All you need to do is run out to CompUSA or go online and purchase a KVM switch. Basically, this will allow you to hook up a mouse, keyboard and monitor to two different machines. Most of the units have a button on the front which will switch from one system to the other, and in most cases you can just press the Ctrl+Alt keys to switch. Here is a link to the type I use (but I use mine to connect 4 systems, you'll only need the one that connects 2 systems).

Good Luck.
If you mean, how do you use one computer to contact another:
Remote desktop software allows you to remotely control one PC from another, or show your PC screen to someone else.
The software is mostly used for remote support and training purposes.
However, this has NOTHING to do with your question about combining computing power of two separate central-processing units.
Linking computers to operate together is called a cluster. There are a few different types of clusters but in the case of a normal user using a couple of home computers it would be a loosely coupled setup. There are a few ways to do this but unless you are doing something such as music production or graphics rendering etc there is no real gain for the average user. The gains are in any aspects of rendering. Such as running a simulation or rendering large graphic set ups.
...using a technology called VNC. I suggest you Google it. Essentially, using software such as RealVNC, you can remotely use your other computers. In addition, there are many VNC clients for some mobile devices, especially the iPhone/iPod touch.
Windows XP has a feature called "Remote Desktop Connection" (it's in the Accessories menu) which does much the same thing.
You need a KVM Switch - this is a Keyboard Video Mouse controller that allows you to switch between computers. You can get models for 2 computers or many.
Networked hub or switch to connect them using network cable.
1. You can use computers to learn new things.
The first connection is into a Cable Modem ... from there the signal can go to a Router and then on to different computers.
To link 2 computers you should have cross cable. Because Serial cable is user to connect 2 or more dissimilar devices. To connect 2 similar devices like computers, Hubs, Switches you should use Cross cable only.In Serial cable 4 pairs of cables are their, 2 pairs for Transmitting and 2 pairs for Receiving the Data. If you use serial cable to connect 2 computers, Conflict will happen while sending and receiving the data. In cross cable 2 pairs of cable will be in a different order so conflict won't happen. So use Cross Cable while connecting 2 similar devices.

Computers are only capable of differentiating between two possible states. That is: a switch is either on or off; a capacitor is either full of charge or it is empty; a score upon an optical disc is either long or short; there is either a flux transition or there is not; there is either a hole punched at a position on a card or there is not. All are valid ways of representing binary values and all are or have been used by computers at one time or another. We use 1s and 0s, but computers cannot; they are simple machines, they have no actual intelligence whatsoever. They have to use mechanic representations.
You can not use an iPod with two libraries. You are only allowed to have one iTunes library in you iPod at one time.
yes
you can only use 1 computer but the iphone can go to 2 computers
The best table to use for multiple computers is one that is large and flat and has enough room for computers to be spaced at least twelve inches a part.
Connect your printer to one of computers, and share it for all computers in your network. Or if your printer has its own network interface, connect it directly to the router and use it (you might have to configure it for your network settings).
Yes because my friend has world of warcraft on his computer and then he downloaded it onto mine you just cant have both computers use the same WoW account or one person will get kicked off of the server
Yes, you can if both computers have/had windows xp.
No.
You would use cross-wired cables to connect 2 computers together.
You could either burn a CD,use a pen drive,or conect the 2 computers via LAN and config it such tht u have access to both the computers, or if the 2 computers are far away u vud create a VPN via the internet!!!
To hook up two computers to one modem, you get a router.
No, it depends on the computer. DDR2 RAM is only for newer computers (Core 2, &tc.)
