During
the ninth week, our lecturer MR. Azamuddin showed to us some videos about the
‘’Internet’’. Therefore, I learnt the history of the internet from 1957 when
the first message was sent between two
computers until now. Internet is a
connection between one network to another network. I also learnt how packets (data) reach their
destination trough Transmission Control Protocol (TCP) or Internet Protocol
(IP). However, the most important is
that internet has no center and it use to send email messages, upload and
download files, communication, and surfing the web. Moreover, the internet has
several applications which are Traditional core application such as Email, The
killer application such as world-wide web (WWW), and new applications such as
telephony. Then, I learnt about Open
System Interconnecting (OSI) and its layers. After that, I learnt about Hypertext
and the early HTML only text, links, and images. Then, I learnt about the
internet transmits data (called host or router) to another. After that, I
learnt how the internet works by Transport Control Protocol (TCP), Backbone,
and Uniform resource locator (URL). I
also learnt that a company that provide the internet to the users is called
Internet Service Provider (ISP) such as Celcom company. Then, I learnt about
the address of the (web page). I also learnt about the domain name or URL which
means a unique name associated with a specific IP address by a program that
runs on an Internet host computer. In conclusion, I learnt how to save the
personal information in the internet by use virus protection software and
Firewalls
