Suppose you wanted to do a transaction from a remote client to a server as fast as possible Would you use UDP or TCP Why?

Answer 1

TCP:

1.reliable transport between

sending and receiving

process

2. flow control: sender won’t

overwhelm receiver

3. congestion control: throttle

sender when network

overloaded

4. does not provide: timing,

minimum throughput

guarantee, security

5. connection-oriented: setup

required between client and

server processes

UDP:

1. unreliable data transfer

between sending and

receiving process

2. does not provide:

reliability, flow control,

congestion control,

timing, throughput

guarantee, security,

or connection setup,

Answer 2

If its speed you want then go for UDP

but if its security and reliablity you want then go for TCP

UDP just pretty much gets the message and sends it off and hopes for the best. Usually its reliable enough.

Whereas TCP does a 3 way handshake for security, then numbers each packet and then sends them off (well theres a bit more than that, but just generally speaking). But it will also resend any packets that the destination didn't recieve.

Answer 3

If its speed you want then go for UDP

but if its security and reliablity you want then go for TCP
