# What is a low order byte?

## What is a low order byte?

The low-order byte would be the byte that contains the smallest portion of the value. For example, if you have a 16-bit int , and the value is 5,243, you’d write that in hex as 0x147B. The high order byte is the 0x14, and the low-order byte is the 0x7B.

What is upper and lower byte?

A byte is eight contiguous bits starting at any logical address. A word thus contains 16 bits. The bits of a word are numbered from 0 through 15; bit 0 is the least significant bit. The byte containing bit 0 of the word is called the low byte; the byte containing bit 15 is called the high byte.

What are higher order bits?

In computing, the most significant bit (MSB) is the bit position in a binary number having the greatest value. The MSB is sometimes referred to as the high-order bit or left-most bit due to the convention in positional notation of writing more significant digits further to the left.

### How do you get high byte and low byte?

In hexadecimal, your number is 0x8000 which is 0x80 and 0x00. To get the low byte from the input, use low=input & 0xff and to get the high byte, use high=(input>>8) & 0xff .

What is lowest order bit?

The lower-order nibble is the first 4 bits. The last 4 bits is the higher-order nibble.

Which is the largest byte?

yottabyte
As of 2018, the yottabyte (1 septillion bytes) was the largest approved standard size of storage by the System of Units (SI). For context, there are 1,000 terabytes in a petabyte, 1,000 petabytes in an exabyte, 1,000 exabytes in a zettabyte and 1,000 zettabytes in a yottabyte.

## What are high and low bytes?

A byte is eight contiguous bits starting at any logical address. The bits of a word are numbered from 0 through 15; bit 0 is the least significant bit. The byte containing bit 0 of the word is called the low byte; the byte containing bit 15 is called the high byte.

How are 16 and 32 bit numbers stored?

In little endian machines, last byte of binary representation of the multibyte data-type is stored first. On the other hand, in big endian machines, first byte of binary representation of the multibyte data-type is…

What is the type of 0xff?

Well, 0xff is the hexadecimal number FF which has a integer value of 255. And the binary representation of FF is 00000000000000000000000011111111 (under the 32-bit integer).

### Which is the low order digit of an int?

The “low-order digit” of the int would be the one on the far right, which has value 7, and the “high-order bytes” of the int would be the other three values, which are all zeros. In actuality, on most systems a char represents a single byte (8 bits), and an int is represented by four bytes (32 bits).

What’s the difference between a high order and a low order byte?

The low-order byte would be the byte that contains the smallest portion of the value. For example, if you have a 16-bit int, and the value is 5,243, you’d write that in hex as 0x147B. The high order byte is the 0x14, and the low-order byte is the 0x7B.

Which is the least significant byte in an integer?

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 such as: 01001010 00001111. The low order byte is 00001111.

## What’s the Order of the Little and Big bytes?

The “little” end byte, the lowest or least significant byte, is 0x11, and the “big” end byte, the highest or most significant byte, is 0x44. The two memory storage patterns for the four bytes are: Four-Byte Integer: 0x44332211
