Why “motherboard” is used to refer to main board of computer ?

It’s called a motherboard because it is the main circuit board in the computer, and it can be extended by plugging other circuit boards into it. These extensions are called daughter boards. Wikipedia suggests that historically a “mainboard” was not extensible in this way, hence the need for different terminology. Many computer terms use human or biological words as metaphors:

  • Master/Slave (controller and devices)
  • Male/Female (plugs and ports)
  • Mouse
  • Peers
  • Server/Client
so next time interviewer asks this question, you’ve a clear answer.
