原创 计算机OSI七层和封装过程
最后说一下经常分不清的网桥、网关、和网卡的区别:1、网桥,是把两个不同物理层,不同MAC子层,不同速率的局域网连接在一起。比如说10MB/S与100MB/S的局域网。因为它有储存转化功能。2、网卡是电脑的一个接收信息 转换信息 暂储信息的一个硬件。它是把接受到信息递交给上层,如(CUP)的一个接口。3、网关(Gateway)又称网间连接...

原创 安卓连接云数据库
连接云数据库我想了一下,自己目前就掌握了两种方法,一种是线程,一种是异步。那么哪种方法比较好呢。其实是异步我个人觉得更好,其实异步的连接也是一种线程的方式,不过不够明显。我写了一个登陆的demo. 先说一下单纯的线程方式: package com.example.myphone;import java.io.IOException;import java.io

原创 SharedPreferences
除了SQLite数据库外,SharedPreferences也是一种轻型的数据存储方式,它的本质是基于XML文件存储key-value键值对数据,通常用来存储一些简单的配置信息。其存储位置在/data/data//shared_prefs目录下。SharedPreferences对象本身只能获取数据而不支持存储和修改,存储修改是通过Editor对象实现。实现SharedPreferences存储的

原创 操作系统常考面试题目
1、什么是进程(Process)和线程(Thread)?有何区别? 进程是具有一定独立功能的程序关于某个数据集合上的一次运行活动,进程是系统进行资源分配和调度的一个独立单位。线程是进程的一个实体,是CPU调度和分派的基本单位,它是比进程更小的能独立运行的基本单位。线程自己基本上不拥有系统资源,只拥有一点在运行中必不可少的资源(如程序计数器,一组寄存器和栈),但是它可与同属一个进程的其他的

原创 常考链表的面试题目
题一、 给定单链表,检测是否有环。 使用两个指针p1,p2从链表头开始遍历,p1每次前进一步,p2每次前进两步。如果p2到达链表尾部,说明无环,否则p1、p2必然会在某个时刻相遇(p1==p2),从而检测到链表中有环。http://ostermiller.org/find_loop_singly_linked_list.html这篇文章讲了很多好的坏得相关算法。题
