Yes we can, ambil contoh X server, kenapa dikatakan
'server' walaupun jalan dalam satu 'physical' box?
Padahal jelas X client/server pakai af_unix domain socket untuk
display dan fontserver (kalau dalam satu mesin)....
Apakah term client/server bukan berarti networking kalau
hanya dalam satu box? Apakah local area network bukan
computer network karena 'local'?

Hmmm katakanlah saya punya dua "box" computer:
Peculiar network?
box1 <===> shared fibre channel drive(s) <===> box 2
Obvious network:
box1 <===> NFS/Coda server <===> box2
Apakah anda sudah bisa menarik kesimpulan bahwa sistem pertama
adalah computer network?
