Virtual OS Manager (Memory Allocator) / 虚拟操作系统管理器（内存分配器）

Description / 项目描述

English:
A simulation of virtual memory management with page replacement algorithms (FIFO implemented). This project demonstrates how operating systems handle memory allocation, page tables, and swapping between memory and disk.

中文:
虚拟内存管理模拟器，实现页面置换算法（目前完成FIFO）。本项目演示操作系统如何管理内存分配、页表以及内存与磁盘间的交换。

Features / 功能特点
