BD

I'm not goin to write about Business Delegate pattern... by BD here I meant the NeXt Generation optical disc format : Blu-ray Disc.
If you are having 4 GB or 5 GB HD throw it off... switch to Blu-ray Disc. A single layer Blu-Ray disc can hold 25 GB.

Blu-ray Disc format was developed by BD Association which includes all major consumer elctronics, PC and media manufactures. Hopefully BD will replace DVD in a short time.

IPng

IPng - IP Next Generation is the next version of the network layer protocol - IP. Officially named as IPv6 - Internet Protocol Version 6 was invented in 1994(Still called next generation!!!). Previous version of IP is v4 (IPv4). Primary change from IPv6 to IPv4 is IPv6 addresses are 128 bits long while IPv4's is 32 bits. This over comes the main draw back of IPv4 : limited number of available IP addresses. IPv4 provides around 4 Billion (2^32) addresses where as IPV6 enables, 2^128 IP addresses.
