C - What Does That Motherboard Terminology Mean?
One or more interface cables (typically, in relation to a motherboard, includes cables for a floppy drive, hard drive, and CD-ROM drive; may include cables between an internal connector header and a bracket or other opening at the front of rear of the system; may include cables for both IDE/ATAPI and SCSI devices).
Communication Network Riser (CNR):
This is an expansion slot for communications/network riser similar to AMR but also supporting LAN connectivity.
It is a series of two or more metal pins on the motherboard or other PCB; used to attach a cable to indicator lights, switches, and/or other devices in the computer
The term “chipset” (sometimes called core logic) often refers to the two main chips on the motherboard:
the Northbridge and the Southbridge. The Northbridge and Southbridge are sometimes combined. This is called single-chip design.
In motherboards, the “codec” (Compressor-Decompressor or Coder-Decoder) or “audio codec” refers to the combined audio AD/DA (analog to digital/digital to analog) converter, which is a required hardware for most onboard audio solutions.
Complementary Metal-Oxide Semiconductors (CMOS):
In motherboards the CMOS (Complementary Metal-Oxide Semiconductors) refers to the chips that contains the basic start-up information for the BIOS (aka BIOS settings).
CPU Socket, Socket A/478/754/939/940, LGA775:
The CPU socket or slot is the interface of both the processor and the motherboard. The processor’s socket type must match the motherboard’s CPU socket to be installed properly. For example, an LGA775 processor must be installed on an LGA775 motherboard.
