Token Ring network technology
This technology can be described as the originator of local area network LAN. As early as before the development of the Internet boom, IBM in 1985, namely, Token Ring technology, to connect different offices or campus computer workstations, printers, and servers.
Token-ring networking can be a result of more effective control of the flow of information within the local area network, but this technology can complement the weaknesses of bus architecture, a substantial increase in the efficiency and stability of the local area network, it officially became a standard LAN-Based 1.

Topology Network
Local area network (LAN) or communication devices each node (NODE) physical and logical arrangement, the main are the following: 1. BUS: all the nodes connected to a transmission medium (MEDIUM) on the .2. RING: Each there is a logical node above and below the nodes, all nodes form a ring .3. STAR: All nodes use independent media (MEDIUM) connected to a HUB.

Touchpad Hardwares
A pressure sensitive pointing device (POINTING DEVICE), typically used in portable computers to replace the mouse (MOUSE).

TPC-C
The most frequently cited the server industry server performance test data. TPC (Transaction Processing Performance Council) is a city located in San Jose, California non-profit organization dedicated to the implementation of the commercial load benchmark tests (benchmarks), and performance data released to the industry.
TPC's benchmark test is a computer database of manufacturers and vendors display the most frequently brought their own performance data. TPC At present there are two main categories of commercial software testing, one TPC-C, the other is the TPC-D; the former to support the business operations of software-based, while the latter is to support business analysis software. A TPC-C online transaction processing (OLTP) benchmark test, simulated warehouse control systems, addressing issues such as orders or track inventory such work. TPC-D is a representative of decision support applications (must be applied to the complexity of the database retrieval, such as data mining) of the test data. TPC-C and TPC-D each representing one of two completely different applications. TPC-C test in the past has always been a UNIX server (using a RISC processor), the world, but in recent years has gradually been the next generation of Windows servers with Intel processors by the invasion.
