• A Network Interface Controller (NIC) is a hardware component that enables a computer to communicate on a network.
• TCP/IP stands for Transmission Control Protocol/Internet Protocol.
• TCP provides reliable, ordered, and error - checked delivery of data, while UDP is a connectionless protocol that does not guarantee reliable data transfer.
• A network hub is a simple networking device that acts as a central point for traffic control in a network, forwarding data packets to all connected devices.

Answer:

1. A card that allows computers to communicate on a network
2. Transmission Control Protocol/Internet Protocol
3. TCP ensures reliable data transfer, UDP does not
4. A central point for traffic control in a network
