What does CSMA/CD stand for in Ethernet networks?
Answer: Carrier Sense Multiple Access with Collision Detection
CSMA/CD is the MAC protocol used in traditional Ethernet to handle collisions by detecting and backing off when two devices transmit simultaneously.
Which type of network topology connects every node directly to every other node?

A full mesh topology connects every node to every other node, providing maximum redundancy but high cabling cost.
What is the purpose of a NAT (Network Address Translation) device?
Answer: Translate private IP addresses to public IP addresses
NAT translates private (internal) IP addresses to a public IP address, allowing multiple devices to share a single public IP.
Which field in an IPv4 header prevents packets from circulating indefinitely on a network?
Answer: Time to Live (TTL)
The TTL field is decremented by each router; when it reaches zero, the packet is discarded to prevent infinite loops.
Which protocol is used to send email from a mail client to a mail server?
Answer: SMTP
SMTP (Simple Mail Transfer Protocol) is used to send outgoing email from a client to a server and between mail servers.
What is the IPv6 equivalent of an IPv4 broadcast address?
