1-3 Discuss the relationship between network architecture and protocol
Protocols define how diverse modules interact, and network architecture defines how sets of protocols are organized
1-5 Define the following terms: protocol, connection-oriented protocols, connectionless protocols, and protocol stacks.
Protocols are the special set of rules that end points in a telecommunication connection use when they communicate with each other. Connection-oriented networking protocol establishes a communication session, then delivers a stream of data in the same order as it was sent. Connectionless Protocol is the data communication method in which communication occurs between hosts with no previous setup. And protocol stacks implement a computer networking protocol suite.
1-11 Briefly describe the seven layers of osi protocol hierarchy
The seven layers of OSI protocol hierarchy are:
1. Physical: Transmission method used to propagate bits through a network.
2. Data Link: Frame formatting for transmitting data across a physical communications link.
3. Network: Network addressing and packet transmission on the network.
4. Transport: Data tracking as it moves through a network.
5. Session: Job management tracking.
6. Presentation: Encoding language used in transmission.
7. Application: User network applications and interfacing through the network.
1-21 List and briefly describe the five basic data communications network topologies
Mesh Topology: connected with many redundant interconnections between network nodes.
Star Topology: devices are connected to a central computer, called a hub. Nodes communicate across the network by passing data through the hub.
Bus Topology: a bus is the central cable -- the main wire -- that connects all devices on a local-area network. 4.
Ring Topology: all of the nodes are connected in a closed loop.
Tree Topology: a "hybrid" topology that combines characteristics of linear bus and...
