Star and extended star topologies The star topology is the most commonly used physical technology in Ethernets LANS‚ when installed ‚ the star topology resembles spokes I n a bicycle wheel. The star topology is made up of a central connection point that is a device such as a hub‚ switch‚ or router‚ where all the cabling segments meet. Each host in the network is connected to the central devices (switches) with its own cables (we are using Fiber Optic Cable) although a physical star topology costs

allow the center ring to hover over the middle and thus allowing a more accurate of what angles and weights would be needed to determine equilibrium. If the strings had simply been run over the edge of the force table‚ it would have been hard to determine whether or not the center ring was balanced or if it was stuck on the table. 2. Explain why the ring does not accelerate (begin to move from rest) in some configurations even though there are several forces acting upon it. The ring does not accelerate

Logical vs. Physical Network Design The typical Top-Down approach to network design uses a systematic method to plan‚ design‚ and implement a new network. Generally‚ the Top-Down methodology involves analysis of the business requirements and goals‚ development of the logical design based on such goals‚ development of the physical design‚ and a phase for testing‚ optimizing‚ and documenting the network design. This paper focuses on the activities performed to create a logical design of a network

Process management on Windows is guided by the user ID. When a user logs on they are given a token that includes their information and preferences and what files and programs they have access to‚ this is known as a security ID. Windows can then determine how to process user commands. Windows process management focuses on how processes are named
