Before transmission the data unit 01110000 changes to 011100001 for error-checking purposesWhich redundancy checking method was used in this case?
Vertical redundancy check (VRC)
What transmission synchronization methods uses the cyclic redundancy check method for error checking?
Synchronous
Why do you need another checking mechanism at the transport layer?

Which statements best describes redundancy checking?
Redundancy checking is a technique used to detect errors or errors in a data transmission. It involves adding extra bits to the data to create a checksum or parity. The receiver then checks for errors by recalculating the checksum or parity and comparing it to the received value. If they do not match, an error is detected.
Suppose that noise changes the data unit 01110000 to 01110011 what will detect the error?
Longitudinal redundancy checking LRC only
What protocols includes extensive error checking to ensure that a transmission is sent and recieved without mistakes?
TCP
What is a Cyclic Redundancy Check?
Sadly, this means there is probably an error on your drive. The computer can't read the part of the disk that the file is on. You might want to try some recovery software and buy a new hard drive because your drive might fail all together soon. This has happened to me twice.Cyclic Redundancy Checking (CRC) is a mathematical method for checking the validity of data sent over networks and read from storage devices such as hard and optical drives.A Google search of Cyclic Redundancy Checking will reveal a plethora of articles written on this topic; so many in fact that attempting to create an in-depth answer without plagiarizing is difficult.Please reference the Relevant answers and Sources and related links below for more on this topic.
What is the difference between TCP and UDP socket?
TCP and UDP are both communication network protocols. TCP protocol in its essence is to guarantee delivery of information, and in the order sent. UDP protocol is lighter, by fact of not checking for the connection to be ready to receive on the other end, not checking if the information getting to the other end is correctly received.
Is this run time checking mechanism done by c plus plus?
There is no such thing as a runtime checking mechanism in C++. The compiler can only catch compile time errors. You must provide any additional checks yourself, to handle any exceptions that may occur at runtime. Failure to handle an exception results in an exception error at runtime. The end result is that the program crashes but, if debug information is available, you can easily locate the source of the exception and thus determine how best to provide a handler for it. But this mechanism is not handled by C++ itself, it is handled by the debugger.
Is DNS connectionless or connection-oriented?
DHCP is a connectionless protocols. In general, any protocol that is based on TCP port alone is a connection-oriented protocol while any protocol that is based on UDP port alone is a connectionless protocol. And a protocols that can work on both TCP and UDP port can be either a connection-oriented or a connectionless protocol depending upon the which protocol is used (TCP or UDP). For checking other protocols if they are connection-oriented or connectionless check http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
What is the number known when you a packet source?
A number that is produced by a mathematical calculation on a packet at its source and checked against the same calculation at the destination is used as an error checking mechanism. What is this number known as?
What is loop checking in dcs explain with diagram?
its nothing but just to loop and check the answer with the corresponding alpha co-ordinate. It can also be simply under stood as the way of checking the mechanism with the use of loop. And the point to be noted is that all loop check are reversible up to a limit. Just press F4.
