For the Townsville Police Department, I would like to recommend using star topology. According to the facts that I have been found; star topology is one which the hub includes all of the intelligence of the whole system and passes directly all network signals. Because the Townsville Police Department is divided into four district and it covers an area of 100 square kilometres.

Among the network mediums, I suggest that wireless network is most suitable for the Townsville Police Department. In populated areas, wireless network kills the cable costs for the large distance from the server. Wireless also facilitates office relocations and easier to maintain. It makes available real-time data in broader range of coverage areas. It also more secure than the other mediums. So, wireless is the most suitable network medium for Townsville Police Department.

Internet services that may be require

There have many kinds of internet services to access online. They include Dial-up, DSL, Broadband and Wireless Services.

Connection Types Comparison

Dial-up

Dial-up is the basic way of internet services. Generally, its speed less than 56 Kbps. Dial-up speeds can differ according to the quality of the phone-line and the user configurations. There have many dial-up users who familiar with particularly slow speeds for example 28 Kbps on 56k connections. Usually users need to be assigned a different IP number every time you connect providing some anonymity.

Dial-upistheleastexpensive access way of connection, but it also has the least convenient. When you disconnect, you are truly disconnected unlike the always on high speed tactics like cable which create somewhat of a security risk.

DSL

DSL (Digital Subscriber Line) is a high speed telephone line supplying phone-line, television and internet access. A DSL service transmits signals along the same wires that telephony uses, and cable modems that use the same as the cable TV uses. In those cases, the electronic devices that are applied to transmit signals along the wires use different frequencies or channels that do not disturb with other signals on the common wires. So, a DSL Internet service connection can transmit signals along a pair of wires at the same time the wires are being used for a phone line, and cable modems can transmit signals over a cable at the same time the cable is being used to obtain television signals.

DSL is a very distance sensitive medium. DSL providers are only able to offer its facility to locations in its range. The high speed will drop off quite a bit any further from DSL providers. This means that only locations that are close to a DSL hub can even get the top speeds of 3 Mbps to 7 Mbps. Users who live further than the drop-off point will only be able to get the basic DSL plans which offer speeds from 768 Kbps to 1.5 Mbps.
