+After entering the ''bootm'' command the kernel starts executing from RAM.  The kernel reads the '''bootargs''' argument that was passed as an environment variable earlier.  Bootargs describe the location of the root filesystem.  Reading this information uImage mounts the RootFS and runs /sbin/init (which typically shows you a login prompt).
 Sample rootFS present as download above is configured for following user and password
 user:'''hawk'''
 password:'''password'''

-A Desktop system needs kernel and various application for it to be useful , Similar way embedded devices too
+A Desktop system needs kernel and various application for it to be useful.  Similarly, embedded devices also need a Kernel that manages/allocates resources & Schedule task & Set of Applications to perform user task.
-needs a Kernel that manages/allocates resources & Schedule task & Set of Applications to perform user task.
 The components here are:
-*'''uImage''' :- uImage is a Linux Kernel (2.6.x) that Bootloader(Uboot) Loads which then finally mounts the (RootFS)Filesytem.The filesystem can be either on SD Card / USB Drive or on Another Network PC through NFS(Network File System) Protocol.

 This is similar to Vmlinuz (Linux Kernel that grub loads) that exists in Normal Desktop Environment usually in /boot folder.

 Filesystem is also known as Root Filesystem ,It basically contains all the application  (ls,cat,vi etc ),directory structure
 /dev, /proc, /bin, /etc, /lib, /usr, /tmp & necessary scripts (rc, inittab, fstab etc).
