A host's network interface card (NIC) accesses the physical network by converting digital data from the host's operating system into electrical signals or radio waves, depending on the type of connection (wired or wireless). The NIC facilitates communication with other devices on the network by handling data transmission and reception, ensuring that packets are correctly formatted and addressed. It plays a crucial role in establishing a connection to local networks or the internet, enabling data exchange between the host and external entities.
The packet is sent using the IP address and MAC address of the default gateway.
Network Specific Routing is a technique in which there is only one entry for all the host connected to the network. Instead of having an entry for each and every hosted connected to the same physical network.
ARP stands for Address Resolution Protocol, a network layer protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.
-The geographic scope of the network -The physical layer implementation -The number of hosts to be interconnected
What is the Network mask of IP 185.185.0.0 in dotted decimal? How do I calculate First host of the major network IP address? What would be my last host of the major network?"
logical address is called as global address and physical address is called as local address .the ip address,which is used by the user in the network is found to be global for use and it is easily identified in any network .physical address is mac address ,which is stored in the nic card,which is mainly used ,when the system is connected in the network using switch
The IP address of a given host might change each time it comes onto a network if it is using a proxy server. A proxy server makes it hard to locate the person using the internet.
You need to connect VMs to internal NAT (should be configured with physical adapter to access physical network). While within NAT VMs are going to have different IP addresses, within physical network (your local network) its IP address is going to be the same.
DHCP Server (Dynamic Host Configuration Protocol)
The main difference is that there is a router place between the untrusted network and the host using a dual-home configuration.

A switch is a network connectivity device and a host is a computer system (client) on a network.
