When a user starts a computer portions of the operating system load into the computers hard disk from memory?
False
What are the tree major areas in which the operating system divided services?

What are the two function of the operating system?
.The operating system acts as the interface between the user and the computer. The two major functionalities of an OS are 1)Managing hardware/memory resources. 2)Providing an interface for the user to communicate with the computer
Single user vs multi user vs network user?
single user os are those os where only one user access the resources of the operating system at a time .the resources of operating system 'll not allocate to any other user.multi user operating system is that operating system where the resources of operating system can be accessed by more than one user at a time ,means to say; multi users can access the operating system simultaniously or any other way.network user operating system is also the multi user operating system but the different is that the users are geographically remote user connected through a network media but share the same capy of operating system

When the computer is turned off the operating system resides in memory.?
When the computer is turned off, the operating system is not resident in memory; instead, it is stored on the hard drive or other storage media. Memory (RAM) is volatile, meaning it loses its contents when power is lost. Upon restarting the computer, the operating system is loaded from the storage into memory, allowing it to manage hardware and provide an interface for user applications.
Distinguish between multiprogramming operating system and time sharing operating system?
time sharing operating system is user interactive, but multiprogramming operating system need not be user interactive
What is the Process of loading operating system software into a computer main memory from disk?
The process of loading operating system software into a computer's main memory from disk begins when the computer is powered on and the BIOS or firmware performs a power-on self-test (POST). Afterward, it locates the bootloader on the bootable disk, which is responsible for loading the operating system. The bootloader reads the operating system files from the disk and transfers them into the main memory (RAM). Once loaded, the operating system initializes hardware components and prepares the system for user interaction.
