What is INTERNET? Part2

What is ISP??

An ISP, or Internet Service Provider, is a company that provides you with a point of access to the Internet. When you connect to your ISP, your computer (or your own network) becomes an extension of the Internet itself whilst you remain connected.

How to choose ISP?

What technology is right for you?

Dial-up
If you only want to use the internet every now and then, do not mind waiting a few minutes to connect and disconnect each time you want to use the internet, and do not need wireless access, then dial-up may be right for you. Dial-up can also be a good option for those who are traveling and want to occasionally check email or browse some web pages. Keep in mind that you need access to a land-line telephone service in order to use Dial-up.
DSL or Cable
If you regularly use the internet, you will probably want a DSL or cable connection. Cable can be faster than DSL, but most people can find what they need from either one of these services. Also, for those who want a reliable wireless connection, you can connect to DSL or cable internet wirelessly with a wireless router.
Satellite
If you regularly use the internet, but live in an area where DSL or cable connections are not available, a satellite connection may be your best option. Satellite connections are wireless and much faster than dial-up, but they are limited in their ability to connect to streaming content, can be affected by the weather, and their price is comparable to DSL or cable connections.

Do you need a more portable option?

If you need portable internet access for a mobile device such as a phone, tablet or laptop, you will need an ISP that offers a service such as 3G, 4G, Wi-Fi or Wi-Max. This would not typically be your primary method of connecting to the internet; you should also have a Dial-up, DSL, cable, or satellite connection.

Performance measures

When choosing an ISP, ask for an indication of the level of performance you will receive. Finding a simple, understandable measure of performance is not an easy task. A typical consumer should know the following:

The user's experience in getting online. In other words, what is the likelihood that you will get connected the first time when you dial-up your ISP and not receive an engaged signal because their modems or access servers are full?
Once you are online, what data speed can you expect to receive? In other words, how long should it take you to download a particular file or page? and
What is the risk of your connection to your ISP being disconnected or 'dropping out' as a result of an ISP's management of customer traffic in its systems?

Sometimes the answers to the second and third questions can be hard to obtain as performance in these areas is not always within the control of your ISP.

This is due to:

factors such as the time of day and traffic on the internet causing variations in the internet's performance;
variations in the performance of the location, equipment and communications devices of different users; and
variations within the performance of the ISP's equipment.

broadband

Beginner's broadband. If you are just starting out, it's likely that you're looking for a package that's easy to set up, not too expensive and offers good customer support.
Heavy-Use broadband. You know if you are a heavy-user if you enjoy downloading oodles of songs and movies using peer-to-peer software, or you're a big fan of online gaming. Either way, our heavy-use packages are the ones to look out for.
Business broadband. These packages differ from consumer deals as they offer extras like static/fixed-IPs, webspace and email addresses as well as routers and secuity suites.
Mobile broadband. If you access the Internet primarily from your laptop, then mobile broadband is an option worth considering - whether to be used at home or on the go. Mobile broadband providers will send you a 'dongle' (modem) that you plug into the USB slot on your laptop to access the Internet, at broadband speeds, wherever there's mobile phone coverage

Measuring bandwith

While bandwidth is used to describe network speeds, it does not measure how fast bits of data move from one location to another. Since data packets travel over electronic or fiber-optic cables, the speed of each bit transferred is negligible. Instead, bandwidth measures how much data can flow through a specific connection at one time.

When visualizing bandwidth, it may help to think of a network connection as a tube and each bit of data as a grain of sand. If you pour a large amount of sand into a skinny tube, it will take a long time for the sand to flow through it. If you pour the same amount of sand through a wide tube, the sand will finish flowing through the tube much faster. Similarly, a download will finish much faster when you have a high-bandwidth connection rather than a low-bandwidth connection.

Data often flows over multiple network connections, which means the connection with the smallest bandwidth acts as a bottleneck. Generally, the Internet backbone and connections between servers have the most bandwidth, so they rarely serve as bottlenecks. Instead, the most common Internet bottleneck is your connection to your ISP.

NOTE: Bandwidth also refers to a range of frequencies used to transmit a signal. This type of bandwidth is measured in hertz and is often referenced in signal processing applications.

Who owns Internet? Who governs/regulates control the Internet?

We always think that 'WHO OWNS THE INTERNET?'

There are many organizations, corporations, governments, schools, private citizens and service providers that all own pieces of the infrastructure, but there is no one body that owns it all.

No one actually owns the Internet, and no single person or organization controls the Internet in its entirety.

The Internet is more of a concept than an actual tangible entity, and it relies on a physical infrastructure that connects networks to other networks.

There are many organizations, corporations, governments, schools, private citizens and service providers that all own pieces of the infrastructure, but there is no one body that owns it all. There are, however, organizations that oversee and standardize what happens on the Internet and assign IP addresses and domain names, such as the National Science Foundation, the Internet Engineering Task Force, ICANN, InterNIC and the Internet Architecture Board
