Since the opening for connection to the Internet has a lot of contribution to global development in many directions. It also helps to reduce the travel time of information and communication technologies, people are more productive and informed.
Today, as we continue to use the Internet top-level Internet connectivity has also been developed for the use of its advantages.
Different Types of Internet Connections
Analog
Connecting to the Internet is generally viewed as an analogue Dial-Up Internet access. This type of connection to the Internet is very accessible, but it is also equipped with a low temperature of at least 2400 bps to 56 kbps with this type of connection to the modem in your computer that dials the number that you received from your Internet Service (ISP) for connect to the Internet. These data are transmitted via analog telephone service.
ISDN
ISDN (Integrated Services Digital Network) is the global standard for data, voice and video via a regular digital phone lines. This type of Internet connection you can as fast as 128 kbit / s and is typically at least the speed of 64 Kbps.
B-ISDN
B-ISDN (broadband ISDN), this type of connection to the Internet is almost identical to the ISDN connection, with the exception of B-ISDN telephone lines, optical fiber, rather than the phone cable to connect the data processing.
SONET (Synchronous Optical Network), and is a widely accepted format for the activation of optical fiber transmission system operator. This system is the fundamental basis of B-ISDN physical connection to the Internet.
DSL
DSL (digital subscriber line), this type of Internet connection with 2-wire copper telephone line, which is in the room. This type of connection allows you to always be connected to the Internet, and you still have a telephone line for calls.
ADSL and SDSL are the two main classification of DSL home.
ADSL
ADSL (Asymmetric Digital Subscriber Line) is an Internet connection ADSL modem to connect to the Internet. This kind of attitude from 1.5 to 9 Mbps and below, at a rate of 16 to 640 kbit / s higher data rates.
SDSL
SDSL (symmetric digital subscriber line), this type of Internet connection you can increase the number of available data, the transfer of copper telephone lines (POTS). Digital transmission of data are processed on a platform of high frequency lines, which are as fast as 3 Mbps ADSL In contrast to this type of connection to the Internet can not coexist with its phoneâ € ™ with the function of regular calls, if both of access, such as cable and telephone.
Cables
Cable internet connection type of broadband Internet access via cable modem, cable-TV lines. Special TV channels for the transmission and processing of data between the computer and Internet connection.
Coaxial cable for cable television offers a variety of tools for its high capacity and, hence, a faster connection to the Internet for its users.
Cable connection to the Internet can be carried out at a speed of 512 kbit / s up to 20Mbps at maximum.
Wireless Internet
Connecting to wireless broadband Internet access makes the use of telephone wires or cable. It allows the device to connect to the Internet using radio spectrum bands.
The device does not need to enter to access the Internet, you can navigate and access to communications.
This type of connection, mainly in urban areas, as well as an expensive type of Internet connection.
T-1 lines
T-1 employed by companies and small businesses. This connection to the Internet, specifically focusing on data at a speed of 1,544 Mbit / s
T-1 connection is made up of 24 different channels, each channel is capable of sustained speeds of 64 kbit / s transfer.
T-1 bonded labor
A bonded T-1 consists of two or more T-1-grouped lines. This is a kind of Internet connection, which is two times higher than the speed and twice the number of channels, as compared with standard T-1 port.
T-3 lines
T-3 telephone lines connected to a specific internet connection, in which 43 rates of 45 Mbit / s transfer. Since T-1 T-3 Internet connection is also available to individual channels.
T-3 in the language of the majority of providers (ISPs) is the ISPA € ™ S the spine connect to the Internet, is also connected to the upper structure of the Internet.
Satellite
IOS (Internet via satellite) provides Internet connectivity via satellite to orbit the Earth. It offers data transfer slower because of the distance of travel information from the Earth to the satellite and back.
This connection to the Internet can be a minimum speed of 492 Kbps, 512 Kbps and the maximum
Most types of Internet connection are available for users in general. Some of these compounds, such as T-1 and T-3-link for companies and businesses because of high costs.

