[ PJC] Peripheric56 Moby Thesaurus words for " peripheral": ambient, apparent, beside the point, circling, circumambient, circumferential, circumflex, circumfluent, circumfluous, circumjacent, cortical, delineatory, embracing, encircling, enclosing, encompassing, enfolding, enveloping, environing, epidermic, exomorphic, exterior, external, extrinsic, fringe, in outline, incidental, inessential, irrelevant, minor, neighboring, open, out, outer, outermost, outlined, outlying, outmost, outside, outstanding, outward, outward- facing, perimetric, public, roundabout, secondary, seeming, suburban, superficial, surface, surrounding, tangential, unessential, unimportant, unnecessary, wrapping (Or "peripheral device", "device") Any part of a
computer other than the {CPU} or {working memory},
i.e. {disks}, {keyboards}, {monitors}, {mice}, {printers},
{scanners}, {tape drives}, {microphones}, {speakers},
{cameras}, to list just the less exotic ones.
High speed working {memory}, such as {RAM}, {ROM} or, in the
old days, {core} would not normally be referred to as
peripherals. The more modern term "device" is also more
general in that it is used for things such as a {pseudo-tty},
a {RAM drive}, or a {network adaptor}.
Some argue that, since the advent of the {personal computer},
the {motherboard}, {hard disk}, keyboard, mouse, and monitor
are all parts of the base system, and only use the term
"peripheral" for optional additional components.
