What exactly arerepparttar differences between Cable and DSL Internet services?

First let's define our terms.

Bandwidth vs. Latency:

Bandwidth & Throughput Digital bandwidth or throughput is a measurement ofrepparttar 118461 amount of data that can be transferred over a digital line over a specific amount of time.

Latency Latency isrepparttar 118462 time it takes to deliver a packet of data from one place to another. This includesrepparttar 118463 time it takes for an electrical or optical signal to travel a certain physical distance (propagation delay) andrepparttar 118464 time it takes to process these signals alongrepparttar 118465 way (processing delay).

So bandwidth is a measure of frequency or a rate of service delivery while latency is a measure of time or signal delay.

Technology Comparision.

Cable service uses signals transmitted throughrepparttar 118466 same coax cable that cable television uses. DSL uses normal phone lines to send digital signals to a DSL modem.

Coaxial cable has a far greater capacity than RJ-11 phone cable. But,repparttar 118467 coaxial cable coming into your home is shared with many people outside your house and provides many services. Cable modems have higher bandwidth thoughrepparttar 118468 connection is shared among cable users in your service area and even with your digital cable box. As a resultrepparttar 118469 performance is quite similar to DSL. Generally, cable modems can achieve better peak throughput, but this high bandwidth is not consistant and depends, again, on load, affected by time of day and other factors. DSL service usually provides a more constant, consistant feed, with lower latency. The distance to your exchange or "switch" isrepparttar 118470 main factor that determines DSL quality of service. Look forrepparttar 118471 green (in Toronto) phone exchange box in your neighbourhood and note how far your home is from that box.

Service Comparison. One ofrepparttar 118472 advantages of DSL over cable modems is thatrepparttar 118473 line torepparttar 118474 exchange or "switch" is not shared. Though ISPs trying to sell DSL services will tout this as a major advantage, slow cable modem speeds have very little to do with this and have much more to do withrepparttar 118475 fact that cable service is shared among many users and services.

RSS PIONEERS SET OFF GOLD RUSH

Written by Tony Dean


The nature of cyberspace is changing fast withrepparttar rush now on to set up rss news feeds. Every gram of news and current affairs is gleaned fromrepparttar 118460 four corners ofrepparttar 118461 globe so that we may be informed as to what is happening in hundreds of different commercial fields of endeavour.

Everything from what new item is selling well on eBay, to what "Wired Magazine" is saying aboutrepparttar 118462 latest technology. More and more magazine and newspaper publishers are gaining a foothold on this new juggernaut which is going to changerepparttar 118463 way we gather news.

Advertisers too are not left out. Already some ofrepparttar 118464 largest media companies inrepparttar 118465 world are now poised to find advertising space for their clients 'branding' campaigns, on any available web page that regularly features in rss feeds.

The media companies with billions of ad dollars to spend, will they say, be spending less on newspaper and t.v. advertising inrepparttar 118466 coming years, and will concentrate instead on 'blogs' and rss feeds.

Competition will be fierce for every available space onrepparttar 118467 most popular feeds, some run by newspapers!

Many freelance journalists will be running rss feeds in direct competition withrepparttar 118468 newspaper employers who now pay them to gather news for their publication. There will be no editor to censor their news items, they will be free to write whatever they want.

This new found freedom for anyone inrepparttar 118469 world to be able to express their opinions without it costing anything, will make for a new 'House Of Babel', with maybe up to several millions of rss feeds withinrepparttar 118470 next five years run by private individuals all overrepparttar 118471 world. The only needed resource to set up a rss feed is free hosting on a server anywhere inrepparttar 118472 world, and these web hosts are plentiful.
