Output Devices

Printer- A Printer is a type of an output device that is able to print paper documents. This including text, images or sometimes a combination of both. The two main common type's of printers are the inkjet and laser printers. Inkjet printers are mostly used by consumers whereas the laser printers are used by typical businesses. To make the printer work and to do the basic task that is required such as printing the Printer has to be set up to a PC device to pick up signal from the work done on the computer to have work send through to the printer. Basically when setting up a printer its just like setting up a PC and connecting it to a WiFi spot where many PC's are able to work in that area together. This is when the Printer is set up directly as a stand alone device on the network itself.





Monitor-A monitor is a device which displays videos and graphic information generated through a video card. Monitors are similar to televisions but display information at a much higher resolution. A monitor is also known as a screen, display and a video display. The Monitor connects to the HDMI port on the computer, which is a compact audio/video interface which transfers video data and audio data onto the monitor screen. Monitors display external devices to the computer case and they connect to the PC via cables to a port on the video card or motherboard. This is an essential part of the computer system. There are two major types of monitors such as LCD and the CRT. CRT monitors look much like old fashioned televisions and are very deep in size. LCD monitors are much thinner and they use less energy and provide better digital graphics. Most monitors are in widescreen format and they range in sizes from "17" to "24" or more. This is a diagonal measurement from one corner of the screen to the other.



Speakers/Sound - A speaker is a software programme that is used when the computer gives the speakers commands to make the vocal sound higher. It is a hardware device connected to the computer's sound card and it outputs sounds generated to the computer. Computers are rated in frequency response such as total harmonic distortion, and Watts. It is a rate of measurements between between the highs and lows of the sounds the speaker produces. Like the total harmonic distortion is the amount of distortion created by the speaker which amplifies the signal whereas the Watts is the amount of amplification available for the speakers to produce. When a person is trying to connect the speakers to the computer there should be two wires that come out of the speaker, one wire should be connected to the left speaker but the wires on the right of the speaker have knobs on them where the wires connect from. The other wire though should have a mini plug connector which connects to the back of the computer. For powered speakers there will also be a power cord that needs to be connected to a wall outlet or surge protector. When the speakers at the back of the computer connect the speakers to the line out or sound out this is usually connected to the light green knob where the wire is connected to the speaker to make the volume sound work. After the speakers have been connected it would be advisable to adjust the volume to your liking to make sure the volume is not too high or not too low. The user can do this by adjusting the volume knob.
