Process is a programm under execution in main memory. Or in other world when a user wants to execute a programm which resides on secondary memory it must be placed in to the primary memory for the execution then it is called as process.
An operating system manages the working operation of a computer
MS-DOS Command promt is the third operating system
1. What are the two kinds of installation of an operating system? Explain Briefly.
The booting process of an operating system is the sequence of events that occurs when a computer is powered on or restarted, leading to the loading of the operating system into memory. It begins with the BIOS or UEFI firmware performing hardware checks and initializing system components, followed by locating and loading the bootloader from the designated boot device. The bootloader then loads the operating system kernel into memory, which initializes system services, drivers, and user interfaces, ultimately preparing the system for user interaction. This entire process ensures that the hardware and software are ready for operation.
The Kernel
True
process
it is known as the operation instrument
An operating system is software that resides between user applications and hardware. It's job is to manage hardware resources and allocate them to the user applications through processes such as memory management and process scheduling.
This is not always true, it depends on the operating system and the bootstrap process.
Operating System
Also known as the process state, the execution context is the internal data the Operating system uses to control or supervise a process.
