LINUX (Continues.)


Maximum Number of Processors:

Number of bits: 32 or 64 (depending on the processor used)

Kernel: LINUX

“The Linux kernel was originally written by Linus Torvalds (hence the name “Linux”), and it maintained by a team of developers. The kernel itself is released under the GPL (GNU Public License).” —Rich Steiner (See also: http://www.linuxhq.org
    
Some versions of LINUX use the MACH kernel. These include: MkLinux (PowerPC), Intel MkLinux, and HP/PA MkLinux.

POSIX: compatible

Peripherals: “most PC hardware” —Kristian Elof Sørensen
    
John Kirch: “Ease of configuration and being able to configure a server without causing downtime is yet another aspect of functionality: ‘Some versions of UNIX (Linux, for example) support loadable device modules. This means you can boot Linux and reconfigure its support for hardware and software on the fly. For example, you can boot Linux without support for the SCSI card you have installed. You simply load support for that SCSI card when you need to access one or more of the SCSI-connected devices, such as an optical disk for backup. You can unload the SCSI driver when you’re finished. You can also freely load and unload support for sound cards, network cards — even file systems such as HPFS, FAT, VFAT, and others (an NTFS driver is in the works).“—Nicholas Petreley, The new UNIX alters NT’s orbit: The re-emergence of UNIX threatens to modify the future direction of NT, NC World, April 1998.”

File Systems Supported:

  • preferred file system: ext2fs
  • file systems can read/write/format: ext2fs, extfs, FAT
  • file systems can read/write: FAT32, VFAT, FFS, coda, NFS, Minix, Xenix, UMSDOS, xiaf, SMB
  • file systems read only: NTFS, UFS, HPFS-2, HPFS, sysvfs, adfs, ROMFS
  • file systems read only and can write through optional software: ISO 9660, Commodore 1541/1581 (shareware at
http://www.npsnet.com/danf/software/
  • file systems can read/write/format through third party or optional software: HFS

Other Systems Emulated:

Graphics Engine: X Window

Text Command Shell: UNIX shells (default shell is bash)

“The properties of the command-line interface depend to some extend on the shell involved. Linux uses shells which tend to be close of (or derived from) UNIX shells. Typical shells are bash, tcsh, and zsh.” —Rich Steiner

User Interface (graphic): XWindows
    
“Linux uses the X windows system (usually) as a graphical interface, which gives it the capability to distribute displays over a network, and which allows for windowing on the desktop. The X window managers or environments each have their own names (like AfterStep, fvwm, twm, olvwm, Enlightenment, KDE, etc). The X server which is normally used in Linux is XFree86.” —Rich Steiner (See also: http://www.xfree86.org
