The Portion of the IP Address that identifies the host or router on the network is called the?
- A.
Subnet
- B.
Hostid
- C.
Networkid
- D.
MAC address
Correct Answer
B. HostidExplanation
The hostid is the portion of the IP address that identifies the host or router on the network. It distinguishes one device from another within the same network. The hostid is an essential component of the IP address and is used for routing and communication purposes. Unlike the networkid, which identifies the network itself, the hostid is unique to each device within that network. The MAC address, on the other hand, is a physical address assigned to each network interface card and is used for identifying devices on a local network, rather than on the internet.Rate this question:

The __________Protocol is a conectionless protocol. Every packet is independent and has no relationship to any packet.
- A.
TCP
- B.
IP
- C.
ISO
- D.
Security
Correct Answer
B. IPExplanation
IP (Internet Protocol) is a connectionless protocol where each packet is independent and has no relationship to any other packet. It is responsible for addressing and routing packets across the internet. Unlike TCP (Transmission Control Protocol), which is a connection-oriented protocol that ensures reliable and ordered delivery of data, IP does not establish a direct connection between the sender and receiver. Instead, it breaks the data into packets, assigns them an IP address, and sends them across the network independently. This allows for faster and more efficient transmission of data, but it also means that packets can arrive out of order or get lost.Rate this question:
