Questions On Computer Networks

Questions and Answers

1.

What is a Hub?
- A.
  
  A small box with multiple connection points on the front or back
- B.
  
  A type of network cable
- C.
  
  A special computer that has no monitor, keyboard, or pointing device
- D.
  
  A software program
Correct Answer
A. A small box with multiple connection points on the front or back

Explanation
A hub is a small box with multiple connection points on the front or back. It is used to connect multiple devices in a network, allowing them to communicate with each other. The devices can be computers, printers, or any other network-enabled devices. The hub acts as a central point for data transmission, receiving data from one device and sending it to all other devices connected to it. It does not have any intelligence or ability to filter or manage network traffic.

2.

WAN requires the same technology as LAN
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
WAN (Wide Area Network) and LAN (Local Area Network) both require the same underlying technologies, such as Ethernet, TCP/IP, and network switches. The main difference between WAN and LAN is the geographical area they cover. While LANs are confined to a small area like a home, office, or building, WANs cover a larger area, often spanning multiple cities or even countries. However, the basic technologies used in both types of networks are the same, making the statement true.

Peer-to-Peer network are not flexible
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Peer-to-peer networks are actually known for their flexibility. Unlike client-server networks, where all the requests and data flow through a central server, peer-to-peer networks allow direct communication and sharing between individual nodes. This decentralized structure enables greater flexibility in terms of scalability, fault tolerance, and adaptability to changing network conditions. Users can easily join or leave the network without disrupting its functionality. Therefore, the statement that peer-to-peer networks are not flexible is false.

A network of computers and other devices that is confined to a relatively small space?
- A.
  
  Global Network
- B.
  
  Local-Area Network
- C.
  
  Peer-to-Peer Network
- D.
  
  Metropolitan Network
Correct Answer
B. Local-Area Network

Explanation
A local-area network (LAN) is a network of computers and other devices that is confined to a relatively small space. This type of network is typically used within a single building or a small group of buildings in close proximity. LANs are commonly used in homes, offices, schools, and other small-scale environments where devices need to be connected and share resources such as files, printers, and internet access. Unlike global networks or metropolitan networks, LANs have a limited geographical scope and are designed for local communication within a specific area.

  Network Layer
- B.
  
  Presentation Layer
- C.
  
  Application Layer
- D.
  
  Data Link Layer
Correct Answer
B. Presentation Layer

Information can be transmitted via one of_______siganlling methods.
- A.
  
  One
- B.
  
  Two
- C.
  
  Four
- D.
  
  Five
Correct Answer
B. Two
8.

One important benefit that a Hub brings to the home network is?
- A.
  
  Protection against viruses and added security while on the Internet
- B.
  
  Shared (network-attached) storage
- C.
  
  Ability to share files among two, three, or more computers
Correct Answer
B. Shared (network-attached) storage

Explanation
A Hub brings the benefit of shared (network-attached) storage to the home network. This means that multiple computers connected to the hub can access and share files stored on a central storage device. This allows for easy file sharing and collaboration among different devices on the network.
