Week 1 Guided Practice 2 - Set up Physical Network OL

An entry in the switching table of a virtual-circuit network is normally created during the setup phase and deleted during the teardown phase. In other words, the entries in this type of network reflect the current connections, the activity in the network. In contrast, the entries in a routing table of a datagram network do not depend on the current connections; they show the configuration of the network and how any packet should be routed to a final destination. The entries may remain the same even if there is no activity in the network. The routing tables, however, are updated if there are changes in the network. Can you explain the reason for these two different characteristics? Can we say that a virtual-circuit is a connection oriented network and a datagram network is a connectionless network because of the above characteristics?

Coaxial cable has been around since local area networking was in its invented. The original designers of Ethernet picked coaxial cable as their "ether" because the coaxial cable is well it has high bandwidth capabilities and low and is easy to install. Coaxial cables are identified by their RG standard. Coaxial cable can have a or stranded core and impedance of 50, 75, or 92 ohms. The Coaxial has wire that carries the signal surrounded by a layer of and another concentric ; both the shield and the inner conductor run along the same axis. The shield also serves as a ground and should be grounded to be effective. Coaxial cable is still widely used for video applications; in fact, its use is increasing due to the greater demand for However, it is not recommended for data installations and is not recognized by the Standard for such.

A network's topology must be specified in five separate ways. Which of the two do you think is the more dependable?

Netwokrking Routing Analysis  1. Looking at Figure below, enumerate the paths from y to u that do not containany loops. There are many. 2. Repeat Problem 1 for paths from x to z, z to u, and z to w

There are three layers in the hierarchical design of Ethernet networks. With the aid of a diagram, briefly explain these layers.

What type of diagram shows a graphical representation of a network’s wired infrastructure? a. Rack diagram b. Wiring schematic c. Network map d. Network topology

There are three layers in the hierarchical design of Ethernet networks.With the aid of a diagram, briefly explain these layers?

ILVER KNIGHT’S HOTEL (Backbone Network Related question)   The Silver Knight’s Hotel is a luxury hotel that whose guests are mostly business travelers.  To improve its quality of service, it was decided to install network connections in each of its 50 guest rooms and 5 meeting rooms. All guests and employee should have connection the internet as well.   There are three sections (two adjunct buildings) in Silver Knight’s Hotel site;   Section 1:  50 guest rooms (one computer connection in each room)   Section 2:  5 meeting rooms with 10 computers with one printer in each. There will be printer sever for meeting rooms room. 5 LANs   Section 3:  Office ( The management  ) one LAN with, 5 desktop computers, Print sever, Mail server , Web Server and Printer. No Wi-Fi.    Your task is to design the network to connect the all three networks together and to the internet.  A backbone network diagram to connect all computers in three sites and connect them all to the internet.   Clearly…
