My Lab Report for CSC103

In our lab, we took apart a Dell DHS Optiplex GX270. When we removed the cover, we saw the power supply, the hard drive, the floppy drive, the CD/DVD drive, the system board, the padlock ring, the heat sink and blower assembly, cables, and a battery. A helper taught us that the cables provide power for all of the computer's different functions. He also helped us find the two crystals, located on the motherboard, which tell a processor how fast to go and control the frequency of information. We learned that the motherboard is on the bottom of the computer and has many fine wires on it which send binary information through the computer. In addition, he explained the function of the battery: "Even when the computer is shut off, it stores basic information--such as the date and time. Batteries usually last for 10 or more years."

  • According to WikiAnswers, "A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile, they retain the data even when they do not have power." (in WikiAnswers. Retrieved Feb. 21 2012, from http://wiki.answers.com/Q/What_is_the_function_of_a_hard_disk).
