why is a computer powerful or what makes a computer powerful?

Answer 1

A "powerful" computer is one that is able to do whatever you need it to do. Usually when measuring the "power" of a computer, you consider three main things. The speed of the processor, the amount of RAM memory, and the size of the hard drive. The larger each is, the more powerful the computer. If you are a "gamer", you would also want to consider the quality of the graphic card.

Answer 2

The capabilities of the finest computer in the world can be brought to naught by a flawed operating system.
A computer can answer yes, or no, and nothing else. All else you percieve as computing power is simply the operating systems ability to crunch those ones(yes) and zeros(no's) and give a user friendly answer by way of the GUI (graphical user interface).
The faster the processor, the ram, and hard drive seek time the easier it is to make an overstuffed OS seem to be operating at very high speeds, but given a "cleaner" OS, such as say LINUX an older "slower" computer with less ram, a slower processor, and a slower hard drive, can actually outperform the supercomputer of the week.
Back when we had to use DOS, I developed a menu program which used a mouse like todays computers do...my nerd friends thought I'd flipped out...what the heck was I trying to do, make it where just anybody could use a computer? Yes.
I went on to develop some very basic programs for playing poker, and a couple of quiz games, I wrote in basic and color basic. I used to enjoy publishing my code so others could learn to use "spagetti code" by building simple programs, or just copying mine, and by doing so they learned the commands needed to play midi music, and make simple animations.
I created a chess program to run under DOS 6.22 which I still can't beat, but it can beat my present PC, even though it runs on a 30 year old XT(pre 286) with 16 meg of ram and a 640meg hard drive, it makes it's moves faster too.
The combination of a fast processor, with a seperate math processor, pipeline and downburst cache, closely managed virtual memory (virtual memory is much slower than ram) fast ram and plenty of it, as fast as possible front side buss, and a harddrive with a super fast seek time, matched to a tweaked and peaked OS, gives you a head start on having a fast and powerful system. Dumping programs you don't use which came with your OS and a good editing of your registry will get you into fast company, watch for memory hogs and find another program which will do the same job, usually better without tying up your resources and you are ready to impress even the guys with the pocket protectors, unless they are into Apple computers, which means they paid way too much for a machine which will run less that 3% of available programming, they used to claim graphics manipulation mad Macs worth having (wrong) now they claim Macs don't get viri (wrong again). Plus it's fun to build your own PC, but I have yet to meet a guy who built his Mac.
What makes a powerful computer? YOU.

Answer 3

A combo of a lot of different things. However the heart of any computer is the CPU and that controls all of the tasks and applications. You can check how buissy you CPU is by ctr alt delete and click on task manager and prosseses. the more percent your CPU is being used up the slower your computer will run. If you have a fas CPU it will run your computer faster and with more appliations open

Answer 4

the computer is powerful because of us because we are the one who is better

Answer 5

It is only as powerful as the operator behind it.....
Garbage in Garbage out......
