SUBNETTING CALCULATION

What is a subnet? A subnet, or subnetwork, is a network inside a network. Subnets make networks more efficient. Through subnetting, network traffic can travel a shorter distance without passing through unnecessary routers to reach its destination. Subnetting allows creating smaller network (sub networks or subnets) inside a large network by borrowing bits from the Host ID portion of the address. The borrowed bits can be used to create additional networks, resulting in smaller-sized networks. This can help to reduce : Wastage Improve network performance Effective isolation Easier administration In this section, you are expecting to show the calculation on how to identify the IP address that was assigned for the OnlineLearning System Server based on the information given in the project scenario. Explain the concept and show the calculation to identify the IP address. Step 1 is to propose a private addressing system for usage in the Cobham Collage campus network. In term of private ad...

TCP/IP CONFIGURATION MANUAL

  TCP/IP CONFIGURATION MANUAL In this section, we are assumed to have correctly identified the IP address for the Online Learning System Server. Therefore, we need to produce a manual on how to configure the IP address on the server. So, we can use any operating system to demonstrate this task. The explanation was included the screenshot and appropriate explanation. TUTORIAL FOR CONFIGURING TCP/IP IN WINDOWS 11 1. Press windows button and search Control Panel and click . 👇 2. In Control Panel, we need to click the Network and Internet to configure TCP/IP. 👇 3. Then, click Network and Sharing Center . 👇 4. After that, on the left side of windows we need to click on Change adapter settings . 👇 5. Right click on the Wi-Fi and click Properties. 👇  6. Next, in Wi-Fi properties tick the Internet Protocol Version 4 (TCO/IP ) option and click the Properties button . 👇 7. Change the Obtain an IP address automatically to Use the following IP address. 👇 8. Set the IP address ...

OSI MODEL EXPLANATION

The OSI Model layers are typically described from the top layer down. The layers are described as Application, Presentation, Session, Transport, Network, Data link and Physical layer. In this section we are going to explain how the data travels from the student computer to access the OnlineLearning system server in Cobham College IT Center.   Student’s/Lecturer’s computer > Ø   7 - Application layer The application layer interacts directly with the user's data and recognize it, such as the student. The data of the student will travel from their computer to the server of the OnlineLearning system. Software applications like the internet browser are used to initiate communication with the user in order to access the system. The software used clearly does not fall into this layer. Application layer only responsible for protocols and data handling for the software being used. Ø   6 - Presentation Layer Presentation layer mainly responsible for preparing the da...
