UNIX
Q.How are devices represented in UNIX?
A.Devices in UNIX are represented by files. These are special files located in the )dev directory. Hence in UNIX, every piece of hardware is a file. This device file allows us to access the hardware.UNIX represents all devices as files. These files are located in the directory /dev. That is why the devices and other files are accessed in a similar way.Devices file which is specified as 'block special file' with some similar characters of a disk file. A device which is specified as a 'character special file' with some characteristics that is similar to a keyboard.For instance, the following command;
Less -f /dev/hda is not a file in the 'real' sense. When read, it is actually reading directly from the first physical hard disk of your machine.
What else can I help you with?
Which operating system supports the ZFS file system?
Sun's Solaris OS supports the ZFS file system natively.
How does the hardware interact with operating system?
Operating System have a major component called KERNEL that is designed to interact with hardware .Kernel acts as an interface between OS Shell & Hardware.
What does the operating system OS do?
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.
How a operating system is related to computer hardware?
The operating system (OS) controls the hardware. A successful computer system will have hardware and an operating system. Application software is not required. All operating systems have a low level, or machine language to run the operation system and control all hardware.
What are the layers of operating system?
Hardware is the Inner most layer of the OS. Then the Kernal Then the Shell
What are the components of OS?
The components of an operating system (OS) include the kernel, which manages system resources and hardware interactions; the user interface, which allows users to communicate with the system (command-line or graphical); system libraries, which provide essential functions for application programs; and device drivers, which enable the OS to interact with hardware peripherals. Additionally, the OS includes utilities for system management, file management, and process management, ensuring efficient operation and resource allocation.
What is os and function of os?
An operating system (OS) is software that acts as an intermediary between computer hardware and users, managing hardware resources and providing a user interface. Its primary functions include managing system resources (like CPU, memory, and storage), facilitating file management, and enabling communication between software applications and hardware components. Additionally, an OS provides security and access control to ensure safe operation of the system. Examples of operating systems include Windows, macOS, and Linux.
What part of the operating system interfaces with the hardware?
the kernel is the part of the OS that interfaces with the hardware
What file system must be used to encrypt an entire hard drive?
If you mean full Hard disk encryption, right down to the FAT Table, then I would recommend using a third party program that supports such functions such as "Truecrypt". NTFS for example supports file encryption and windows has "Bitlocker" which supports a type of drive encryption and file container encryption. There are also hardware based methods which allows for OS transparent hard drive encryption that would prevent the drive from being read in another system without the hardware key. File system is USUALLY not important. Since encryption at a hardware level bypasses the OS and is transparent to it.
What four operational and organizational things does an OS provides?
An operating system provides a bridge between the hardware and applications, it creates a file system to store data, it manages applications, and it interprets user commands.
Is utility software part of OS?
Utility software is not technically part of the operating system (OS) itself, but it complements the OS by providing additional functionality. While the OS manages hardware and software resources, utility software performs specific tasks such as file management, system optimization, and antivirus protection. Many utilities may be included with an OS or can be installed separately, enhancing the overall user experience and system performance.
Which operating system supports the ZFS file system?
Sun's Solaris OS supports the ZFS file system natively.
What is hardware controler?
hardware control is a operating system. OS is used to control the elctronic devices(hardware) via user. because user can't control hardware directly so, OS is used to interface computer & user
What do you call a library of hardware drivers that operate between the OS and hardware that is installed on the system?
It sounds to me like you are referring to the kernel of the operating system.
What does OS X do?
OS X is an operating system. To put it simply, it ties together your computers hardware and software.
The OS is responsible for interacting with hardware?
As we know that the OS is used to operate every device through the drivers present in the OS. So without the OS we cannot communicate with the devices (hardware). For every device some drivers are required to run them and these drives are provided by the operating system. So by this we can see that the OS provides the interface between the user and the hardware, as user does not make the device work he uses the OS.
How does the hardware interact with operating system?
Operating System have a major component called KERNEL that is designed to interact with hardware .Kernel acts as an interface between OS Shell & Hardware.
