Network address — the base address of the block (151.4.2.192). All devices in this subnet share this prefix. Cannot be assigned to a host.

Broadcast address — packets sent to 151.4.2.255 are delivered to every device in the subnet. Also reserved — not assignable.

Usable hosts — the 62 addresses between those two that you can assign to servers, VMs, or interfaces.

Subnet mask — 255.255.255.192 is the dotted-decimal equivalent of /26. Older tools and Cisco configs use this format instead of CIDR slash notation.