Connection to Internet
Ethernet
Ethernet is the accepted standard for communications protocol, which has its roots in software and hardware devices to the LAN (local area network)-structure. He was first introduced in 1973 by Bob Metcalfe at Dix (Digital, Intel and Xerox-) society. Ethernet was subsequently as a standard model for local area networks in the world.
The term Ethernet, as a rule, based on computer communication on the overall structure of the coaxial cable. Coaxial cable as a medium for broadcasting. The connecting cables, all the devices that form a communication channel that is connected to the airwaves. Ethernet is the basis for the title on the Ethernet.
This general concept of Ethernet on the original structure later for more efficient use and reliable system. It was not long before Ethernet-based standard based on a LAN (local area network) structures. A € "has been used to link Ethernet switches and hubs, more profitable and efficient.
Starla marked the first stage of technological development of coaxial cable to the Ethernet twisted pair buses for the network. This made the system more competitive on the structure of Ethernet technology significantly reduces installation costs.
Ethernet can be at different speeds with the appropriate fee category of the cable at any speed.
Categories Ethernet cable
Cat-1
Cat-1 wiring in the local regular Plain Old Telephone Service (POTS) and Integrated Services Digital Network (ISDN). ISDN is a digital standard for the transmission of POTS. This class is not approved by the TIA (Telecommunications Industry Association).
Cat-2
Cat-2 is a widely used type of wiring 4MBit / to Token Ring networks. As the cat-1 cat-2 cable is not a (TIA).
Cat-3
Cat-3 cable, commonly used in Ethernet networks, 10 Mbps Ethernet CAT-5 cable. This cable is capable of up to 16 MHz, the frequency data. Ethernet Cat-3 cable TIA/EIA-568-B.
Cat-4
Cat-4-cable in local networks in Ethernet, so that it works at 16 Mbit / s and can take up to 20 MHz. This type of Ethernet cable is not properly TIA / EIA.
CAT-5
Cat-5 Ethernet cable, category, usually in the 100Base-T and 1000Base-T. This is due to their ability to transfer data at a minimum rate of 100 Mbit / s at a temperature slightly higher proportion of Ethernet.
Cat-5E
Cat 5e Ethernet-cable category that properly TIA/EIA-568-B. This cable is virtually compatible with CAT-5, the only difference is the Cat 5e-twice as efficient and functional for a CAT-5 cable. Cat 5e-up to 125 Mbps and is ideal for the category of Ethernet 100Base-T and 1000Base-T (Gigabit Ethernet)
Cat-6
Cat-6 Ethernet cable has been designed with the fastest and most efficient technology compared to CAT-5-and-Cat 5e. This category of Ethernet cable can be up to 250 Mbit / s frequencies.

Past Official: Google Now Supporting IPv6
Two months after launching the main search site in the IPv6 version, Google is now officially announced that they have support IPv6. Article below is a direct translation of the announcement in the official Google blog.
We are very health internet. Recently, we are concerned that the IPv4, the address - the address used to connect computers to the Internet will run out. Predicted at this time showed that IPv4 addresses will run out of time at the end of 2011, and although some technologies such as Network Address Translation (NAT) may provide temporary solutions, they make the Internet a complex architecture and make a new application development.
Therefore we are very pleased to announce that the Google search is now available through IPv6 in ipv6.google.com (you will need IPv6 connection to access the site).
Where IPv4 provides about 4 billion IP addresses - not enough to provide a single IP address for each - the earth's population, amounting to 6 billion, IPv6 provides enough addresses to provide three billion networks to every human being on earth.
We hope to enable each computer and portable equipment in the network to be able to communicate directly - an idea called the "end to end principle" a very important design internet - IPv6 will enable the growth of the Internet continuously and allows the discovery of new applications.
With operating systems such as Windows Vista, Mac OS X and Linux providing high-quality support for IPv6, we hope that the implementation of mass IPv6 only time only. For that, we will complete our work quota.

Australian scientists Create Internet 100 times faster
Computer users are frustrated with the slow Internet connection momentarily can browse the web 100 times faster owing to new technology from Australia. Scientists from the University of Sydney said that they have developed a new technology that can accelerate the Internet without additional charge to users.
Described as a "small crack in a glass," photonic integrated circuits to improve the performance of traditional fiber optics, said Professor Ben Eggleton.
"This circuit crack use as a guide or point of information, like the car that can move from one rail to the other metals, but the movement only takes one picosecond. This means that in a second button is active and non-active about a million times. "
Prof. Eggleton said that this technology has been developed over the last four years. Currently we are still using electronic switching to a working quite well, but with the advancement towards our future high, consumers want the Internet satisfactory.
Prof. Eggleton said the initial testing of this technology indicates the possibility of obtaining speed Internet up to 60 times from the network Telstra is now.
If developed further, the circuit can generate speeds of up to 100 times, he said. "We are talking about a network that has the potential to increase speed up to 100 times without charge customers with cost more."
