What type of hardware does Unix run on?
Unix can be run on a variety of server, mainframe, and workstation devices.
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 block special in unix?
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.
What is VxWorks?
vxworks is used to control network and communication devices. vxworks is similar to unix but it uses less processing power than unix.
What is root directory and how it is represented?
root directory is the top of the directory tree. it is \ on windows (or c:\ d:\ etc.) and / on unix/linux
How is Topmost directory in unix represented?
Directory tree structure in Unix always starts at the top node, or "root" node. It contains all of the major level subdirectories underneath it. The root directory is called "/" (root).
What folder do you look in for information to modify a device file in Linux?
Answer:Linux and Unix store their devices in /dev. Character and Block devices are there (all devices for that matter).That said, it should be understood that devices are treated somewhat differently under Linux/Unix than some other operating systems. On a Linux/Unix system, all devices are treated as a file, hence the /dev directory and all of the files that reside in it. You may notice that an 'ls -al' listing of /dev produces different output than it does in other directories. Instead of file sizes you'll see the device major and minor numbers. These are represented by the bold type below for the console device.crw------- 1 root root 5, 1 Sep 11 10:41 consoleIf you write a program to open the /dev/console and write to it, whatever is written to the device will show up on the machine's console terminal.

What is QNX?
QNX - is a piece of UNIX-based software for use on various devices. These include desktop computers, mobile phones and laptops.
Why Linux operating system is written in c language?
Because Linux is "sort-of-a-copy-of-Unix" (which is not), and Unix was written in C. C was created to write Unix. Most portable operating systems or serious embedded devices are written in some incarnation of C and C++. Including MS-DOS and earlier copies of Window$ (which I am sure still uses it)
Control devices represented by these initials PCV and EGR?
Positive Crankcase Ventalation and Exhaust Gas Recirculation
What is logical and physical server?
Physical servers (also referred to as boxes) are represented by physically or virtually separate computers with their own operating systems (Linux, FreeBSD Unix, or Windows).
