Labels:text | screenshot | font | document | number OCR: Options For PC-UNIX Resource Sharing FIGURE 1 PC TCP/IP PC clients use TCP/IP protocols exclusively, replacing the existing PC LAN servers with UNIX servers. PC Dual-stack PC clients run multiple network protocols to access both UNIX (TCP/IP) and the local PC LAN. LAN Server Gateway PC LAN servers add TCP/IP stacks and run gateway software to convert LAN packets to TCP/IP. UNIX PC Server UNIX servers add support for PC networking protocols and software to emulate PC networking systems. Tunneling Encapsulate one network protocol in another (NetBIOS over TCP/IP or NetWare IP are examples). Custom Add special network protocols on both PC and UNIX machines (Locus's PC Interface, for example). Emulation Make popular DOS and Macintosh applications accessible on UNIX workstations using software and/or hardware emulators.
