Welcome! Yes, I see you’ve come back for more computer knowledge from the master. Of course I am here to break it all the way down to the basics. Today’s topics are…*drum roll*…removable storage, input/ output devices, printers and troubleshooting. Well these are an easy set of terms. Let’s get to it!
Removable Storage is a used to transfer data from one computer to another. Seems easy enough. Removable storage devices range from the archaic and basically extinct floppy disk to the well known USB flash drive.
Input/ Output Devices
An input device is a device that sends data IN to a computer. While an output device sends data OUT from a computer.
For example a scanner is an input device because it is scanning papers IN to the computer system and a printer is an output device because it is printing papers OUT in a physical copy. Another example is a microphone. A microphone allows the user to speak into the computer, but the speaker allows the user to hear sound coming from the computer. Devices can sometimes be used for both input and output such as touchscreens and PDAs.
Printers are the modern day paper wasters, but we still love them nonetheless. The main types of printers are impact, inkjet, and laser. Impact printers use impact and inked ribbon to imprint. An inkjet printer sprays tiny drops of ink on paper. There are actually 3 main laser printer technologies: Electrophotographic (EP), Hewlett-Packard (HP), and LED process.
The EP technology uses a laser beam producing an electric charge and dry toner that creates a printed image. The HP printer is the same as the EP but there are just minor differences in operating procedures. The LED process uses a light-emitting diode instead of a laser.
Troubleshooting is trying to figure out what is wrong with your computer when it is not working. It’s just a fancy word that means finding the problem and fixing it.
First gather information and ask questions. Try to find out what the issue is and once you do zero in on how to fix it. Try simple approaches such as checking for loose or unplugged cords, uninstalling foreign programs, or cleaning the fan of the computer. If that doesn’t help do some research on the problem and see what online experts have to say. When all else fails call the computer company.
