有關虛擬console這個"名詞"的問題 - Linux

目前對虛擬console的認知是:
1. linux為了讓多個主控台共用一組螢幕+鍵盤,
而提供了一種叫做"虛擬console"的功能.
2. tty1~tty6是文字介面的虛擬console, tty7則是X window介面的虛擬console
(ref: http://docstore.mik.ua/orelly/unix3/upt/ch23_12.htm)
我的問題是:
根據上述第二點的內容,
是不是linux裡面的console永遠都只能被稱為"虛擬console",
而不能像UNIX那樣有"實體console"呢?
為何要加"虛擬"這個形容詞呢?
如果linux裡面的console真的是只能稱為"虛擬console"的話,
假設我們可以把虛擬console的數量調成只剩一個,
(PS.我才學疏淺, 不確定能否真的只能調到剩下一個虛擬console,
若真的不能調成只剩一個虛擬console,還麻煩請見諒!)
那剩下唯一那個console也要稱為"虛擬console"嗎?
因為在那種情況下,這個環境就等於跟"只有一個console的UNIX機器"一樣了...
也就是只有一個控制介面,和一組鍵盤+銀幕.
這樣的console,感覺不像是"虛擬console"了.
還麻煩請版上各位們指點一下,
謝謝...
