goal.
It is the extension of a network operating system that facilitates a high degree of connectivity to communicate with other users over the network. It is the type of operating system that refers to using two paper on operating system more central processing units CPU in a single computer system.
However, these multiprocessor systems or parallel operating systems are used to increase the computer system's efficiency. With the use of a multiprocessor system, they share computer bus, clock, memory and input or output device for concurrent execution of process or program and resource management in the CPU, paper on operating system. For example, real-life situations governing an automatic car, traffic signal, nuclear reactor or an aircraft require an immediate response to complete tasks within a specified time delay.
When the first electronic computer was developed init was created without any operating system. In early times, paper on operating system, users have full access to the computer machine and write a program for each task in absolute machine language. The programmer can perform and solve only simple mathematical calculations during the computer generation, and this calculation does not require an operating system.
The first operating system OS was created in the early s and was known as GMOS. General Motors has developed OS for the IBM computer. The second-generation operating system was based on a single stream batch processing system because it collects all similar jobs in groups or batches and then submits the jobs to the operating system using a punch card to complete all jobs in a machine. At each completion of jobs either normally or abnormallypaper on operating system, control transfer to the operating system that is cleaned after completing one job and then continues to read and initiates the next job paper on operating system a punch card.
After that, new machines were called mainframes, which were very big and used by professional operators. During the late s, operating system designers were very capable of developing a new operating system that could simultaneously perform multiple tasks in a single computer program called multiprogramming. The introduction of multiprogramming plays a very important role in developing operating systems that allow a CPU to be busy every time by performing different tasks on a computer at the same time.
During the third generation, there was a new development of minicomputer's phenomenal growth starting in with the DEC PDP These PDP's leads to the creation of personal computers in the fourth generation. The fourth generation of operating systems is related to paper on operating system development of the personal computer.
However, the personal computer is very similar to the minicomputers that were developed in the third generation, paper on operating system. The cost of a personal computer was very high at that time; there were small fractions of minicomputers costs. A major factor related to creating personal computers was the birth of Microsoft and the Windows operating system. Microsoft created the first window operating system in After introducing the Microsoft Windows OS, Bill Gates and Paul Allen had the vision to take personal computers to the next level.
Therefore, they introduced the MS-DOS in ; however, it was very difficult for the person to understand its cryptic commands. Today, Windows has become the most popular and most commonly used operating system technology. And then, Windows released various operating systems such as Windows 95, Windows 98, Windows XP and the latest operating system, Windows 7.
Currently, most Windows users use the Windows 10 operating system. Besides the Windows operating system, Apple is another popular operating system built in the s, and this operating system was developed by Steve Jobs, a co-founder of Apple.
They named the operating system Macintosh OS or Mac OS. JavaTpoint offers too many high quality services.
