Week 8 -The last lecturer- internet ^^

Well, its a roller coaster ride for this semester and without i even noticing it, it's already the last lecturer for the telecommunication course. Mixed emotion arise in my mind when I enter the class; happy as we finally complete this course but feel pressurize as the final exam is just around the corner. Back to the main point though, today we learn about internet . For me, internet is a essential part of my life especially after i enter UTM   as it is my main medium of entertainment and relaxation. I always though internet as a mean of getting information and data globally. 

Internet is actually defined as  The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide.

The Internet protocol suite is the set of communications protocols used for the Internet and similar networks, and generally the most popularprotocol stack for wide area networks. It is commonly known as TCP/IP, because of its most important protocols: Transmission Control Protocol(TCP) and Internet Protocol (IP), which were the first networking protocols defined in this standard. It 
TCP/IP provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. It has four abstraction layers, each with its own protocols. There is a arrangement/ hierarchy for the connection to internet; from single computer to LAN ( local area network) to ISP  to WWW ( world wide web )  We just need computerweb browser and internet access to connect ourselves to the internet.web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web.

An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. The designers of the Internet Protocol defined an IP address as a 32-bit number. An IP address consists of two parts, one identifying the network and one identifying the node or host. The Class of the address determines which part belongs to the network address and which part belongs to the node address. All nodes on a given network share the same network prefix but must have a unique host number.

An Internet service provider (ISP) is an organization that provides access to the Internet.
Internet service providers can be either community-owned and non-profit, or privately owned and for-profit.
Access ISPs directly connect clients to the Internet using copper wires, wireless or fiber-optic connections. Hosting ISPs lease server space for smaller businesses and other people (colocation). Transit ISPs provide large amounts of bandwidth for connecting hosting ISPs to access ISPs.

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web.
Hypertext is a multi-linear set of objects, building a network by using logical links (the so called hyperlinks) between the nodes (e.g. text or words). HTTP is the protocol to exchange or transfer hypertext.

Ok, i thinks that's all from me. Hopefully you all enjoy reading my blog. Thanks for the support ya ^^.
