Computer and internet technology has advanced by leaps and bounds in the last decade. The internet has literally changed the way we communicate and access information. Having internet service gives personal access to entertainment, communications and educational opportunities. Modern internet services give businesses the capability to fax documents, email and even stream video conference calls all over the world.
There are literally thousands of companies that can provide internet services for homes and businesses. These companies are called Internet Service Providers (ISPs). They provide internet service through various plans and means of connecting you to the internet. You can sign up with the major national providers or choose to go with a local ISP which you'll find in nearly every location throughout the country and capital including Marylebone, Greenwich, Docklands, Beckenham and Teddington.
Internet connection services
The oldest type and probably the most in-expensive connection is dial-up which is still used today. Dial-up connects to the internet through the phone line. Dial up will connect you to the internet but high speed web surfing, listening to music, video streaming or downloading large files are all but impossible at dial-up speeds. Downloading a 1MB file at 56 Kbps will take 2.5 minutes. The same file being downloaded at 6 Mbps over DSL or cable would take 1.5 seconds.
Cable internet service is delivered through the cable TV connection in the home. It uses a router which is then connected to the computer through a network card. Cable internet service is offered at many speeds based on the various pricing levels. However, no matter what speed you choose connection speeds can be limited due to shared cable usage or if the computer and network card are slow and outdated.
Digital Subscriber Line (DSL) internet service uses the telephone line. DSL services and speeds usually match those of Cable services depending on the plan chosen. A DSL connection allows simultaneous internet and voice access and it can use the phone line you already have.
The closer you are to the DSL provider's network the better the connection will be. Conversely the farther away you are from the network the weaker the signal becomes, decreasing speed. There may be problems with DSL speeds if the phone lines are in poor condition or the computer is slow and outdated as with cable internet service. DSL service is not available everywhere.
T1 and T3
T1 and T3 lines are high speed internet services that also allow simultaneous use of telephone lines. T1 and T3 lines are very reliable and typically used by businesses. The pricing is a limiting factor for home use. A DSL or cable broadband connection may cost from $30 to $60 per month. A T1 1.5 Mbps may cost $250.00 per month. A T3 connection at 45Mbps may cost $2,000.00 to $10,000.00 a month.
Wi-Fi is a wireless internet service. The signal strength and speed depend largely on the equipment broadcasting the signal. You'll find that free Wi-FI is increasingly being offered at book stores, airports and coffee shops to attract consumers.
DSL, cable modem and Wi-Fi are tied to a location. Mobile broadband internet service is wireless technology that broadcasts signals everywhere. Connections are normally provided through 3G (3rd Generation) and 4G (4th Generation) cellular networks. Smart Phones and laptops are the major beneficiaries of this technology but increasingly this technology is being incorporated into automobiles and public transportation.
Some limitations include monthly service plans that can be expensive if data quotas are exceeded. The speeds are slower than traditional broadband services. There may be interruption to signals due to roaming or geographic obstacles or interference inside large buildings.
As new internet services are introduced connectivity, productivity and entertainment delivery are reaching lightning speeds. The technology is available be it in a business, in the home or a public library it's easy for virtually everyone to get connected.
