Older "computers" using relay technology tended to be spread out, the results of one operation "cascading" down to the next relay and so on. this is how the calculators worked using a mechanical relay design. Instructions to these had to be at a very low level and were difficult to program. Many of the older computers used "breadboards" with many jumper wires to determine the path of the cascading depending on the results of an operation. Some computers were built to solve specific problems with specific inputs and producing specific outputs. One of the earliest computers was used to calculate artillery trajectories only.
The central processing unit design provided a standard "language" to input information, process it and get the results. This frees people to develop better input and output devices which worked as long as they communicated with the CPUvia its standard requirements. It also made it possible to upgrade the CPU since it had a standard software and hardware interface to the rest of the computer.

PC computer stands for what?
PC stands for "Personal Computer". At present, this term refers to the fact that the device can be operated by any individual without having to possess much computer/software knowledge as it was in the past. It can include desktop computers as well as laptop computers and tablet computers. The software is another thing, although closely related. It includes things like operating systems--Windows, MAC, etc.--which are necessary for the computer to work and perform. Other software are programs like Microsoft Office, CD-ROM games, etc. that can add to the computer's task abilities or simply add to the entertainment that it provides. In the past, a PC user had to create his or her own programs in order for the computer to operate. Now, operating systems and the rest of the software facilitate the process of using a computer and this is why the term PC is now more vast, as I mentioned in the beginning.
Where to connect the mouse on the desktop computer?
There are two different possiblities for connecting a mouse to a desktop PC computer. In the past there were what were called PS2 mice that plugged into a special circular connector on the back of the computer. You don't see these on current computers. On current computers you connect a mouse to any USB port. I don't know about Apples, even thought they were the innovaters that came up with the mouse.
