INSY 3303 FINAL - SCOTT JOHNSON VERIFIED ACCURATE
STUDY GUIDE
1. Access Point: is a radio receiver that acts as a switch or a hub in Ethetnet LAN
How you connect a wireless device to a wired network.
2. Application Architecture: The way in which the functions of application layer software are spread among
clients and servers in a network.
1. Presentation logic
2. Application logic
3. Data access logic
4. Data Storage
3. Attenuation: Loss of power in a signal as it travels from the sending device to the receiving device
Fix by using repeater
4. Backbone ( BN ): a larger, central network connecting several LANs, other BNs, MANs, and WANs. Routes and
forwards messages and passes content
Distribution layer in a building. (Building
Network) Most common topology: Star
Topology
5. Baselining: a process of trying to gain information about your current network.
when designers must review the list of applications that will use the network and identify the location of each, and the
information is added to the emerging network documentation
6. Building Network (Distribution Layer): Distributes network traflc to and from the LANs

,Switched BN
Second network architecture component
7. Campus Network
(Core layer): Connects all the buildings on one campus.
Routed BN
Third network architecture component

, Usually faster than the backbones we use inside buildings because they typically carry more traflc than they do.
8. Circuit Loading: the amount of data transmitted on a circuit
build for the peak, 3x the peak
9. Content Caching: Storing other people's Web data that is closer to your users
You install a content engine (also called a cache engine) close to your Internet connection and install special content
management software on the router
-It can save your content to other people's stutt
10. Content Delivery: special type of Internet service that works in the opposite direction.
Rather than storing other people's Web files closer to their own internal users
11. CPE ( Customer Premises Equipment ): the equipment that is installed at the customer location.
device resides at the customer site (connects w/ MPLS service provider)
12. Data Flow: The movement of data among processes, stores, sources, and
destinations Simplex: one-way transmission, radios and TV
Half Duplex: two-way transmission, but only in one direction at a time
Full Duplex: transmit in both directions
13. Dedicated Circuit: A circuit that runs from a breaker box to specific outlets.
14. ESP ( Encapsulating Security Payload ): encrypts IP packet and encapsulates it when the
VPN software receives the Packet.
