Module 1.1: Basic Elements in A Network

Which of the following is a characteristic of a mesh topology?

• All devices are connected to a central hub

• Each device is connected to every other device

• Devices are connected in a circular manner

• Devices are connected in a linear sequence

What is a disadvantage of the ring topology?

• It is expensive due to high cabling costs

• Failure in one node affects the entire network

• It has low bandwidth capacity

• It is difficult to add new devices

In which network topology does a single communication line serve as a backbone for all devices?

• Star

• Ring

• Bus

• Mesh

Which statement about star topology is true?

• It requires fewer cables than bus topology

• It continues to function if the central hub fails

• Each device is directly connected to a central hub

• It is more expensive than mesh topology

Which of the following IP address types is automatically assigned by a DHCP server?

• Static IP Address

• Dynamic IP Address

• Reserved IP Address

• Public IP Address

What is latency in a network?

• The number of users connected

• The time delay in transmitting data from source to destination

• The maximum data rate of a link

• The length of a cable used

Which cable type provides the highest bandwidth and the least signal loss over long distances?

• Coaxial Cable

• UTP

• STP

• Fiber Optic

Which of the following best describes a Metropolitan Area Network (MAN)?

• Connects devices in a small office or home

• Spans across countries and continents

• Covers a city or large campus

• Uses satellite connections for data transfer

What is the primary function of a router in a network?

• Connects devices in the same network

• Assigns IP addresses automatically

• Connects different networks and routes traffic

• Acts as a DNS server
  
  

Which of the following is considered an end device in a network?

• Switch

• PC

• Router

• Hub
