Describe the purpose of DHCP in a network.

The purpose of DHCP, or Dynamic Host Configuration Protocol, in a network is to automatically assign IP addresses to devices. It simplifies the management of IP addresses by automatically providing a unique IP to each device connected to the network, eliminating the need for manual configuration. This is essential in dynamic network environments where devices frequently join and leave the network. DHCP not only assigns IP addresses but can also provide other network configuration parameters such as default gateways and DNS server addresses, ensuring that each device is properly configured to communicate on the network with minimal human intervention.

Choosing this option accurately reflects DHCP's primary role in enhancing network efficiency and reducing configuration errors. Other options like providing a secure connection, managing bandwidth, or facilitating remote access do not align with the main function of DHCP and pertain to different network protocols or services.
