ENG301 (Business Communication)

Fall 2009

Assignment # 1 Total Marks: 15

Due Date: 21/10/2009


To asses students’ knowledge of the subject and to motivate them towards conceptual knowledge and practical application of the subject.


  1. Late assignments will not be accepted.
  2. If the file is corrupt or problematic, it will be marked zero.
  3. Plagiarism will never be tolerated. Plagiarism occurs when a student uses work done by someone else as if it was his or her own.
  4. If any assignment is found copied work, no marks will be awarded and the case may be referred to the head of the academics for disciplinary action.
  5. No assignment will be accepted via e-mail.
  6. The file should be in Word doc form; the font color should be preferably black and font size can be 12 Times New Roman.

Question No.1 (5)

Which theory of communication do you prefer from three theories of communication present in your course and why?

Question No.2


Describe the traits of a good communicator. (5)


What is the role of proximity and artifacts in non verbal communication? (5)

key points for Q3 of IT 430

Bus network topology
In local area networks where bus technology is used, each machine is connected to a single cable. Each computer or server is connected to the single bus cable through some kind of connector. A terminator is required at each end of the bus cable to prevent the signal from bouncing back and forth on the bus cable. A signal from the source travels in both directions to all machines connected on the bus cable until it finds the MAC address or IP address on the network that is the intended recipient. If the machine address does not match the intended address for the data, the machine ignores the data. Alternatively, if the data does match the machine address, the data is accepted. Since the bus topology consists of only one wire, it is rather inexpensive to implement when compared to other topologies. However, the low cost of implementing the technology is offset by the high cost of managing the network. Additionally, since only one cable is utilized, it can be the single point of failure. If the network cable breaks, the entire network will be down.

Star network topology
In local area networks where the star topology is used, each machine is connected to a central hub. In contrast to the bus topology, the star topology allows each machine on the network to have a point to point connection to the central hub. All of the traffic which transverses the network passes through the central hub. The hub acts as a signal booster or repeater which in turn allows the signal to travel greater distances. As a result of each machine connecting directly to the hub, the star topology is considered the easiest topology to design and implement. An advantage of the star topology is the simplicity of adding other machines. The primary disadvantage of the star topology is the hub is a single point of failure. If the hub were to fail the entire network would fail as a result of the hub being connected to every machine on the network.

Ring network topology
In local area networks where the ring topology is used, each computer is connected to the network in a closed loop or ring. Each machine or computer has a unique address that is used for identification purposes. The signal passes through each machine or computer connected to the ring in one direction. Ring topologies typically utilize a token passing scheme, used to control access to the network. By utilizing this scheme, only one machine can transmit on the network at a time. The machines or computers connected to the ring act as signal boosters or repeaters which strengthen the signals that transverse the network. The primary disadvantage of ring topology is the failure of one machine will cause the entire network to fail.
