Notebook computer

A portable computer about the size of a standard ring binder notebook. Original laptop computers were about the size of a briefcase. Notebook computers later emerged that could be carried inside a briefcase. Next, sub-notebook computers were introduced that could be carried inside a suit pocket, although the most popular models presently are notebook size portables. Multimedia versions are slightly larger and heavier. Although notebook computers do not have expansion slots for hardware modifications, SCSI, Ethernet, ISBN, video caputure, and other hardware options are available on PCMCI cards. Also, docking stations allow notebook computers to have most of the features of desktop computers, including expansion slots. (See also Docking station, PDA, and PCMCIA)
