18 Questions
In which type of communication can data flow in both directions, but not simultaneously?
Half-duplex communication
What type of communication allows data to flow in only one direction at a time?
Simplex communication
What mode of communication enables data to flow in both directions simultaneously?
Full-duplex communication
What type of network is designed to cover a large geographical area like a city or town?
MAN (Metropolitan Area Network)
Which model defines how applications interact over a network?
OSI Model
What type of network is limited to a small area, like a single building or a campus?
LAN (Local Area Network)
What are the disadvantages of a scalable network?
Decreased speed of connection, increased chances of error occurring
How can the problem of decreased speed and transmission errors in a scalable network be overcome?
By using routing or switching devices
What is the main feature of a Peer-To-Peer network?
Equal privilege and responsibilities for all computers
Why is Peer-To-Peer network useful for small environments?
Because it is cost-effective and suits environments with up to 10 computers
What is the main disadvantage of a Peer-To-Peer network?
No dedicated server
What potential issue can arise in a Peer-To-Peer network if a computer with shared resource is down?
Resource unavailability due to the specific computer being offline
What is the primary difference between half-duplex and full-duplex communication modes?
In half-duplex mode, data can be sent and received, but not simultaneously, whereas in full-duplex mode, data can be sent and received simultaneously.
What is an example of a simplex mode of communication?
Radio
What is the benefit of full-duplex mode in terms of channel utilization?
It doubles the utilization of the capacity of the communication channel
How many layers does the OSI model consist of, and what do they perform?
7 layers, each performing a particular network function.
What is the primary function of the OSI model?
To describe how information from a software application in one computer moves through a physical medium to the software application in another computer.
What is an example of a full-duplex mode of communication in real life?
A telephone network, where two people can talk and listen at the same time.
Test your knowledge on full-duplex and half-duplex communication modes. Learn about the differences between the two in terms of sending and receiving data simultaneously. See which mode offers better performance.
