- 5. What is system software? The system software is a computer program, which is designed to run computer hardware and applications. The system software makes your system faster, effective, and safe. When installing the operating system, the system software is already installed on the computer. System files include function libraries, system services, printer, and other hardware drivers, system preferences, and other configuration files.
- 6. Here are the features of system software. Usually written in a low-level language. It has a high speed. Less interactive. The system software is closer to the system.
- 7. There is another software on your computer- application software. Application software is a program that does actual work for users. It is mainly created to perform user-specific tasks. Now, let’s see the differences between system software and application software. System software is the general software, while application software is special software. System software can run independently, but application software cannot run independently. System software is designed to manage system resources, such as memory and process management, security, etc., while application software is designed to meet the needs of users to perform specific tasks. System software is written in low-level languages such as machine or assembly language, while application software is a high-level language used to write application software.

- 9. What is OS An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. An operating system is software that enables applications to interact with a computer's hardware. The software that contains the core components of the operating system is called the kernel. The primary purposes of an Operating System are to enable applications (spftwares) to interact with a computer's hardware and to manage a system's hardware and software resources.
- 10. Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, etc. Today, Operating systems is found almost in every device like mobile phones, personal computers, mainframe computers, automobiles, TV, Toys etc.
- 11. Security is provided by OS to the user data and prevents unauthorized access. 1. System performance is boosted with the help of the OS 2. Various applications or tasks and the number of users doing the tasks are accounted for by OS 3. The computing system shows some errors 4. Many users use the computing system the hardware and these errors are logged in the OS 5. The main memory is managed by OS 6. OS organizes the file system
- 12. here are following 8-components of an Operating System: Process Management I/O Device Management File Management Network Management Main Memory Management Secondary Storage Management Security Management Command Interpreter System
- 13. A process is program or a fraction of a program that is loaded in main memory. A process needs certain resources including CPU time, Memory, Files, and I/O devices to accomplish its task. The process management component manages the multiple processes running simultaneously on the Operating System. A program in running state is called a process
- 14. One of the purposes of an operating system is to hide the peculiarities of specific hardware devices from the user. I/O Device Management provides an abstract level of H/W devices and keep the details from applications to ensure proper use of devices, to prevent errors, and to provide users with convenient and efficient programming environment. Following are the tasks of I/O Device Management component: Hide the details of H/W devices Manage main memory for the devices using cache, buffer, and spooling Maintain and provide custom drivers for each device. File Management A files is a sequence of bits, bytes, lines or records whose meaning is defined by its creator and user.
- 15. The definition of network management is often broad, as network management involves several different components. Network management is the process of managing and administering a computer network. A computer network is a collection of various types of computers connected with each other. Network management comprises fault analysis, maintaining the quality of service, provisioning of networks, and performance management.
- 16. Network management is the process of keeping your network healthy for an efficient communication between different computers. Following are the features of network management: Network administration Network maintenance Network operation Network security
- 17. Memory is a large array of words or bytes, each with its own address. It is a repository of quickly accessible data shared by the CPU and I/O devices. Main memory is a volatile storage device which means it loses its contents in the case of system failure or as soon as system power goes down. The main motivation behind Memory Management is to maximize memory utilization on the computer system.The operating system is responsible for the following activities in connections with memory management: Keep track of which parts of memory are currently being used and by whom. Decide which processes to load when memory space becomes available. Allocate and deallocate memory space as needed.
- 18. The main purpose of a computer system is to execute programs. These programs, together with the data they access, must be in main memory during execution. Since the main memory is too small to permanently accommodate all data and program, the computer system must provide secondary storage to backup main memory. Most modern computer systems use disks as the principle on-line storage medium, for both programs and data. Most programs, like compilers, assemblers, sort routines, editors, formatters, and so on, are stored on the disk until loaded into memory, and then use the disk as both the source and destination of their processing. The operating system is responsible for the following activities in connection with disk management: Free space management Storage allocation Disk scheduling
- 19. The operating system is primarily responsible for all task and activities happen in the computer system. The various processes in an operating system must be protected from each other’s activities. For that purpose, various mechanisms which can be used to ensure that the files, memory segment, cpu and other resources can be operated on only by those processes that have gained proper authorization from the operating system. Security Management refers to a mechanism for controlling the access of programs, processes, or users to the resources defined by a computer controls to be imposed, together with some means of enforcement.For example, memory addressing hardware ensure that a process can only execute within its own address space. The timer ensure that no process can gain control of the CPU without relinquishing it. Finally, no process is allowed to do it’s own I/O, to protect the integrity of the various peripheral devices.
- 20. One of the most important component of an operating system is its command interpreter. The command interpreter is the primary interface between the user and the rest of the system. Command Interpreter System executes a user command by calling one or more number of underlying system programs or system calls. Command Interpreter System allows human users to interact with the Operating System and provides convenient programming environment to the users.Many commands are given to the operating system by control statements. A program which reads and interprets control statements is automatically executed. This program is called the shell and few examples are Windows DOS command window, Bash of Unix/Linux or C-Shell of Unix/Linux.
- 21. An Operating System provides services to both the users and to the programs. It provides programs an environment to execute. It provides users the services to execute the programs in a convenient manner. Following are a few common services provided by an operating system Program execution I/O operations File System manipulation Communication Error Detection Resource Allocation Protection
- 22. Security refers to providing a protection system to computer system resources such as CPU, memory, disk, software programs and most importantly data/information stored in the computer system. If a computer program is run by an unauthorized user, then he/she may cause severe damage to computer or data stored in it. So a computer system must be protected against unauthorized access, malicious access to system memory, viruses, worms etc

- 25. Windows is a collection of programs known as an operating system (OS) that controls a PC (personal computer). First produced by Microsoft in November 1985, it has been frequently updated since, as computer memory has got bigger, as processing chips have got faster and, of course, when the internet was invented. Prior to Windows, PCs were operated by a series of text commands. Windows' key benefits and features Allows the user to interact with the computer (through the keyboard, mouse, microphone, etc.).
- 26. Controls the storage of data (images, files, music). Controls hardware attached to the computer such as webcams, scanners and printers. Helps to open and close programs (word processors, games, photo editors, etc.), and gives them part of the computer’s memory to allow them to work. Controls what access to a computer different users have and the computer's security. Deals with errors and user instructions, and issues simple error messages. Promotes multitasking by allowing the user to do several things on the computer at once – for example, watch a video while writing a letter.
