what does router do and its purpose?

A hardware device designed to take incoming packets, analyzing the packets and then directing them to the appropriate locations, moving the packets to another network, converting the packets to be moved across a different type of network interface, dropping the packets, or performing any other number of other types of actions. A router has a lot more capabilities than other network devices such as a hub or a switch which are only able to perform basic network functions. For example, a hub is often used to transfer data between computers or network devices, but does not analyze or do anything with the data it is transferring. However, a network router may take the data being sent over a network, change how it is packaged and send it to another network or over a different type of network. For example, routers are commonly used in home networks to share a single Internet connection with multiple computers.Below are some additional examples of different types of routers used in a large network. Brouter= Short for Bridge Router, a "brouter" is a networking device that serves as both a bridge and a router. Core router= A core router is a router in a computer network that routes data within a network but not between networks. Edge router= An edge Router is a router in a computer network that routes data between one or more networks.

linux 安全 tcp/ip

In most cases you will need root permission to be able to capture packets on an interface. Using tcpdump (with root) to capture the packets and saving them to a file to analyze with Wireshark (using a regular account) is recommended over using Wireshark with a root account to capture packets on an "untrusted" interface. See the Wireshark security advisoriesfor reasons why.

QT signal / slot mechanism

c++qt 编程算法 linux

QT 是一个跨平台的 C++ GUI 应用构架，它提供了丰富的窗口部件集，具有面向对象、易于扩展、真正的组件编程等特点，更为引人注目的是目前 Linux 上最为流行的 KDE 桌面环境就是建立在 QT 库的基础之上。QT 支持下列平台：MS/WINDOWS-95、98、NT 和 2000；UNIX/X11-Linux、Sun Solaris、HP-UX、Digital Unix、IBM AIX、SGI IRIX；EMBEDDED- 支持 framebuffer 的 Linux 平台。伴随着 KDE 的快速发展和普及，QT 很可能成为 Linux 窗口平台上进行软件开发时的 GUI 首选。

Win32 Linux汇编语法区别

单片机 linux 汇编语言 gcc 编程算法

一、简介作为最基本的编程语言之一，汇编语言虽然应用的范围不算很广，但重要性却勿庸置疑，因为它能够完成许多其它语言所无法完成的功能。就拿 Linux 内核来讲，虽然绝大部分代码是用 C 语言编写的，但仍然不可避免地在某些关键地方使用了汇编代码，其中主要是在 Linux 的启动部分。由于这部分代码与硬件的关系非常密切，即使是 C 语言也会有些力不从心，而汇编语言则能够很好扬长避短，最大限度地发挥硬件的性能。
