How do TCP and UDP differ in the way they provide reliability for delivery of packets?
How do TCP and UDP differ in the way they provide reliability for delivery of packets?
TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, ensuring reliable delivery of data. UDP, on the other hand, sends packets without any reliability mechanisms, meaning it does not guarantee delivery, order, or error checking. As a connectionless protocol, UDP sends packets to the receiver individually without establishing a connection, making it efficient but less reliable compared to TCP.
B is correct
B is 50% correct, udp sends packets individually not as a stream, fix your effing answers cisco...
This is a question directly from the official Cisco review book "Do I know this already" section. Unlikely an actual exam question.
Ref: CCNA 200-301 Official Cert Guide, Volume 2 “Chapter 1. Introduction to TCP/IP Transport and Applications … Flow Control Using Windowing TCP implements flow control by using a window concept that is applied to the amount of data that can be outstanding and awaiting acknowledgment at any one point in time. … User Datagram Protocol UDP provides a service for applications to exchange messages. Unlike TCP, UDP is connectionless and provides no reliability, no windowing, no reordering of the received data, and no segmentation of large chunks of data into the right size for transmission. …”
B is correct
A little bit confusing…..in a later question it becomes clear that TCP sends as a stream….not UDP.
why not c?
tcp is a connection-oriented protocol
Repeating question
Repeating response.
different answers
B it is.
This is kinda dumb but in my head I just think UDP is fast and dumb, tcp is good/strong, always work for me, always get this right
