The following is a valid IP address:
130.154.465.201
FALSE
A simple checksum can detect all 1-bit errors.
TRUE
Which of the following best describes reliable data transfer in the internet (using networking terminology)?
The ability to send and receive information that you are reasonably sure is what was sent, without losing any information.
Suppose that a client application sends a request to a server application at port 80 on a remote server. The server responds to the client’s address at
a port number assigned by the client’s operating system; this number is not used directly by the client application, but is sent to the server along with the original request.
When it comes to pushing data into the internet, _________ is the more effective protocol.
UDP
The UDP protocol provides reliable, connectionless service.
FALSE
It is acceptable to create two TCP connections on the same server/port doublet from the same client with different port numbers.
TRUE
If I want to be fair about my usage of internet resources, I would use the _____ protocol.
TCP
The UDP protocol provides error detection and correction.
FALSE
The UDP protocol provides error detection.
TRUE
The transport layer manages communications from _______ to _______ .
process to process
The TCP protocol provides error detection and correction.
FALSE
The reserved port for FTP data transfer is port
20
The UDP protocol uses a 16 -bit, 1’s complement of the 1’s complement sum to compute the checksum.
TRUE
