A stock PC-9821 builds on ideas seen in the PC-9800 series, or more specifically ideas in use in late 1992, primarily the 80386 variants which prior to the PC-9821's introduction, stood as NEC's high-end consumer computers. At this point it becomes difficult to define "standards" for NEC computers as much of the components were interchangable, though most PC-9821 software was designed with this setup in mind - the inclusion of two 3½-inch floppy disk drives and a CD-ROM drive (features subsequently removed or replaced in future "budget" models).
The PC-9821's defining feature is its graphics; the PC-9821 features a 600x480 (or 600x400) screen with 256 colors, something the PC-9801 models can't do. The the exception is the PC-98GS, which is the predecessor the 98 Multi line.
(It's as if I don't know what I'm typing, and that NEC Retro could really use some more volunteers with a more concrete understanding of what's going on.)
Two variants of the original PC-9821 were released concurrently, the S1 and S2, the latter of which which adds a 40MB harddrive.
