1. Access layer is to provide a means of connecting devices to the network and controlling which devices are allowed to communicate on the network. 2. The distribution layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs (VLANs) defined at the access layer. 3. The core layer of the hierarchical design is the high-speed backbone of the internetwork. The core layer is critical for interconnectivity between

single device or cable failure will not bring down the network Weakness If the centralize device fails the entire system is affected Bus Bus is the simplest network topology. All computers are connected to a single cable that makes a connecting Ethernet. Computers decide when network is not busy and communicates data as needed. Bus computers listen to transmissions from other computers and do not forward or echo transmissions to other computers Weakness Limited cable length and number of stations

Matthew Anderson NT1310 October 1‚ 2014 Unit 3 Assignment 1 “A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu‚ 2013). There are several common instances of the bus architecture‚ including one in the motherboard of most computers. Bus networks may be the simplest way to connect multiple clients even though many may have problems. When two clients want to transmit at the same time on the same bus‚ this may cause

Architecting the Ethernet and Hash Tables Using SABER A BSTRACT Efficient algorithms and compilers have garnered tremendous interest from both experts and hackers worldwide in the last several years. Given the current status of virtual algorithms‚ steganographers obviously desire the analysis of public-private key pairs‚ which embodies the natural principles of hardware and architecture. We demonstrate not only that red-black trees and fiber-optic cables can collude to accomplish this goal‚ but that

The Commodore VIC-20 used a port expander to allow more than one Cartridge to be connected to the single ROM cartridge port. A port expander can be any device to which one existing or onboard port becomes two or more. E.G. a KVM switch or a USB hub. One advantage is the ability
