局域网网络通信问题？ [英] LAN network communication problem ?

问题描述

我想开发一个LAN网络与我的局域网PC通信并远程控制远程局域网PC，即远程局域网桌面监控。但我有一些令人困惑的条款如下：



1.

a的责任是什么？ MAC地址

b。 IP地址

c。和pc端口位置（地址）

建立一个局域网网络？

2. PC的哪个端口（无论是服务器/客户端）是专用的，我们不能在远程通信中使用它们吗？



3.

a的责任是什么？ IP地址

b。 mac地址

c。通信系统中PC的端口地址？



简要说明我需要详细描述IP地址，mac地址，端口地址如何在LAN通信系统中工作？

i wanted to development A LAN network to communicate with my LAN's PC and remotely control the remote LAN pc that is, remote LAN desktop monitoring and control. but i have some confusing terms like below:

1. what is the responsibility of
a. MAC address

推荐答案

我们不做你的作业：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！



如果遇到具体问题，请询问相关问题，我们会尽力提供帮助。但是我们不打算为你做这一切！

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

1）MAC地址 - 硬件地址 - 这是网卡的物理地址。这用于路由器的路由表。它用于为PC提供连接到网络的节点（PC /设备）的物理地址，这可以作为街道上的门牌号码。这是路由器用于将您的计算机映射到IP地址的地址。



2）IP地址 - 网络地址，这是分配给某个节点的地址网络。它用作流量定位器，与网络上的其他设备通信。这些通常由DHCP动态分配或由网络管理员手动分配。这是其他计算机用于在网络上与您联系的地址。



从这些描述中他们可能听起来相同，但差异很大，MAC地址是唯一的，永久性不能更改，IP地址可以更改。



不确定PC端口位置的含义是什么？你的意思是路由器/集线器/交换机/配线架的位置？如果是这样的话，以太网线只能运行最多100米



我无法回答专用端口问题抱歉。

1) MAC Address - Hardware address - this is a physical address of the network card. This is used in the routing table of the router. It is used to give the PC a physical address for a node (PC / piece of equipment) attached to the network, this of this as a house number on a street. This is the address the router uses to map your computer to a IP Address.

2) IP Address - Network addres, this is an address assigned to a node on a network. Its used as a locator for traffic to talk to other devices on the network. These are usually assigned dynamically by DHCP or manually by network admin. This is address that other computers use to contact you on the network.

From these descriptions they may sound the same but big difference is MAC addresses are unique and permanent cannot be changed, and IP addresses can be changed.

not sure what your meaning by PC Port Location? do you mean the location of the router/ hub/switch /patch panel? if so bare in mind ethernet cables can only run a maximum of 100m

and im unable to answer the dedicated ports question sorry.
