SDRAM Synchronous DRAM
Synchronous dynamic access memory, only machines (Synchronous DRAM), is a new type of DRAM compared to conventional memory clock speed of many. Because it and the CPU's bus synchronization, and the ability to simultaneously open two memory pages (PAGE), computing speed of up to 133 MHz. Intel's Pentium series produced using 100 and 133MHz, CPU bus, so SDRAM can support, but the future of personal computers may be used up to 200 MHz of the bus, SDRAM is not enough support, and this is why the industry has to develop more high-speed memory, such as RDRAM.

SEC Single Edge Contact / Connector
Intel (INTEL) to improve processor (PROCESSOR) performance, and chip (CHIP) processors designed for the production yield packaging cartridge (CATRIDGE), so that the core processor chip and the L2 cache (CACHE) can be separated from production, and then integrated into a cartridge on. SEC cartridge with a cooling device (THERMAL PLATE), and a line supports the use of DIB structure will enable the L2 cache with the general bus (BUS) separation using a faster clock operation.

Sector Hardware
Sector, disk (DISK) on the minimum access unit, logically speaking, a disk outward from the center of a circle is divided into several tracks (TRACK), each track is further divided into several fan-shaped region, called sectors.

Segment Network
Network (NETWORK) on a section of the computer section all use the same transmission medium (MEDIUM).
