Data Communication Networking (ITT300)

The distance between a sender and a receiver of a data communication system is 1250 km and the propagation speed is 2.5 x 108 m/s. The system uses 4-bit sequence numbers whenever possible. Ignore waiting and processing delays. Also ignore the overhead due to the header and the trailer and assume no data or control frame is lost or damages during transmission. If each packet carries 1500 bits of data how long does it take to send 10 million bits of data for the following cases: i. If Go-Back-N ARQ protocol is used

Consider as a simple telephone network consisting of two end offices and one intermediate switch with a 1-MHz full duplex trunk between each end office and the intermediate switch. Assume a 4-kHz channel for each voice call. The average telephone is used to make four calls per 8-hour workday, with a mean call duration of 5 minutes. Twelve percent of the calls are long distance. Analyse and determine the maximum number of telephones an end office can support.

A system is using NRZ-I to transfer 10-Mbps data. What are the average signal rate and minimum bandwidth?

NDY Sdn. Bhd. is planning to set up the company's computer network. Form a group which comprise of the maximum of 5 (five) members to write a report to propose a network setup for this organization. The proposal will be presented to the top management for implementation approval.
The following requirements need to be fulfilled:
LAN 1

8 Host: 1 Printer, 3 Workstation, 4 Laptop
Printer and Workstation must be connected to LAN 1 Switch using Wired Ethernet
Laptop must be connected to network using Wireless Ethernet via Access Point
LAN 2
Network Address: 193.16.2.0/24
6 Host: 1 Printer, 3 Workstation, 2 Laptop
Printer and Workstation must be connected to LAN 2 Switch using Wired Ethernet
Laptop must be connected to network using Wireless Ethernet via Access Point
LAN 3
Network Address: 193.16.3.0/24
4 Host: 2 Workstation, 2 Laptop
Printer and Workstation must be connected to LAN 3 Switch using Wired Ethernet
Laptop must be connected to network using Wireless Ethernet via Access Point
All the networks must be connected to a LAN 1 Router (Thus the LAN 1 Router must have adequate port to connect all network together) and all network and equipment in this project must be labelled properly.
