HI everyone.
Here we meet again. Everyone is talking and using internet nowadays. It feel like life is incomplete without internet. Do you agree? Hahaha.. It seems like it was too much to say that but that is the reality thought. However,have you ever wonder since when the internet is created and developed?
Well,now i will share with you this knowledge that i got during my lecture today.
To begin with,let us learn and know the basic term about internet. Internet is a global system of interconnected computer network that use the standard internet internet protocol suite(TCP/IP) to link several billion devices worldview. We usually uses internet to communicate with people all around the world.
In the past,people used Morse Code that is dots and dasheh, or short signals and long signals. however,today we use a binary code to send a signal to communicate, but still the Morse Code is being used up until today.
Alright, now that is for the basic. Before we move on to the next exciting parts,let me show you the summary of the evolution of the internet.
YEAR | DEVELOPMENT OF INTERNET |
1945 | Memex conceived |
1948 | A Mathematical Theory of Communication |
1958 | Silicon Chip |
1962 | First Year Computer Network Envisioned |
1964 | Packet Switching Invented |
1965 | Hypertext Invented |
1969 | ARPANET |
1972 | TCP/IP Created |
1984 | Internet Named and Goes TCP/IP |
1989 | WWW Created |
1993 | Mossaic Created |
1995 | Age of eCommerce Begins |
A very big applause to the scientist who tried their best to improve the communication of internet. For more info on this,you can move your mouse to this link
Now,do you know that the link above s called as URL?URL is a Universal Resources Locator that directed you to the specific site. Let me add up your knowledge about the URL. The http:// is called a Protocol. The internetsociety.org is called as a Host Name while the rest is a File Name. Have a look at an image below for more understanding.
The next important part of internet is IP Address. We know that computer used a binary code as their languages. However,this code cannot be understand by human, So,we convert the 32-bit internet address to IP address to dotted decimal format. How to convert it?
Firstly, we divide the address into 8-bit octet like in the image below.
Then we convert each binary octet into a decimal number.
Let say that we have 01100011 as a parts of the 32 bit number. Then we put the number in the octet position and convert each binary into decimal number. After that, we add up all the decimal number. The result of the binary number is 64 + 32 + 2 = 98. Got it? It is easy right?
I will leave you with the picture of IP address so that you can understand more about it. For now,let us just end it here. Time is running out quickly. See you next time. Stay healthy and use remember to use the internet wisely.
