BITS 1313 DATA COMMUNICATION AND NETWORKING

OSI layer model for student : This OSI Layer Model discussion will begin with a Cobham Collage Campus network connecting to their private network's Online Learning System Server via their home network (public IP address) (Private IP Address). Assume that the Cobham College Campus network is attempting to upload a file to the Cobham College Online Learning System. Let's start with the Application Layer, where data transit services such as SMTP, POP3, and others are supplied to the file that a Cobham Collage student wishes to submit into the Cobham Collage Online Learning System platform. The data is transported using the file transfer protocol (FTP) in this situation. On the Presentation Layer, the file will be converted to binary format, and file compression will begin in order to reduce the file's size. A 10MB file, will be compressed down to 5MB, allowing the content to be transferred even faster. Finally, it will encrypt the file delivered by the sender using SSL or ...

  OSI LAYER MODEL The Open Systems Interconnection (OSI) model defines seven levels through which computer systems communicate across a network. It was the first standard model for network communications, and it was adopted in the early 1980s by all major computer and telecommunications corporations. The present Internet is built on the simpler TCP/IP paradigm rather of the more complex OSI model. The OSI 7-layer model, on the other hand, is still extensively used because it helps visualise and understand how networks work, as well as isolate and diagnose networking problems. OSI was introduced in 1983 by representatives from major computer and telecommunications corporations, and it was recognised as a worldwide standard by ISO in 1984. PHYSICAL LAYER The physical layer contributes to the definition of the data connection's electrical and physical requirements. This layer is in charge of preparing physical network devices for data acceptance. It sends single bits from one node to ...

  Hello, this blog is created by group 10 from 2 BITM S1G2 for  BITS 1313 Data Communication and Network.  This group consist of  5 members which are  Umi Masitah, Muhammad Hazim, Norfaezah, Khairul Hakimi and Nur Fatehah.     Here are the members' details :      Name : Umi Masitah binti Kamaludin Matrics Number : B032110369 Name : Muhammad Hazim bin Nasrun Adil Matrics Number : B032110240 Name : Nur Fatehah Saripi Matrics Number : B032110335 Name : Norfaezah binti Mohamad Matrics Number : B032110195 Name : Khairul Hakimi bin Adnan Matrics Number : B032110061

The scenario of this project can be referred to Figure 1.  Figure 1 shows the logical network flow from a home network to Cobham College facilities. In this figure, a Cobham College’s student is trying to access the OnlineLearning system located in the Cobham College network facilities. The student is using her modem to connect to the public network before able to connect to the Cobham College facilities. From the Cobham College network, the data then was forwarded to IT Center where the OnlineLearning System server is located.
