Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types?

• financial transactions, audio conference, web page

• financial transactions, web page, audio conference

What is a benefit of using cloud computing in networking?

• End users have the freedom to use personal tools to access information and communicate across a business network.

• ^{Network capabilities are extended without requiring investment in new infrastructure, personnel, or software.}

• Technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated.

• Home networking uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables.
