Types Of Internet Connection
Internet is a system of interlinked computer networks that connects devices on a global scale, with the aid of internet protocol suites (TCP/IP). It is a network of private, public, government, academic, business from a local network to the broadest level, linked by a wide array of electronic, wireless and optical network technologies.
Internet research is the process by which we use internet information services, especially free services, from the web or other internet-based services, (like online discussion forums). The internet holds a wide range of information resources and services that can be useful for our day to day activities. This information can be accessed only when there is internet connection.
This is when individuals and organizations gain access to use the internet on computer and mobile devices, making them connect to internet services, such as email and web services, world wide web (www). Various types of technology are being utilized by internet service providers (ISPs) to render internet services at varying speeds. Internet access is required for conducting internet researches. This is one of the major reason we use the internet.
The growth in internet acceptance, and in its importance as an information provider is directly linked to how much information is carried on the internet, as well as availability of relevant information, and how fast the information available is reached.
Internet has grown from just as much importance as television as it was in 2012 to be the most important source of information with a 3.9 out of a 5.0 scale, next to personal contacts, which has a 4.2 points.
Types Of Internet Connections
Internet access at the initial stage was not generally available to the public. In 1995, only 0.04% of the world’s population had access to the internet, with the United States of America, making over half of the entire population with internet access.
Our need for better and faster internet connection increases as technology grows. The connection speeds listed below represents general mean speed to maximum speed as at the time of publication. This is because internet speed changes and it also varies with internet service providers (ISP).
- ISDN – Integrated Services Digital Network: it is the standard international communication network which is used to send data, video, text, and voice messages via digital phone lines. ISDN has a speed range of 64kbps to 128kbps.
- DSL–Digital Subscriber Line: DSL lines are often referred to as an “Always on” connection. It uses 2-wire copper telephone lines to the premises, so internet service is delivered simultaneously with wired telephone lines. ASDL and SDSL, are the two most commonly used DSL, for home subscribers. All types of DSL internet are referred to as xDSL, with a speed range of 128kbps to 9mbps.
- ADSL–Asymmetric Digital Subscriber Line: This is the most commonly used type of DSL in North America. ADSL supports a downstream speed of 1.5mbps to 9mbps i.e when receiving data, while it’s upstream rate (the speed when sending data) is from 16 kbps-640kbps. ADSL needs a special modem to work.
- ADSL+2–ADSL Extension: This provides a faster internet when compared to ADSL, it is an extension to the traditional ADSL. Subscribers must be in close range with the internet provider to receive the ADSL+2 service.
- SDSL–Symmetric Digital Subscriber Line: SDSL works by sending digital signals through an area of high frequency telephone lines. SDSL has an internet speed of 3mbps. SDSL is known as symmetric due to the data rate, it uses same rate when sending downstream traffic and upstream traffic.
- VDSL-Very High DSL: is just like a DSL, but it offers fast internet connection over a short distance – the shorter the distance, the faster the connection.
- Cable-Broadband internet connection: it provides broadband internet connection through the use of a cable modem. It uses TV channel space to transmit. Cable TV uses coaxial cable that provides a broader bandwidth than telephone lines, and accommodate more customers. Cable internet has a speed range of 512kbps to 20mbps.
- T1-Lines Leased network: They are a popular leased lines option for internet connection among businesses and among internet service providers (ISPs). A T1 line consists of 24 individual channels, each with a speed of 64k bits per second.
- Bonded T1-Lines: Two or more T1s are bonded to increase bandwidth. When a single T1 leased line provides 1.5mbps, two bonded T1s provides 3mbps. A typical bonded T1 is two T1s, and runs at 3mbps.
- Optical Carrier 3 (OC-3): Optical carrier level 3 (OC3) specifies the speed of fiber optic networks, and are used to satisfy large networks with large voice, data, video and traffic needs. OC3 has a speed of 155.52 mpbs, an estimated speed of 100 T1 lines
Facts About The Internet
- According to Google, the internet consisted of five million terabytes of data as at 2010. The number of pages on the internet as of September 4, 2015 was over 45 billion.
- Out of the seven billion people on earth, more than three billion people are online, as reported by the InternetLiveStats on September 5, 2015. This statistic is expected to grow by 2020.
- 250 billion emails are sent on a daily basis, with spams making 81%, that means 50 billion emails are being sent by humans daily. The first spam mail was sent in 1978.
- It took only four years for the internet to reach its first 50 million users, while it took 13 years for television and 38 years for radio to reach the same number of users.
- 72 hours of video contents are being uploaded on YouTube every two minutes. By the time you finished reading this article, more than 150 million hours of videos would have been uploaded on YouTube. YouTube boasts of one billion users every month, and an average internet user spends four hours on YouTube every month.
There is always an internet connection rate that can meet your internet needs, in terms of bandwidth, cost, reliability and availability and so on and so forth. For instance, fiber optic networks have the properties to provide data for large business organizations, while DSL lines can meet data needs of home subscribers. Internet has grown from just 2400bps to 56kbps rates, as it is for Analog: Dial-Up Internet Access. Today analog lines are being replaced by broadband services (cable and DSL), however, fiber optic is the most suitable for business use.
