"Little Endian" means that the lower-order byte of the number is stored in memory at the lowest address, and the high-order byte at the highest address. For example, a 4 byte Integer
Byte3 Byte2 Byte1 Byte0
will be arranged in memory as follows:
Base Address+0 Byte0
Base Address+1 Byte1
Base Address+2 Byte2
Base Address+3 Byte3
Intel processors (those used in PC's) use "Little Endian" byte order.
"Big Endian" means that the high-order byte of the number is stored in memory at the lowest address, and the low-order byte at the highest address. The same 4 byte integer would be stored as:
Base Address+0 Byte3
Base Address+1 Byte2
Base Address+2 Byte1
Base Address+3 Byte0
Motorola processors (those used in Mac's) use "Big Endian" byte order.
little-endian
There is little endian byte ordering support in Java found in the java.nio package (see ByteBuffer and ByteOrder class).
Endian formats refer to the order in which bytes are arranged within larger data types, such as integers or floating-point numbers, in computer memory. There are two main types: big-endian, where the most significant byte is stored first, and little-endian, where the least significant byte is stored first. The choice of endian format can affect data interpretation, especially in systems that communicate with each other using different byte orders. Understanding endian formats is crucial in programming, networking, and data serialization.
The terms big-endian/little-endian come from Jonathan Swift's Gulliver's Travels. In Lilliput, a royal edict required its citizens to open soft boiled eggs from the small end. In the rival kingdom of Blefuscu, they opened them from the big end, earning them the name Big-endians. In computing, the terms are intended to indicate from which end a multi-byte numeric value is written. With little-endian, the least-significant byte always comes first (thus the value is written in reverse). This makes it much easier to cast from one type to another. For instance, a wide character consumes two bytes (a word). For characters within the ASCII character set, the first byte is always 0x00 while the second byte stores the actual ASCII character code (0x00 to 0xFF). With big-endian notation, casting a wide character to an ASCII character results in the ASCII character always having the value 0x00 because that is the first byte. In little-endian, the bytes are reversed thus the first byte is the ASCII character code.
There are n no. of ways for determining endianness of your machine. Here is one quick way of doing the same.#include <stdio.h> int main() { unsigned int i = 1; char *c = (char*)&i; if (*c) printf("Little endian"); else printf("Big endian"); getchar(); return 0; } In the above program, a character pointer c is pointing to an integer i. Since size of character is 1 byte when the character pointer is de-referenced it will contain only first byte of integer. If machine is little endian then *c will be 1 (because last byte is stored first) and if machine is big endian then *c will be 0.
little-endian
Both little and big endian are still in use today. In big endian the most significant byte is the smallest address stored. In little endian the least significant byte is the smallest address stored.
In a 32-bit word, the decimal value 3 has hex value 0x00000003. Laid out in memory in a little-endian computer, it is 0x03, 0x00, 0x00, 0x00. If you move that to a big-endian computer without reversing the byte order, you get 0x03000000, which is decimal 50,331,648. The correct big-endian representation should have been 0x00, 0x00, 0x00, 0x03.
Big endian does not change the ordering, so it is stored as 0x1234
24.6391 is represented in IEEE real*4 (32-bit real number) as: 0x41c51ce0 (big-endian) 0xe01cc541 (little-endian)
Endianness relates to the order of bytes in a multi-byte value. Humans prefer to work with big-endian notation, such that the value 123 is interpreted as being one-hundred-and-twenty-three. In little-endian notion, 123 would be interpreted as being three-hundred-and-twenty-one. In other words, the significance of the digit positions is completely reversed. With big-endian notation, the most significant digit always comes first. With little-endian notation, the least-significant digit comes first.Note that although the word 'end' usually means final or last, the term derives from Jonathan Swift's novel, Gulliver's Travels, where a civil war breaks out over which end of a soft-boiled egg to crack first; the big end or the little end, analogous to the most-significant or least-significant end of a multi-digit value respectively.

Big-endian byte ordering in Motorola microprocessors is significant because it determines the way data is stored in memory. In big-endian systems, the most significant byte of a multi-byte data is stored at the lowest memory address, which can impact data manipulation and communication with other systems.

Disabling Endian firewall is a little tough. You either need to create an allow rule for all ports, or disable to firewall on outgoing traffic.
