### Understanding TCP/IP Protocols: Assurance and Speed in Packet Delivery

**Question:**
Which TCP/IP protocol, which handles and assures the delivery of packets, provides this guarantee? Which protocol offers a quicker delivery time but does not ensure its success?

---

**Explanation:**
In the TCP/IP suite, two key protocols manage the delivery of packets across networks: 

- **Transmission Control Protocol (TCP):** This protocol is responsible for assuring the delivery of packets. TCP establishes a connection between the sender and receiver, ensuring that the data is reliably delivered, correctly ordered, and error-checked.

- **User Datagram Protocol (UDP):** This protocol offers a quicker delivery time but does not guarantee the successful delivery of packets. UDP sends packets without establishing a connection and without performing error-checking, leading to faster transmission times but with the risk of packet loss or errors. 

These two protocols serve different needs depending on the requirements for reliability and speed in data transmission. While TCP is often used for tasks where reliability is crucial (e.g., file transfers, web browsing), UDP is preferred where speed is more critical (e.g., live streaming, online gaming).
