Outside of the Computer
For the lab we took apart a Dell HP-U2106F3.
Inside the Computer
From this view you can see a fan, the tiniest bit of motherboard, the CD drive, the power supply, and the hard disk.
The Motherboard is in essence the frame work upon which the rest of the computers parts either rest on or near. It's one of the first visible things when the computer is opened. It looks like a large green computer chip and that's basically what it is. The other parts are plugged into the board and power it run to them by the small lines on the board. This power, of course, comes from the power supply. Another small feature on the motherboard is a small battery. One would wonder what that is, but it is for powering the computer's internal clock (On Wisegeek. Retrieved October 10 2012, http://www.wisegeek.com/what-is-a-motherboard.htm#).
The crystals on a computer are located upon the motherboard. They appear as small silver bumps. And according to Wikipedia, it helps to keep the clock on a computer correct as well as to stabilize frequencies. These crystals are used in things other than computers, but provide the same function (in Wikipedia. Retrieved October 10 2012, from http://en.wikipedia.org/wiki/Crystal_oscillator).
- Found underneath the cooling units of the computer.
- Looks like a square chip.
- Cemented onto the computer
- The one found in this computer is an Intel Pentium 4.
The Processor of a computer which can also be called a Central Processing Unit, or CPU. It is the main adder and calculator of a computer, performing the basic arithmetic, logical, and input/output operations of the system according to the Wikipedia pages.
RAM (Random Access Memory)
- RAM has 512MB
- Computer has two things of RAM.
- RAM can hold much more information nowadays.
- These particular RAM chips did not have a clear indication of what company made them.
- The RAM is usually found vertically placed on the motherboard, it varies from model to model.
RAM stands for random access memory which is like the computer's short term memory. RAM lets data, that has been stored upon it from anywhere, say cookies from a website, to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order (in Wikipedia. Retrieved October 10 2012, from http://en.wikipedia.org/wiki/Random-access_memory).
- Found under the lid.
- Lid, meaning the top part that is removed to first see all of the inner workings of the computer.
- This particular drive is just a CD drive
The CD drive reads the information coded on CDs and transfers them into information that the computer can read and then use to run programs.
- Found on the left side of the computer
- Has many cords and electrical wires going out of it.
- Puts out 210 watts maximum.
The power supply's job is fairly self-explanatory, it supplies the power to the computer. It supplies to the power to:
- The CD/DVD drive.
- The Motherboard.
- The Hard Disk.
- Anything else requiring power.
- Found next to the CD drive
The hard disk is the core of a computer. It stores information magnetically in a more permanent way than RAM does. It is a secondary storage device which means the computer isn't just doing input/output, it's running a more complex program to find the specified information (in Wikipedia. Retrieved October 10 2012, From http://en.wikipedia.org/wiki/Hard_disk_drive). The hard drive inside this computer could store 80 gigabytes. From the outside it doesn't look like much, just a square box of metal, but when you open it up there is a disk and other complex things that work to code the information. The exact image of what is inside is demonstrated in the picture.
