PowerPC Performance Optimization With Enhanced RISC
A by APPLE, IBM and MOTOROLA are the common development of RISC computer architecture, is an open architecture, not limited to the use of the operating system and hardware configuration. POWERPC processor (PROCESSOR) for the reduced instruction set (RISC) architecture, including are: 1. 603E: 32 Weiyuan (BIT), the use of CMOS, 2.5 V (VOLT) internal voltage, 3.3 V input and output voltage, use the 250 MHZ clock, when the operation of electricity consumption is about 3.7 watts (WATT) .2. 604E: 32 Weiyuan (BIT), the core voltage of 1.9 volts, using 0.25 MICRON CMOS process, the cache (CACHE) capacity 603E twice the operating frequency of 166, 180, 200, 225 and 233 MHZ, built-in performance monitoring mechanism .3. 750: 32-bit (BIT), the core voltage of 2.5 volts, using CMOS, built-in L2 cache controller.

PPPoE Ethernet Point to Point Protocol (Point to Point Protocol over Ethernet)
PPPoE is based on two criteria - Ethernet (Ethernet) and to-peer technologies (Point-to-Point) protocol on top of that allows computers and xDSL, cable or wireless broadband connection such as broadband connectivity devices interface to quickly access the Internet.
Most Internet service provider (ISP) and telecommunications companies have switched to support the protocol. PPPoE primarily used in broadband Internet services, but with the original dial-up network infrastructure, integrate with each other, while supporting the existing network services, including identity authentication, secure access and account management.
For the user concerned, PPPoE is easy to use, retaining the Wondows operating system uses a modem (Modem) dial-up connection method does not require cumbersome and complex set of additional procedures.
Ordinary users as long as the PC card installed Ethernet cards, while Internet service providers to apply for broadband services, access to account code and PPPoE software, or set to start Windows XP built-in PPPoE connectivity, you can dial-up to obtain dynamic IP, enjoy anywhere on the Web.

PPTP Point-to-Point Tunneling Protocol
A by Microsoft (MICROSOFT) proposed by the IETF protocol adopted (PROTOCOL), allows the Internet between computers (INTERNET) to establish a virtual private network (VPN), to ensure that the information flow on the network security. Cisco ( CISCO) have agreed to L2F and Microsoft (MICROSOFT) the merger of the PPTP specification into L2TP.
