Advantages and Disadvantages

Advantages of Wireless: 
- Wireless Internet provides super fast broadband speed, approaching 2 megabytes per second or faster.
- Wireless Internet is more affordable
-  Wireless Internet is also incredibly responsive, when you call up web pages, download emails, and engage in teleconferencing or video conferencing over the net.
- The wireless Internet broadband service offers rural Web surfers a way to tap into high speed telecommunications
Disadvantages of Wireless:
- someone, within the wireless traffic can hack into your connection.

Advantages of Cable: - High connection speed
- Convenient 
- you are always connected to the internet
- Does not affect your phone line. You don’t need to switch your local phone service provider.
- Connection speed is not affected by the distance from ISP operation center
- Easy setup with self installation kit
Disadvantages of Cable:
- Higher price than dialup and DSL connection
- Higher security risk than dialup or DSL (personal firewall is needed)Not available to all cable TV networks
- Bandwidth is shared over the same cable line.
- Connection speed is affected by the number of people using the internet at the same time in your neighborhood.
- Usually tie with cable TV subscription


Advantages of ADSL: 
- Independent services: Loss of high speed data does not mean you lose your telephone service. Imagine your telephone, television, and Internet access going out when a cable company amplifier/repeater stops working.
- Security: Unlike cable modems, each subscriber can be configured so that it will not be on the same network. In some cable modem networks, other computers on the cable modem network are left visibly vulnerable and are easily susceptible  to break ins as well as data destruction.
- Integration: DSL will easily interface with ATM, Nx64, and WAN technology. Telecommuting may get even easier.
- High bandwidth
- Cheap line charges from the phone company.
- Good for "bursty" traffic patterns

 Disadvantages of ADSL:- Distance dependence: The farther you live from the DSLAM (DSL Access Multiplexer), the lower the data rate.
- Access: rural areas get shorted.
- Limited availability
- No current standardization: Customers may have to buy new equipment to simply change ISPs

Advantages of Fibre:
- Can be used over greater distances due to the low loss, high bandwidth properties
- It can be used for 2km without the use of a repeater
- “Their light weight and small in size, which makes them ideal for applications where running copper wires  would be impractical
- Due to the fibres being non-conductive, it can be used where electrical isolation is needed
- The fibres are do not pose a treat to the environment, such as in a chemical plant where a spark could cause an explosion

Disadvatages of Fibre:
- It is much more costly than other cables to install - It is relatively difficult to install

Methods of Delivery

Outline the methods of delivery of broadband (wireless, cable, ADSL and fibre)? Identify the speed of each method.
Wireless: Wireless is an emerging technology that will soon match and overtake the popularity of other current Broadband types. Connecting to the Internet can be made almost anywhere by accessing 'Hotspots' which are hosted in various locations, so you don't need a telephone or cable line. Wireless technology is similar to Mobile Phone technology, as it adopts a similar methods of transmitting data via radio waves.
Cable: Cable Broadband is made from co-ax material which greatly increases bandwidth limits. Higher speeds and a broader capacity allows users to bundle their Internet with PAY TV and VoIP services which can also run simultaneously through the same connection without interference. Over the previous decade Cable has become a popular alternative for Broadband Internet services and is still rapidly growing. It's available in most metropolitan locations and currently serviced by two Providers, namely BigPond & Optus.
ADSL: ADSL broadband has largely been eclipsed by ADSL2+, which is faster, and now one of Australia’s most popular types. But depending on your user habits, an ADSL connection may be fine – and work out better value.
Fibre: Fibre Broadband uses Fibre Optic cable to deliver data and is able to deliver it faster and also much more of it than can be done with the existing copper wires currently in use.

Broadband

What is broadband? The term broadband describes the wide range of frequencies that can be transmitted through communication channels (i.e. Internet). The wider your bandwidth is, the greater the amount of information that can be transmitted simultaneously.

Best Multimedia Device

 What multimedia device or service would you find it hardest to be without? Discuss.
I would find it most hardest to be  without the Internet I choose this option because this multimedia device enables so many other multimedia devices to be included in the one source for example the multimedia device the ebook this kind of service would be able to be found on the Internet another example is TV this can also be viewed on the Internet but may have a few delays as to when it is screened. It also allows
