Short for Direct Cable Connection, a Windows 95 feature that enables two computers to be connected via a serial or parallel cable. Once connected, the two computers function as if they were on a local-area network (LAN). Either computer can access files on the other computer. But because DCC does not require network interface cards (NICs), it is less expensive and simpler. The limitations are that it can connect only two PCs, and the data transfer rate is slower than with a true LAN.

Traditional COM components can only perform interprocess communication across process boundaries on the same machine. DCOM uses the RPC mechanism to transparently send and receive information between COM components (i.e., clients and […]
Short for Discrete Cosine Transform, a technique for representing waveform data as a weighted sum of cosines. DCT is commonly used for data compression, as in JPEG. This usage of DCT results in lossy compression. DCT itself does not lose data; rather, data compression technologies that rely on DCT approximate some of the coefficients to […]
