Internet Addresses

~Internet Addresses~

1. What is a URL?

URL or Uniform Resource Locator and is commonly known as the web address of a web page.

2. What is an IP address and how is it related to a URL?

Each computer that's connected to the Internet has its own IP address and when you access a web page by entering in a URL, the browser communicates with a name server to turn the name server into and IP address for the computer to connect to the server machine.

3. Given our school web site's URL is http://www.mcauley.nsw.edu.au/, what is our domain name and what protocol do you need to use to access the site?

The domain name is "mcauley" and the protocol used to access our school's site is HTTP which stands for HyperText Transfer Protocol.

4. In the context of an IP address, what is an octet?

The four numbers in an IP address are called octets, as they each have eight positions in binary form and when you add all the positions together you end up with 32. This is also why IP addresses are 32-bit numbers.

Broadband Speedtest

Using the site above I tested the upload and download speeds of the Internet using the school computer that I'm currently working from. The results are as follows;

ISP: Datafast Telecommunications

Download speed: 4.21 Mb/s

Upload speed: 0.57 Mb/s

1. What is meant by upload and download speeds?

The upload speed is the speed at which data is transferred from the user's computer onto the Internet and the download speed is the speed at which data is transferred from the Internet onto the user's computer.

2. What are the units used to measure download speeds?

The default setting that's used to measure the download speeds is megabits per second (MB/s), but under the settings option you are able to change the unit of measurement into kilobits, kilobytes and also megabytes.

3. Why do different locations offer different download speeds?

Different locations can offer different download speeds depending on the type of Internet you have, such as ADSL, ADSL2+, cable, DSL and dial-up. From this, if you have any form of ADSL, you share the line with your neighbours and at certain times the usage of the lines peak which slows your download speeds as well as theirs due to congestion on the line, but when using the Internet at off-peak times the download speeds are faster. The speeds can also depend on how far away you are located from your Internet Service Provider (ISP). Usually if you are within 2 kms of your ISP then you should be reaching the speeds that the company you are with claim to be reaching, but if you're located outside of that range the download speeds you are reaching may be lower than claimed.
