The term postmodernism has been applied both to the era following modernity, and to a host of movements within that era (mainly in art, music, and literature) that reacted against tendencies in modernism.
A CSU/DSU (Channel Service Unit/Data Service Unit) is a hardware device about the size of an external modem that converts a digital data frame from the communications technology used on a local area network (LAN) into a frame appropriate to a wide-area network (WAN) and vice versa.he Data Service Unit (DSU) manages line control, and converts input and output between RS-232C, RS-449, or V.xx frames from the LAN and the time-division multiplexed (TDM) DSX frames on the T-1 line. The DSU manages timing errors and signal regeneration.
The effect is similar to the tent filters AMD used in its old CFAA scheme or, more recently, to the kernel employed by Nvidia's own TXAA technique. One of the more intriguing capabilities Nvidia introduced with the GeForce GTX 970 and 980 is a feature called Dynamic Super Resolution, or DSR, for short. DSR is a way for a fast GPU to offer improved image quality on a lower-resolution display. Nvidia bills it as a means of getting 4K quality on a 2K display.
