TCP/IP Setting Manual

Step 1:

Click Settings in the search engine. After that, go to Control Panel. After the Control Panel appears, you must select "Network and Internet".

Step 2:

After that, click the "Change adapter settings" button on the left side of the window. Then it will shows two networks.

Step 3:

To complete the settings, select the "Ethernet" network.

Step 4: 

Right-click on the Ethernet and select the "Properties" option.

Step 5:

Then double-click on "(Internet Protocol Version 4) TCP/IPv4".

Step 6:

After the General interface appears, you must click on "Use the following IP address" to be able to edit the IP address.

Step 7:

Use the following IP address that we have calculated: 210.22.15.0

and for the subnet mask, use the default for class C: 255.255.255.0 

After that, click OK. 

Finish. It's not essential to restart your computer.

Goodluck!

Subnetting Calculation

Using Fixed Length Subnet Mask (FLSM)

Assume the IP Address of Online Learning System Server is  210.22.15.0.

The IP Table:

Subnet Number	IP Number
0	Network Address: 210.22.15.0 IP-Address: 210.22.15.1 to 210.22.15.62 Broadcast Address: 210.22.15.63
1	Network Address: 210.22.15.64 IP-Address: 210.22.15.65 to 210.22.15.126 Broadcast Address: 210.22.15.127
2	Network Address: 210.22.15.128 IP-Address: 210.22.15.129 to 210.22.15.190 Broadcast Address: 210.22.15.191
3	Network Address: 210.22.15.192 IP-Address: 210.22.15.193 to 210.22.15.254 Broadcast Address: 210.22.15.255

1.The class of IP Address: Class C

2. Default Subnetting Mask for IP address: 255.255.255.0

3. Quantity of subnet: Assume 4 subnet

4. Quantity of bit borrowed: 2

Formula to calculate 

2^bb = Number of subnet

2^2 = 4

5. Quantity of host for each subnet: 62

By using formula 

2^bit left - 2

2^6 - 2 = 62

OSI Layer Model

What is OSI Layer Model?

The Open Systems Interconnection (OSI) model is one of the computer network models that is responsible for establishing a connection between the sender and the receiver and sending data in a seamless way. OSI model has seven layers and each layers defines a set of typical networking functions. OSI was introduced in 1983 by representatives of the major computer and telecom companies and was adopted by ISO as an international standard in 1984. Even though the modern Internet is not based on the OSI model, but it is still widely used since it impossible to understand the modern networking terminology without knowing the concept of OSI model. This is because OSI model helps to visualize how networks work and helps isolate and at the same time troubleshoot networking problems.
