![3 Now Configure the routers
By switching on the router enter into its config mode to configure the routers by following
commands:
Simulation Commands:
Double click on router
Select CLI
Command page opened
Then select
Continue with configuration dialog? [yes/no]: no
Then enable router, writing en
Then configure router by writing config t, as shown below
Router# config t
Router# int fa0/0
Router(config‐if)#ip address 192.168.1.1 255.255.255.0
Router(config‐if)#no shut
Router2(config‐if)#int fa0/1
Router(config‐if)#ip address 10.10.10.1 255.0.0.0.0
Router(config‐if)#no shut
Then exit
Router(config‐if)#exit](https://image.slidesharecdn.com/practical4cse307ppt-230414110221-87a5ecdd/85/Practical_4_cse307_ppt-ppt-10-320.jpg)

- 2. keywords Communication Mode Transmission mode refers to the mechanism of transferring of data between two devices connected over a network. Synchronization Synchronous data transmission is a data transfer method in which a continuous stream of data signals is accompanied by timing signals (generated by an electronic clock) to ensure that the transmitter and the receiver are in step (synchronized) with one another. Carrier wave In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an information-bearing signal for the purpose of conveying information. This carrier wave usually has a much higher frequency than the input signal does. self synchronizing A self synchronizing digital signal includes timing information in the data being transmitted. This can be achieved if there are transitions in the signal that alert the receiver to the beginning, middle or end of the pulse.

- 7. IP Address Format IPv4 (Internet Protocol version 4) IPv6 (Internet Protocol version 6) IPv4 IPv4 is version 4 of IP. It is a current version and the most commonly used IP address. It is a 32-bit address written in four numbers separated by a dot (.), i.e., periods. This address is unique for each device. For example, 66.94.29.13
- 8. Classful Addressing The 32 bit IP address is divided into five sub-classes. These are: Class A Class B Class C Class D Class E Each of these classes has a valid range of IP addresses. Classes D and E are reserved for multicast and experimental purposes respectively. The order of bits in the first octet determine the classes of IP address.

- 11. Switch A switch is a multicast networking device that works under the Datalink layer of the OSI model and connects a bunch of computers or devices in a network. It’s mainly used to send a private message and it does not waste data. A switch can easily identify which device is connected to which port by using a MAC address giving it the ability to deliver the message to a particular machine. Advantages of using a Switch •It’s secure since it delivers data to the specified node. •It lowers the chances of frame collisions domains. •It increases the bandwidth in a network. •It increases the number of ports needed to connect the nodes available in a network. •It operates under full-duplex. Disadvantages of using Switches •They are more expensive compared to hubs and other devices used in a network. •To deal with multicast parcels, proper planning is required. •Problems may arise when broadcasting traffic.
- 12. Router A Router is a networking device that operates under the network layer of the OSI model and is used to connect two or more networks. It is a device that establishes a common link between networks to enable data flow between them. Advantages of Routers •With the aid of dynamic routing algorithms, it can choose the best path in the internetwork. •It creates collision domains to reduce network traffic. •It provides connections between different network architectures. Disadvantages of Routers •They are expensive compared to hubs and switches. •They need to analyze data. This makes them slower. •They have low bandwidth because of their dynamic router communication.
- 13. Hub A Hub is a simple and cheap networking device that works under the physical layer of the OSI model and connects a bunch of computers in a Local Area Network(LAN). It is considered less intelligent because it does not filter data and does not know where the data is to be sent. All information sent to a hub is automatically sent to all ports of the devices connected to it. This leads to wastage of bandwidth. Advantages of using hubs •They have the ability to connect to the network using different physical media. •They can be used to increase the network distance. •Hubs are relatively cheap compared to switches and other devices in the network. Disadvantages of using a hub •It increases the chances of collision domains between packets when being transferred from one device to another. •Hubs operate under half-duplex. Only one device can send or receive data at a time •Hubs share data to all the devices in a network thus making the network insecure. •Hubs waste lots of bandwidth when transmitting data.
- 14. Placement Interview Question Switch vs Hub •A Hub is a broadcast device that sends data from one node to all nodes but a Switch is a multicast device that can send data to a particular node. •A Hub supports half-duplex i.e., only one device can send or receive data at a time while a switch supports full-duplex i.e., both devices can send and receive data at the same time. •A switch is located on the second layer of the OSI model while a Hub is located on the first layer.
