I read in another resource on freebsd.org that the first protocol suite was implemented in 4.3 BSD using Xerox Network suite. This was done in order to connect isolated machines that couldn't communicate over networks using TCP/IP. Why was there such an issue for connectivity? TCP/IP seems to be the main component in how things communicate today (with some enhancements)j.

Well, for two computers to communicate with one another, an agreed-upon standard (protocol) is necessary. In the early days there were various ideas about what information needed to be sent across the wire, in what order. The BSD unix operating system proposed some ideas for this, which I believe formed the first version of TCP/IP. Eventually more groups using ARPANET (the predecessor to the Internet) also implemented TCP/IP in their work, and it became a standard.
