Motivation Activity
The Teacher will show a pictures and ask the students the following Questions.
Activity
What do you see?
What do you think why we’re able to reach people through emails or letters?
Aside from the parts of the letter. What do you think is the one of the important
element to make sure that it will be sent to the correct person?
How does this exchanging of message work?
The teacher will discuss the I.P address and the importance of I.P Address in computer.
IP address – “Internet Protocol” is a strong unique characters that identifies each computer to
communicate over a network. Each computer has each own unique IP address.
An IP address is written in 32 bits but, it is hard for humans to read the bits which is basically 1
& 0. So, IP address are then divided into parts which we call octets.
Analysis
Each octet is separated by decimal point or period. This format is called a “dotted-decimal
notation”.
Example of 32 bit IP address:
In the above illustration is the example of 32 bit IP address. If you mistyped even a single
character or number, the whole address would be changed and you may not be able to
communicate between computers.
Example of dotted-decimal notation:
In this example, we can see numbers that are separated by a point. In this case it is easy for us
humans to identify the IP address. A dotted-decimal notation are divided into four parts or we
can call it 4 octets.
Octets have its role. The first three octets are the network and the fourth is the host
Network – a server or a medium used to access remote services such as internet services.
Host – is any computer device that is connected to any computer network.
IP address may also vary in its Subnet Mask.
Subnet Mask is the network portion of an IP Address. Basically it is structured like an IP address
but it is more specific on routing the information in details. For Example, You made a purchase
online and a Delivery address is required but you only indicated your City where you live, by
the time it will be delivered, a mail man or courier services maybe confused because you are
not specific to your delivery address. The job of Subnet Mask is to make sure that every small
details are accurate.
Now, let us moved to Binary Math. In this part, we get to know the difference between bit and
byte, conversions of decimal to binary and vice versa.
Bit – 0 or 1
Byte – Eight bits or octet
Each Byte is from 0 – 255 octet
Below is the Example of a Byte
10100000 – it is composed of 8 bits.
Now we are going to convert it to octet.
In converting octet, we used this conversion table.
128
64
32
16
8
4
2
1
2
0

0
Then we can distribute each bit to the table thus making it
128
1
64
0
32
1
16
0
8
0
4
0
Our next step is to add all the numbers that has a bit (1) and leave no value for a bit (0)
128
1
64
0
128 + 0 +
32
1
16
0
32 + 0
8
0
4
0
2
0
+ 0 + 0 + 0
1
0
+
0
= 160 octet
Now, what if the octet is given and not bits?
Example : 143.24.136.12
Let us try to convert 143 into decimal. We will use the same table.
128
64
32
16
8
4
2
1
It is simple, just start from the number on left which is 128 and assigned a bit (1) if the value of
the given octet is higher than of the table and add each individual value of conversion table
until you reach the correct number. Write down zero(0) if the value is lesser than the numbers
in conversion table. A conversion number that has a 0 need not to be included in counting.
128

Therefore: the conversion of 143 to decimal is 10001111

Our lives have been impacted by technology in many different ways. It connects people and
brings them together. One of the important instances of technology is the Internet. By staying in
touch with those around us, technology has helped us build and even improve relationships. One
of the important metrics in contemporary society is convenience, which technology contributes
to. This crucial lesson needs to be imparted to students in order to foster the abilities that will
enable them to keep up with real-world situations.
