How is Linux different from Windows?

Q. I saw a picture of the Linux desktop and the interface seemed almost identical to windows.

A. In Linux, the core operating system and the window system are separate.

Linux will run happily without the window system, and servers typically do.

The lower layer of the window system is X. This allows the interface and/or windows to be displayed across a network. The higher level part of the the window system is the window manager, and there are many choices for window managers. Different ones look, work and feel different.

In windows, you get what you get. No options, no default over-the-network functionality.

The OS kernel in Linux implements a clear separation of power between users, services and kernel. This clean(er) design leads to Linux tending to be more secure.

There is a high level of isolation between programs. One program crashing will not bring the rest of the system down. Windows doesn't bear up nearly so well.

Unlike windows, Linux tends not to slow down for no apparent reason after a year of use.

Linux is open and free, you can copy, modify and share it. Windows isn't.

Linux comes with bucket loads of application software of all types. Windows doesn't.

Linux usually comes with the development libraries, tools and compilers out of the box, so you can start developing. Windows doesn't and the tools costs a lot.

Linux comes with a number of powerful command line tools. If you want to bypass the window system, you can. You can administer, configure and use the system from the command line if you with. In windows, you can't.

Linux is not one product. There are many distributions packing together the kernel, applications and an installer. They differ in focus and approach. Some aimed at small size and efficiency, some aimed at desktop use, some aimed at servers etc.

Is there a remote support client that supports linux?
Q. My primary computer is my Macbook pro (OSX), and I need to access my Linux Desktop. I used Teamviewer before, when my Desktop ran Xp, but i changed to Ubuntu. Is there any other reliable (preferably free) program that can fill in for this?

A. You want to take a look at VNC {Virtual Network Computing}, which is a protocol that allows a desktop to be viewed & remotely controlled over the internet. It is available in free Open Source versions as well as some that are not free.

From your question it sounds like you want to set up the VNC server on the system running Ubuntu and use a VCN client on your Macbook to interact with it.

How to get wireless Internet on Linux ?
Q. So I just installed Linux and erased windows vista and all my files with it. Now I'm at my linux desktop and can't connect to my wifi network. When I go to the networks icon over the wireless option it cant be selected and says "device not ready (firmware missing). I've looked through the software center for drivers but I can't install them because the only button says "use this source" and when clicked does nothing.
So if someone could help me get on the Internet on it.

A. Missing firmware is typical of broadcom 43XX chipsets, but there are ways to get it.
