Short Answer▾

Name the factors that affect the performance of the network

Explanation

  1. Number of Users: Large number of concurrent users slow response time in a network.
  2. Type of Transmission Medium: Medium defines the speed at which data can travel through a connection.
  3. Hardware: A higher-speed computer with grater storage capacity provides better performance.
  4. Software: Well-designed software can speed the process and make transmission more effective and efficient.

What is Redundancy?

Explanation

  • Redundancy includes extra information for detecting or correcting errors.
  • A shorter group of bits is appended to the end of each unit
  • Extra redundant bits are discarded as soon as the accuracy of the transmission has been determined.
Given the Image is Define the Redundancy
  • Sender adds the redundant bits and the receiver checks the complete bit stream through the checking function.

What is Proxy ARP?

Explanation

  • Proxy Address Resolution Protocol enables the switch to respond to ARP queries for network addresses by giving it an Ethernet media access control address.
    • Switch captures and routes traffic to the intended destination.
    • Used when hosts are on different physical networks without subnet masking.
    • With proxy enabled, ARP broadcasts do not propagate between hosts on different physical networks- hosts thus do not receive a response to their ARP request if the destination is on a different subnet.
    • Allows hosts to communicate with each other through the switch.
  • Allows a subnet to reach remote subnets without using a routing or a default gateway.
Given the Image is Define the IP Proxy ARP (Proxy Address Resolution Protocol)
