2 :: What is MacFUSE?

MacFUSE is software that allows you to write arbitrary file systems as user-space programs. You can think of it as a library for easily developing Mac OS X file systems. Another crude way to look at this would be to think of MacFUSE as something that makes Mac OS X work like a microkernel for the purpose of writing/running file systems. MacFUSE has two major components: an in-kernel loadable file system and a user-space library (libfuse). The in-kernel file system is specific to Mac OS X and is not based on Linux FUSE. (Some of its code is based on the FreeBSD implementation of FUSE.) The user-space library (libfuse), which provides the developer-visible FUSE API, has numerous Mac OS X specific extensions and features.

3 :: How to take screen shots on the Mac?

To take a screen shot with Mac OS X hold down the Command (cmd) key and the shift key and either the number 3 to take a shot of the whole screen or number 4 to change your pointer to cross-hairs that can be dragged across a section of the screen to capture just tat part. With the cmd+shift+4 option you can put your pointer over a window and press the space bar to capture that window,
In the Utilities folder which is in the Applications folder is software called Grab which does the same thing but also allows for a delayed capture which gives you ten seconds to arrange your screen before taking the shot.

4 :: How to transfer files from mac powerbook to external hard drive?

First, make sure that your external hard drive is USB capable. If it uses firewire, then that might be the issue. If it is USB capable, then plug it into the power book. Wait at the most 1 minute for it to recognize the external hard drive. If it does not appear on the screen, you may want to try and plug it in on a second computer. If it doesn't show up on a second computer, the hard drive may have a problem/bug. If it does show up, then drag the selected files onto the hard drive. If it says you can't, then there probably isn't enough room on the hard drive to store the files. That is about all that can be explained to you from the information given.

5 :: How to use Internet Explorer 7 on Mac OS X?

6 :: Where is the print screen key on a Mac?

There is no print screen key for Macs, however, there are several key combinations for taking screenshots based on what you want to do with the screenshot.
I personally use Cmd+Shift+4, and select what I wish to take a picture of, or if i want to take a picture of a window, I press space. This will save the screenshot on your desktop.

7 :: How to delete files in Mac OS X?

9 :: Suppose if you delete something from the registry editor does it uninstall?

Registry is like a database which stores windows information.
all you are seeing in your system is controlled by registry.
registry also stores location of applications and processes. so if you delete an application entry from registry than you cannot see it in Appwiz.cpl.
I suggest don't make changes in registry if you haven't much knowledge about it. It May corrupt your windows.

10 :: When to update mac software to keep files?

On update user files are not effected (mostly). Applications (~/Applications or /Applications) files and user files (~/Library/Application Support) are kept in different locations. Most of the times only application files are updated and only developer decides what should happen with user files. If older user files are not compatible anymore and new version of application can't convert your user files to newer version, configuration files of that application will be damaged and removed. Application will start as first time and reconfiguring will be needed (if required at all). For instance Skype requires login information.
Other files not related with application is touched.

15 :: How to make Eee PC running Linux look like Mac OS X?

The Xandros system does not allow this extent of modification. You would need to install another Linux distribution on the Eee. Two distros that have a GUI similar to that of Mac OS X are gOS and Dreamlinux. gOS is designed for low-powered devices like the Eee, so it should be a good fit. Dreamlinux is not tailored for the Eee, but has low system requirement.

Based on the location of the root bridge, the other switches determine which of their ports has the lowest path cost to the root bridge. These ports are called root ports, and each switch (other than the current root bridge) must have one.

17 :: Tell me what is non designated port in spanning tree protocol?

Non-designated ports have no role to play and hence are put into blocking mode.
If it helps, consider root/designated/non-designated as port roles, and forwarding/blocking as port states. Every bridge has a root port, and every link has a designated port.

21 :: Can you please explain the difference between Mac OS X and Windows?

OS X is a BSD Unix based operating system with a GUI which is more user friendly than Windows for many users. The OS allows for permissions based accounts, and has better access controls to limit the spread of malicious software (yes, there are viruses and proof of concepts which target Apple software), and protects the system folder from write actions unless a user has administrative privileges.
The ease of use is often cited as a primary reason for educational institutions and art related business to defer to Apples.
Windows is prevalent in business environments, and has differing architectures based upon which flavor is installed (there are vast differences between 3.11, 95, 2000, XP, Vista, and 7) and the variations would best be researched on a product information site. Because of the popularity of Windows, malware and viruses are numerous, and an antivirus program is often the bare minimum that a user must use to protect their computing resources and data.
No matter the operating system, a best practice to follow is to always work from a user account with limited privileges and only do upgrades and installs from within the administrative account's workspace.

22 :: Tell me do Macs have USB ports?

Apple's original 1998 iMacs were the first computers to solely use USB ports and the popularity of the computer expanded the market for USB peripherals. USB ports remain a feature of all Macs to this day day.

23 :: What is Mac OS'X?

OSX is a Operating system derived from BSD, and thus unix...
Unbuntu can be skinned to look like and behave like OSX (I did that in about 15 minuets)
OSX in a sense is a Desktop environment, but is very resource intensive in contrast to openbox.
(If you do it right, a computer running Linux and openbox can boot to login in 15 seconds)
(Linux is a derivative of UNIX)
So basically, OSX is a way for you to have your computer do the work you want it to do.
