Resignation of Pope Benedict XVI (reaction)

For me in my opinion its just okay because its his own decision we don't have the rights to judge him to his decision, but i know some people can't believe about to the decision of the pope . But we will accept the fact that the pope will resign for being a pope. We all know that it was so shocking but we should understand the health of the pope because its for the own good of the pope. Even me i was also shock about it.But we don't need to be sad for that because soon  their will be another pope to be elected to handle to the church. And that's all can i say about the topic.

Types of Network connection



In choosing an internet connection, it is very important to consider your location and specially your budget. There are a lot of choices that can be considered. However, it is a common denominator among people, whether they utilize the internet for work or play, to opt for with a fast web connection.

Dial-up

The dial-up or the Analogue can be considered as the poor man’s connection because it is believed to the cheapest and slowest internet connection. It has the speed of up to 56kbs and uses an Internet Service Provider (ISP), cable and a modem to translate the analogue data. With this, the user needs to dial a phone number to the ISP in order to be connected. Moreover, the modem translates the said analogue data into digital which can be understood by the user.

DSL

On the other hand, a DSL connection, unlike the analogue, does not need dialling up to an ISP. It is an internet access that is on all the time. All you need to do is plug the two-wire telephone cable and you are already connected. With this type of connection, there are also various subtypes like SDSL, ADSL and VDSL. All these subtypes however work the same.

TV Cable modem

Another form of internet connection is the Cable modem which is relatively faster than the previous types. It has a speed of 512kbs to 20Mbps and uses television lines to be able to connect into the internet. Compared to telephone lines, cable TV uses coaxial cables which provide higher bandwidth.

Broadband and Optical

Broadband is a connection that does not need a modem in order to be able to connect unlike other types of connections and is believed to be the most reliable. Talking about cable connection, there is another type called Optical Cable that can reach a speed of 16Gbps+. It is fiber-optic and has the highest data rates compared to the other common internet connection and is fairly easy to maintain.

Satellite

Meanwhile, a connection over Satellite is stable however; it has a slower speed than that of broadband because of its distance. This type of connection uses a communication satellite that is positioned in the orbit that provides an uninterrupted connection but due to its very far distance from the users, it transmits data slower than normal.

Tier Carrier

Further, there is a type of internet connection that can be connected to the backbone of the internet itself. You can research t1 service providers online. This is the kind of connection that is used by ISP. Tier Carrier has subtypes that vary in speed and number of individual channels that they carry. With the T-1 line, it can carry up to 26 individual channels while T-3 can carry up to 672 and with a speed not slower but can be higher than 43Mbps. A T-5 however has the speed of up to 400Mbps. This kind of connection is impractical to be used by home-based computer sets.

Internet2

Moreover, if you think you have the fastest connection, think again. Today, there is this type of connection that can reach a speed of up to 100Gbps. Internet2 is believed to be the world’s fastest internet connection and it really feels different to have this kind of connection. This was developed through the effort of a networking consortium to provide a high internet speed for education and research purposes. Still, it remains an alien thing to have such a connection.

How is Internet used ?

As the internet has grown, it has developed into a multifaceted tool with a vast range of uses. It's now easy to keep in touch with friends, publish your own articles, or even watch your favorite TV shows using the internet.
In this lesson, we'll talk about some of the ways the Internet is used today, including blogs, social networking, instant messaging, VoIP, and media.

 The internet isn't just about finding information. It's also about connecting with friends, family, and people you've never met before. Today, there are many different ways to communicate online, including social networking, chat, VoIP, and blogging.

What are two types of computer networks?

LAN - Local Area Network

A LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings. In TCP/IP networking, a LAN is often but not always implemented as a single IP subnet

 In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organization. They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring.


WAN - Wide Area Network

As the term implies, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth.
A WAN is a geographically-dispersed collection of LANs. A network device called a router connects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address.
A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances.

What is the Internet ?

The Internet (or internet) is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.


Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Newspaper, book and other print publishing are adapting to Web site technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.
The origins of the Internet reach back to research of the 1960s, commissioned by the United States government to build robust, fault-tolerant, and distributed computer networks. The funding of a new U.S. backbone by the National Science Foundation in the 1980s, as well as private funding for other commercial backbones, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The commercialization of what was by the 1990s an international network resulted in its popularization and incorporation into virtually every aspect of modern human life. As of June 2012, more than 2.4 billion people—over a third of the world's human population—have used the services of the Internet.[1]

The Internet has no centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own standards. Only the overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols (IPv4 and IPv6) is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise.
