Answer 1

1. REPEATER
   Explanation: An electronic device in a communication channel that boosts a signal's strength and retransmits it to increase its range is called a repeater. It needs an electrical power supply because it amplifies the signal. The best networking equipment will therefore be a repeater, which must be positioned along the wire's journey between block offices in order to forward and refresh the signal.
2. SWITCH
   Explanation: Switches expand the network's available bandwidth. Switches lessen the load on each host computer. Switches improve the network's performance. Switch-based networks will see less frame collisions.
3. VoIP
   Explanation: Voice over Internet Protocol is known as VoIP. It's a digital technology that lets you use the internet to make calls instead of a traditional phone connection. VoIP is also frequently referred to as voice over IP, IP telephony, or internet telephony.

   The Mumbai branch's three offices are all effectively connected by the aforesaid layout.
