The de facto standard application program interface (API) for TCP/IP applications is the "sockets" interface. Although this API was developed for ___71___ in the early 1980s. it has also been implemented on a wide variety of non-Unix systems. TCP/IP ___72___ written using the sockets API have in the past enjoyed a high degree of portability and we would like the same ___73___ with IPv6 applications. But changes are required to the sockets API to support IPv6 and this memo describes thesechanges. These include a new socket address structure to carry IPv6 ___74___. new address conversion functions, and some new socket options. These extensions are designed to provide Access tothe basic IPv6 features required by TCP and UDP applications, including multicasting, while introducing a minimum of change into the system and providing complete ___75___ for existing IPv4 applications.

The World Health Organization says lifestyle factors are at the root of the non-communicable disease crisis, which is responsible for millions of premature deaths every year. WHO is calling for global action to combat this epidemic.
The World Health Organization breaks a common misperception. It says non-communicable diseases or NCDs do not mainly afflict affluent people. On the contrary, it says 80 percent of all NCDs occur in lowand middle-income countries.
WHO says non-communicable diseases are preventable. It reports up to 80 percent of heart disease, stroke, and type 2 diabetes and more than one-third of cancers could be prevented by eliminating the major risk factors. These include tobacco use, unhealthy diet, physical inactivity and the harmful use of alcohol.
