TCP (Transmission Control Protocol) provides reliable data transfer between applications at the transport-layer by ensuring that packets are delivered in the correct order and any lost packets are retransmitted. ARP (Address Resolution Protocol) maps IP addresses to MAC addresses for communication on a local network. UDP (User Datagram Protocol) is a connectionless transport protocol that does not provide reliability. DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices on a network.
