How can you can connect PC to switch with straight or cross-over cable, what is the difference between these two ways, Straight through cable vs Crossover cable? Why are their two types of cables? What do they do?Straight through cable means, the cable wire goes through straight, transmission wires over to the reception end. You use a crossover cable when you are connecting two PCs together directly (NIC to NIC). To connect Router to Router and Computer to Computer need Crossover and the usually the rest need Straight-through cable.

You use a straight-through cable when there is a hub, switch or router between the two or more PCs (NIC-Hub/Switch/Router-NIC). The is no difference in speed, it’s just a method of communicating. It depends on the hardware, all you need is either a free LPT or com port on each computer and a cable plugged into these ports between each computer.

The simple answer is a crossover cable is used when you are connecting two PCs together directly (NIC to NIC), to connect two computers to each other, you use a crossover cable. When two crossover cables are connected in series, as when going through a patch panel, the result would no longer be a crossover.

Take a good look at the picture above, it shows what I mean. In a straight through cable, both ends are arranged as end A, while in a crossover cable, one end is arranged as end B.

This can also help if you want to make a cable yourself

Reply With Quote In order to connect two computers with crossover cables, you must set their IP addresses to be in sequential order. For example:

Recently I connected my Laptop & my PC via a straight ethernet cable. I used the ip adress 192.168.1.2, subnet mask 255.255.255.0, default gateway 192.168.1.3 for my PC & 192.168.1.3, subnet mask 255.255.255.0, default gateway 192.168.1.2 for my Laptop. At first when I need to backup my data to PC, Both system behaved well connected & I transfered all my data to PC. But after formatting my laptop when I try to transfer data again to my Laptop from my PC, it doesnt work any more. Actually it connects for only some 30 secs- 1 min & at the middle of transfer the conection breaks. It shows the message that it couldnt find the network path. I disabled my Antivirus firewall & my windows firewall both, but still the problem persists. somebody pls help….

Connecting two computer’s without a switch or hub, needs a Cross cable and not a straight cable… Also try to crimp the RJ45 connectors again, seems a bit loose… Also give only IP address and subnet mask, Gateway is not required. Will not do any harm but still… All the best

straight cable work once & I have transfered around 250 GB of data. This time also it connects, but after sometime connection breaks. What may the reason for breaking the connection???

Check the connections proper At the back of the Connecters, it may be Loose,for connecting this Seem to be the Only reason , other than that , i dont think Anything else would be Causing this problem

I already checked the connection…Its well fixed….May it be due to any kind security settings of Windows???? By the way, I also have an Beetel 450BX1 wifi router….can it be any help to transfer my files from one system to another??? My PC connected with it via LAN & Laptop connected with it via WiFi….

You’re using a wifi router, to connect the PC and Laptop so your PC will go with the straight cable, and laptop with wifi. Did you change anu configurations on your PC or Wifi? Check workgroup of your laptop an PC it should be same, Also configure wifi router to give IP Addresses automatically, that it make use of DHCP server. It will avoid configuration settings

Does any one have any idea how can i extend my ethernet cable beyond 100 meters between my computer and router/modem? According to my knowledge is concern the maximum size of an ethernet cable length comes around 100 meters. So ant information related to this issue would be appreciated.

You can extend your ethernet cable beyond 100 meters by adding a switch or a hub in between of both ends.

You can also opt for Ethernet Extenders. Ethernet Extenders are also known as network extenders which are used to extend an Ethernet segment beyond its normal distance limitation of 100 meters.

In situation where I have access to one ethernet cable between two end points, is there a way to multiplex so it functions like two independent (lower bandwidth) ethernet cables? Perhaps some sort of multiplexer sitting at both end points, each with three ethernet ports, one goes to the cable, two others are the virtual cable end points.

A network switch is a broad and imprecise marketing term for a computer networking device that connects network segments.The term commonly refers to a Network bridge that processes and routes data at the Data link layer (layer 2) of the OSI model. Switches that additionally process data at the Network layer (layer 3 and above) are often referred to as Layer 3 switches or Multilayer switches.Not necessarily. You can buy physical cable splitters which enable you to run two 10/100 Mbps Ethernet links (each link only needs two pairs) on one regular four pair Ethernet cable. No switch, no power needed. Caveats: Obviously will not work for GigE, which uses all four pairs. May or may not work for 10/100 Mbps Ethernet, depending on distance, cable qualityA network switch is a broad and imprecise marketing term for a computer networking device that connects network segments.The term commonly refers to a Network bridge that processes and routes data at the Data link layer (layer 2) of the OSI model.
