What does the term 'localhost' refer to?

The default gateway
Loopback or 127.0.0.1
The primary DNS server
The DHCP server

The correct answer is: Loopback or 127.0.0.1

'Localhost' refers to the loopback IP address 127.0.0.1, which is assigned to the device's own network interface. This means when the term 'localhost' is used, it is referring to the device itself and not to any external network. Option A, the default gateway, is the IP address of the router that connects the local network to the internet. Option C, the primary DNS server, is responsible for translating domain names into IP addresses. Option D, the DHCP server, is responsible for assigning IP addresses to devices on the network. None of these options accurately describe the term 'localhost'.
