What else can I help you with?
Why the interaction with hardware is limited to only one or two components of windows 2000xp?
Limiting access to hardware mainly to the HAL increases OS integrity because more control is possible.
What is one reason that interaction with hardware is limited to only one or two components of windows 2000xp?
Limiting access to hardware mainly to the HAL increases OS integrity because more control is possible.
Which operating system enables programs to access hardware devices directly?
the very basic os --MS-DOS allows uers to directly have access to hardware
What is one reason that interaction with hardware limited to only one or two components of the OS?
idek
Applications call on the OS to access hardware or other software by using a call?
API
How do you control hardware in C?
Platform-dependent. If you have an OS on your computer, then most likely you cannot access hardware directly from userland programs.
What manages the hardware components including the CPU memory storage and peripheral devices. O?
The operating system (OS) manages hardware components, including the CPU, memory, storage, and peripheral devices. It acts as an intermediary between users and the hardware, facilitating resource allocation, process management, and device communication. By efficiently coordinating these components, the OS ensures smooth operation and optimal performance of the computer system.
Does every program have access to all hardware?
No, most programs have no access at all to hardware. They call device drivers through the OS to perform input and output. These device drivers are custom written to access the hardware for the device they control. Modern computers use privileged instructions that cause an error if a user program tries to execute them to access hardware. The device drivers have the privilege to execute these instructions and access hardware.
What are three hardware and three software components of a computer?
Well, inside the computer, the three main hardware components are RAM (Random Access Memory), The CPU (Central Processing Unit) and the Power Supply (Battery). On the outside, you have the monitor (Screen), keyboard (typey thing) and mouse (What you move the cursor with).
What is the Layer between the OS and the hardware?
The HAL (hardware abstraction layer) is the layer between the OS and the hardware
Why do OS support all hardware types?
They do not. An OS is specific to processor and hardware type.
Mode is a processor mode in which programs have only limited access to system information and can access hardware only through other OS services?
user mode
