In the meeting room where they were discussing technical issues they debated about whether "machines carry diseases" that can be passed on to other machines and infect them.
Of course we now know it as a "virus" and yes, this scene was right on the money 25 or 30 years before the term became mainstream.
Errors in code were known as "bugs" ever since the early days of the huge mainframe computers. The use of the word "virus" evolved to mean malicious code but was taken from the original "bug" which Crichton probably got the idea from. Another prediction they got spot on is computers that design other computers. There's a scene where the lead scientist mentions that in some cases the robots were designed by computers themselves and nobody really knew how they worked.
