Hierarchy and Interconnectivity

-

Hierarchy 
  • Hierarchy is the degree of concentration of networks or traffic flows at interconnection points with in the network.

Inter-connectivity
  • It provides mechanism to achieve performance with in a hierarchical structure.
  • The dynamic between hierarchy and inter-connectivity is perhaps one of the most fundamental trade-offs in the network architecture and design.
  •  Hierarchy provides separation of network into segments. These segments may be separate smaller networks or subnets or broadcast domains.
  • When the amount of traffic in the network grows beyond the amount of network or when interaction between devices on the network result is congestion.

A 32-bit microprocessor introduced by Intel in 1993. It contains 3.3 million transistors. Since 1993, Intel has developed the Pentium III and more recently the Pentium 4 microprocessors.   Pentium III Pentium III Mainboard Layout Intel builds on the technology it developed with the Pentium II microprocessors.  The Pentium III processor comes with a Synchronized Dynamic Random Access Memory (SDRAM), allowing for an extremely fast transfer of data between the microprocessor and the memory. 70 new instructions, called Streaming SIMD Extensions, enhance multimedia and 3D performance.  Launched February 1999 - Available in speed levels of 450, 500, 550, and 600MHz. 32KB of Level 1 Cache (operating at CPU's full core speed). 512KB of Level 2 Cache (operating at ½ of CPU's core speed). 100 MHz bus speed. The branch prediction/recovery pipeline was doubled to include 10-stages from the P-II.   Pentium IV The next generation of microprocessors from Intel. Pe
