Data Communication And Networking

 

  1.     1.    Go to Network & Internet settings by going to the Settings or click the wifi icon on the bottom right of your screen. 2.        Click on Change adapter options 3.        Open the properties of your fully connected Internet by simply right-click on Wi-Fi and choose Properties. 4.        A new window will popped up. Find and double-click on Internet Protocol Version 4 (TCP/IPv4) to set up the IP address. 5.        Click on the “Use the following IP address“ option. 6.        Input the IP address obtained from the calculations. 7.        Use the same IP address but different number on the 4 th octet for Default Gateway . 8.        For the Preferred DNS Server, insert the same IP address 192.168.80.5. 9.        As for the Alternative DNS Server, we can use Google DNS server which is 8.8.8.8 just in case the computer cannot reach the Preferred DNS Server. .         10.   Click Ok and everything should be good to go. The IP a

  In this section, you are expecting to show the calculation on how to identify the IP address that was assigned for the ULearn System Server based on the information given in the project scenario. Explain the concept and show the calculation to identify the IP address.   The answer:   For Ulearn System Server Network, the IP address scheme for that system is 192.168.0.0/16 . This is Class C private addressing. The default subnet mask is 255.255.255.0 .   Because it has 30 different departments to fulfill the requirement of 30 subnets. So, we need to borrow bits from the host to provide the number of subnets. In this case, it borrow 5 bits from the host.   2 n = 32 networks 2 n = 2 5     n = 5 , where n = borrowed bit   This illustration uses the network formula to find subnets that are closest to 30. Image 1 : Network formula   Since it 5 borrowed bit from the host, the new IP address scheme is 192.168.0.0/21 . So, the new subnet mask is 255.255.248.0/21 .

  There are few network components that involved  throug hout the communication. First, message. Message is the information or data to be sent by sender or received by receiver.  For examples, text, numbers, pictures, audio, and video. Next, the sender which is the device that sends data whereas the receiver is the device that receives the data. In this case, the Lecturer’s Computer is the Sender and the ULearn System Server is the receiver. The transmission medium is the physical path between the sender and the receiver. For examples, twisted-pair wire, fiber-optic cable, and radio waves. A protocol is a set of rules that govern data communications. It represents an agreement between the communicating devices. Without a protocol, two devices may be connected but not communicating. In this case, the HTTP/S are the protocols that are used to perform the lecturer activities to access the ULearn System. The OSI Model                OSI stands for  Open System Interconnection. It is a ref
