Question

The subnet mask of an IP address does which of the following?

A. Provides encryption in a TCP/IP network
B. Defines network and host portions of an IP address.
C. Allows automated IP address configuration.
D. Allows users to use a computer's name rather than its address.

Answer 1

The subnet mask defines network and host portions of an IP address, essential for organizing IP networks and facilitating device communication across subnetworks.

Step-by-step explanation:

The subnet mask of an IP address defines network and host portions of an IP address. The subnet mask is a binary pattern used to separate the IP address into the network address and the host address. This allows for the organization of IP networks and ensures that devices can communicate effectively over different subnetworks. It is an essential component of IP networking but does not provide encryption, allow automated IP address configuration, or translate between a computer's name and its address.
