© 2005 Cisco Systems, Inc. All rights reserved. INTRO v Summary Most components of a computer are contained inside the casing and are largely involved with the internal processing of the computer. Those components include the motherboard, CPU, bus, RAM, ROM, power supply, hard drive, and the operating system. The connectors to external components are located either on the side or in the back of a computer and include a serial port, video port, Ethernet port, USB port, keyboard port, and the CD-ROM drive.

The following are commonly used computer measurement terms: bit, byte, kb, KB, kbps, kBps, Mb, MB, Mbps, MBps, Hz, MHz, and GHz. There are many similarities in the characteristics of a PC, a router, and a switch, with some notable differences, such as the lack of a hard drive, keyboard or mouse port, or USB ports in routers and switches, as well as differences in network port functions on all three devices.
