Some DSL Broadband definitionsWritten by Steve
Some DSL Broadband definitions, Often too many people get confused with all definitions, here we have explained in easy to understand terms. ADSL: Asymmetric Digital Subscriber Line - asymmetric meaning it's faster downstream than upstream. ASAM: Advanced Services Access Manager -Whether you have a DSLAM or ASAM in your exchange doesn't really matter. They do same thing. See DSLAM's as well. ATM: Asynchronous Transfer Mode - a method of encapsulation which is capable of many virtual circuits. With these, providers (ISP's) can split an ATM connection (155Mbit or 622Mbit) up into many connections. ATM isn't just used for DSL but in case of DSL it's used to provision each customer. Contention Ratios A contention ratio is number of users to xMbit of bandwidth. For example some providers offer 2Mbit DSL, with a ratio of 50:1, meaning 50 users to 1Mbit of bandwidth. CPE Customer Premises Equipment, term that describes equipment used on customer end of a connection, for example your DSL modem/router, cable modem, black box on Wired Country etc. DSL Digital Subscriber Line. DSLAM Digital Subscriber Line Access Multiplexer - They are placed in DSL enabled Telecomm exchanges, when your modem syncs up and DSL light comes on, it means you are connected. When data travels down your connection, it goes from CPE -> DSLAM -> RAN -> ISP ERX Edge Routing Exchange. See RAN.
| | Finding the best search engineWritten by Ryan Fyfe
With Billions of pages on internet how do you find exactly what is that you are looking for? Chances are you have stumbled across different search engines, and maybe even used and tried out a few of them. Aside from look and feel which search engine really is best? It used to be that Google’s search results were far superior to any other search engine on internet. With an increase in technology by Google’s closest competitor’s Yahoo and Msn, it’s getting harder and harder to really sort through and say which one is really better. With that in mind I would recommend using all of major search engines to see which one returns what you personally are looking for. I’ve found that a search engine that I use all of time, and returns what I am looking for will be completely different for someone else searching for exact same thing. Everyone has expectations for what they are looking for when they perform a web search. These expectations are different for everyone, and I believe that with a slight difference in Algorithms of major search engines, one of them will match what it is that you are looking for. Features: Due to fact that there isn’t much that hasn’t already been exploited with search engine technology, all of major sites have been pushing new features, to attract users. Gmail, Google’s free web mail is an example of this. Gmail provides over 2gb’s of free storage, and is growing everyday. With ability to pop email stored on Gmail server it’s hard to beat. Yahoo and Msn have offered web based email for a long time, and it’s exciting to see Google jump in Game. Gmail is still in a Beta stage, but already it’s made a huge push in market; Even convinced Hotmail to raise their storage limit by more than a factor of 10! This is only a small preview I think we will see in next while, as different providers fight for our patronage.
