BROADBAND

BY

REBECCA COX

Broadband

Broadband refers to telecommunication in which a wide of frequencies(wide band) is available to transmit information. Because a wide band of frequencies is available.

With there different frequency's they can travel down lots of different channels allowing more information to be able to be transmitted at any time.

Baseband

Baseband is another type of system in which information is carried in digital form on a single unmultiplexed signal channel.

“This usage pertains to a baseband network such as Ethernet and token ring local area networks.”

Differences

DSL CABLE

DSL is more reliant but slower than cable.

DSL is phone-line broadband.

Cable is faster than DSL however it may not be as reliant.

Cable is tv cable broadband (traditionally faster)

WPA Vs WEP

WPA WEP Wi-Fi Protected Access

“A security protocol for wireless 802.11 networks from the Wi-Fi Alliance that was developed to provide a migration from WEP.”

Wired Equivalent Privacy.

“This is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN”

Fixed IP Vs Dynamic IP“In a traditional TCP/IP network architecture each computer is

assigned a permanent IP address”

Fixed“Once the address is assigned it will not change, unless someone does it manually. It is called a fixed IP address”

Each computer is assigned with an IP but when lots of computer are doing this this can be difficult. IP is to do with web addresses too.

Usually it would be businesses with fixed ip addresses.

Dynamic“This server is a software program that assigns IP addresses to computers with no manual intervention.”

Therefor this makes it a lot easier for network configuration.

For example if I went onto a website my ip address would automatically to my network and they would switch on my internet.

Different broadband Mediums

Mobile Phone

Computer

Laptop

Ipad

TV

Interesting statistics on internet video through both tv and their pcs.

Modem

A modem is a box where is can convert the computers digital signal to frequency's to a telephone line or a cable television line. It makes the frequency's into digital data.

A wireless router

Wireless router looks like a modem but the differences is that a modem is what you use to actually receive your internet connection through phone line or cable. A router splits that connection up so you can use it on multiple computers.

Other types of broadband.

Much like cable and DSL there are other types of internet such as :

. Leased Lines

Local Area Network

Satellite broadband

Cellular broadband

Power-line Internet

Wireless ISP

Different deals

Each company or individual can get different broad packages to suite the individual.

.For example someone might get a combined phone line and internet at a deal price.

.There may be a deal on using broad band on your mobile.

.A business may use a bundle, e.g. different network speeds and cheaper price.

Interview

I interviewed Colin Baker a Technologistfrom TV3/ owner of the store Back from the Future which is a technology shop located on Ainger street in Dublin.

Here's what he said about his business and the broadband he uses in his store………

Back from the future

Back From the future

I interviewed Colin Baker the owner of bftf and asked him some questions and this is what he said….- What broadband do you use in your business?- Why?- How much do you pay for it?- Are you happy with it?

“We use UPC because it has the fastest internet speed in Ireland. For example in comparison to eircom, eircomsfastest speed is UPCs slowest speed. UPCs fastest speed is 100Mb. We need this type of speed for the work we do. Most businesses would use UPC for the reasons that eircom and emoblie networks like wimax and emoblie are fine for personal use and everyday downloading etc but with UCPs fibre power broadband and their speed most businessees would seek their broad band speed.

We also use UPC because the technology behind it is thick copper wire and optic fibre network that offer a lot more. However we do have a back up internet in case anything goes wrong! We need to in our line of business. Theback up we use is eircom. We pay 99e per month with UPC and we get unlimited download and upload usage. With UPC they cater for most areas throughout Ireland but not all. Being a technology store we are extremely happy what UCP has to offer and the are constantly upgrading and invention new and faster broadband.”
