In data transfer process, which of the following is used for strengthening the signals

The Correct answer is Repeater.

 Key Points

• A repeater is a network device used in the data transfer process to strengthen signals as they travel over long distances in a network.
• The primary function of a repeater is to amplify and regenerate signals, preventing them from degrading over extended cable lengths.
• Signal Strength and Distance: As data travels across a network, the strength of the signal tends to diminish over long distances due to factors like cable resistance and other environmental interferences.
  • In networking, especially with technologies like Ethernet, there are limitations on the maximum distance a signal can travel without significant degradation.

Additional Information

• Firewalls:
  • ​A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
  • Function: Firewalls are primarily designed for security purposes, controlling access to or from a private network while allowing or blocking data packets based on security configurations.
• Hubs:
  • ​ A hub is a basic networking device that connects multiple devices in a LAN, allowing them to communicate with each other.
  • Function: Hubs operate at the physical layer (Layer 1) of the OSI model and simply broadcast data to all connected devices.
• Switching Packets:
  • ​Switching refers to the process of forwarding data packets within a network based on the destination address in each packet.
  • Function: Switches operate at the data link layer (Layer 2) of the OSI model and use MAC addresses to make forwarding decisions.
