You need a crossover cable you want to connect two computers without a switch. If you want to use more than two computers (with switch) you have to use a straight pair cable. ---- Ethernet (up to 100 Mbit) communicates on four of the eight wires available. Two of the wires are used to transmit data, and two are to receive. Wires 1 and 2 transmit while wires 3 and 6 receive. With this in mind, on a straight through cable the wires are in the same position on both ends of the cable. On a crossover cable the wire that is in position one connects to position three on the other side, and the wire in position two connects to position six on the other end.

A patch cable is a network cable that is used to connect a PC to a hub, switch, or router. A crossover cable is used to connector two PCs into the simplest network possible.but on the other side cross cable is just different then patch and used to connect different devices.
Technically:
A straight-through cable is used when connecting a computer to an external device, such as a switch or router.
A cross-over cable is used where you are connecting a device directly to another device. Such as a computer to a computer, a router to a router.
Finally, one you didn't mention but I thought you should know about, is the Rollover cable. This is also known as a "Console" cable and is used to manage a network interface, most commonly on high end (Cisco, etc.) routers, switches and firewalls.
In reality:
Cross-over [UTP] cables are used for everything except console cables. This is to eliminate crosstalk.
First of all, look up some diagrams. They are wired differently. A straight through cable has the same sequence of wires at either end and connects two unlike nodes; for instance, your computer and your router, or your computer and the wall jack. A crossover connects two like nodes: two routers, for example. The transmission between two like nodes is different, requiring a different cable (the corossover).
we use cross over cable for connecting the same device such as computer and computer, computer and router, etc. straight through is use for connecting different device such as computer and switch, router and switch, etc.
The crossover cable is used to connect two computers. The straight cable is used to connect computer to a switch.
Straight Cable Is used to connect two different peripherals such as switch or PC & Crossover Cable is used to connect two same devices such as PC-PC or switch-switch.
Crossover
Some are a straight through network cable, some are crossover.
what is different between cross cabling and straight cabling ANSWER: a crossover cable is used to connect like devices, like a router to a router, but a straight through cable is used to connect dissimilar devices, like a router to a computer.
Straight through ethernet cable (CAT 5/5e/6)
How can I configure straight through cable?
A crossover cable is used when connecting 2 computers together and a straight cable is used to connect a computer to a networking device like a network switch or router. This has to do with the send/receive pins of the cords, obviously when you need to connect 2 computers together you dont want them to be both sending through the same pin, so they are swapped so that what one computer sends comes through the receive port of the other computer. Networking devices dont need this as they are designed to work with straight cables.
To connect two devices of the same type together. e.g. You would use a crossover cable to connect a router to another router, a switch to another switch or a computer to another computer. If you are connecting diferent devices together, such as a router to a switch, a straight through cable should be used.
When using a straight through cable for networking, only 3 pairs are used.
PATCH CABLE Patch cables provide a short-range connection, while longer Ethernet cables (usually Category 5, Category 5e, or Category 6) are used to connect to a hub up to 100 meters away.
A straight-through ethernet cable.
Crossover cables are used when you are connecting two devices of the same type together. e.g. connecting two routers or two switches or two computers. A straight through cable is used to connect devices of different types. e.g. a computer to a switch or router. Using the correct cable is less important these days though as most networking devices have the capability to auto-sense what cable is being used and what cable is needed. The devices can simply change their configurations to whatever is needed to make the connections work. This technology is called Auto-MDIX (Media Dependant Interface Crossover).
You need to use a straight type of connection. 568A or 568B depending which type your network is using.
