🛡 Explain what is the network address and the host address ..

Network Address:
⏺ An address that represents the network as a whole, rather than a specific device within it, such as a family name (e.g., "The Green Family") rather than a specific person's name.
⏺ All parts of the host are zeros (0) such as:
192.168.1.0
10.0.0.0


Host Address:
It is the part assigned to the device within the network, such as a person's name within a family (for example, "Shield" from the Green family), which comes after the network part of the IP address.

An easy example to understand the idea:
Imagine an IP address like a home address:
Street = Network address (e.g. "Palestine neighborhood").
House number = host address (e.g. "House number 7").

Digital example:
If we have an IP address: 192.168.1.7
Subnet Mask: 255.255.255.0 (meaning the first 3 parts for the network, and the last part for the host).

Analysis:
Network address = first 3 parts of IP + last part zero 192.168.1.0
Host address = last part of IP 7.

Another example:
IP: 10.2.0.48
Subnet Mask 255.255.0.0 (first two parts for network, rest for host).
Network address: 10.2.0.0
Host address: 0.0.0.48 (but usually just 48).

short:
⏺ Network address such as city or neighborhood name.
⏺ Host address such as house or apartment number.
⏺ They are identified using the Subnet Mask.

Note:
If Subnet Mask = 255.255.255.0 then:
First 3 digits = network address.
Last number = host address.
