Deloitte Computer Science Quiz-3

Explanation:
Routers in computer networks primarily enable communication between different networks, aiding in the transfer of data between networks and directing data packets to their intended destinations.

Explanation:
IP addresses in computer networks identify and locate devices on a network, facilitating communication between devices and enabling data transfer across the network.

Explanation:
Switches in computer networks direct data packets within a network, facilitating communication between devices within the same network and ensuring efficient data transmission.

Explanation:
Firewalls in computer networks ensure network security and data protection by monitoring and controlling incoming and outgoing network traffic, preventing unauthorized access and potential security threats.

Explanation:
Modems in computer networks primarily convert digital data to analog signals for transmission over communication lines, enabling communication between digital devices and networks.

Explanation:
The Domain Name System (DNS) in a computer network translates domain names into corresponding IP addresses, facilitating the identification and location of devices on the network.

Explanation:
Ethernet cables in a computer network play a crucial role in facilitating the transmission of data between devices on a local network, enabling efficient and reliable data transfer.

Explanation:
Repeaters in a computer network function by regenerating and amplifying network signals to extend their transmission range, ensuring that data signals can travel longer distances without loss of quality.

Explanation:
Gateways in a computer network serve the purpose of facilitating network connectivity and data transfer between different network types, enabling communication between networks with different protocols or architectures.

Explanation:
Network interface cards (NICs)
