What Makes a
NeXT
computer a NeXT
computer
 |
DMA Architecture.
We've built NeXT
computers to handle even the most
complex tasks
efficiently. Rather than
basing them on traditional PC or
work-
station architectures, we used a DMA
architecture similar to
that of mainframe
computers (which are known for their
superior
system throughput). The result
is that NeXT computers offer
exception-
al system throughput and performance. |
NeXTstep.® NeXTstep is both a devel-
opment environment
and graphical user
interface. As a development environ-
ment,
NeXTstep makes it possible for
people to design graphical user
inter-
face applications more quickly. As a user
interface, NeXTstep
makes it easy for
people to learn to use a NeXT computer. |
UNIX.®
NeXT computers run on the
UNIX operating system, which offers
true
multitasking and powerful net-
working capabilities.
Display
PostScript. NeXT offers a
unified imaging model; that is, we
use
Display PostScript for imaging on
both the screen and the
printer.
Which means that what you see on
the screen is precisely
what you'll get
when you print.
