case 2-1
Since the most important thing that I care about in this network is speed, it is better to use a Switch as an interconnect device, because it has dedicated bandwidth in which all computer have the same amount of bandwidth as the overall bandwidth, unlike hubs in which the bandwidth is shared.
case 2-2
We can use a router, that will work as a messenger that allow communication between LANs, yet it won't forward the message.
case 2-3
1. logical topology is how devices appear to connect with the user, while physical topology is how these devices are connected between one another ( the wires and cables ).
2. bus is a network architecture, it is one type of topology in which the clients are connected by a line cable.
3. star topology is the most common topology, it has a central switch or hub that is connected to the other CPUs.
4. ring topology is a type of topology in which the all devices are connected to one another by a cable that goes in a circle just like a ring.
5. Ethernet and CSMA/CD: Ethernet is a computer network technology that is used for Local Area Networks. / it is a Media Access Control method that use a carrier sense schema, and transmitting data and except it if it was a signal, and refuse it if it was a frame.
half duplex only
bandwidth sharing
then transmits signals
then regenrates signal
then Clean signals
first recieve signals
