What do intermediate devices do?

- Connect the individual (end devices) to the network. - They can connect multiple individual networks to form an Internetwork.

What are the criteria to consider when choosing network media?

- What is the maximum distance that the media can successfully carry a signal - What is the environment in which the media will be installed - What is the amount of data and at what speed must it transmitted - What is the cost of the media and installation

What are 5 intermediary devices?

- Wireless Router - Lan switch - Router - Multilayer Switch - Firewall Appliance

What are the advantages to having peer to peer networking?

- easy to setup -less complex -lower cost because network devices and dedicated servers many not be required -Can be used for simple tasks such as transferring files and sharing printers.
