A subnetwork or a logical division of an IP network is called a:

• A. Subnet
• B. Subnet Mask
• C. Subnetting
• D. Star Topology

Answer: (A)

A subnet is a subnetwork or logical division of an IP network. It represents a smaller network created within a larger one to organize addressing, improve routing efficiency, and limit broadcast domains. A subnet is identified by a network address and a subnet mask (or prefix length), which together define which portion of an IP address refers to the network and which part identifies hosts within that network. For example, 192.168.1.0/24 designates a subnet where the first 24 bits are the network portion, with hosts ranging from 192.168.1.1 to 192.168.1.254. The subnet mask 255.255.255.0 expresses the same boundary in dotted notation. The other terms are different concepts: a subnet mask is the bitmask used to separate network and host parts, not the subdivision itself; subnetting is the process of creating subnets; star topology is a type of physical network layout.
