Glossary
Alias
Alias means “other”, “else” and “also known as”. An alias is
often a short, catchy substitute for a long, complicated string
of characters, for example, the actual name of the user
J.Smith@my-internet provider.com in place of the string
030123456@my-internet provider.com. Here the name
“J.Smith” functions as an alias for “030123456”.
Cache
A cache is a memory between slow and fast units, in which
frequently requested data are stored. A cache is used to re-
duce access times.
KEN!'s cache saves the last Internet sites visited in its memo-
ry, as long as the settings of these Internet sites permit stor-
age. When a user requests a site which has already been vis-
ited, this site is provided quickly and economically from the
cache, without having to establish a new connection to the
Internet.
As opposed to off-line browsers, only pages for which stor-
age is permitted are saved in the cache.
CAPI (COMMON ISDN API)
CAPI is a standardized software interface which allows appli-
cations easy access to ISDN adapters at basic and primary
rate accesses. Applications designed for this standardized
interface use uniformly defined mechanisms for communica-
tion over ISDN connections and need not be adapted for var-
ious manufacturers' hardware. This makes CAPI applications
independent of any future hardware extensions or changes.
CAPI makes such changes transparent to the applications.
CAPI comprises an abstract definition of ISDN services, inde-
pendent of the underlying telephone network and the adapt-
ers used to connect to ISDN. It provides an interface easy for
applications to use an thus affords uniform access options
