iptables is the current host-based, Linux IP stateful firewall and routing service that can be enabled in your Fedora Linux Server. It controls incoming and outgoing network connections and either allows, disallows, or forwards requests based on a set of defined rule sets you configure within the firewall application itself.

You can download the CD or DVD ISO images from the related link for free. You can go to some computer stores and purchase a copy, too. It may come with a book for a small price.

If you're referring to LDAP, CN = common name

print the contents of a text file onto the screen (like the "type" command in DOS).

Linux and UNIX both are operating systems written in C and Assembly languages. UNIX is a primary operating system introduced in the year 1970 by Ken Thompson and others, while it is a multitasking and multiuser operating system. UNIX being a proprietary networking OS, its cost is high for a mainframe system. The end-users of UNIX are not authorised to change the kernel in any way as it results in the violation of the licence in the terms.

Later in the year 1991, a Finnish student named Linus Torvalds introduced the initial Linux kernel, which meant a clone of the UNIX. Linux is an open-source operating system and free for anyone to use and modify the code. Nowadays Linux OS is widely used in day to day life like Supercomputers, desktops, smartphones, web server, home appliances, washing machines, refrigerators, cars, modems etc.

Operating system: Each time when we turn on your computer, we can see and perform different activities on the system like write, read, browse the internet and watching a video. Well, all these activities are performed by an operating system or kernel. A kernel is a program which is the heart of any operating system, used to communicate between hardware and software. So, to work on the computer we need an operating system.

Nowadays Linux is in great demand and popularly used in everywhere. Linux is an open-source operating system which is freely downloaded and distributed over the internet. With time, Linux became an important backbone for an operating system like Knoppix, Debian, Ubuntu, and Fedora etc.

In order to print completed jobs on your printer, you just need to send the jobs to the relevant printers. You should ensure that you have the right settings for your printer.

ldlinux.sys is the name of the bootloader file used in SYSLINUX and ISOLINUX (used for booting Linux off of FAT32 and ISO9660 filesystems, respectively). It is loaded into memory by the BIOS on bootup. The loader then parses the configuration file (syslinux.cfg or isolinux.cfg) to know which kernel to launch, along with parameters to be passed to it.

I'm trying to go about on editing the vsftpd file so an account on my system, ftpadmin, should be the only regular user with access, including read and write access. But all other access should be anonymous and read-only. Any help to go about this would be greatly appreciated!

The installation process for Fedora on an Intel Core i3 is exactly the same as for any other processor type. Please see Fedora's documentation for instructions on how to install it.

Symettric Multi-Processing, or SMP, is actually not just a feature in Linux, but what it is is the capability of a kernel to support multiple CPUs or CPU cores.

Of course, usually to take advantage of SMP in an operating system, the program itself must at least be multi-threading aware.

It is used as a control device in a dedicated application

It can be. The kernel has a real time process scheduler, and there's a popular real time patchset that is often used to modify the kernel to be a more dedicated real-time system.

MULTIPROGRAMING .................. The term multiprograming denotes an operating system that,in addtion to supporting multitasking. In multiprograming more than one jobs are active in memory.Within a very small period more than one jobs are executed simultaneously. MULTITASKING ............... In general multiprogramming implies multitasking,but multitasking does not imply multiprogramming. A multitasking operating system is distinguished by its ability to support concurrent execution of two or more active processes. as discussed actually both multitasking and multiprogramming are same no other answer mentioned are justifiable.....

Most of the BANKS works on Mainframes which generally uses UNIX operating systems. But a BANK can use UNIX and flavours of LINUX (which is a UNIX flavor) and Windows Server ...

RTOS is a real time operating system.The important features are :- - The necessary signalling functions between interrupt routines and taskcodes are handled by RTOS. - It works as an independent system with no internal or external interdependencies. - There are no loop descisions in RTOS - The RTOS can suspend one task code subroutine in the middle order to run another - The time lag is veryless compared to other systems - There are no random time variables, this is good for a direct relationship between instruction and process. - Tasks are simpler to write. - Under most RTOS tasks are simply subroutines.

Which symbol is used with a variable to indicate to the script that you are reading the contents of that variable?

The only virtual machine that currently support USB passthrough to allow a guest operating system to use a USB device connected to the host is VirtualBox.
