Shared resources
The shared resources in every department are; router, switch, printer and the wireless access points.
Selection of a high speed color copier printer
Colour Ability Corporation should consider using Lexmark CS410dtn Color Laser Printer.
The printer duplex, USB, Ethernet and wireless printing therefore, supporting network printing in the various departments.
It has a maximum duty of 75000 pages
It has an input capacity of 900 sheets of papers
It is a two sided printer.
Its power consumption is sufficient and has low noise level when operational reducing the power consumption cost for CAC.
It is compatible to windows 10 operating system.

CAC management should consider choosing TPG internet service providers because they are cheap their prices range from $49 to $69 per month and their services are good. They provide web mail access, DNS services and their technical support is good.
Internal services offered by CAC
Amassment of packets from the local area network and directing them to the internet, the router is the device responsible for this ( Chabarek et.al 2008, April).
Integrated Service Digital Network, abbreviated as ISDN, ensures that the information sent through a telephone line reaches the destination as a whole. It reduces noise and information loss as information travels.
Connection of the various subnets to the main network, this is done by the use of bridges.
Dial up Internet Access, CAC is responsible for providing dial up internet access through the use of modems. The modems work under modulation and demodulation of digital computer signals and analog telephone signals (Son, Her and Kim 2011).
Wireless networks famously known as WI-FI. This is where computers are able to access the internet wirelessly through the use of D-Links which are in turn connected to switches (Kim, Lee, Kwon and Yuh 2011).
Amplification of signal during transit from the server to the client, this is done using repeaters installed by CAC.
Wireless Broadband, abbreviated as WiBB, it uses microwave technology to avail internet access for a wide range of area.
|
Are wired connection required? |
Yes. Many wired network connections are required especially in each department to facilitate transfer of large file especially to the server. |
|
Are wireless connections required? |
Yes. Because of the wireless printing by computers in the wireless network in each department. |
|
Wireless standard? |
IEEE 802.11a |

Firewall Required? |

|
Internal or external modem required? |
Yes, wireless modem |
|
Cable Required? |
Yes. Ethernet cables of type CAT 6 should be used for cabling or devices connections |
|
Battery Backup Required? |
No. Each computer should be allocated a Universal Power Supply system. The most appropriate solution in case of black outs and brown outs is a backup automatic generator that will supply power to the whole building. |
The diagram below shows the plan for the implementation of the office network connectivity in each of the floors in Brisbane’s story building.

Private Ip addresses can be identical but in different networks whereas public ip addresses are unique, allocated to each of the devices in the five departments. Private Ip addresses are usually blocked when it comes to internet access or access to other networks they are not allocated for. This enhances the access levels authentication in the various departments. Public ip addresses are either static or dynamic (Ramachandran et.al 2013, September). The static addresses are not shared or changed when surfing the internet, this helps in preventing network attacks to Colour Ability Corporation. The dynamic public ip addresses transforms when one is surfing the internet. This helps in preventing network attacks.
Use of firewalls (Khoumsi, Krombi and Erradi 2014, November), installation of firewalls to filter the intranet or the local area network in the organization and to filter packets during internet access . Firewalls will be able to alert CAC of the anomalies experienced in the network before an attack appears (Wang, Butnariu and Rexford 2011).
The only ip addresses that should be allowed to pass through the firewall are the ones allocated to the various devices in the network design.

The film crew consists of two production assistants, two camera people, a production manager, and a film director. They will only spend two days in a week in the Sydney office.
The following is the specifications form for the devices these employees will require
