路由器与调制解调器的区别和相同之处是什么？
In IT generally well known names are used to identify devices. This may create some time problems about the issues. One of the most asked question in the network world and at the client side “What is the difference between Modem and Router?”. In this post we will look technical and functional details and compare router and modem.
在IT中，通常使用众所周知的名称来标识设备。 这可能会导致一些时间问题。 在网络世界和客户端，“调制解调器与路由器之间的区别是什么？”是网络世界中最常被问到的问题之一。 在这篇文章中，我们将研究技术和功能细节，并比较路由器和调制解调器。
什么是路由器 (What is Router)
The router is generally used for devices that have the routing function. Routing is managing and transmission IP traffic between different networks. When we make an HTTP request to the poftut.com the IP packets are transmitted between us and the server. The transmission is done by routers.
路由器通常用于具有路由功能的设备。 路由管理和在不同网络之间传输IP通信。 当我们向poftut.com发出HTTP请求时，IP数据包将在我们和服务器之间传输。 传输由路由器完成。
Some devices have heavy routing features and functionalities. These devices have multiple routing protocols like EIGRP, OSPF, BGP, RIP, Static etc. and can manage high bandwidth network traffic. These are real routers used in the enterprise environment. These are Cisco, Juniper etc. routers
一些设备具有沉重的路由特性和功能。 这些设备具有多种路由协议，例如EIGRP，OSPF，BGP，RIP，静态等，并且可以管理高带宽网络流量。 这些是企业环境中使用的真实路由器。 这些是Cisco，Juniper等路由器
But some other devices like end-systems have minimal routing capacity and functionality. This devices have only RIP or static routing. These devices also can not handle high bandwidth traffic for routing.
但是某些其他设备(如终端系统)具有最小的路由容量和功能。 该设备仅具有RIP或静态路由。 这些设备也无法处理用于路由的高带宽流量。
什么是调制解调器 (What is Modem)
The modem is a short form of Modulator-Demodulator. As we expect is changes signal into a different format and change again the same format too. This is done for transmission of data in different ranges without any loss.
调制解调器是调制解调器的简写形式。 正如我们期望的那样，将信号更改为不同的格式，然后再次更改为相同的格式。 这样做是为了在不同范围内传输数据而不会造成任何损失。
Modems was very popular in 2000’s for WAN and MAN connections. Modems are generally used with copper wires and process electrical signals. Most home internet users are using these infrastructure to get an internet connection.
调制解调器在2000年代非常流行用于WAN和MAN连接。 调制解调器通常与铜线一起使用并处理电信号。 大多数家庭互联网用户正在使用这些基础结构来建立互联网连接。
硬件(Hardware)
We will look following hardware for their functionality about modem and router.
我们将关注以下硬件，以了解其有关调制解调器和路由器的功能。
企业路由器 (Enterprise Router)
This type of devices generally used for enterprise networks and provides professional network services like routing. This devices may have modem modules but generall,y they do not used or preferred to days.
这种类型的设备通常用于企业网络，并提供诸如路由之类的专业网络服务。 该设备可能具有调制解调器模块，但是一般来说，它们几天都没有使用或优先使用。
ADSL调制解调器(ADSL Modem)
This is the real modem and used for two decades. Home internet users accessthe internet through this modems with telephone lines with modem functionality of their ADSL modems or routers. This type of devices have very little routing functions but they are called ADSL Routers too.
这是真正的调制解调器，使用了二十年。 家庭互联网用户通过电话线具有其ADSL调制解调器或路由器的调制解调器功能的调制解调器通过该调制解调器访问Internet。 这种类型的设备几乎没有路由功能，但也称为ADSL路由器。
