The Functionality of Linux

• Linux has the same features as almost any commercial 32-bit UNIX operating system such as multitasking, multiuser, and multiplatforms.

• Linux has memory protection between processes, so that one program cannot bring the whole system down. In addition, Linux only reads from disk those parts of a program that are actually used, so it can increase CPU speed and decrease memory use.

• Linux either supports several common filesystem, including minix-1, Xenix, UMSDOS, or has a built-in filesystem of its own, and names up to 255 characters long.

• In Linux, virtual memory is using paging to disk method to swap a separate partition and a file in the filesystem and allow more swapping areas during runtime. Moreover, it contains a unified memory pool for user programs and disk cache, so that the system can run large programs properly and still reduce the disk cache.

• Linux conforms to the X/Open and POSIX standards for UNIX-like operating systems and comes configured with an extensive array of system utilities and general software. It is also fully compatible with System V and BSD extensions at both of the source code and binary form.

• One of Linux's greatest features is its advanced modular networking capabilities. Linux supports Internet TCP/IP via ethernet, modems, or packet radio. Linux also supports most of the standard networking services such as ftp, telnet, email, gopher, WWW and much more. Linux is capable of acting as both a client and a server for each of these services.

• Linux also has its built-in CD-ROM file system which can read all standard formats of CD-ROMs and provide a better performance on disk running.
