First Online Quiz on Computer Networks

Questions and Answers

1.

In computer network, nodes are:
- A.
  
  The computer that originates the data
- B.
  
  The computer that routes the data
- C.
  
  The computer that terminates the data
- D.
  
  All of the mentioned
Correct Answer
D. All of the mentioned

Explanation
In computer networks, nodes refer to any device or computer that is connected to the network. These nodes can perform various functions such as originating the data, routing the data, or terminating the data. Therefore, all of the mentioned options are correct as they represent different roles that nodes can play in a computer network.

What does LAN stand for?
- A.
  
  Local Area Network
- B.
  
  Low Area Network
- C.
  
  Local Arial Network
Correct Answer
A. Local Area Network

Explanation
LAN stands for Local Area Network. It is a network that connects computers and devices within a limited area such as a home, office, or school. This network allows for the sharing of resources such as files, printers, and internet connections. LANs are typically faster and more secure than wide area networks (WANs) because they cover a smaller geographic area.

What does WAN stand for?
- A.
  
  World wide LAN
- B.
  
  Wide area network
- C.
  
  Wide world network
Correct Answer
B. Wide area network

Explanation
WAN stands for Wide Area Network. This is a type of computer network that covers a large geographic area, such as multiple buildings, cities, or even countries. It allows computers and devices to connect and communicate over long distances. Unlike a Local Area Network (LAN) which is confined to a small area, a WAN enables data transmission across a wide range of locations. Therefore, "Wide area network" is the correct answer.

Which of the following are the elements of communication?
- A.
  
  Computer
- B.
  
  Mobiles
- C.
  
  Printers
- D.
  
  Optical Fiber
Correct Answer(s)
A. Computer
B. Mobiles
C. Printers

Explanation
The elements of communication are the means or tools used to transmit information or messages. In this case, the correct answer includes computer, mobiles, and printers, which are all devices commonly used for communication purposes. These devices enable individuals to exchange information, whether it be through written messages, phone calls, or digital media. Optical fiber, on the other hand, is a medium used to transmit data but is not considered an element of communication itself.

Topology defines how devices are connected to the network.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Topology refers to the physical or logical arrangement of devices in a network. It determines how devices are connected to each other and how data flows within the network. Different types of topologies include bus, star, ring, mesh, and hybrid. Therefore, the statement "Topology defines how devices are connected to the network" is true as it accurately describes the role of topology in network connectivity.

Which of the following is not a type of topology?
- A.
  
  Queue
- B.
  
  Star
- C.
  
  Ring
- D.
  
  Bus
Correct Answer
A. Queue

Explanation
The term "topology" refers to the arrangement or structure of a network. In computer networking, a queue is not considered a type of network topology. A queue typically refers to a data structure used to store and manage items in a sequential manner. On the other hand, star, ring, and bus are all types of network topologies commonly used in computer networks.

Communication between a computer and a keyboard involves ______________ transmission.

Correct Answer
Simplex

Explanation
Communication between a computer and a keyboard involves simplex transmission. Simplex transmission is a one-way communication mode where data can only flow in one direction, from the sender to the receiver. In the case of a computer and a keyboard, the computer sends signals to the keyboard to register key presses, but the keyboard does not send any data back to the computer. Therefore, simplex transmission accurately describes the communication between a computer and a keyboard.

Three or more devices share a link in ________ connection:
- A.
  
  Unipoint
- B.
  
  Multipoint
- C.
  
  Point to Point
- D.
  
  None of the above
Correct Answer
B. Multipoint

Explanation
In a multipoint connection, three or more devices share a single link. This means that multiple devices can communicate with each other simultaneously over the same connection. In contrast, a point-to-point connection only allows communication between two devices, while unipoint connection is not a recognized term in networking. Therefore, the correct answer is multipoint.

Is this a star topolgy?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Based on the given question and answer, it is not possible to determine whether this is a star topology or not. The answer "False" could mean that it is not a star topology, or it could mean that the question itself is not asking about a star topology. Without further information, it is not possible to provide a definitive explanation for the given answer.

What are the different forms of data representation?
- A.
  
  Characters
- B.
  
  Text
- C.
  
  Numbers
- D.
  
  Image
Correct Answer(s)
B. Text
C. Numbers
D. Image

Explanation
The different forms of data representation include text, numbers, and images. Text represents information in the form of written words or characters. Numbers represent numerical values used for calculations or measurements. Images represent visual data such as pictures or graphics. These different forms allow for the representation and communication of various types of data in different formats.
