What other problems does TCP solve besides guaranteed delivery?

In addition to guaranteeing data delivery, TCP solves the following tasks:

• Packet ordering: TCP ensures that data is received in the same order it was sent.
• Flow control: TCP regulates the data transmission rate to prevent overwhelming the receiver.
• Congestion control: TCP adapts the transmission speed based on network conditions to prevent congestion.
• Error detection: TCP uses checksums to verify data integrity.
• Connection establishment: TCP establishes a reliable connection through a three-way handshake before data transfer.

These mechanisms make TCP a reliable protocol for data transmission over networks.
