What are the differences between Windows and Linux file systems?
There are several file systems employed by both operating systems, thus you need to be more specific when asking for a comparison. Windows most commonly uses NTFS these days, although older versions used FAT. There are several popular file systems for Linux, depending on usage. The most common is ext3 or ext4, although ext2, ReiserFS, JFS, XFS, and several others all have fairly common usage.
What should be the specification to install Linux on PC?
Whatever you have.
Linux can be run on a wide range of specifications. Some distros, like Damn Small Linux, only require a 486 with 16 MB of RAM, and 50 MB of hard drive space, something you could have had in 1994. Typical requirements are 256 to 5.12 MB of RAM, a Pentium III or better processor, and 2 to 6 GBs of hard drive space

What is the most efficient Linux file system for laptops?
For most laptop users, the choice of file system won't matter. That's because most people aren't using their laptops for high-performance scenarios where they need to squeeze the absolute most out of their disk subsystem for a given use.
I would recommend leaving it to your distribution's default. They would have most likely tested it more with that particular file system, though it doesn't usually make a difference to the OS.
The only special mention is that the Reiser4 FS can do transparent file system compression, meaning your laptop data is theoretically safe with little-to-no effort when properly configured if it were to get lost or stolen.
Lastly, many tech-types are particular to certain file systems. Most hold one close to heart. Almost all 'Linux' file systems in use today are well-tested and should perform well for general workstation tasks.

Can Mac OS X or Linux be used on a bootable floppy or CD?
Linux can be booted from a floppy or a CD, although very few modern distros are actually booted or installed from floppies. Mac OS X cannot be booted or installed from a floppy; the last version of the Mac operating system that could be reasonably booted from a floppy was System 6. Mac OS X versions up to 10.4 could be installed with CDs; 10.5 and later require a DVD.
