1. A network must be able to meet a certain number of a criteria to be good - Performance - Reliability - Security - All of the above 2. Any communication that involves two parties needs two addresses: name the 2 addresses - Source address and destination address 3. Topology of a network is the…… of the relationship of all the links devices to one another - Geographical representation - Geometrical representation - Graphical representation - 3D presentation 4. A ……… is produced when two different basic network topologies are connected. Star ring or star bus. - Hybrid topology 5. The key elements of a protocol. Match the definition - Semantics: section bits - Syntax: format of data - Timing: when data should be sent & how fast they can be sent 6. A ….. network consists of two or more star topologies connected using a bus trunk. - Star bus network 7. The ……. Can use the entire capacity of the channel to send data in one direction - Simplex mode 8. In bus topology a ….. acts as a backbone to link all the devices in a network - One long cable 9. A multipoint connection in one which ….. share a single link - 2 devices - 1 device - More than 2 device - No device 10. The various addresses used in the TCP/IP layer is given. Match the following - Network: 32bit IPv4 address - Datalink: 48 bit MAC address - Application: User-friendly address - Transport: 16-bit port numbers 11. Each device has a dedicated point-to-point link only to a central controller, usually called a hub. No direct link to each other - Star - Bus - Mesh - Ring 12. A ….. consists of two or more star topologies connected using a multi-station access unit as a centralized hub - Star ring 13. The category into which a network falls is determined by its …. - Make - Place - Size - Shape 14. If communication is complex, the task is divided between different layers, and each layer is governed by a protocol, the process is called ….. - Protocol layering 15. …. Represents an agreement between the communicating devices. Without this, two devices may be connected but not communicating - Protocol 16. ….. are the exchange of data between two devices via some form of transmission medium such as a wire cable - Data communications 17. The only physical path by which a message travels from sender to receiver - Transmission medium 18. In ……. Mode, the entire capacity if a channel is taken over by whichever of the two devices is transmitting at the time and in …. Both stations can transmit and receive simultaneously - Half duplex , full duplex 19. Every device has a dedicated point-to-point link to every other device in…. connection - Star - Bus - Mesh - Ring 20. Each device has a dedicated ….. connection with only the two devices on either side of it is - One point - Point to point - Multi point - None
