Can I do something like I wrote in my subject? And if so how should I do it ?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

If by twist you mean twisted pair cat5 UTP cable, then yes, but you would need to use a special type called a crossover cable which is wired differently. Some newer interface cards may allow you to do the same with normal "straight through" type. | |||

I don't know what you mean by "twist" (perhaps you could reword your question to include more details?), but you can connect three computers without a hub or switch if one has two network adaptors - you connect each of the other two to the middle one and arrange for it to route packets between the machines as needed. The same for four computers but you'd need one machine to have three network cards or at least two with two network adaptors. Though if you are needing to buy a new network card or two in order to do this, buying a switch would be far far easier as you can grab basic 5-port 100Mbit switches rather cheaply these days. If you can find some old network cards that have thin ethernet (10base2) ports you could connect the machines using those without any sort of switch or hub, but I very much doubt you'll find such cards that will work in a modern machine (the last time I saw a thin-ethernet network it was considered antiquated and IIRC PCI was only just starting to become common at the time) and have good drivers for modern operating systems other than perhaps Linux (you might find drivers for such old devices are still present in the kernel). | ||||

When you say hub, I guess you mean switch. It's been a while since Ethernet switches supplanted Ethernet hubs. I believe the Ethernet ports on modern computers and on Ethernet switches tend to support Auto-MDIX, so you probably don't need a special "twist" (crossover) cable to connect two modern computers together. A four-port fast-Ethernet switch and, if needed, a multi-way power adapter or extension lead, will probably cost you very little and gain you some flexibility. Consider wireless options (802.11, WiFi) too. There's also Ethernet over power cabling (HomePlug) | |||
