Unit 2 Operating Systems P2

The Operating system is one most important parts of anything that runs on technology. It manages the computers memory and processes the information for the software and hardware. There is different operation system for pc, tablets, smart cars, and smartphones.

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

As the OS control controls over all actions of computer so it is able to supply the detail or the elements that is needed by software to run from the hardware interface. Then it is acts as a resource manager as it is important component of a computer which controls all the components of the computer system. When the hardware provides the basic computing resources, the application program routine define the ways in which these resources are used to solve the computing problems of the users and the operating system controls and coordinate the use of hardware among the various application programs for the various users. It also handles storage management by controlling the storage management. Either than that, it is enables user to perform various tasks such as creating directories and files, copying and moving files, renaming files and deleting files. Then it keeps track of the exact location of files o hard drive through specific type of file system. The system tools are used to monitor computer performance, debug problems, or maintain parts of the system. A set of libraries or functions which programs may use to perform specific tasks especially relating to interfacing with computer system components. Despite that it provides a set of reusable system

Operating systems are vital to the use of computers, they tell the machine what it is, what language, where the programs are, when things are stored, how to do things, the instruction codes to do everything. The system is in charge of security such as ensuring that unauthorised users do not access the system. There are many types of operating systems, a few are listed below:

Irregular Access memory is inside the PC which store the information and work with capacity memory to make lessen less and influence space for essential things to like record and documents in light of the fact that for individual protection.

Operating systems have the responsibility to ensure that users do not access the system illegally. They also perform different tasks such as managing system resources, communicate between software and hardware, monitoring performance and operate utilities and applications.

Operating systems were not in existence before the 1960s. The definition of operating systems is a program designed to run other programs on the computer and is the most important

The operating system is the set of instructions that direct the computer to accomplish specific tasks such as document production and spreadsheet calculations.

The operating system manages and interacts with the computer hardware, peripherals like your mouse and keyboard, device drivers, and applications software. The computer’s OS (operating system) acts as the main resource manager.

In conjunction with computer hardware, the importance of a user-friendly operating system and it's ability to perform an diverse range of tasks is the

Systems software includes the programs that are dedicated to managing the computer itself, such as the operating system, file management utilities, and disk operating system.

Operating systems and application software are essential in the running of computers. The operating system is the most important piece of software on a computer. It controls the computers software/hardware, memory and processing. It also allows the user to control the computer without knowing its operating language. An example of an operating system is Mac OS X. Application software is often designed for a specific purpose such as word processing, Web browsers or spreadsheets etc. These applications can often be used to do other jobs than just the one intended. For example you could use word to edit photos but this is not the applications intended use, so it will not have advanced image-editing features which a program like Photoshop would

Windows address space can be larger or smaller than the actual memory installed on the machine. Windows handles memory management with two responsibilities. The primary is to map or translate the processors virtual address space to the physical memory. The second responsibility is to manage the swap file between the hard drive and Random Access Memory (RAM). Windows memory management also includes memory mapped files. Allowing files to be placed into RAM, sequential file

The same is real for Linux system. There are a large number of customized and typical Linux system programs.

All the details of the operating system has completed its specific application in order to work more closely. Hopefully this example has a clear idea about computer operating system.
