Register bits are represened in hexadecimal digits....

Cisco register bits are used to control the booting function
of the devices....like we have 4 different types of booting
options available for the cisco devices...
1. ROMMON mode (0x2100)- is used for the normal trouble
shooting like password recovery....
2. BOOTROM (RXBOOT) (0x2101)- is used for the disaster
recovery like IOS recovery....
3. Normal Mode (0x2102)- is the normal booting sequence used
by any device to function properly.
4. Setup mode (0x2142)- is used when the device is not
having any configuration setting in it(deleted) or the
device is brand-new.

difference b/w SUS and WSUS

SUS did a great job of keeping Windows up to date, but WUS
will be able to update other products such as Microsoft
Office, Exchange Server, and ISA Server. Eventually, WUS
will be able to keep all current Microsoft server products
up to date
