How is simple parity check related to the two dimensional parity check?
The single parity check uses one redundant bit for the whole data unit. In a two dimensional parity check, original data bits are organized in a table of rows and columns. The parity bit is then calculated for each column and each row.
Suppose that noise changes the data unit 01110000 to 01110011 what will detect the error?
Longitudinal redundancy checking LRC only
What is odd parity even parity?
Priority: Counting number of ones (1s) in the unit of data, since 0 is zero.Example: a unit of data: 1001 (=0x09) where number of 1s is 2 making even parity.So, the parity bit - the most significant bit will be '0' - "even" which makes the byte 0000-1001 or 0x09.Add 1, makes 10 - or xxxx-1010 still 2 bits set, making also even parity 0x0a.Add 2, makes 11 - or 1000-1011 - 0x8bYou can make a simple transistor as a "gate" we call XOR. If one OR the other pin is raised, then raise pin out. If none or both are set, pin out is set low. The difference between OR and XOR is the result of both.But use the "overflow" 4th pin of an OR "gate", and use this as input to the next bit and you "ADD" binary.
What is the largest unit in a data hierarchy?
A record is the largest unit of information in the data hierarchy. The smallest unit in the data hierarchy is called a data field.
Will the outside unit get damaged by not being level?
ouside HVAC unit
What is the basic unit of data in a spreadsheet?
A "cell" is the basic unit of data
Odd parity transmission system is based on the transmission of an odd number of?
odd parity transmission is based on the transmission of an odd number of one bits for each byte or character or minimum data unit. odd parity transmission is used as a simple form of error detection when transmitting data through a medium such as wire. typically a transmission record or packet may be split into eight bit segments with a ninth bit appended to each segment so that nine bit are transmitted for segment. The ninth bit is set to zero or one so that each segment has an odd number of one bits. At the receiving end, each segment is checked to insure that an odd number of bits are set to one. If not, than a transmission error exists and some measure is taken to have the record or packet resent. Parity checking by itself is not fool proof. It can catch the loss of a single bit of data in a byte but if two bits (or an even number of bits) are wrong, no error will be detected as parity will show to be valid.
What is the basic data measuring unit?
Byte=8 Bits, is the basic data measuring unit.
What is protocol data unit?
data reassembled at the destination =))
Can dogs detect alcohol?
If it is a police trained k-nine unit dog, then it can detect alcohol by sense of smell as well as drugs.
What are the functions of the control unit?
a control unit is that part of the possessor in the system unit, where data are controlled as to the amount of data to be processed at a give time by the processor.
Unit of energy a surge protection device can absorb before it can be damaged?
Unit of energy known as a Joule
