Questions with Correct Answers | Updated
(100% Correct Answers)
Internet Protocol (IP) Answer: Routes information across networks,
provides an addressing scheme, delivers packets from source to
destination, and serves as a network layer protocol.
Transmission Control Protocol (TCP) Answer: A connection-oriented
protocol that guarantees delivery through acknowledgment and is
widely used for critical applications.
User Datagram Protocol (UDP) Answer: A lightweight,
connectionless protocol used for voice and video applications, which
doesn't send acknowledgments or guarantee delivery.
OSI Model Answer: Consists of Application, Presentation, Session,
Transport, Network, Data Link, and Physical layers.
Network Address Answer: The first two segments of an IP address,
e.g., in 192.168.1.100, 192.168 is the network address.
Host Address Answer: The last two segments of an IP address, e.g.,
in 192.168.1.100, 1.100 is the host address.
Static IPs Answer: Manually assigned to systems by an
administrator.

DHCP Answer: Allows the automatic assignment of IP addresses
from a configured pool by an administrator.
DNS Server Answer: Translates between domain names and IP
addresses.
Port Ranges Answer: 0-1023: well-known ports, 1024-49151:
registered ports, 49152-65535: dynamic ports.
Internet Control Message Protocol (ICMP) Answer: A network layer
protocol used by network devices to diagnose communication
issues.
Bus Network Answer: Connects many devices to a single wire.
Ring Network Answer: Connects devices in a ring where each
device is connected to two others.
Star Network Answer: Connects every device directly to a switch.
Mesh Network Answer: Connects every device to every other
device.
Client/Server Model Answer: Clients communicate directly with
servers, and servers respond directly to clients.
Peer-to-peer Model Answer: Every device acts as both a client and
a server.
