Deciphering the 'geek' ...


1. So whats ‘broadband’ anyway?
As the name suggests, a broadband signal contains a wide range of frequencies so that the greater the bandwidth, the more information it contains. Narrow bands in radio carry Morse code while slightly wider ones hold speech. Broader ones carry music in order to ensure that the sound is reproduced as close to the original as possible.
‘Normal’ TV antennae can pick up quite a few channels – a broader band will pick up a lot more.

2. What on earth is 'routing'?

Broadband's public transport. It hops the 'bus' and travels along a route of fibre optic cables allowing for a larger amount of information to be carried than a normal telephone modem. Like multi-laned highways, alot more data can be sent all at once due to carrying capacity.

3. What's  bandwidth?
As it turns out when it comes to internet usage - size does matter. The capacity of the bandwidth affects the  ability of the communications line or pathway to transmit data. The more bandwidth, the merrier the party!

4. How do I know how much bandwidth I am using?
You can login to the site and see how much you are using at any give time – simply visit http://login.edsl.co.za

5. What does ADSL really stand for?
It actually stands for Asymmetric Digital Subscriber Line. The thing that makes it different from other DSL lines is that is Asymmetric with a data flow that’s greater in one direction than another. Think upstream (like salmon) and downstream (like normal fish). In other words it allows the ‘internet download process’ to be a lot faster than having to run servers that would need a higher speed in the opposite direction.

6. So whats 3G then?
The ‘third generation’ of standards and ‘mobile’ technology which allows you to be connected anywhere at anytime within a circumference of 1km of the tower.

7. ADSL vs. 3G?
Fixed vs. mobile. 3G picks up signals on the move while ADSL isn’t subject to much ‘roaming’ – at least with 1km restrictions of a 3G tower - you do the math.

8. How does my server serve me?
By sending your internet requests back and fourth making sure that they are fulfilled via an application designed to do just that. A proxy server does the same but just from a different server and on your behalf.

9. And Wi fi is...?
Wireless technology used for internet, gaming and in certain cases TV and DVD.

10. What’s LAN?
LAN is a connected local area computer network that exists within an office, school, set of closely located buildings or home where there is more than one computer connected to the network.

11. How is LAN connected to the Ethernet?
Derived from the word ‘ether’ ; a kind of technology devised specifically for connecting LAN’s.

12. How does web hosting work?
Web hosts offer a service that allows you to run your own webpage by providing space on their server for you.

13. What do you mean it's Capped?
A ‘download cap or bit cap’ is the amount of data allocated vs. the time period over which it is used.  For example - a 1 Gig cap allows you to download 1 Gigabyte (1 billion bytes) of traffic in a month. One gig is roughly equivalent to 12 hours of flash video. If you are capped you need another gig or two - depending on what you want to get up to.

14. What’s a Firewall?

A type of ‘gatekeeping’ software that operates from an allocated terminal specially acting as an information filter on your behalf, according to a set of rules which forbid or allow certain web data to pass through

15. How does your Fixed IP ADSL work?
We assign a host name to the IP that gets allocated to you, so you are always able to locate your IP and get into your router. Your name will always be in the format of loginname.edsl-dns.net Substitute loginname with the first part of your edsl login.
