Why do computer manufactures prefer to build computers from separate standard components?
Cost, cost and cost.
When you design a computer it is all about performance, and to sell it, the price need to be competive. If it is better than competitive, and you can make a device with more bells and whistles, better performance, better battery life, bigger disks and still to a lower price, the difference is the profit you can make. Since standard components are produced in large numbers, these are cheaper than those you design yourself, and make just those few you need. So standard components are preferred, until you elect to make something your competitive edge. This you spend your effort at making better and leave all the other things to standards.

What does uniterruptible power supply mean?
An uninterruptable power supply is a power device for a computer (or other things) which is designed never to lose power in the middle of crucial operations. For example, if you're running a computer which is in charge of a critical process and there is a disruption in the power coming into the computer, the uninterruptable PSU (power supply unit) is designed to make sure the computer doesn't stop the process it was working on and lose data.
What determines the physical size of a power supply and the placement of a screw holes?
Case form factor determines the physical size of a power supply and the placement of a screw holes. It can be ATX, microATX, BTX and others.
What component is under the fan and heat sink?
A central processing unit (CPU), is under the fan and heat sink. The processor creates a lot of heat as it works, and would soon burn-out if not cooled.
Is a train ticket machine an input or output device?

Why for an ideal power supply the output voltage is independent of the load?
Obviously, you don't want the voltage to sag. For computer power supplies, you want the power to be even, pure, and clean without any ripple.
Where do you install the PCIe network adapter in a PC?
A person should install a PCIe network adapter in the PCIe network slot on a pc. The PCIE network adapter allows the PC the ability to connect with the Internet.
What are the two reasons to tie cables up and out of the way inside a computer case?
1. It keeps cables out of the way of moving parts (such as drive bays) so they cannot get snagged.
2. It stops the cables moving - preventing short circuits if a cable is worn.
3. It keeps cables away from thermal hotspots such as the CPU or GPU heatsink, which can reach very high temperatures, making the cable isolation brittle
4. It keeps cables from blocking the airflow, required to reach the heatsinks and hard drives. (This also helps keeping the noise down.)
