Lower order and higher-order bytes are the terms used while computing calculations in a programming language. Usually, numbers are written from left to right. The left is the most significant bit, and it is written first. For example, if we consider your paycheck, then you would be happier if the number the first digit increases instead of the last digit. This is what is referred to as "significance" of a digit. The bits present in computer memory are written usually with a base 2 (for binary, the base is considered as 2). So, the least significant bit is represented as one. The next bit is represented as two or 2'1 and the next one as 2'2'1 and so on.. For example, if we consider 2 bytes of memory, which represents a 16-bit number, then one byte will hold at least eight significant bits, and the other byte will hold the most significant 8 bits. The byte that contains the most significant 8 bits is called the higher-order byte and the one that contains the least significant bits is called the higher-order byte. read less

In Simple way : To understand High/Low-order bytes/bits, consider int as an example. int is 4 bytes in length. The 1st byte is the low-order byte, whereas the 4th byte is the high-order byte. This is the same for bits. For example, still using the int example, the 1st bit is the low-order bit, whereas...

One Nibble is 4 bit's in length. 2 nibbles make a byte. The lower-order nibble is the first 4 bits. The last 4 bits is the higher-order nibble. read less

in binary number system 8 bits are taken as a byte. in 0ne byte the first 4-bits from MSB side are treated as higher order bytes and second half that is 4-bits from LSB side are taken as Lower order.

We generally write numbers from left to right, with the most significant digit first. To understand what is meant by the "significance" of a digit, think of how much happier you would be if the first digit of your paycheck was increased by one compared to the last digit being increased by one. The bits...

We generally write numbers from left to right, with the most significant digit first. To understand what is meant by the "significance" of a digit, think of how much happier you would be if the first digit of your paycheck was increased by one compared to the last digit being increased by one. The bits in a byte of computer memory can be considered digits of a number written in base 2. That means the least significant bit represents one, the next bit represents 2´1, or 2, the next bit represents 2´2´1, or 4, and so on. If you consider two bytes of memory as representing a single 16-bit number, one byte will hold the least significant 8 bits, and the other will hold the most significant 8 bits. Figure shows the bits arranged into two bytes. The byte holding the least significant 8 bits is called the least significant byte, or low-order byte. The byte containing the most significant 8 bits is the most significant byte, or high- order byte. read less

This depends on processors sapose iam using intel processors which follows low order motrolla follows high order technically we colled as little enidian big enidian this is like storage types

The low byte is the byte that holds the least significant part of an integer. If you think in terms of writing a bit pattern on paper, the low byte is the rightmost eight bits. A short holds a 16-bit pattern .

Many data types need more than 1 bytes to store, example int needs 4 bytes, out of these 4 bytes (for the int) the byte which stores the least significant part of the int is called low-order and the one which stores the most significant part is called high-order. The order in which these are stored depends...

Many data types need more than 1 bytes to store, example int needs 4 bytes, out of these 4 bytes (for the int) the byte which stores the least significant part of the int is called low-order and the one which stores the most significant part is called high-order. The order in which these are stored depends on your CPU architecture and differs from one architecture to other. These are also called big endian and little endian (and many more combinations) and plays significant role when transferring binary data from one system to other with different hardware architecture. read less
