Solaris OS
By Sun Microsystems (SUN) developed by the UNIX operating environment, including SUNOS operating system (OS) and the graphical user interface (GUI), support for symmetric multi-processor (SMP).

SONET (Synchronous Optical Network)
SONET is a Bellcore developed in 1985 to STM (Synchronous Transfer Mode) architecture on the optical media, a network equipment, this network was established in ANSI T1.102, T1.105, T1.106, T1X1.5, etc. standard. SONET can provide more than a few hundred MB of bandwidth, especially for as telecommunications systems, the Internet backbone (backbone), currently the major goal of the NII is to SONET as the Internet's main trunk line in Taiwan.
SONET is the transmission rate of STS-1 (51.84 Mbps, the data can be sent approximately equal to T3) for the multiple, such as a SONET transmission rate of STS-12, on behalf of its approximately up to 622.08 Mbps rate (excluding logistical channel , error checking codes, control information, the user can actually use about 594.432 Mbps). At present the highest practical standard rate STS-192, approximately 9,953.28 Mbps, when the SONET signal to be transmitted when a smaller bandwidth (less than 51.84 Mbps), using a virtual branch termed (Virtual Tributary) signals, which can be removed from the fiber backbone which part of the bandwidth available to the FDDI, SMDS and other Internet usage.
SONET fiber optic transmission of each frame size of 810 bytes, while the basic clock for the transmission of 8 KHz, so the basic transmission capacity of 8 × 810 × 8000 = 51.84 Mbps, we will develop this rate for the optical fiber transmission rate of the basic unit of STS-1, also known as OC-1.
Optical fiber system in the world apart from North America, SONET specification, the European system uses the SDH-based, and its basic transmission rate of STM-1 (155.52 Mbps), which is equivalent to STS-3/OC-3.

South Bridge Chip
Control processor on the motherboard to communicate with all the other peripheral logic chip chipset called the group (usually referred to as chip group), logic chipset northbridge and southbridge are generally divided into two, which one closest to the processor chip for the Northbridge , remote, compared with South Bridge chips.
South Bridge is responsible for communication between the processor and peripheral, including PCI interface, hard disk and CD-ROM drive IDE controller, USB controller, also like a floppy disk, keyboard, mouse control is also included here. With technological upgrade, South Bridge chips are more and more integrated features, such as chipset vendors often sound, networking and other functions directly into the South Bridge.
The following diagram (VIA P4X333) of the motherboard design diagram as an example: the diagram below shall be part of a blue background Southbridge chip, the top blue box is the North Bridge, at the top of the orange box is a Pentium 4 processor.
