Computer Fundamental Assignment

1. Procedure of resetting CMOS password (Step by Step – screen shots required)

Step 1:

Disconnect the main AC power by either shutting off the power button on the back of your power supply or simply pulling out the power cable.

Step2:

Wait a minute to be sure all the capacitors and coils have discharged.

To be really safe you can press the power button which will drain the capacitors for sure.

Step3:

Move the CMOS jumper to the clear position, this is usually done on MSI boards by moving JBAT1 from it's original 1-2 position to 2-3 position as demonstrated in the photo below.If you are not sure or have a non MSI board you must find the correct jumper in your motherboard manual.

Step4:

Press your power button. Press and hold the power button on your computer for about 10-15 seconds (nothing should happen because the power is turned off). This will discharge any remaining power stored in the capacitors. This will make the BIOS reset.

Step 5: Return the CMOS jumper to it's original position.

Step6: Restore power to the system.

2. Report on various types of printersA printer is an output device that produces text and graphics on paper.

Major types of printers can be divided into two main groups: Impact printer and Non-impact printer.

1. Impact printer produces text and images when tiny wire pins on print head strike the ink ribbon by physically contacting the paper.

2. Non-impact printer produces text and graphics on paper without actually striking the paper.

Printers can also be categorized based on the print method or print technology.

The most popular ones are:

1. Inkjet printer, 2. Laser printer, 3. Dot-matrix printer and 4. Thermal printer

Among these, only dot-matrix printer is impact printer and the others are non-impact printers.
