Linux

No, it is not OS is not a Linux based operating system. Giggles is a search engine and created Chrome Operating system. Linux is its own brand of operating system.

There's no specific equivalent. Several programs can be used for creating equivalent (though not necessarily compatible) presentations on Linux systems, including OpenOffice.org Impress, KPresenter, and MagicPoint.

"Run Levels" in Linux are different startup or shutdown settings that can be used at any time to force Linux into a given state using the "init" command.

Level 0 forces a total system shutdown.

Level 1 switches to "maintanance mode" and only allows the system administrator to log in. This is about the same as Windows "safe mode with command prompt".

Levels 2 and 5 can be defined differently, depending on what version of Linux you are using. Typically, one of these is set to start the graphical user interface, another to start only the command line, and so on. The exact results, again, always depends on what version of Linux is used.

Level 6 forces the system to reboot.

It should be helpful to note that runlevels are not in every Linux system. Systemd-based setups do not have runlevels. The closest they have are "targets," though these are not completely analogous to runlevels.

Gentoo Linux can be challenging to install. There are several ways to receive guidance on the best way to install it. There are instructions on the Gentoo website. The Wiki How website would also be helpful.

By default it listens on SMTP port 25

The official name of the Linux mascot is "Tux". The name supposedly was the result of on-line discussions on what to name the Penguin (which had already been established as the default logo for LINUX because Linus Torvalds "like[s] penguins")

As far as we know, the post establishing the name came from James Hughes:

(T)orvolds (U)ni(X) --> TUX!

In all likelihood it stuck because it was a clever linking of the elements of LINUX to the appearance of a penguin, e.g. they look a bit like they are wearing a black tuxedo with a white shirt.

The apache http server

It's referred to as the WINDOWS key and is usually represented by the Windows logo from Microsoft and is usually located in the real estate between CTRL and ALT.

Android is based on the Linux Kernel. A kernel is a program that handles I/O and basically all the hardware stuff. So Android OS is device specific. (However there are some linux distributions which are device specific and you have to compile the kernel yourself.) That's why you can't install KitKat for Sony on an HTC device. You have to make it (compile) to suit your device's hardware specs.

An X server is a program in the X Window Systemthat runs on local machines (i.e., the computers used directly by users) and handles all access to the graphics cards, display screens and input devices (typically a keyboard and mouse) on those computers.

The GNU project develops programs and utilities for an as yet rudimentary operating system known as "GNU." Since the programs are open-source, they have been adapted to work using the Linux kernel as well. Other than using its programs, there is no direct relationship.

In Linux, command typed at a command prompt displays a list of commands that would likely contain the command you desire. For example, to find all of the commands that have word flush in their name or descriptions type the following: man -k flush

You can get a list of all the files in the current directory with the "ls -a" command.

In Windows, files have an owner (usually the creator), but not a group, to which they 'belong'. - and the owner isn't really important in determining access rights. Files either have an explicit list of people and groups or inherit it from a parent directory. These lists specify individual users and groups (in a list) who have access to the directory/file/subdirectories, and the specific rights granted to each item.

In Unix/Linux, each file and directory belongs to a specific user AND group - for example, configuration files may belong to user root and a group set up for administrators (typically called 'wheel'). Instead of having a list of people who can/cannot access the file, you simply specify read, write and execute privileges for the owner and group the file belongs to, and then anyone else.

In Windows, if you have a configuration file, the owner doesn't matter. Instead you set the ACL to include any Administrators you want to access the file, as well as any other users that may need to read it, including the program it configures.

In Linux, you'd perhaps set the same configuration file to belong to the root user, and the group to which the configured program runs in, and everyone to no rights at all - so only root and the program can read it. Or you could set the owner to the user the program runs under and the group that the Administrators belong to, so the program can read it and so that Administrators et.al. can change the file, but keep everyone set to no rights to keep the configuration secure.

They are two different ways of accomplishing security, each with their own configuration peculiarities and performance issues.

There is no "default" shell. Different distros are free to pick whatever shell they want. The most commonly used as the main shell is Bash, but other shells, including the Korn shell, C shell, Friendly Interactive Shell, or Almquist shell are also available. Many distros also use a variant of the Almquist shell provided by BusyBox in their initial ramdisks before switching to the real root and launching the main shell.

* Most Linux operators are more familiar with the inner workings of their systems than most Windows users, so they are usually more capable of setting up their machines securely.

* Many Windows "features" require execute and other priviledges on the machine. This means that, by default, Windows security is set up to be looser. These priviledges can be taken advantage of by people with malicious intentions against users that have not made adequate security adjustements on their machines.

* Most "hackers" want to get the most bang for their effort. Since Windows is used on far more computers than Linux, they focus their efforts on creating hacks or viruses that effect Windows systems.

The man command of the Linux operating system is the system's documentation pager. Each page argument given to man is normally the name of a program, utility or function. For example, to see the reference manual of the grep program: man grep

syntax:

ls -aF

-a option is for hidden files

-F is for directories and executable files

The answer seems to be "no" - I bought the Lexmark version of this cartridge, and it doesn't work - the chip on it causes the printer to read "invalid cartridge". Some older versions used an additional slot to differentiate between Dell and Lexmark, but they've now gone down the hardware route and there doesn't seem to be a way around it.

That means you have to order from Dell, and I need to print today. $50 from Office Depot down the drain and no other option. I'm selling this POS printer and buying one from a company that doesn't so blatantly screw its customers.
