1. We can check wether OS is 32 bit or 64 bit with command
uname -a
Linux gaylord.stata.com 2.6.11-1.27_FC3 #1 Tue May 17
20:24:57 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
2.Dont know...
3. Logical block size is the size of the blocks that the
system kernel uses to read or write files. The logical
block size is usually different from the physical block
size, which is the size of the smallest block that the disk
controller can read or write, usually 512 bytes.
To Find out Physical Block Size
dumpe2fs <some device> | grep -i 'Block size'
4. Daemon at NFS Server: portmap,NFSD,rpc.mountd
Clinet End : rpc.mountd
5. showmount -e server name
6. inode contains all information about file and
directory
