What is the difference between a bit a byte a word and a word size?
The word may be fixed or variable in length. The word length depends upon the number of bits or characters in a word. The number of bits varies from 4, 8, 12, 16, 32 etc., up to 64 i.e., the word may be as long as 64 bits or as short as 8 bits. A byte is usually shorter than a word, typically consisting of 8 bits.
How many bits and bytes are there in a word?
Data structures containing such different sized words refer to them as WORD (16 bits/2 bytes), DWORD (32 bits/4 bytes) and QWORD (64 bits/8 bytes) respectively.

What is double-word in PLC?
A double-word corresponds to the word length of 32 binary characters. A double-word also has the size of 2 words, 4 bytes, or 32 bits. Further units are kilo-bit or kilo-byte, which stand for 210, or 1024 bits, and the mega-bit or mega-byte which stands for 1024 kilo-bits. 2.3.5 BIT AdDRESS.
What is a bit byte word?
A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).
What is the different between byte and bit?
So, bits and bytes are both units of data, but what is the actual difference between them? One byte is equivalent to eight bits. A bit is considered to be the smallest unit of data measurement. Computers also send and receive data as ones and zeroes—bits.
How many bytes is a double word?
4 bytes
Fundamental Data Types A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).
What is the size of byte word and double word in bits?
A byte is 8 bits, a word is 16 bits, and a double word is 32 bits.
What is bit and byte in PLC?
Concepts of bits and words – Ladder Logic Tutorial In a PLC, the processor memory consists of hundreds or thousands of storage locations. When we have eight bits, they are called a byte. Two bytes, or 16 bits, form a word, and usually this is how we refer to memory locations within a PLC.
How big is a double word in bytes?
A word also has the size of 2 bytes or 16 bits. A double-word corresponds to the word length of 32 binary characters. A double-word also has the size of 2 words, 4 bytes, or 32 bits. Further units are kilo-bit or kilo-byte, which stand for 2 10, or 1024 bits, and the mega-bit or mega-byte which stands for 1024 kilo-bits.
How many words are in a double word?
Two bytes are called a word and two words are called a double word which is four bytes (32-bit) and a quad word is eight bytes (64-bit). A byte is 8 bits and is 2^8 power which is 256. The number of binary numbers 8 bits in size is one of 256 values starting at 0 and going to 255.
When do you use bit byte and word?
In connection with programmable controllers, terms such as BIT, BYTE and WORD are frequently used in the explanation of data and/or data processing. Bit is the abbreviation for binary digit. The BIT is the smallest binary (bivalent) information unit, which can accept a signal status of “1“ or “0“.
Which is the smallest address of the two pertinent bytes?
The numbering of words results in a word address. Note: The word address is always the smallest address of the two pertinent bytes when using words, e.g. input word (IW),output word (QW), bit memory word (MW), etc. (e.g. With a word that comes from IB2 and IB3, the address is IW2).
