Operating system
An operating system (OS) is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details.
A hypervisor is a software that creates and manages virtual machines within an operating system. It acts as a mediator between the physical hardware and the virtual machines, allowing multiple operating systems to run on a single physical machine. The hypervisor allocates resources, such as CPU, memory, and storage, to each virtual machine, ensuring they operate efficiently and securely.
an operating system is a software progrmme required to mange and opearate a computing divice like computers, supercomputers, smartwatches, tablets, etc. It is the operating system that eliminates the need to know coding language to interact with computing divices. It is a layer of graphical user interface which acts as a platfrom between the user and the computer hardware moreover the operating system manges. the software side of a computer and controls programs exacution.
The software that acts as a liason between the user and the computer's hardware and software is called as an Operating System. Microsoft's Windows operating system is the most popular and widely used. Linux is another which is free and is an open source operating system.
it is operating system.........
Technically speaking linux is a kernel. The kernel is the part of the operating system that acts as a middleman/translator between the hardware and the software.
Operating System, such as Windows or Linux.
An operating System is the most important software running on your computer. It acts as a bridge between the user and machine. It provides an environment for application to run. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.
Operating systems do 2 things: (1). Providing an easier abstraction layer (system calls) for user programs to access the real HW machine. (2). It manages the system resource. It this view, the shell is not considered as part of the operating system because: (1). It acts as a interpreter(from user command to system calls) only, and (2). It runs in user mode, and (3). It is highly possible to replace the shell if you don't like one.
Operating System have a major component called KERNEL that is designed to interact with hardware .Kernel acts as an interface between OS Shell & Hardware.
generally a program which lets you interact with your hardware and acts as a user interface is the Operating System.
