In every Unix-like operating systems device files are used as interface to device drivers. Every device is represented in file system with a special file, these special files are called as Device Files.
There are two standard types of device files: character special and block special.
Character special files are used to interface character devices. Character devices transfer data in terms of character. Example of character devices mice, serial modems.
Block special files are used to interface block devices. Block devices transfer data interms of blocks. Example of block devices hard disks, CD-ROMs.

Which os treats hardware as a file system?
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.
How are devices treated in C plus plus?
On some platforms (unix, for example) devices are handled as special files.
What is the three categories of users in a Unix environment?
Unix has the following categories of users: Superuser - root account, can do anything on the system ordinary user - has no special privileges restricted user - is restricted in what they can do in the shell and programs they can run.
What is difference between block special file and character special file?
A block special file that provides access to a device that transfers in groups of a fixed size. For example, a disk. A character special file that provides access to a device that transfers in increments of a single character; for example, a terminal.

What operating system is frequently used by scientists and programmers?
UNIX is the operating system of choice for scientists, programmers, and other such professionals because of the following benefits:Local processing facilities.Compilers.Editor.Document preparation system.Efficient file system and access control.Mountable and de-mountable volumes.Unified treatment of peripherals as special files.The network control program (NCP), is integrated within the Unix file system.Network connections treated as special files which can be accessed through standard Unix I/O calls.The system closes all files on program exit."desirable to minimize the amount of code added to the basic Unix kernel".
How are devices represented in UNIX?
In UNIX, devices are represented as special files located in the /dev directory. These files can be categorized into two types: character devices, which transmit data one character at a time, and block devices, which handle data in blocks. Each device file has a unique major and minor number that identifies the device driver and the specific device instance, respectively. This abstraction allows users and applications to interact with hardware devices through standard file I/O operations.
