Question #3

3. What are the essential "big picture" hardware pieces a computer must have to be a computer. Explain why each piece is essential.
According to tomshardware.com, every computer needs:
PC case (built in Power supply) = this is to hold all of the component parts and power them
Motherboard = Used to hold and provide links for all of the component parts
Processor = Allows communication between component parts
CPU cooler = prevents overheating of parts and therefore prolongs the life of the CPU
RAM = Random Access Memory - volatile storage of what is being done
Harddrive = permanent storage of what must be done to access component parts
Graphics card = allows visual interface
(CD ROM or DVD Drive and Floppy disk drive) I feel these are optional but most programs come on CD or DVD today
Operating System = Tells what works how
Monitor = allow output
Keyboard = allows input
Mouse = allows input
I also think a Network Interface Card is needed to stay connected, but I don't remember that being mentioned.
Does this answer the question? I sure hope so.
I have to say that understanding how to put parts together on a computer and what each does makes as much sense to me as understanding the putting together of ingredients to a cake. The flour provides the base, the shortening allows it to stay moist, the eggs help coagulate, the baking powder keeps it soft, the baking soda allows it to rise. It still doesn't explain to me why it is a cake. A computer has all of these above named parts - some are needed, some are extra, - but it still doesn't make sense to me that it works together as a unit and what it actually does. Is it because I am a resistant learner? (AM I a resistant learner? - I know I used to be about computers, but am I still?) Or is it still just too imaginary for me? Maybe if I actually had to DO it, physically do it, it might make a difference. I know there have been times when Arthur (my husband) opened the computer case to replace, remove, upgrade, or install and I had no problem understanding what he was doing and why. So why do I feel so confused and overwhelmed now? Maybe it is not yet personally relevant. The good news is that after the series of classes, I know where to find the answers if it ever does become personally relevant.
