Guys my teacher was 100 percent sure i copied this from the internet and handed it in to her... she gave me a 94 percent but i did this all myself and my dads calling the school today, it isnt the best project but do you guys think i wrote this? its pretty basic stuff to understand and doesnt show all of my knowledge on computers... quite lame how the teacher thinks im dumb :S many errors about parts but who cares not like the teacher knows

Introduction
Hello ladies and gentlemen, my name is ME and while reading this I hope to teach you a lot about computers that you didn’t know before, that is if you aren’t a computer nerd like I am. I also hope to find out what kind of money it takes to run a PC like mine over the course of a year.
First Computers
The definition of the word “computer” is a machine for manipulating data according to a list of instruction or a program, so really us humans are the first computers ever created, but speaking about modern day digital computers the first computer ever made that we have records of is the CER-10, it is the earliest of digital computers ever built, it’s design was based on transistors and vacuum tubes.It was developed over 3 years by 10 technicians, 10 engineers and many other people. The first ever non-prototype model was released in 1963.
But the first mass produced and mass sold PC to the consumer was the IBM model 5100 PC, introduced in 1975 it was the most technologically advanced electronic that was mass produced and sold to the public at the time; the prices are as follows…
RAM BASIC APL Both
16K $8,975 $9,975 $10,975
32K $11,975 $12,975 $13,975
48K $14,975 $15,975 $16,975
64K $17,975 $18,975 $19,975
Computers Nowadays
Modern day computers of this day and age are quite complex compared to other computers even a few months ago, computer technology is so rapidly changing that it is almost impossible to have “the best” computer out there. They say that if you buy a computer at the top of a year in about 3 months the technology will be far outdated.
Average pricing for computers now can be from $499 from low-cost manufacturers like Dell or Acer with or without monitors depending on the package, to a midrange of about $699-$999 from everyday regular manufacturers and for top-of-the line computers the price could go up to tens of thousands of dollars on fully upgraded Apple PC’s. To get the best for anyones money on a computer it is recommended to custom build it yourself, that is if you have the proper knowledge of course.
Parts Of A Computer
There are many parts which create a computer, the main parts of a computer are quite simple to recognize and identify so I will point out the main parts that will make a PC do what it does best… To start you off I have put a basic diagram of the main parts of an average computer, to fully understand the parts you should read the parts descriptions written after the diagram.
Computer Diagram
The CPU (Processor) controls the messages being sent to and from the computer via any peripheral device like a mouse, keyboard, USB portable drive, iPod etc. and tells the rest of the parts of the computer what to do like when to use more power from the video card for games or using more speed when downloading items. The CPU a computer has is based on what socket the compatible motherboard has in it, for the new Intel processors the motherboard uses LGA775 (775 pins on the socket) connection for the CPU, for the new AMD AM2 line of processors the socket is S940 (940 pins on the socket), there are other CPU manufactures but these 2 manufacturers are the leaders in the technology.
The graphics card ( or video card ) controls the quality of the items you see on your monitor, the better the quality of the video card the nicer the view you see on your display whatever it may be. The kind of graphics card a person may use depends on the kind of PC the consumer has purchased and/or needs for his/her use. The newest graphics connection is PCI-Express which offers enough bandwidth and transfer speed for a high-performance graphics card to be able to process beautiful displays.
The RAM (random access memory) is memory allows random data to be saved quickly and/or deleted quickly at random, unlike what the hard drive does. RAM comes in many different varieties but the main ones used now are DDR and DDR2 which each offer different amounts of bandwidth for a PC to run with.
The HDD (hard disk drive or hard drive for short) is the main part of where vital memory is saved on your computer. Some of these saved items are the settings of your PC, video games, videos, music, word files etc. Anything you save on your computer is stored on the HDD. Again as with many parts of a computer, different kinds of HDDs inside a PC are based upon what kind of connection there is on the motherboard, the newest connection is SATA (Serial ATA) which provides a faster speed for data to be transferred throughout a computer.
The optical drive or a CD drive to common folk, reads and/or creates CD’s, DVD’s that you put into the drive. They have massive storage capacities for the biggest of your files and now the new Blu-Ray disks have even more room for high definition applications. There are few connections for optical drives, some of them include IDE and SATA for maximum speed transfer.
Although floppy disk drives (FDD) are currently being phased out right now, they used to be highly used in the 1980’s to store information before CD’s and DVD’s and now even Blu-Ray disks were created. They have very little capacity but served well during their time. They use very old built-in connections to connect to the motherboard called FDE slots which are very fragile and are damaged easily. This is why this drive is not included in my diagram. But if it was, it would be situated in the optical drive cage.
The PSU (power supply) is perhaps one of the least known parts of a computer that is vital for a PC to run. It converts the power from the 120V socket that the PC is connected to into whatever capacity the power supply can handle (ranging from 200Watts up to 1000Watts for modern day computers) then turns it into electrical energy and pulses of energy to power up the components of a computer.
The motherboard, is the base of every computer, it has connections for the CPU (processor socket), sockets for video cards, sound cards, hard drives, optical drives etc. Just think, anything you connect to the PC externally and any component that is inside a computer is in one way or another connected to the motherboard.
There are many more smaller permanently connected parts inside the computer such as the chipset, resistors, capacitors, MOSFETs and many more pieces that control the messages sent around the computer, there are too many to list so I listed the parts of a computer any average consumer would ever need to know about to purchase or upgrade a computer.
All-in-all, these parts work together sending messages and commands to each other to make the computer do what it does for a person who is using it.
Conclusion
Voltage and wattage varies from PC to PC depending on the components in it. Here is a rough estimate of how much it would cost to run an above average PC like mine for 24 hours a day 7 days a week for a whole year considering the CPU voltage being at 1.4V in and out and considering an overall system wattage being at 300W.
Equation
300W = 0.3k W/h
Ontario electricity cost is $0.1001 kW/h
So in 24 hours the cost of a 300W PSU computer is… $0.1001 x 24 = $2.4024
In 365 days the cost of a 300W PSU computer is… $2.4024 x 365 = $876.76 if the computer is running 24 hours a day for 365 days a year.
