# ComputerOrganization 🖥️

This repository contains examples and exercises related to computer organization and low-level programming. It includes examples written in C and x86 Assembly language, demonstrating concepts such as endianness and system calls.

## Contents

- `BigLittleendian.c` - A C program to determine the endianness of the system.

- `first.asm` - An x86 assembly program to print a string using DOS interrupts.

### BigLittleendian.c

This C program checks whether the system is using big-endian or little-endian byte order. The program uses a union to store a short integer and a character array, then examines the byte order in memory.

#### Compilation and Execution

To compile and run the `BigLittleendian.c` program:

```bash

gcc BigLittleendian.c -o BigLittleendian

./BigLittleendian 

```

## first.asm

This x86 assembly program prints a string to the console using DOS interrupts. It demonstrates the use of the DOS interrupt 21h to print a string and terminate the program.

Assembly and Execution

1. To assemble and run the print_string.asm program, you need an assembler like MASM or TASM, and an environment to run DOS programs like DOSBox.

```bash

masm first.asm;

```

2. Link the object file:

```bash

link first.obj;

```

3. Run the executable in DOSBox or a similar DOS environment:

```bash

first.exe

```
