Who hasnt heard about the internet? No one! Unless, of course, you have been living in a cave for the past decade! The internet is the crowning achievement of the Information Age (which is what we call this age we live in). It has completely revolutionized how we communicate and how we live.

But what exactly is this thing we call the internet? In a nutshell, the internet is the interconnection of computers around the world. It allows users of these computers to communicate in a variety of ways: through email, streaming conferencing, website information, file sharing, and others.

For you to connect to the internet, you will need a computer and a connection to an ISP (Internet Service Provider). Your ISP will provide you with a connection and the means to connect to the internet.

The internet started out as a project of ARPANET (Advanced Research Projects Agency of the US Department of Defense), which was commissioned by the Pentagon to look into the uses of networking for military purposes in 1960. From there, the internet was steadily developed to benefit the whole populace.

In the beginning, the internet could only chug along at a low data transfer rate. Today, ISPs offer speeds from 56 kilobytes per second to 10 megabytes per second or more! This allows people to transfer more data which facilitates better communication.

The internet impacts so much of our daily lives that it has become indispensable to so many people and businesses.

Uses of the Internet

1. E-mail ?Gone are the days when people had to wait weeks or even months to receive postal mail! With the internet, an email can be sent and reach its destination instantaneously! E-mails have made the world a smaller place, allowing people separated by great distances to correspond.

2. Instant Messaging, Chat Rooms ?Services such as AIM, Yahoo Messenger, MSN Messenger, and Skype allow people to send messages instantaneously, much like a phone conversation, but using written messages. There are also virtual rooms?on the internet facilitated by services developed for this reason. These rooms?allow many users to chat using written messages.

3. Webpages ?Webpages are like virtual homes on the internet. They allow people to post documents on the internet that are easy to browse through and navigate. As time haspassed by, webpages have gained more functionality. Today you can download files, submit files and comments, and do all your shopping online.

Webpages serve many functions: some promote businesses, some are purely informational, and some become money making vehicles. The internet spawned what we now call e-commerce. This involves purchasing over the internet. You can even use online payment methods such as PayPal, Paydot and other methods.

4. Streaming Services and File Sharing ?The internet also allows file sharing. This allows you to share files with other users. These files may be large or small. Streaming services allow you to receive data such as radio feeds, or even video feeds over the internet.

A Brave New World

In the past, the internet was limited to large institutions. Now residential internet has become more affordable. Todays technology even allows mobile internet! You could surf the internet from a mobile device such as a cell phone, or you could surf from your laptop in areas that offer Wi-Fi (Wireless Fidelity). The internet makes instant communication with the rest of the world possible. In the next few years we will see much more.

When searching for just the right bandwidth solution for critical business network applications a common choice is what's termed an OC3 circuit. An OC3 circuit works as a reliable fiber optic backbone for large networks with substantial voice/data/video traffic needs. For example....corporate headquarters phone lines (PBX and/or VoIP), company Supply Chain Management (SCM) systems, facility high security networks, Hospital medical imagery and diagnostic systems, data recovery and backup networks, video conferencing facilities, multi-media or virtual design centers, and ISP backbones.

OC3 is the abbreviated term for Optical Carrier level 3, and is used to specify the speed level of fiber optic networks over SONET. The speed itself is measured through SONET (Synchronous Optical Network) standards.

Specificly, the Synchronous Optical Network (SONET) includes a set of signal rate multiples for transmitting digital signals on optical fiber. OC stands for Optical Carrier and the number following specifies the speed of the fiber optic networks conforming to the SONET standard. The base rate OC1 is 51.84 Mbps. Therefore an OC3 circuit delivers 155 Mbps.

OC3 is optical carrier (fiber) connected by equipment capable of speeds up to 155.5 Mbps......and is designed to take, synchronize, and transport data and voice at that speed of 155 Mbps reliably. Due to their potential load delivery capacity....OC3 applications are used most often by large enterprises with significant bandwidth requirements or as an ISP backbone. By definition.....an OC3 is the equivalent of 84 T1s or 3 DS3s/T3s. To put it in perspective....an OC3 circuit is capable of 2,000 simultaneous voice transmissions with each transmission carrying variable data types alongside the voice!

An important factor to consider is that OC3s can be burstable, which allows you to start small and increase your bandwidth as your needs grow. A Burstable OC3 is the ideal solution for businesses who seek ultra-fast connectivity for their Internet needs.....and don't require full OC3 load capacity just yet but may in the future. Options cover selection from 60, 70, 80, 90, 100, 120, 140, or a full 155 Mbps of service.

Fiber Optics is a technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.

Fiber optics has several advantages over traditional metal communication lines. They have a much greater bandwidth than metal cables. This means they can carry more data. They are also less susceptible than metal cables to interference, and they are much thinner and lighter than metal wires. This enables the data to be transmitted digitally over fiber optics rather than resorting to analog transmission.

Additionally, OC-3 is most often made up of what is called a "SONET ring" to maintain it's reliability (redundancy) during its high speed transmissions.

A common method of back up used with SONET ring is called a "bi-directional ring topology." This bi-directional ring is a physical topology which deploys two sets of fiber strands.

The first strand for the connection is for sending and receiving. The second strand will reroute traffic from the original transmission in another direction should the first strand break or malfunction. Therefore bi-directional ring topology helps ensure constant reliability within an OC3 SONET based network.

So just what does an OC3 circuit do for your business?

With an OC3 bandwidth solution your network will deliver optimum speed and load for any large scale voice/data application requirement you have....with reliable and secure digital technology performance.
