Tips & Tricks#74 Transport Protocols via Transport Layer (UDP & TCP)

Prepared by Chai Woon Khai,

The Internet provides a way to get packets (convenient units of data for computers and routers) from any host computer to one or more other host computers. However, the network protocols make no guarantees about delivering a packet. In fact, a packet may get lost, may arrive after others sent later or may be distorted. A packet might even arrive that simply wasn't sent!

UDP (User Datagram Protocol) is an alternative communications protocol to Transmission Control Protocol (TCP) used primarily for establishing low-latency and loss tolerating connections between applications on the Internet.

TCP (Transmission Control Protocol) is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data.
