Recent advances in computer technology make networking an essential skill for the technical communicator. Particularly, the development of local, national, and international computer networks has created a collaborative writing environment. At the heart of the Internet network is the UNIX operating system. The open architecture of UNIX makes it a superior tool for collaborative writing, in the classroom, across the campus, or internationally. Central to the open system is UNIX's mode of allowing users to set file access permissions, restricting some files while allowing others to be open to the public.
